Introduction
The Intel® Xeon® Processor E5-1600/E5-2600/E5-4600 Product Families Datasheet Volume One provides DC specifications, signal integrity, differential signaling
specifications, land and signal definitions, and an overview of additional processor
feature interfaces.
The Intel® Xeon® processor E5-1600/E5-2600/E5-4600 product families are the next
generation of 64-bit, multi-core enterprise processors built on 32-nanometer process
technology. Throughout this document, the Intel® Xeon® processor E5-1600/E52600/E5-4600 product families may be referred to as simply the processor. Where
information differs between the EP and EP 4S SKUs, this document uses specific Intel®
Xeon® processor E5-1600 product family, Intel® Xeon® processor E5-2600 product
family, and Intel® Xeon® processor E5-4600 product family notation.Based on the
low-power/high performance 2nd Generation Intel® Core™ Processor Family
microarchitecture, the processor is designed for a two chip platform consisting of a
processor and a Platform Controller Hub (PCH) enabling higher performance, easier
validation, and improved x-y footprint. The Intel® Xeon® processor E5-1600 product
family and the Intel® Xeon® processor E5-2600 product family are designed for
Efficient Performance server, workstation and HPC platforms. The Intel® Xeon®
processor E5-4600 product family processor supports scalable server and HPC
platforms of two or more processors, including “glueless” 4-way platforms. Note: some
processor features are not available on all platforms.
These processors feature per socket, two Intel® QuickPath Interconnect point-to-point
links capable of up to 8.0 GT/s, up to 40 lanes of PCI Express* 3.0 links capable of
8.0 GT/s, and 4 lanes of DMI2/PCI Express* 2.0 interface with a peak transfer rate of
5.0 GT/s. The processor supports up to 46 bits of physical address space and 48-bit of
virtual address space.
Included in this family of processors is an integrated memory controller (IMC) and
integrated I/O (IIO) (such as PCI Express* and DMI2) on a single silicon die. This single
die solution is known as a monolithic processor.
Figure 1-1 and Figure 1-2, shows the processor 2-socket and 4-socket platform
configuration. The “Legacy CPU” is the boot processor that is connected to the PCH
component, this socket is set to NodeID[0]. In the 4-socket configuration, the “Remote
CPU” is the processor which is not connected to the Legacy CPU.

Enhanced Intel
SpeedStep® Technology
Allows the operating system to reduce power consumption when performance is
not needed.
Execute Disable Bit
The Execute Disable bit allows memory to be marked as executable or nonexecutable, when combined with a supporting operating system. If code
attempts to run in non-executable memory the processor raises an error to the
operating system. This feature can prevent some classes of viruses or worms
that exploit buffer overrun vulnerabilities and can thus help improve the overall
security of the system. See the Intel® 64 and IA-32 Architectures Software
Developer's Manuals for more detailed information.
Flit

This chapter describes the interfaces supported by the processor.
2.1
System Memory Interface
2.1.1
System Memory Technology Support
The Integrated Memory Controller (IMC) supports DDR3 protocols with four
independent 64-bit memory channels with 8 bits of ECC for each channel (total of
72-bits) and supports 1 to 3 DIMMs per channel depending on the type of memory
installed. The type of memory supported by the processor is dependent on the target
platform:
• Intel® Xeon® processor E5 product family-based platforms support:
— ECC registered DIMMs: with a maximum of three DIMMs per channel allowing
up to eight device ranks per channel.
— ECC and non-ECC unbuffered DIMMs: with a maximum of two DIMMs per
channel thus allowing up to four device ranks per channel. Support for mixed
non-ECC with ECC un-buffered DIMM configurations.
2.1.2
System Memory Timing Support
The IMC supports the following DDR3 Speed Bin, CAS Write Latency (CWL), and
command signal mode timings on the main memory interface:
• tCL = CAS Latency
• tRCD = Activate Command to READ or WRITE Command delay
• tRP = PRECHARGE Command Period
• CWL = CAS Write Latency
• Command Signal modes = 1n indicates a new command may be issued every clock
and 2n indicates a new command may be issued every 2 clocks. Command launch
mode programming depends on the transfer rate and memory configuration.

PCI Express* Interface
This section describes the PCI Express* 3.0 interface capabilities of the processor. See
the PCI Express* Base Specification for details of PCI Express* 3.0.
2.2.1
PCI Express* Architecture
Compatibility with the PCI addressing model is maintained to ensure that all existing
applications and drivers operate unchanged. The PCI Express* configuration uses
standard mechanisms as defined in the PCI Plug-and-Play specification.
The PCI Express* architecture is specified in three layers: Transaction Layer, Data Link
Layer, and Physical Layer. The partitioning in the component is not necessarily along
these same boundaries. Refer to Figure 2-1 for the PCI Express* Layering Diagram.
Figure 2-1.

PCI Express* uses packets to communicate information between components. Packets
are formed in the Transaction and Data Link Layers to carry the information from the
transmitting component to the receiving component. As the transmitted packets flow
through the other layers, they are extended with additional information necessary to
handle packets at those layers. At the receiving side, the reverse process occurs and
packets get transformed from their Physical Layer representation to the Data Link
Layer representation and finally (for Transaction Layer Packets) to the form that can be
processed by the Transaction Layer of the receiving device.

2.2.1.1
Transaction Layer
The upper layer of the PCI Express* architecture is the Transaction Layer. The
Transaction Layer's primary responsibility is the assembly and disassembly of
Transaction Layer Packets (TLPs). TLPs are used to communicate transactions, such as
read and write, as well as certain types of events. The Transaction Layer also manages
flow control of TLPs.
2.2.1.2
Data Link Layer
The middle layer in the PCI Express* stack, the Data Link Layer, serves as an
intermediate stage between the Transaction Layer and the Physical Layer.
Responsibilities of Data Link Layer include link management, error detection, and error
correction.
The transmission side of the Data Link Layer accepts TLPs assembled by the
Transaction Layer, calculates and applies data protection code and TLP sequence
number, and submits them to Physical Layer for transmission across the Link. The
receiving Data Link Layer is responsible for checking the integrity of received TLPs and
for submitting them to the Transaction Layer for further processing. On detection of TLP
error(s), this layer is responsible for requesting retransmission of TLPs until information
is correctly received, or the Link is determined to have failed. The Data Link Layer also
generates and consumes packets which are used for Link management functions.
2.2.1.3
Physical Layer
The Physical Layer includes all circuitry for interface operation, including driver and
input buffers, parallel-to-serial and serial-to-parallel conversion, PLL(s), and impedance
matching circuitry. It also includes logical functions related to interface initialization and
maintenance. The Physical Layer exchanges data with the Data Link Layer in an
implementation-specific format, and is responsible for converting this to an appropriate
serialized format and transmitting it across the PCI Express* Link at a frequency and
width compatible with the remote device.
2.2.2
PCI Express* Configuration Mechanism
The PCI Express* link is mapped through a PCI-to-PCI bridge structure.
PCI Express* extends the configuration space to 4096 bytes per-device/function, as
compared to 256 bytes allowed by the Conventional PCI Specification. PCI Express*
configuration space is divided into a PCI-compatible region (which consists of the first
Intel® Xeon® Processor E5-1600/E5-2600/E5-4600 Product Families
Datasheet Volume One
27
Interfaces
256 bytes of a logical device's configuration space) and an extended PCI Express*
region (which consists of the remaining configuration space). The PCI-compatible
region can be accessed using either the mechanisms defined in the PCI specification or
using the enhanced PCI Express* configuration access mechanism described in the PCI
Express* Enhanced Configuration Mechanism section.
The PCI Express* Host Bridge is required to translate the memory-mapped PCI
Express* configuration space accesses from the host processor to PCI Express*
configuration cycles. To maintain compatibility with PCI configuration addressing
mechanisms, it is recommended that system software access the enhanced
configuration space using 32-bit operations (32-bit aligned) only.
See the PCI Express* Base Specification for details of both the PCI-compatible and PCI
Express* Enhanced configuration mechanisms and transaction rules.
2.3
DMI2/PCI Express* Interface
Direct Media Interface 2 (DMI2) connects the processor to the Platform Controller Hub
(PCH). DMI2 is similar to a four-lane PCI Express* supporting a speed of 5 GT/s per
lane. This interface can be configured at power-on to serve as a x4 PCI Express* link
based on the setting of the SOCKET_ID[1:0] and FRMAGENT signal for processors not
connected to a PCH.
Note:
Only DMI2 x4 configuration is supported.
2.3.1
DMI2 Error Flow
DMI2 can only generate SERR in response to errors, never SCI, SMI, MSI, PCI INT, or
GPE. Any DMI2 related SERR activity is associated with Device 0.
2.3.2
Processor/PCH Compatibility Assumptions
The processor is compatible with the PCH and is not compatible with any previous MCH
or ICH products.
2.3.3
DMI2 Link Down
The DMI2 link going down is a fatal, unrecoverable error. If the DMI2 data link goes to
data link down, after the link was up, then the DMI2 link hangs the system by not
allowing the link to retrain to prevent data corruption. This is controlled by the PCH.
Downstream transactions that had been successfully transmitted across the link prior
to the link going down may be processed as normal. No completions from downstream,
non-posted transactions are returned upstream over the DMI2 link after a link down
event.
2.4
Intel QuickPath Interconnect
The Intel QuickPath Interconnect is a high speed, packetized, point-to-point
interconnect used in the 2nd Generation Intel(r) Core(TM) Processor Family. The
narrow high-speed links stitch together processors in distributed shared memory and
integrated I/O platform architecture. It offers much higher bandwidth with low latency.
The Intel QuickPath Interconnect has an efficient architecture allowing more
interconnect performance to be achieved in real systems. It has a snoop protocol
28
Intel® Xeon® Processor E5-1600/E5-2600/E5-4600 Product Families
Datasheet Volume One
Interfaces
optimized for low latency and high scalability, as well as packet and lane structures
enabling quick completions of transactions. Reliability, availability, and serviceability
features (RAS) are built into the architecture.
The physical connectivity of each interconnect link is made up of twenty differential
signal pairs plus a differential forwarded clock. Each port supports a link pair consisting
of two uni-directional links to complete the connection between two components. This
supports traffic in both directions simultaneously. To facilitate flexibility and longevity,
the interconnect is defined as having five layers: Physical, Link, Routing, Transport, and
Protocol.
• The Physical layer consists of the actual wires carrying the signals, as well as
circuitry and logic to support ancillary features required in the transmission and
receipt of the 1s and 0s. The unit of transfer at the Physical layer is 20-bits, which
is called a Phit (for Physical unit).
• The Link layer is responsible for reliable transmission and flow control. The Link
layer’s unit of transfer is 80-bits, which is called a Flit (for Flow control unit).
• The Routing layer provides the framework for directing packets through the
fabric.
• The Transport layer is an architecturally defined layer (not implemented in the
initial products) providing advanced routing capability for reliable end-to-end
transmission.
• The Protocol layer is the high-level set of rules for exchanging packets of data
between devices. A packet is comprised of an integral number of Flits.
The Intel QuickPath Interconnect includes a cache coherency protocol to keep the
distributed memory and caching structures coherent during system operation. It
supports both low-latency source snooping and a scalable home snoop behavior. The
coherency protocol provides for direct cache-to-cache transfers for optimal latency.

2.5
Platform Environment Control Interface (PECI)
The Platform Environment Control Interface (PECI) uses a single wire for self-clocking
and data transfer. The bus requires no additional control lines. The physical layer is a
self-clocked one-wire bus that begins each bit with a driven, rising edge from an idle
level near zero volts. The duration of the signal driven high depends on whether the bit
value is a logic ‘0’ or logic ‘1’. PECI also includes variable data transfer rate established
with every message. In this way, it is highly flexible even though underlying logic is
simple.
The interface design was optimized for interfacing to Intel processor and chipset
components in both single processor and multiple processor environments. The single
wire interface provides low board routing overhead for the multiple load connections in
the congested routing area near the processor and chipset components. Bus speed,
error checking, and low protocol overhead provides adequate link bandwidth and
reliability to transfer critical device operating conditions and configuration information.
The PECI bus offers:
• A wide speed range from 2 Kbps to 2 Mbps
• CRC check byte used to efficiently and atomically confirm accurate data delivery
• Synchronization at the beginning of every message minimizes device timing
accuracy requirements
Note:
The PECI commands described in this document apply primarily to the Intel® Xeon®
processor E5-1600/E5-2600/E5-4600 product families. The processors utilizes the
capabilities described in this document to indicate support for four memory channels.
Refer to Table 2-1 for the list of PECI commands supported by the processors.

PECI Client Capabilities
The processor PECI client is designed to support the following sideband functions:
• Processor and DRAM thermal management
• Platform manageability functions including thermal, power, and error monitoring
— The platform ‘power’ management includes monitoring and control for both the
processor and DRAM subsystem to assist with data center power limiting.
• Processor interface tuning and diagnostics capabilities (Intel® Interconnect BIST).

2.5.1.1
Thermal Management
Processor fan speed control is managed by comparing Digital Thermal Sensor (DTS)
thermal readings acquired via PECI against the processor-specific fan speed control
reference point, or TCONTROL. Both TCONTROL and DTS thermal readings are accessible
via the processor PECI client. These variables are referenced to a common
temperature, the TCC activation point, and are both defined as negative offsets from
that reference.
PECI-based access to the processor package configuration space provides a means for
Baseboard Management Controllers (BMCs) or other platform management devices to
actively manage the processor and memory power and thermal features. Details on the
list of available power and thermal optimization services can be found in
Section 2.5.2.6.
2.5.1.2
Platform Manageability
PECI allows read access to certain error registers in the processor MSR space and
status monitoring registers in the PCI configuration space within the processor and
downstream devices. Details are covered in subsequent sections.
PECI permits writes to certain Memory Controller RAS-related registers in the processor
PCI configuration space. Details are covered in Section 2.5.2.10.
2.5.1.3
Processor Interface Tuning and Diagnostics
The processor Intel® Interconnect Built In Self Test (Intel® IBIST) allows for in-field
diagnostic capabilities in the Intel® QPI and memory controller interfaces. PECI
provides a port to execute these diagnostics via its PCI Configuration read and write
capabilities in the BMC INIT mode. Refer to Section 2.5.3.7 for more details.
2.5.2
Client Command Suite
PECI command requires at least one frame check sequence (FCS) byte to ensure
reliable data exchange between originator and client. The PECI message protocol
defines two FCS bytes that are returned by the client to the message originator. The
first FCS byte covers the client address byte, the Read and Write Length bytes, and all
bytes in the write data block. The second FCS byte covers the read response data
returned by the PECI client. The FCS byte is the result of a cyclic redundancy check
(CRC) of each data block.
2.5.2.1
Ping()
Ping() is a required message for all PECI devices. This message is used to enumerate
devices or determine if a device has been removed, been powered-off, etc. A Ping()
sent to a device address always returns a non-zero Write FCS if the device at the
targeted address is able to respond.
2.5.2.1.1
Command Format
The Ping() format is as follows:

Device Info
The Device Info byte gives details regarding the PECI client configuration. At a
minimum, all clients supporting GetDIB will return the number of domains inside the
package via this field. With any client, at least one domain (Domain 0) must exist.
Therefore, the Number of Domains reported is defined as the number of domains in
addition to Domain 0. For example, if bit 2 of the Device Info byte returns a ‘1’, that
would indicate that the PECI client supports two domains.

All clients that support the GetDIB command also support Revision Number reporting.
The revision number may be used by a host or originator to manage different command

second byte of the GetDIB() response. The ‘Major Revision’ number in Figure 2-7
always maps to the revision number of the PECI specification that the PECI client
processor is designed to. The ‘Minor Revision’ number value depends on the exact

2.5.2.3
GetTemp()
The GetTemp() command is used to retrieve the maximum die temperature from a
target PECI address. The temperature is used by the external thermal management
system to regulate the temperature on the die. The data is returned as a negative
value representing the number of degrees centigrade below the maximum processor
junction temperature (Tjmax). The maximum PECI temperature value of zero
corresponds to the processor Tjmax. This also represents the default temperature at
which the processor Thermal Control Circuit activates. The actual value that the
thermal management system uses as a control set point (TCONTROL) is also defined as a
negative number below Tjmax. TCONTROL may be extracted from the processor by
issuing a PECI RdPkgConfig() command as described in Section 2.5.2.4 or using a
RDMSR instruction. TCONTROL application to fan speed control management is defined in

Package Configuration Capabilities
Table 2-6 combines both read and write services. Any service listed as a “read” would
use the RdPkgConfig() command and a service listed as a “write” would use the
WrPkgConfig() command. PECI requests for memory temperature or other data
generated outside the processor package do not trigger special polling cycles on the
processor memory or SMBus interfaces to procure the required information.
2.5.2.6.1
DRAM Thermal and Power Optimization Capabilities
DRAM thermal and power optimization (also known as RAPL or “Running Average
Power Limit”) services provide a way for platform thermal management solutions to
program and access DRAM power, energy and temperature parameters. Memory
temperature information is typically used to regulate fan speeds, tune refresh rates and
throttle the memory subsystem as appropriate. Memory temperature data may be
derived from a variety of sources including on-die or on-board DIMM sensors, DRAM
activity information or a combination of the two. Though memory temperature data is a
byte long, range of actual temperature values are determined by the DIMM
specifications and operating range.
Note:
DRAM related PECI services described in this section apply only to the memory
connected to the specific processor PECI client in question and not the overall platform
memory in general. For estimating DRAM thermal information in closed loop throttling
mode, a dedicated SMBus is required between the CPU and the DIMMs. The processor
PCU requires access to the VR12 voltage regulator for reading average output current
information through the SVID bus for initial DRAM RAPL related power tuning.
Table 2-6 provides a summary of the DRAM power and thermal optimization capabilities
that can be accessed over PECI on the processor. The Index values referenced in
Table 2-6 are in decimal format.
Table 2-6 also provides information on alternate inband mechanisms to access similar
or equivalent information through register reads and writes where applicable. The user
should consult the Intel® 64 and IA-32 Architectures Software Developer’s Manual
(SDM) Volumes 1, 2, and 3 or Intel® Xeon® Processor E5 Product Family Datasheet

2.5.2.6.2
DRAM Thermal Estimation Configuration Data Read/Write
This feature is relevant only when activity-based DRAM temperature estimation
methods are being utilized and would apply to all the DIMMs on all the memory
channels. The write allows the PECI host to configure the ‘β’ and ‘θ’ variables in
Figure 2-12 for DRAM channel temperature filtering as per the equation below:
TN = β ∗ TN-1 + θ ∗ ΔEnergy
TN and TN-1 are the current and previous DRAM temperature estimates respectively in
degrees Celsius, ‘β’ is the DRAM temperature decay factor, ‘ΔEnergy’ is the energy
difference between the current and previous memory transactions as determined by
the processor power control unit and ‘θ’ is the DRAM energy-to-temperature translation
coefficient. The default value of ‘β’ is 0x3FF. ‘θ’ is defined by the equation:
θ = (1 - β) ∗ (Thermal Resistance) ∗ (Scaling Factor)
The ‘Thermal Resistance’ serves as a multiplier for translation of DRAM energy changes
to corresponding temperature changes and may be derived from actual platform
characterization data. The ‘Scaling Factor’ is used to convert memory transaction
information to energy units in Joules and can be derived from system/memory
configuration information. Refer to the Intel® 64 and IA-32 Architectures Software
Developer’s Manual (SDM) Volumes 1, 2, and 3 for methods to program and access
‘Scaling Factor’ information.

DRAM Rank Temperature Write
This feature allows the PECI host to program into the processor, the temperature for all
the ranks within a DIMM up to a maximum of four ranks as shown in Figure 2-13. The
DIMM index and Channel index are specified through the parameter field as shown in
Table 2-7. This write is relevant in platforms that do not have on-die or on-board
DIMM thermal sensors to provide memory temperature information or if the processor
does not have direct access to the DIMM thermal sensors. This temperature
information is used by the processor in conjunction with the activity-based DRAM
temperature estimations.

particular memory temperature source or temperature estimation method. For
platforms using DRAM thermal estimation, the PCU will provide the estimated
temperatures. Otherwise, the data represents the latest DIMM temperature provided
by the TSOD or on-board DIMM sensor and requires that CLTT (closed loop throttling
mode) be enabled and OLTT (open loop throttling mode) be disabled. Refer to Table 2-7
for channel index encodings.

DIMM Ambient Temperature Write / Read
This feature allows the PECI host to provide an ambient temperature reference to be
used by the processor for activity-based DRAM temperature estimation. This write is
used only when no DIMM temperature information is available from on-board or on-die
DIMM thermal sensors. It is also possible for the PECI host controller to read back the
DIMM ambient reference temperature.
Since the ambient temperature may vary over time within a system, it is recommended
that systems monitoring and updating the ambient temperature at a fast rate use the
‘maximum’ temperature value while those updating the ambient temperature at a slow
rate use an ‘average’ value. The ambient temperature assumes a single value for all
memory channel/DIMM locations and does not account for possible temperature
variations based on DIMM location.

systems using activity-based temperature estimations or alternatively return a ‘zero’
for systems using sensor-based temperatures.

Accumulated DRAM Energy Read
This feature allows the PECI host to read the DRAM energy consumed by all the DIMMs
within all the channels or all the DIMMs within just a specified channel. The parameter
field is used to specify the channel index. Units used are defined as per the Package
Power SKU Unit read described in Section 2.5.2.6.11. This information is tracked by a
32-bit counter that wraps around. The channel index in Figure 2-17 is specified as per
the index encoding described in Table 2-7. A channel index of 0x00FF is used to specify
the “all channels” case. While Intel requires reading the accumulated energy data at
least once every 16 seconds to ensure functional correctness, a more realistic polling
rate recommendation is once every 100 mS for better accuracy. This feature assumes a
200W memory capacity. In general, as the power capability decreases, so will the
minimum polling rate requirement.
When determining energy changes by subtracting energy values between successive
reads, Intel advocates using the 2’s complement method to account for counter wraparounds. Alternatively, adding all ‘F’s (‘0xFFFFFFFF’) to a negative result from the
subtraction will accomplish the same goal.

DRAM Power Info Read
This read returns the minimum, typical and maximum DRAM power settings and the
maximum time window over which the power can be sustained for the entire DRAM
domain and is inclusive of all the DIMMs within all the memory channels. Any power
values specified by the power limiting entity that is outside of the range specified
through these settings cannot be guaranteed. Since this data is 64 bits wide, PECI
facilitates access to this register by allowing two requests to read the lower 32 bits and
upper 32 bits separately as shown in Table 2-6. Power and time units for this read are
defined as per the Package Power SKU Unit settings described in Section 2.5.2.6.11.

The minimum DRAM power in Figure 2-18 corresponds to a minimum bandwidth
setting of the memory interface. It does ‘not’ correspond to a processor IDLE or
memory self-refresh state. The ‘time window’ in Figure 2-18 is representative of the
rate at which the power control unit (PCU) samples the DRAM energy consumption
information and reactively takes the necessary measures to meet the imposed power
limits. Programming too small a time window may not give the PCU enough time to
sample energy information and enforce the limit while too large a time window runs the
risk of the PCU not being able to monitor and take timely action on energy excursions.
While the DRAM power setting in Figure 2-18 provides a maximum value for the ‘time
window’ (typically a few seconds), the minimum value may be assumed to be
~100 mS.
The PCU programs the DRAM power settings described in Figure 2-18 when DRAM
characterization has been completed by the memory reference code (MRC) during boot
as indicated by the setting of the RST_CPL bit of the BIOS_RESET_CPL register. The
DRAM power settings will be programmed during boot independent of the ‘DRAM Power
Limit Enable’ bit setting. Please refer to the Intel® Xeon® Processor E5 Product Family
Datasheet Volume Two for information on memory energy estimation methods and
energy tuning options used by BIOS and other utilities for determining the range
specified in the DRAM power settings. In general, any tuning of the power settings is
done by polling the voltage regulators supplying the DIMMs.

DRAM Power Limit Data Write / Read
This feature allows the PECI host to program the power limit over a specified time or
control window for the entire DRAM domain covering all the DIMMs within all the
memory channels. Actual values are chosen based on DRAM power consumption
characteristics. The units for the DRAM Power Limit and Control Time Window are
determined as per the Package Power SKU Unit settings described in
Section 2.5.2.6.11. The DRAM Power Limit Enable bit in Figure 2-19 should be set to
activate this feature. Exact DRAM power limit values are largely determined by platform
memory configuration. As such, this feature is disabled by default and there are no
defaults associated with the DRAM power limit values. The PECI host may be used to
enable and initialize the power limit fields for the purposes of DRAM power budgeting.
Alternatively, this can also be accomplished through inband writes to the appropriate
registers. Both power limit enabling and initialization of power limit values can be done
in the same command cycle. All RAPL parameter values including the power limit value,
control time window, and enable bit will have to be specified correctly even if the intent
is to change just one parameter value when programming over PECI.

Intel® Xeon® Processor E5-1600/E5-2600/E5-4600 Product Families

The following conversion formula should be used for encoding or programming the
‘Control Time Window’ in bits [23:17].
Control Time Window (in seconds) = ([1 + 0.25 * ‘x’] * 2‘y’) * ‘z’ where
‘x’ = integer value of bits[23:22]
‘y’ = integer value of bits[21:17]
‘z’ = Package Power SKU Time Unit[19:16] (see Section 2.5.2.6.13 for details on
Package Power SKU Unit)
For example, using this formula, a control time value of 0x0A will correspond to a
‘1-second’ time window. A valid range for the value of the ‘Control Time Window’ in
Figure 2-19 that can be programmed into bits [23:17] is 250 mS - 40 seconds.
From a DRAM power management standpoint, all post-boot DRAM power management
activities (also referred to as ‘DRAM RAPL’ or ‘DRAM Running Average Power Limit’)
should be managed exclusively through a single interface like PECI or alternatively an
inband mechanism. If PECI is being used to manage DRAM power budgeting activities,
BIOS should lock out all subsequent inband DRAM power limiting accesses by setting
bit 31 of the DRAM_POWER_LIMIT MSR or DRAM_PLANE_POWER_LIMIT CSR to ‘1’.

DRAM Power Limit Performance Status Read
This service allows the PECI host to assess the performance impact of the currently
active DRAM power limiting modes. The read return data contains the sum of all the
time durations for which each of the DIMMs has been operating in a low power state.
This information is tracked by a 32-bit counter that wraps around. The unit for time is
determined as per the Package Power SKU Unit settings described in
Section 2.5.2.6.11. The DRAM performance data does not account for stalls on the
memory interface.
In general, for the purposes of DRAM RAPL, the DRAM power management entity
should use PECI accesses to DRAM energy and performance status in conjunction with
the power limiting feature to budget power between the various memory sub-systems
in the server system.

Package Power SKU Read
This read allows the PECI host to access the minimum, Thermal Design Power and
maximum power settings for the processor package SKU. It also returns the maximum
time interval or window over which the power can be sustained. If the power limiting
entity specifies a power limit value outside of the range specified through these
settings, power regulation cannot be guaranteed. Since this data is 64 bits wide, PECI
facilitates access to this register by allowing two requests to read the lower 32 bits and
upper 32 bits separately as shown in Table 2-8. Power units for this read are
determined as per the Package Power SKU Unit settings described in
Section 2.5.2.6.13.
‘Package Power SKU data’ is programmed by the PCU firmware during boot time based
on SKU dependent power-on default values set during manufacturing. The TDP
package power specified through bits [14:0] in Figure 2-28 is the maximum value of
the ‘Power Limit1’ field in Section 2.5.2.6.26 while the maximum package power in bits
[46:32] is the maximum value of the ‘Power Limit2’ field.
The minimum package power in bits [30:16] is applicable to both the ‘Power Limit1’ &
‘Power Limit2’ fields and corresponds to a mode when all the cores are operational and
in their lowest frequency mode. Attempts to program the power limit below the
minimum power value may not be effective since BIOS/OS, and not the PCU, controls
disabling of cores and core activity.
The ‘maximum time window’ in bits [54:48] is representative of the maximum rate at
which the power control unit (PCU) can sample the package energy consumption and
reactively take the necessary measures to meet the imposed power limits.
Programming too large a time window runs the risk of the PCU not being able to
monitor and take timely action on package energy excursions. On the other hand,
programming too small a time window may not give the PCU enough time to sample
energy information and enforce the limit. The minimum value of the ‘time window’ can
be obtained by reading bits [21:15] of the PWR_LIMIT_MISC_INFO CSR using the PECI
RdPCIConfigLocal() command.

“Wake on PECI” Mode Bit Write / Read
Setting the “Wake on PECI” mode bit enables successful completion of the
WrPCIConfigLocal(), RdPCIConfigLocal(), WrPCIConfig() and RdPCIConfig() PECI
commands by forcing a package ‘pop-up’ to the C2 state to service these commands if
the processor is in a low-power state. The exact power impact of such a ‘pop-up’ is
determined by the product SKU, the C-state from which the pop-up is initiated and the
negotiated PECI bit rate. A ‘reset’ or ‘clear’ of this bit or simply not setting the “Wake
on PECI” mode bit could result in a “timeout” response (completion code of 0x82) from
the processor indicating that the resources required to service the command are in a
low power state.
Alternatively, this mode bit can also be read to determine PECI behavior in package
states C3 or deeper.
2.5.2.6.16
Accumulated Run Time Read
This read returns the total time for which the processor has been executing with a
resolution of 1 mS per count. This is tracked by a 32-bit counter that rolls over on
reaching the maximum value. This counter activates and starts counting for the first
time at RESET_N de-assertion.
2.5.2.6.17
Package Temperature Read
This read returns the maximum processor die temperature in 16-bit PECI format. The
upper 16 bits of the response data are reserved. The PECI temperature data returned

Per Core DTS Temperature Read
This feature enables the PECI host to read the maximum value of the DTS temperature
for any specific core within the processor. Alternatively, this service can be used to read
the System Agent temperature. Temperature is returned in the same format as the
Package Temperature Read described in Section 2.5.2.6.17. Data is returned in relative
PECI temperature format.
Reads to a parameter value outside the supported range will return an error as
indicated by a completion code of 0x90. The supported range of parameter values can
vary depending on the number of cores within the processor. The temperature data
returned through this feature is the instantaneous value and not an averaged value. It
is updated once every 1 mS.
2.5.2.6.19
Temperature Target Read
The Temperature Target Read allows the PECI host to access the maximum processor
junction temperature (Tjmax) in degrees Celsius. This is also the default temperature
value at which the processor thermal control circuit activates. The Tjmax value may vary
from processor part to part to reflect manufacturing process variations. The
Temperature Target read also returns the processor TCONTROL value. TCONTROL is
returned in standard PECI temperature format and represents the threshold
temperature used by the thermal management system for fan speed control.

Package Thermal Status Read / Clear
The Thermal Status Read provides information on package level thermal status. Data
includes:
• Thermal Control Circuit (TCC) activation
• Bidirectional PROCHOT_N signal assertion
• Critical Temperature
Both status and sticky log bits are managed in this status word. All sticky log bits are
set upon a rising edge of the associated status bit and the log bits are cleared only by
Thermal Status reads or a processor reset. A read of the Thermal Status word always
includes a log bit clear mask that allows the host to clear any or all of the log bits that
it is interested in tracking.
A bit set to ‘0’ in the log bit clear mask will result in clearing the associated log bit. If a
mask bit is set to ‘0’ and that bit is not a legal mask, a failing completion code will be
returned. A bit set to ‘1’ is ignored and results in no change to any sticky log bits. For
example, to clear the TCC Activation Log bit and retain all other log bits, the Thermal
Status Read should send a mask of 0xFFFFFFFD.

Thermal Averaging Constant Write / Read
This feature allows the PECI host to control the window over which the estimated
processor PECI temperature is filtered. The host may configure this window as a power
of two. For example, programming a value of 5 results in a filtering window of 25 or 32
samples. The maximum programmable value is 8 or 256 samples. Programming a
value of zero would disable the PECI temperature averaging feature. The default value
of the thermal averaging constant is 4 which translates to an averaging window size of
24 or 16 samples. More details on the PECI temperature filtering function can be found
in Section 2.5.7.3.

Thermally Constrained Time Read
This features allows the PECI host to access the total time for which the processor has
been operating in a lowered power state due to TCC activation. The returned data
includes the time required to ramp back up to the original P-state target after TCC
activation expires. This timer does not include TCC activation as a result of an external
assertion of PROCHOT_N. This is tracked by a 32-bit counter with a resolution of 1mS
per count that rolls over or wraps around. On the processor PECI clients, the only logic
that can be thermally constrained is that supplied by VCC.
2.5.2.6.23
Current Limit Read
This read returns the current limit for the processor VCC power plane in 1/8A
increments. Actual current limit data is contained only in the lower 13 bits of the
response data. The default return value of 0x438 corresponds to a current limit value
of 135A.

Accumulated Energy Status Read
This service can return the value of the total energy consumed by the entire processor
package or just the logic supplied by the VCC power plane as specified through the
parameter field in Table 2-8. This information is tracked by a 32-bit counter that wraps
around and continues counting on reaching its limit. Energy units for this read are
determined as per the Package Power SKU Unit settings described in
Section 2.5.2.6.13.
While Intel requires reading the accumulated energy data at least once every 16
seconds to ensure functional correctness, a more realistic polling rate recommendation
is once every 100mS for better accuracy. This feature assumes a 150W processor. In
general, as the power capability decreases, so will the minimum polling rate
requirement.
When determining energy changes by subtracting energy values between successive
reads, Intel advocates using the 2’s complement method to account for counter wraparounds. Alternatively, adding all ‘F’s (‘0xFFFFFFFF’) to a negative result from the
subtraction will accomplish the same goal.

Power Limit for the VCC Power Plane Write / Read
This feature allows the PECI host to program the power limit over a specified time or
control window for the processor logic supplied by the VCC power plane. This typically
includes all the cores, home agent and last level cache. The processor does not support
power limiting on a per-core basis. Actual power limit values are chosen based on the
external VR (voltage regulator) capabilities. The units for the Power Limit and Control
Time Window are determined as per the Package Power SKU Unit settings described in
Section 2.5.2.6.13.
Since the exact VCC plane power limit value is a function of the platform VR, this
feature is not enabled by default and there are no default values associated with the
power limit value or the control time window. The Power Limit Enable bit in Figure 2-35
should be set to activate this feature. The Clamp Mode bit is also required to be set to
allow the cores to go into power states below what the operating system originally
requested. In general, this feature provides an improved mechanism for VR protection
Intel® Xeon® Processor E5-1600/E5-2600/E5-4600 Product Families
Datasheet Volume One

compared to the input PROCHOT_N signal assertion method. Both power limit enabling
and initialization of power limit values can be done in the same command cycle. Setting
a power limit for the VCC plane enables turbo modes for associated logic. External VR
protection is guaranteed during boot through operation at safe voltage and frequency.
All RAPL parameter values including the power limit value, control time window, clamp
mode and enable bit will have to be specified correctly even if the intent is to change
just one parameter value when programming over PECI.
The usefulness of the VCC power plane RAPL may be somewhat limited if the platform
has a fully compliant external voltage regulator. However, platforms using lower cost
voltage regulators may find this feature useful. The VCC RAPL value is generally
expected to be a static value after initialization and there may not be any use cases for
dynamic control of VCC plane power limit values during run time. BIOS may be ideally
used to read the VR (and associated heat sink) capabilities and program the PCU with
the power limit information during boot. No matter what the method is, Intel
recommends exclusive use of just one entity or interface, PECI for instance, to manage
VCC plane power limiting needs. If PECI is being used to manage VCC plane power
limiting activities, BIOS should lock out all subsequent inband VCC plane power limiting
accesses by setting bit 31 of the PP0_POWER_LIMIT MSR and CSR to ‘1’.
The same conversion formula used for DRAM Power Limiting (see Section 2.5.2.6.9)
should be applied for encoding or programming the ‘Control Time Window’ in bits
[23:17].

Package Power Limits For Multiple Turbo Modes
This feature allows the PECI host to program two power limit values to support multiple
turbo modes. The operating systems and drivers can balance the power budget using
these two limits. Two separate PECI requests are available to program the lower and
upper 32 bits of the power limit data shown in Figure 2-36. The units for the Power
Limit and Control Time Window are determined as per the Package Power SKU Unit
settings described in Section 2.5.2.6.13 while the valid range for power limit values are
determined by the Package Power SKU settings described in Section 2.5.2.6.14. Setting
the Clamp Mode bits is required to allow the cores to go into power states below what
the operating system originally requested. The Power Limit Enable bits should be set to
enable the power limiting function. Power limit values, enable and clamp mode bits can
all be set in the same command cycle. All RAPL parameter values including the power
limit value, control time window, clamp mode and enable bit will have to be specified
correctly even if the intent is to change just one parameter value when programming
over PECI.
Intel recommends exclusive use of just one entity or interface, PECI for instance, to
manage all processor package power limiting and budgeting needs. If PECI is being
used to manage package power limiting activities, BIOS should lock out all subsequent
inband package power limiting accesses by setting bit 31 of the
PACKAGE_POWER_LIMIT MSR and CSR to ‘1’. The ‘power limit 1’ is intended to limit
processor power consumption to any reasonable value below TDP and defaults to TDP.

Datasheet Volume One
‘Power Limit 1’ values may be impacted by the processor heat sinks and system air
flow. Processor ‘power limit 2’ can be used as appropriate to limit the current drawn by
the processor to prevent any external power supply unit issues. The ‘Power Limit 2’
should always be programmed to a value (typically 20%) higher than ‘Power Limit 1’
and has no default value associated with it.
Though this feature is disabled by default and external programming is required to
enable, initialize and control package power limit values and time windows, the
processor package will still turbo to TDP if ‘Power Limit 1’ is not enabled or initialized.
‘Control Time Window#1’ (Power_Limit_1_Time also known as Tau) values may be
programmed to be within a range of 250 mS-40 seconds. ‘Control Time Window#2’
(Power_Limit_2_Time) values should be in the range 3 mS-10 mS.
The same conversion formula used for the DRAM Power Limiting feature (see
Section 2.5.2.6.9) should be applied when programming the ‘Control Time Window’ bits
[23:17] for ‘power limit 1’ in Figure 2-36. The ‘Control Time Window’ for ‘power limit 2’
can be directly programmed into bits [55:49] in units of mS without the aid of any
conversion formulas.

Package Power Limit Performance Status Read
This service allows the PECI host to assess the performance impact of the currently
active power limiting modes. The read return data contains the total amount of time for
which the entire processor package has been operating in a power state that is lower
than what the operating system originally requested. This information is tracked by a
32-bit counter that wraps around. The unit for time is determined as per the Package
Power SKU Unit settings described in Section 2.5.2.6.13.

Efficient Performance Indicator Read
The Efficient Performance Indicator (EPI) Read provides an indication of the total
number of productive cycles. Specifically, these are the cycles when the processor is
engaged in any activity to retire instructions and as a result, consuming energy. Any
power management entity monitoring this indicator should sample it at least once
every 4 seconds to enable detection of wraparounds. Refer to the processor Intel® 64
and IA-32 Architectures Software Developer’s Manual (SDM) Volumes 1, 2, and 3, for
details on programming the Energy/Performance Bias (MSR_MISC_PWR_MGMT)
register to set the ‘Energy Efficiency’ policy of the processor.

ACPI P-T Notify Write & Read
This feature enables the processor turbo capability when used in conjunction with the
PECI package RAPL or power limit. When the BMC sets the package power limit to a
value below TDP, it also determines a new corresponding turbo frequency and notifies
the OS using the ‘ACPI Notify’ mechanism as supported by the _PPC or performance
present capabilities object. The BMC then notifies the processor PCU using the PECI
‘ACPI P-T Notify’ service by programming a new state that is one p-state below the
turbo frequency sent to the OS via the _PPC method.
When the OS requests a p-state higher than what is specified in bits [7:0] of the PECI
ACPI P-T Notify data field, the CPU will treat it as request for P0 or turbo. The PCU will
use the IA32_ENERGY_PERFORMANCE_BIAS register settings to determine the exact
extent of turbo. Any OS p-state request that is equal to or below what is specified in
the PECI ACPI P-T Notify will be granted as long as the RAPL power limit does not
impose a lower p-state. However, turbo will not be enabled in this instance even if there
is headroom between the processor energy consumption and the RAPL power limit.
This feature does not affect the Thermal Monitor behavior of the processor nor is it
impacted by the setting of the power limit clamp mode bit.

Caching Agent TOR Read
This feature allows the PECI host to read the Caching Agent (Cbo) Table of Requests
(TOR). This information is useful for debug in the event of a 3-strike timeout that
results in a processor IERR assertion. The 16-bit parameter field is used to specify the
Cbo index, TOR array index and bank number according to the following bit
assignments.
• Bits [1:0] - Bank Number - legal values from 0 to 2
• Bits [6:2] - TOR Array Index - legal values from 0 to 19
• Bits [10:7] - Cbo Index - legal values from 0 to 7
• Bit [11] - Read Mode - should be set to ‘0’ for TOR reads
• Bits [15:12] - Reserved
Bit[11] is the Read Mode bit and should be set to ‘0’ for TOR reads. The Read Mode bit
can alternatively be set to ‘1’ to read the ‘Core ID’ (with associated valid bit as shown in
Figure 2-40) that points to the first core that asserted the IERR. In this case bits [10:0]
of the parameter field are ignored. The ‘Core ID’ read may not return valid data until at
least 1 mS after the IERR assertion.

Thermal Margin Read
This service allows the PECI host to read the margin to the processor thermal profile or
load line. Thermal margin data is returned in the format shown in Figure 2-41 with a
sign bit, an integer part and a fractional part. A negative thermal margin value implies
that the processor is operating in violation of its thermal load line and may be indicative
of a need for more aggressive cooling mechanisms through a fan speed increase or
other means. This PECI service will continue to return valid margin values even when
the processor die temperature exceeds Tjmax.

RdIAMSR()
The RdIAMSR() PECI command provides read access to Model Specific Registers
(MSRs) defined in the processor’s Intel® Architecture (IA). MSR definitions may be
found in the Intel® 64 and IA-32 Architectures Software Developer’s Manual (SDM)
Volumes 1, 2, and 3. Refer to Table 2-11 for the exact listing of processor registers
accessible through this command.
2.5.2.7.1
Command Format
The RdIAMSR() format is as follows:
Write Length: 0x05
Read Length: 0x09 (qword)
Command: 0xb1
Description: Returns the data maintained in the processor IA MSR space as specified
by the ‘Processor ID’ and ‘MSR Address’ fields. The Read Length dictates the desired
data return size. This command supports only qword responses. All command
responses are prepended with a completion code that contains additional pass/fail
status information. Refer to Section 2.5.5.2 for details regarding completion codes.
2.5.2.7.2
Processor ID Enumeration
The ‘Processor ID’ field that is used to address the IA MSR space refers to a specific
logical processor within the CPU. The ‘Processor ID’ always refers to the same physical
location in the processor silicon regardless of configuration as shown in the example in
Figure 2-42. For example, if certain logical processors are disabled by BIOS, the
Processor ID mapping will not change. The total number of Processor IDs on a CPU is
product-specific.
‘Processor ID’ enumeration involves discovering the logical processors enabled within
the CPU package. This can be accomplished by reading the ‘Max Thread ID’ value
through the RdPkgConfig() command (Index 0, Parameter 3) described in
Section 2.5.2.6.12 and subsequently querying each of the supported processor
threads. Unavailable processor threads will return a completion code of 0x90.
Alternatively, this information may be obtained from the RESOLVED_CORES_MASK
register readable through the RdPCIConfigLocal() PECI command described in
Section 2.5.2.9 or other means. Bits [7:0] and [9:8] of this register contain the ‘Core
Mask’ and ‘Thread Mask’ information respectively. The ‘Thread Mask’ applies to all the
enabled cores within the processor package as indicated by the ‘Core Mask’. For
the processor PECI clients, the ‘Processor ID’ may take on values in the range 0
through 15.

RdIAMSR() Capabilities
The processor PECI client allows PECI RdIAMSR() access to the registers listed in
Table 2-11. These registers pertain to the processor core and uncore error banks
(machine check banks 0 through 19). Information on the exact number of accessible
banks for the processor device may be obtained by reading the IA32_MCG_CAP[7:0]
MSR (0x0179). This register may be alternatively read using a RDMSR BIOS
instruction. Please consult the Intel® 64 and IA-32 Architectures Software Developer’s
Manual (SDM) Volumes 1, 2, and 3 for more information on the exact number of cores
supported by a particular processor SKU. Any attempt to read processor MSRs that are
not accessible over PECI or simply not implemented will result in a completion code of
0x90.
PECI access to these registers is expected only when in-band access mechanisms are
not available.

Notes:
1.
The IA32_MC0_MISC register details will be available upon implementation in a future processor stepping.
2.
The MCi_ADDR and MCi_MISC registers for machine check banks 2 & 4 are not implemented on the processors. The MCi_CTL
register for machine check bank 2 is also not implemented.
3.
The PECI host must determine the total number of machine check banks and the validity of the MCi_ADDR and MCi_MISC
register contents prior to issuing a read to the machine check bank similar to standard machine check architecture
enumeration and accesses.
4.
The information presented in Table 2-11 is applicable to the processor only. No association between bank numbers and logical
functions should be assumed for any other processor devices (past, present or future) based on the information presented in
Table 2-11.
5.
The processor machine check banks 4 through 19 reside in the processor uncore and hence will return the same value
independent of the processor ID used to access these banks.
6.
The IA32_MCG_STATUS, IA32_MCG_CONTAIN and IA32_MCG_CAP are located in the uncore and will return the same value
independent of the processor ID used to access them.
7.
The processor machine check banks 0 through 3 are core-specific. Since the processor ID is thread-specific and not corespecific, machine check banks 0 through 3 will return the same value for a particular core independent of the thread
referenced by the processor ID.
8.
PECI accesses to the machine check banks may not be possible in the event of a core hang. A warm reset of the processor
may be required to read any sticky machine check banks.
9.
Valid processor ID values may be obtained by using the enumeration methods described in Section 2.5.2.7.2.
10. Reads to a machine check bank within a core or thread that is disabled will return all zeroes with a completion code of 0x90.
11. For SKUs where Intel QPI is disabled or absent, reads to the corresponding machine check banks will return all zeros with a
completion code of 0x40.

RdPCIConfig()
The RdPCIConfig() command provides sideband read access to the PCI configuration
space maintained in downstream devices external to the processor. PECI originators
may conduct a device/function/register enumeration sweep of this space by issuing
reads in the same manner that the BIOS would. A response of all 1’s may indicate that
the device/function/register is unimplemented even with a ‘passing’ completion code.
Alternatively, reads to unimplemented registers may return a completion code of 0x90
indicating an invalid request. Responses will follow normal PCI protocol.
PCI configuration addresses are constructed as shown in Figure 2-44. Under normal inband procedures, the Bus number would be used to direct a read or write to the proper
device. Actual PCI bus numbers for all PCI devices including the PCH are programmable
by BIOS. The bus number for PCH devices may be obtained by reading the CPUBUSNO
CSR. Refer to the Intel® Xeon® Processor E5 Product Family Datasheet Volume Two
document for details on this register.

RdPCIConfigLocal()
The RdPCIConfigLocal() command provides sideband read access to the PCI
configuration space that resides within the processor. This includes all processor IIO
and uncore registers within the PCI configuration space as described in the Intel®
Xeon® Processor E5 Product Family Datasheet Volume Two document.
PECI originators may conduct a device/function enumeration sweep of this space by
issuing reads in the same manner that the BIOS would. A response of all 1’s may
indicate that the device/function/register is unimplemented even with a ‘passing’
completion code. Alternatively, reads to unimplemented or hidden registers may return
a completion code of 0x90 indicating an invalid request. It is also possible that reads to
function 0 of non-existent IIO devices issued prior to BIOS POST may return all ‘0’s
with a passing completion code. PECI originators can access this space even prior to
BIOS enumeration of the system buses. There is no read restriction on accesses to
locked registers.
PCI configuration addresses are constructed as shown in Figure 2-46. Under normal inband procedures, the Bus number would be used to direct a read or write to the proper
device. PECI reads to the processor IIO devices should specify a bus number of ‘0000’
and reads to the rest of the processor uncore should specify a bus number of ‘0001’ for
bits [23:20] in Figure 2-46. Any request made with a bad Bus number is ignored and
the client will respond with all ‘0’s and a ‘passing’ completion code.

WrPCIConfigLocal()
The WrPCIConfigLocal() command provides sideband write access to the PCI
configuration space that resides within the processor. PECI originators can access this
space even before BIOS enumeration of the system buses. The exact listing of
supported devices and functions for writes using this command on the processor is
defined in Table 2-19. The write accesses to registers that are locked will not take effect
but will still return a completion code of 0x40. However, write accesses to registers that
are hidden will return a completion code of 0x90.
Because a WrPCIConfigLocal() command results in an update to potentially critical
registers inside the processor, it includes an Assured Write FCS (AW FCS) byte as
part of the write data payload. In the event that the AW FCS mismatches with the
client-calculated FCS, the client will abort the write and will always respond with a bad
write FCS.
PCI Configuration addresses are constructed as shown in Figure 2-46. The write
command is subject to the same address configuration rules as defined in
Section 2.5.2.9. PCI configuration writes may be issued in byte, word or dword
granularity.
2.5.2.10.1

Description: Writes the data sent to the requested register address. Write Length
dictates the desired write granularity. The command always returns a completion code

WrPCIConfigLocal() Capabilities
On the processor PECI clients, the PECI WrPCIConfigLocal() command provides a
method for programming certain integrated memory controller and IIO functions as
described in Table 2-15. Refer to the Intel® Xeon® Processor E5 Product Family
Datasheet Volume Two for more details on specific register definitions. It also enables
writing to processor REUT (Robust Electrical Unified Test) registers associated with the

Client Management
2.5.3.1
Power-up Sequencing
The PECI client will not be available when the PWRGOOD signal is de-asserted. Any
transactions on the bus during this time will be completely ignored, and the host will
read the response from the client as all zeroes. PECI client initialization is completed
approximately 100 µS after the PWRGOOD assertion. This is represented by the start of
the PECI Client “Data Not Ready” (DNR) phase in Figure 2-49. While in this phase, the
PECI client will respond normally to the Ping() and GetDIB() commands and return the
highest processor die temperature of 0x0000 to the GetTemp() command. All other
commands will get a ‘Response Timeout’ completion in the DNR phase as shown in
Table 2-16. All PECI services with the exception of core MSR space accesses become
available ~500 µS after RESET_N de-assertion as shown in Figure 2-49. PECI will be
fully functional with all services including core accesses being available when the core
comes out of reset upon completion of the RESET microcode execution.
In the event of the occurrence of a fatal or catastrophic error, all PECI services with the
exception of core MSR space accesses will be available during the DNR phase to
facilitate debug through configuration space accesses.

Device Discovery
The PECI client is available on all processors. The presence of a PECI enabled processor
in a CPU socket can be confirmed by using the Ping() command described in
Section 2.5.2.1. Positive identification of the PECI revision number can be achieved by
issuing the GetDIB() command. The revision number acts as a reference to the PECI
specification document applicable to the processor client definition. Please refer to
Section 2.5.2.2 for details on GetDIB response formatting.
2.5.3.3
Client Addressing
The PECI client assumes a default address of 0x30. The PECI client address for the
processor is configured through the settings of the SOCKET_ID[1:0] signals. Each
processor socket in the system requires that the two SOCKET_ID signals be configured
to a different PECI addresses. Strapping the SOCKET_ID[1:0] pins results in the client
addresses shown in Table 2-17. These package strap(s) are evaluated at the assertion
of PWRGOOD (as depicted in Figure 2-49). Refer to the appropriate Platform Design
Guide (PDG) for recommended resistor values for establishing non-default SOCKET_ID
settings.
70
Intel® Xeon® Processor E5-1600/E5-2600/E5-4600 Product Families
Datasheet Volume One
The client address may not be changed after PWRGOOD assertion, until the next power
cycle on the processor. Removal of a processor from its socket or tri-stating a processor
will have no impact to the remaining non-tri-stated PECI client addresses. Since each
socket in the system should have a unique PECI address, the SOCKET_ID strapping is
required to be unique for each socket.

C-states
The processor PECI client may be fully functional in most core and package C-states.
• The Ping(), GetDIB(), GetTemp(), RdPkgConfig() and WrPkgConfig() commands
have no measurable impact on CPU power in any of the core or package C-states.
• The RdIAMSR() command will complete normally unless the targeted core is in a Cstate that is C3 or deeper. The PECI client will respond with a completion code of
0x82 (see Table 2-22 for definition) for RdIAMSR() accesses in core C-states that
are C3 or deeper.
• The RdPCIConfigLocal(), WrPCIConfigLocal(), and RdPCIConfig() commands will
not impact the core C-states but may have a measurable impact on the package Cstate. The PECI client will successfully return data without impacting package Cstate if the resources needed to service the command are not in a low power state.
— If the resources required to service the command are in a low power state, the
PECI client will respond with a completion code of 0x82 (see Table 2-22 for
definition). If this is the case, setting the “Wake on PECI” mode bit as described
in Section 2.5.2.6 can cause a package ‘pop-up’ to the C2 state and enable
successful completion of the command. The exact power impact of a pop-up to
C2 will vary by product SKU, the C-state from which the pop-up is initiated and
the negotiated PECI bit rate.

2.5.3.5
S-states
The processor PECI client is always guaranteed to be operational in the S0 sleep state.
• The Ping(), GetDIB(), GetTemp(), RdPkgConfig(), WrPkgConfig(),
RdPCIConfigLocal() and WrPCIConfigLocal() will be fully operational in S0 and S1.
Responses in S3 or deeper states are dependent on POWERGOOD assertion status.
• The RdPCIConfig() and RdIAMSR() responses are guaranteed in S0 only. Behavior
in S1 or deeper states is indeterminate.
• PECI behavior is indeterminate in the S3, S4 and S5 states and responses to PECI
originator requests when the PECI client is in these states cannot be guaranteed.
2.5.3.6
Processor Reset
The processor PECI client is fully reset on all RESET_N assertions. Upon deassertion of
RESET_N where power is maintained to the processor (otherwise known as a ‘warm
reset’), the following are true:
• The PECI client assumes a bus Idle state.
• The Thermal Filtering Constant is retained.
• PECI SOCKET_ID is retained.
• GetTemp() reading resets to 0x0000.
• Any transaction in progress is aborted by the client (as measured by the client no
longer participating in the response).
• The processor client is otherwise reset to a default configuration.
The assertion of the CPU_ONLY_RESET signal does not reset the processor PECI client.
As such, it will have no impact on the basic PECI commands, namely the Ping(),
GetTemp() and GetDIB(). However, it is likely that other PECI commands that utilize
processor resources being reset will receive a ‘resource unavailable’ response till the
reset sequence is completed.
2.5.3.7
System Service Processor (SSP) Mode Support
Sockets in SSP mode have limited PECI command support. Only the following PECI
commands will be supported while in SSP mode. Other PECI commands are not
guaranteed to complete in this mode.
• Ping
• RdPCIConfigLocal
• WrPCIConfigLocal (all uncore and IIO CSRs within the processor PCI configuration
space will be accessible)
• RdPkgConfig (Index 0 only)
Sockets remain in SSP mode until the "Go" handshake is received. This is applicable to
the following SSP modes.
2.5.3.7.1
BMC INIT Mode
The BMC INIT boot mode is used to provide a quick and efficient means to transfer
responsibility for uncore configuration to a service processor like the BMC. In this
mode, the socket performs a minimal amount of internal configuration and then waits
for the BMC or service processor to complete the initialization.
72
Intel® Xeon® Processor E5-1600/E5-2600/E5-4600 Product Families
Datasheet Volume One
2.5.3.7.2
Link Init Mode
In cases where the socket is not one Intel QPI hop away from the Firmware Agent
socket, or a working link to the Firmware Agent socket cannot be resolved, the socket
is placed in Link Init mode. The socket performs a minimal amount of internal
configuration and waits for complete configuration by BIOS.
2.5.3.8
Processor Error Handling
Availability of PECI services may be affected by the processor PECI client error status.
Server manageability requirements place a strong emphasis on continued availability of
PECI services to facilitate logging and debug of the error condition.
• Most processor PECI client services are available in the event of a CAT_ERR_N
assertion though they cannot be guaranteed.
• The Ping(), GetDIB(), GetTemp(), RdPkgConfig() and WrPkgConfig() commands will
be serviced if the source of the CAT_ERR_N assertion is not in the processor power
control unit hardware, firmware or associated register logic. Additionally, the
RdPCIConfigLocal() and WrPCIConfigLocal() commands may also be serviced in this
case.
• It is recommended that the PECI originator read Index 0/Parameter 5 using the
RdPkgConfig() command to debug the CAT_ERR_N assertion.
— The PECI client will return the 0x91 completion code if the CAT_ERR_N
assertion is caused by the PCU hardware, firmware or associated logic errors.
In such an event, only the Ping(), GetTemp() and GetDIB() PECI commands
may be serviced. All other processor PECI services will be unavailable and
further debug of the processor error status will not be possible.
— If the PECI client returns a passing completion code, the originator should use
the response data to determine the cause of the CAT_ERR_N assertion. In such
an event, it is also recommended that the PECI originator determine the exact
suite of available PECI client services by issuing each of the PECI commands.
The processor will issue ‘timeout’ responses for those services that may not be
available.
— If the PECI client continues to return the 0x81 completion code in response to
multiple retries of the RdPkgConfig() command, no PECI services, with the
exception of the Ping(), GetTemp() and GetDIB(), will be guaranteed.
• The RdIAMSR() command may be serviced during a CAT_ERR_N assertion though it
cannot be guaranteed.
2.5.3.9
Originator Retry and Timeout Policy
The PECI originator may need to retry a command if the processor PECI client responds
with a ‘response timeout’ completion code or a bad Read FCS. In each instance, the
processor PECI client may have started the operation but not completed it yet. When
the 'retry' bit is set, the PECI client will ignore a new request if it exactly matches a
previous valid request.
The processor PECI client will not clear the semaphore that was acquired to service the
request until the originator sends the ‘retry’ request in a timely fashion to successfully
retrieve the response data. In the absence of any automatic timeouts, this could tie up
shared resources and result in artificial bandwidth conflicts.

2.5.3.10
Enumerating PECI Client Capabilities
The PECI host originator should be designed to support all optional but desirable
features from all processors of interest. Each feature has a discovery method and
response code that indicates availability on the destination PECI client.
The first step in the enumeration process would be for the PECI host to confirm the
Revision Number through the use of the GetDIB() command. The revision number
returned by the PECI client processor always maps to the revision number of the PECI
specification that it is designed to. The Minor Revision Number as described in Table 2-2
may be used to identify the subset of PECI commands that the processor in question
supports for any major PECI revision.
The next step in the enumeration process is to utilize the desired command suite in a
real execution context. If the Write FCS response is an Abort FCS or if the data
returned includes an “Unknown/Invalid/Illegal Request” completion code (0x90), then
the command is unsupported.
Enumerating known commands without real, execution context data, or attempting
undefined commands, is dangerous because a write command could result in
unexpected behavior if the data is not properly formatted. Methods for enumerating
write commands using carefully constructed and innocuous data are possible, but are
not guaranteed by the PECI client definition.
This enumeration procedure is not robust enough to detect differences in bit definitions
or data interpretation in the message payload or client response. Instead, it is only
designed to enumerate discrete features.
2.5.4
Multi-Domain Commands
The processor does not support multiple domains, but it is possible that future products
will, and the following tables are included as a reference for domain-specific definitions.

Client Responses
2.5.5.1
Abort FCS
The Client responds with an Abort FCS under the following conditions:
• The decoded command is not understood or not supported on this processor (this
includes good command codes with bad Read Length or Write Length bytes).
• Assured Write FCS (AW FCS) failure. Under most circumstances, an Assured Write
failure will appear as a bad FCS. However, when an originator issues a poorly
formatted command with a miscalculated AW FCS, the client will intentionally abort
the FCS in order to guarantee originator notification.
2.5.5.2
Completion Codes
Some PECI commands respond with a completion code byte. These codes are designed
to communicate the pass/fail status of the command and may also provide more
detailed information regarding the class of pass or fail. For all commands listed in
Section 2.5.2 that support completion codes, the definition in the following table
applies. Throughout this document, a completion code reference may be abbreviated
with ‘CC’.
An originator that is decoding these commands can apply a simple mask as shown in
Table 2-21 to determine a pass or fail. Bit 7 is always set on a command that did not
complete successfully and is cleared on a passing command.

The codes explicitly defined in Table 2-22 may be useful in PECI originator response
algorithms. Reserved or undefined codes may also be generated by a PECI client
device, and the originating agent must be capable of tolerating any code. The Pass/Fail
mask defined in Table 2-21 applies to all codes, and general response policies may be
based on this information. Refer to Section 2.5.6 for originator response policies and
recommendations.

2.5.6
Originator Responses
The simplest policy that an originator may employ in response to receipt of a failing
completion code is to retry the request. However, certain completion codes or FCS
responses are indicative of an error in command encoding and a retry will not result in
a different response from the client. Furthermore, the message originator must have a
response policy in the event of successive failure responses. Refer to Table 2-22 for
originator response guidelines.
Refer to the definition of each command in Section 2.5.2 for a specific definition of
possible command codes or FCS responses for a given command. The following
response policy definition is generic, and more advanced response policies may be
employed at the discretion of the originator developer.

Interpretation
The resolution of the processor’s Digital Thermal Sensor (DTS) is approximately 1°C,
which can be confirmed by a RDMSR from the IA32_THERM_STATUS MSR where it is
architecturally defined. The MSR read will return only bits [13:6] of the PECI
temperature sensor data defined in Figure 2-50. PECI temperatures are sent through a
configurable low-pass filter prior to delivery in the GetTemp() response data. The
output of this filter produces temperatures at the full 1/64°C resolution even though
the DTS itself is not this accurate.

Temperature readings from the processor are always negative in a 2’s complement
format, and imply an offset from the processor Tjmax (PECI = 0). For example, if the
processor Tjmax is 100°C, a PECI thermal reading of -10 implies that the processor is
running at approximately 10°C below Tjmax or at 90°C. PECI temperature readings are
not reliable at temperatures above Tjmax since the processor is outside its operating
range and hence, PECI temperature readings are never positive.
The changes in PECI data counts are approximately linear in relation to changes in
temperature in degrees centigrade. A change of ‘1’ in the PECI count represents
roughly a temperature change of 1 degree centigrade. This linearity is approximate and
cannot be guaranteed over the entire range of PECI temperatures, especially as the
offset from the maximum PECI temperature (zero) increases.
2.5.7.3
Temperature Filtering
The processor digital thermal sensor (DTS) provides an improved capability to monitor
device hot spots, which inherently leads to more varying temperature readings over
short time intervals. Coupled with the fact that typical fan speed controllers may only
read temperatures at 4Hz, it is necessary for the thermal readings to reflect thermal
trends and not instantaneous readings. Therefore, PECI supports a configurable lowpass temperature filtering function that is expressed by the equation:
TN = (1-α) * TN-1 + α * TSAMPLE
where TN and TN-1 are the current and previous averaged PECI temperature values
respectively, TSAMPLE is the current PECI temperature sample value and the variable
‘α’ = 1/2X, where ‘X’ is the ‘Thermal Averaging Constant’ that is programmable as
described in Section 2.5.2.6.21.

Intel® Virtualization Technology (Intel® VT)
Intel® Virtualization Technology (Intel® VT) makes a single system appear as multiple
independent systems to software. This allows multiple, independent operating systems
to run simultaneously on a single system. Intel VT comprises technology components
to support virtualization of platforms based on Intel architecture microprocessors and
chipsets.
• Intel® Virtualization Technology (Intel® VT) for Intel® 64 and IA-32
Intel® Architecture (Intel® VT-x) adds hardware support in the processor to
improve the virtualization performance and robustness. Intel VT-x specifications
and functional descriptions are included in the Intel® 64 and IA-32 Architectures
Software Developer’s Manual, Volume 3B and is available at http://www.intel.com/
products/processor/manuals/index.htm
• Intel® Virtualization Technology (Intel® VT) for Directed I/O
(Intel® VT-d) adds processor and uncore implementations to support and
improve I/O virtualization performance and robustness. The Intel VT-d spec and
other Intel VT documents can be referenced at http://www.intel.com/technology/
virtualization/index.htm.
3.1.1
Intel VT-x Objectives
Intel VT-x provides hardware acceleration for virtualization of IA platforms. Virtual
Machine Monitor (VMM) can use Intel VT-x features to provide improved reliable
virtualized platform. By using Intel VT-x, a VMM is:
• Robust: VMMs no longer need to use para-virtualization or binary translation. This
means that they will be able to run off-the-shelf OS’s and applications without any
special steps.
• Enhanced: Intel VT enables VMMs to run 64-bit guest operating systems on IA x86
processors.
• More reliable: Due to the hardware support, VMMs can now be smaller, less
complex, and more efficient. This improves reliability and availability and reduces
the potential for software conflicts.
• More secure: The use of hardware transitions in the VMM strengthens the isolation
of VMs and further prevents corruption of one VM from affecting others on the
same system.

3.1.2
Intel VT-x Features
The processor core supports the following Intel VT-x features:
• Extended Page Tables (EPT)
— hardware assisted page table virtualization
— eliminates VM exits from guest OS to the VMM for shadow page-table
maintenance
• Virtual Processor IDs (VPID)
— Ability to assign a VM ID to tag processor core hardware structures (for
example, TLBs)
— This avoids flushes on VM transitions to give a lower-cost VM transition time
and an overall reduction in virtualization overhead.
• Guest Preemption Timer
— Mechanism for a VMM to preempt the execution of a guest OS after an amount
of time specified by the VMM. The VMM sets a timer value before entering a
guest
— The feature aids VMM developers in flexibility and Quality of Service (QoS)
guarantees
• Descriptor-Table Exiting
— Descriptor-table exiting allows a VMM to protect a guest OS from internal
(malicious software based) attack by preventing relocation of key system data
structures like IDT (interrupt descriptor table), GDT (global descriptor table),
LDT (local descriptor table), and TSS (task segment selector).
— A VMM using this feature can intercept (by a VM exit) attempts to relocate
these data structures and prevent them from being tampered by malicious
software.
• Pause Loop Exiting (PLE)
— PLE aims to improve virtualization performance and enhance the scaling of
virtual machines with multiple virtual processors
— PLE attempts to detect lock-holder preemption in a VM and helps the VMM to
make better scheduling decisions
3.1.3
Intel VT-d Objectives
The key Intel VT-d objectives are domain-based isolation and hardware-based
virtualization. A domain can be abstractly defined as an isolated environment in a
platform to which a subset of host physical memory is allocated. Virtualization allows
for the creation of one or more partitions on a single system. This could be multiple
partitions in the same operating system, or there can be multiple operating system
instances running on the same system – offering benefits such as system
consolidation, legacy migration, activity partitioning or security.
3.1.3.1
Intel VT-d Features Supported
The processor supports the following Intel VT-d features:
• Root entry, context entry, and default context
• Support for 4-K page sizes only
• Support for register-based fault recording only (for single entry only) and support
for MSI interrupts for faults

• Interrupt remapping
3.1.4
Intel Virtualization Technology Processor Extensions
The processor supports the following Intel VT Processor Extensions features:
• Large Intel VT-d Pages
— Adds 2 MB and 1 GB page sizes to Intel VT-d implementations
— Matches current support for Extended Page Tables (EPT)
— Ability to share CPU's EPT page-table (with super-pages) with Intel VT-d
— Benefits:
• Less memory foot-print for I/O page-tables when using super-pages
• Potential for improved performance - Due to shorter page-walks, allows
hardware optimization for IOTLB
• Transition latency reductions expected to improve virtualization performance
without the need for VMM enabling. This reduces the VMM overheads further and
increase virtualization performance.

Security Technologies
3.2.1
Intel® Trusted Execution Technology
Intel® Trusted Execution Technology (Intel® TXT) defines platform-level
enhancements that provide the building blocks for creating trusted platforms.
The Intel TXT platform helps to provide the authenticity of the controlling environment
such that those wishing to rely on the platform can make an appropriate trust decision.
The Intel TXT platform determines the identity of the controlling environment by
accurately measuring and verifying the controlling software.
Another aspect of the trust decision is the ability of the platform to resist attempts to
change the controlling environment. The Intel TXT platform will resist attempts by
software processes to change the controlling environment or bypass the bounds set by
the controlling environment.
Intel TXT is a set of extensions designed to provide a measured and controlled launch
of system software that will then establish a protected environment for itself and any
additional software that it may execute.

Technologies
These extensions enhance two areas:
• The launching of the Measured Launched Environment (MLE).
• The protection of the MLE from potential corruption.
The enhanced platform provides these launch and control interfaces using Safer Mode
Extensions (SMX).
The SMX interface includes the following functions:
• Measured/Verified launch of the MLE.
• Mechanisms to ensure the above measurement is protected and stored in a secure
location.
• Protection mechanisms that allow the MLE to control attempts to modify itself.

Intel Trusted Execution Technology – Server Extensions
• Software binary compatible with Intel Trusted Execution Technology Server
Extensions
• Provides measurement of runtime firmware, including SMM
• Enables run-time firmware in trusted session: BIOS and SSP
• Covers support for existing and expected future Server RAS features
• Only requires portions of BIOS to be trusted, for example, Option ROMs need not
be trusted
• Supports S3 State without teardown: Since BIOS is part of the trust chain
3.2.3
Intel® Advanced Encryption Standard Instructions
(Intel® AES-NI)
These instructions enable fast and secure data encryption and decryption, using the
Intel® AES New Instructions (Intel® AES-NI), which is defined by FIPS Publication
number 197. Since Intel AES-NI is the dominant block cipher, and it is deployed in
various protocols, the new instructions will be valuable for a wide range of applications.
The architecture consists of six instructions that offer full hardware support for Intel
AES-NI. Four instructions support the Intel AES-NI encryption and decryption, and the
other two instructions support the Intel AES-NI key expansion. Together, they offer a
significant increase in performance compared to pure software implementations.
The Intel AES-NI instructions have the flexibility to support all three standard Intel
AES-NI key lengths, all standard modes of operation, and even some nonstandard or
future variants.
Beyond improving performance, the Intel AES-NI instructions provide important
security benefits. Since the instructions run in data-independent time and do not use
lookup tables, they help in eliminating the major timing and cache-based attacks that
threaten table-based software implementations of Intel AES-NI. In addition, these
instructions make AES simple to implement, with reduced code size. This helps
reducing the risk of inadvertent introduction of security flaws, such as difficult-todetect side channel leaks.

Execute Disable Bit
Intel's Execute Disable Bit functionality can help prevent certain classes of malicious
buffer overflow attacks when combined with a supporting operating system.
• Allows the processor to classify areas in memory by where application code can
execute and where it cannot.
• When a malicious worm attempts to insert code in the buffer, the processor
disables code execution, preventing damage and worm propagation.
3.3
Intel® Hyper-Threading Technology
The processor supports Intel® Hyper-Threading Technology (Intel® HT Technology),
which allows an execution core to function as two logical processors. While some
execution resources such as caches, execution units, and buses are shared, each
logical processor has its own architectural state with its own set of general-purpose
registers and control registers. This feature must be enabled via the BIOS and requires
operating system support. For more information on Intel Hyper-Threading Technology,
see http://www.intel.com/products/ht/hyperthreading_more.htm.
3.4
Intel® Turbo Boost Technology
Intel® Turbo Boost Technology is a feature that allows the processor to
opportunistically and automatically run faster than its rated operating frequency if it is
operating below power, temperature, and current limits. The result is increased
performance in multi-threaded and single threaded workloads. It should be enabled in
the BIOS for the processor to operate with maximum performance.
3.4.1
Intel® Turbo Boost Operating Frequency
The processor’s rated frequency assumes that all execution cores are running an
application at the thermal design power (TDP). However, under typical operation, not
all cores are active. Therefore most applications are consuming less than the TDP at the
rated frequency. To take advantage of the available TDP headroom, the active cores can
increase their operating frequency.
To determine the highest performance frequency amongst active cores, the processor
takes the following into consideration:
• The number of cores operating in the C0 state.
• The estimated current consumption.
• The estimated power consumption.
• The die temperature.
Any of these factors can affect the maximum frequency for a given workload. If the
power, current, or thermal limit is reached, the processor will automatically reduce the
frequency to stay with its TDP limit.
Note:
Intel Turbo Boost Technology is only active if the operating system is requesting the P0
state. For more information on P-states and C-states refer to Section 4, “Power
Management”.

Enhanced Intel SpeedStep® Technology
The processor supports Enhanced Intel SpeedStep® Technology as an advanced means
of enabling very high performance while also meeting the power-conservation needs of
the platform.
Enhanced Intel SpeedStep Technology builds upon that architecture using design
strategies that include the following:
• Separation between Voltage and Frequency Changes. By stepping voltage up
and down in small increments separately from frequency changes, the processor is
able to reduce periods of system unavailability (which occur during frequency
change). Thus, the system is able to transition between voltage and frequency
states more often, providing improved power/performance balance.
• Clock Partitioning and Recovery. The bus clock continues running during state
transition, even when the core clock and Phase-Locked Loop are stopped, which
allows logic to remain active. The core clock is also able to restart more quickly
under Enhanced Intel SpeedStep Technology.
For additional information on Enhanced Intel SpeedStep Technology see Section 4.2.1.

Intel® Intelligent Power Technology
Intel® Intelligent Power Technology conserves power while delivering advanced powermanagement capabilities at the rack, group, and data center level. Providing the
highest system-level performance per watt with “Automated Low Power States” and
“Integrated Power Gates”. Improvements to this processor generation are:
• Intel Network Power Management Technology
• Intel Power Tuning Technology

3.7
Intel® Advanced Vector Extensions (Intel® AVX)
Intel® Advanced Vector Extensions (Intel® AVX) is a new 256-bit vector SIMD
extension of Intel Architecture. The introduction of Intel AVX starts with the 2nd
Generation Intel(r) Core(TM) Processor Family. Intel AVX accelerates the trend of
parallel computation in general purpose applications like image, video, and audio
processing, engineering applications such as 3D modeling and analysis, scientific
simulation, and financial analysts.
Intel AVX is a comprehensive ISA extension of the Intel® 64 Architecture. The main
elements of Intel AVX are:
• Support for wider vector data (up to 256-bit) for floating-point computation.
• Efficient instruction encoding scheme that supports 3 operand syntax and
headroom for future extensions.
• Flexibility in programming environment, ranging from branch handling to relaxed
memory alignment requirements.
• New data manipulation and arithmetic compute primitives, including broadcast,
permute, fused-multiply-add, and so forth.
84
Intel® Xeon® Processor E5-1600/E5-2600/E5-4600 Product Families
Datasheet Volume One
Technologies
The key advantages of Intel AVX are:
• Performance - Intel AVX can accelerate application performance via data
parallelism and scalable hardware infrastructure across existing and new
application domains:
— 256-bit vector data sets can be processed up to twice the throughput of 128-bit
data sets.
— Application performance can scale up with number of hardware threads and
number of cores.
— Application domain can scale out with advanced platform interconnect fabrics,
such as Intel QPI.
• Power Efficiency - Intel AVX is extremely power efficient. Incremental power is
insignificant when the instructions are unused or scarcely used. Combined with the
high performance that it can deliver, applications that lend themselves heavily to
using Intel AVX can be much more energy efficient and realize a higher
performance-per-watt.
• Extensibility - Intel AVX has built-in extensibility for the future vector extensions:
— OS context management for vector-widths beyond 256 bits is streamlined.
— Efficient instruction encoding allows unlimited functional enhancements:
• Vector width support beyond 256 bits
• 256-bit Vector Integer processing
• Additional computational and/or data manipulation primitives.
• Compatibility - Intel AVX is backward compatible with previous ISA extensions
including Intel® SSE4:
— Existing Intel SSE applications/library can:
• Run unmodified and benefit from processor enhancements
• Recompile existing Intel SSE intrinsic using compilers that generate Intel
AVX code
• Inter-operate with library ported to Intel AVX
— Applications compiled with Intel AVX can inter-operate with existing Intel SSE
libraries.

Power Management
4.2
Processor Core/Package Power Management
While executing code, Enhanced Intel SpeedStep Technology optimizes the processor’s
frequency and core voltage based on workload. Each frequency and voltage operating
point is defined by ACPI as a P-state. When the processor is not executing code, it is
idle. A low-power idle state is defined by ACPI as a C-state. In general, lower power
C-states have longer entry and exit latencies.
4.2.1
Enhanced Intel SpeedStep® Technology
The following are the key features of Enhanced Intel SpeedStep Technology:
• Multiple frequency and voltage points for optimal performance and power
efficiency. These operating points are known as P-states.
• Frequency selection is software controlled by writing to processor MSRs. The
voltage is optimized based on temperature, leakage, power delivery loadline and
dynamic capacitance.
— If the target frequency is higher than the current frequency, VCC is ramped up
to an optimized voltage. This voltage is signaled by the SVID Bus to the voltage
regulator. Once the voltage is established, the PLL locks on to the target
frequency.
— If the target frequency is lower than the current frequency, the PLL locks to the
target frequency, then transitions to a lower voltage by signaling the target
voltage on the SVID Bus.
— All active processor cores share the same frequency and voltage. In a multicore processor, the highest frequency P-state requested amongst all active
cores is selected.
— Software-requested transitions are accepted at any time. The processor has a
new capability from the previous processor generation, it can preempt the
previous transition and complete the new request without waiting for this
request to complete.
• The processor controls voltage ramp rates internally to ensure glitch-free
transitions.
• Because there is low transition latency between P-states, a significant number of
transitions per second are possible.
4.2.2
Low-Power Idle States
When the processor is idle, low-power idle states (C-states) are used to save power.
More power savings actions are taken for numerically higher C-states. However, higher
C-states have longer exit and entry latencies. Resolution of C-states occurs at the
thread, processor core, and processor package level. Thread level C-states are
available if Hyper-Threading Technology is enabled. Entry and exit of the C-States at
the thread and core level are shown in Figure 4-2.

While individual threads can request low power C-states, power saving actions only
take place once the core C-state is resolved. Core C-states are automatically resolved
by the processor. For thread and core C-states, a transition to and from C0 is required
before entering any other C-state.
4.2.3
Requesting Low-Power Idle States
The core C-state will be C1E if all actives cores have also resolved a core C1 state
or higher.
The primary software interfaces for requesting low power idle states are through the
MWAIT instruction with sub-state hints and the HLT instruction (for C1 and C1E).
However, software may make C-state requests using the legacy method of I/O reads
from the ACPI-defined processor clock control registers, referred to as P_LVLx. This
method of requesting C-states provides legacy support for operating systems that
initiate C-state transitions via I/O reads.

Power Management
For legacy operating systems, P_LVLx I/O reads are converted within the processor to
the equivalent MWAIT C-state request. Therefore, P_LVLx reads do not directly result in
I/O reads to the system. The feature, known as I/O MWAIT redirection, must be
enabled in the BIOS. To enable it, refer to the Intel® 64 and IA-32 Architectures
Software Developer’s Manual (SDM) Volumes 1, 2, and 3.
Note:
The P_LVLx I/O Monitor address needs to be set up before using the P_LVLx I/O read
interface. Each P-LVLx is mapped to the supported MWAIT(Cx) instruction as follows.
Table 4-8.

Notes
P_LVL2

The P_LVL2 base address is defined in the PMG_IO_CAPTURE MSR,

Developer’s Manual (SDM) Volumes 1, 2, and 3.
P_LVL3
MWAIT(C6)
C6. No sub-states allowed.
P_LVL4
MWAIT(C7)
C7. No sub-states allowed.
The BIOS can write to the C-state range field of the PMG_IO_CAPTURE MSR to restrict
the range of I/O addresses that are trapped and emulate MWAIT like functionality. Any
P_LVLx reads outside of this range does not cause an I/O redirection to MWAIT(Cx) like
request. They fall through like a normal I/O instruction.
Note:
When P_LVLx I/O instructions are used, MWAIT substates cannot be defined. The
MWAIT substate is always zero if I/O MWAIT redirection is used. By default, P_LVLx I/O
redirections enable the MWAIT 'break on EFLAGS.IF’ feature which triggers a wakeup
on an interrupt even if interrupts are masked by EFLAGS.IF.
4.2.4
Core C-states
The following are general rules for all core C-states, unless specified otherwise:
• A core C-State is determined by the lowest numerical thread state (for example,
Thread 0 requests C1E while Thread 1 requests C3, resulting in a core C1E state).
See Table 4-7.
• A core transitions to C0 state when:
— an interrupt occurs.
— there is an access to the monitored address if the state was entered via an
MWAIT instruction.
• For core C1/C1E, and core C3, an interrupt directed toward a single thread wakes
only that thread. However, since both threads are no longer at the same core
C-state, the core resolves to C0.
• An interrupt only wakes the target thread for both C3 and C6 states. Any interrupt
coming into the processor package may wake any core.
4.2.4.1
Core C0 State
The normal operating state of a core where code is being executed.
4.2.4.2
Core C1/C1E State
C1/C1E is a low power state entered when all threads within a core execute a HLT or
MWAIT(C1/C1E) instruction.
92
Intel® Xeon® Processor E5-1600/E5-2600/E5-4600 Product Families

Power Management
A System Management Interrupt (SMI) handler returns execution to either Normal
state or the C1/C1E state. See the Intel® 64 and IA-32 Architectures Software
Developer’s Manual (SDM) Volumes 1, 2, and 3 for more information.
While a core is in C1/C1E state, it processes bus snoops and snoops from other
threads. For more information on C1E, see Section 4.2.5.2, “Package C1/C1E”.
4.2.4.3
Core C3 State
Individual threads of a core can enter the C3 state by initiating a P_LVL2 I/O read to
the P_BLK or an MWAIT(C3) instruction. A core in C3 state flushes the contents of its
L1 instruction cache, L1 data cache, and L2 cache to the shared L3 cache, while
maintaining its architectural state. All core clocks are stopped at this point. Because the
core’s caches are flushed, the processor does not wake any core that is in the C3 state
when either a snoop is detected or when another core accesses cacheable memory.
4.2.4.4
Core C6 State
Individual threads of a core can enter the C6 state by initiating a P_LVL3 I/O read or an
MWAIT(C6) instruction. Before entering core C6, the core will save its architectural
state to a dedicated SRAM. Once complete, a core will have its voltage reduced to zero
volts. In addition to flushing core caches core architecture state is saved to the uncore.
Once the core state save is completed, core voltage is reduced to zero. During exit, the
core is powered on and its architectural state is restored.
4.2.4.5
Core C7 State
Individual threads of a core can enter the C7 state by initiating a P_LVL4 I/O read to
the P_BLK or by an MWAIT(C7) instruction. Core C7 and core C7 substate are the same
as Core C6. The processor does not support LLC flush under any condition.
4.2.4.6
C-State Auto-Demotion
In general, deeper C-states such as C6 or C7 have long latencies and have higher
energy entry/exit costs. The resulting performance and energy penalties become
significant when the entry/exit frequency of a deeper C-state is high. In order to
increase residency in deeper C-states, the processor supports C-state auto-demotion.
There are two C-State auto-demotion options:
• C6/C7 to C3
• C3/C6/C7 To C1
The decision to demote a core from C6/C7 to C3 or C3/C6/C7 to C1 is based on each
core’s immediate residency history. Upon each core C6/C7 request, the core C-state is
demoted to C3 or C1 until a sufficient amount of residency has been established. At
that point, a core is allowed to go into C3/C6 or C7. Each option can be run
concurrently or individually.
This feature is disabled by default. BIOS must enable it in the
PMG_CST_CONFIG_CONTROL register. The auto-demotion policy is also configured by
this register. See the Intel® 64 and IA-32 Architectures Software Developer’s Manual
(SDM) Volumes 1, 2, and 3 for C-state configurations.

Package C-States
The processor supports C0, C1/C1E, C2, C3, and C6 power states. The following is a
summary of the general rules for package C-state entry. These apply to all package
C-states unless specified otherwise:
• A package C-state request is determined by the lowest numerical core C-state
amongst all cores.
• A package C-state is automatically resolved by the processor depending on the
core idle power states and the status of the platform components.
— Each core can be at a lower idle power state than the package if the platform
does not grant the processor permission to enter a requested package C-state.
— The platform may allow additional power savings to be realized in the
processor.
• For package C-states, the processor is not required to enter C0 before entering any
other C-state.
The processor exits a package C-state when a break event is detected. Depending on
the type of break event, the processor does the following:
• If a core break event is received, the target core is activated and the break event
message is forwarded to the target core.
— If the break event is not masked, the target core enters the core C0 state and
the processor enters package C0.
— If the break event is masked, the processor attempts to re-enter its previous
package state.
• If the break event was due to a memory access or snoop request.
— But the platform did not request to keep the processor in a higher package
C-state, the package returns to its previous C-state.
— And the platform requests a higher power C-state, the memory access or snoop
request is serviced and the package remains in the higher power C-state.
The package C-states fall into two categories: independent and coordinated. C0/C1/
C1E are independent, while C2/C3/C6 are coordinated.
Starting with the 2nd Generation Intel(r) Core(TM) Processor Family, package C-states
are based on exit latency requirements which are accumulated from the PCIe* devices,
PCH, and software sources. The level of power savings that can be achieved is a
function of the exit latency requirement from the platform. As a result, there is no fixed
relationship between the coordinated C-state of a package, and the power savings that
will be obtained from the state. Coordinated package C-states offer a range of power
savings which is a function of the guaranteed exit latency requirement from the
platform.
There is also a concept of Execution Allowed (EA), when EA status is 0, the cores in a
socket are in C3 or a deeper state, a socket initiates a request to enter a coordinated
package C-state. The coordination is across all sockets and the PCH.
Table 4-9 shows an example of a dual-core processor package C-state resolution.
Figure 4-3 summarizes package C-state transitions with package C2 as the interim
between PC0 and PC1 prior to PC3 and PC6.

Package C0
The normal operating state for the processor. The processor remains in the normal
state when at least one of its cores is in the C0 or C1 state or when the platform has
not granted permission to the processor to go into a low power state. Individual cores
may be in lower power idle states while the package is in C0.
4.2.5.2
Package C1/C1E
No additional power reduction actions are taken in the package C1 state. However, if
the C1E substate is enabled, the processor automatically transitions to the lowest
supported core clock frequency, followed by a reduction in voltage. Autonomous power
reduction actions which are based on idle timers, can trigger depending on the activity
in the system.
The package enters the C1 low power state when:

Power Management
• At least one core is in the C1 state.
• The other cores are in a C1 or lower power state.
The package enters the C1E state when:
• All cores have directly requested C1E via MWAIT(C1) with a C1E sub-state hint.
• All cores are in a power state lower that C1/C1E but the package low power state is
limited to C1/C1E via the PMG_CST_CONFIG_CONTROL MSR.
• All cores have requested C1 using HLT or MWAIT(C1) and C1E auto-promotion is
enabled in POWER_CTL.
No notification to the system occurs upon entry to C1/C1E.
4.2.5.3
Package C2 State
Package C2 state is an intermediate state which represents the point at which the
system level coordination is in progress. The package cannot reach this state unless all
cores are in at least C3.
The package will remain in C2 when:
• it is awaiting for a coordinated response
• the coordinated exit latency requirements are too stringent for the package to take
any power saving actions
If the exit latency requirements are high enough the package will transition to C3 or C6
depending on the state of the cores.
4.2.5.4
Package C3 State
A processor enters the package C3 low power state when:
• At least one core is in the C3 state.
• The other cores are in a C3 or lower power state, and the processor has been
granted permission by the platform.
• L3 shared cache retains context and becomes inaccessible in this state.
• Additional power savings actions, as allowed by the exit latency requirements,
include putting Intel QPI and PCIe* links in L1, the uncore is not available, further
voltage reduction can be taken.
In package C3, the ring will be off and as a result no accesses to the LLC are possible.
The content of the LLC is preserved.
4.2.5.5
Package C6 State
A processor enters the package C6 low power state when:
• At least one core is in the C6 state.
• The other cores are in a C6 or lower power state, and the processor has been
granted permission by the platform.
• L3 shared cache retains context and becomes inaccessible in this state.

In package C6 state, all cores have saved their architectural state and have had their
core voltages reduced to zero volts. The LLC retains context, but no accesses can be
made to the LLC in this state, the cores must break out to the internal state package C2
for snoops to occur.

System Memory Power Management
The DDR3 power states can be summarized as the following:
• Normal operation (highest power consumption).

Datasheet Volume One
97
Power Management
• CKE Power-Down: Opportunistic, per rank control after idle time. There may be
different levels.
— Active Power-Down.
— Precharge Power-Down with Fast Exit.
— Precharge power Down with Slow Exit.
• Self Refresh: In this mode no transaction is executed. The DDR consumes the
minimum possible power.
4.3.1
CKE Power-Down
The CKE input land is used to enter and exit different power-down modes. The memory
controller has a configurable activity timeout for each rank. Whenever no reads are
present to a given rank for the configured interval, the memory controller will transition
the rank to power-down mode.
The memory controller transitions the DRAM to power-down by de-asserting CKE and
driving a NOP command. The memory controller will tri-state all DDR interface lands
except CKE (de-asserted) and ODT while in power-down. The memory controller will
transition the DRAM out of power-down state by synchronously asserting CKE and
driving a NOP command.
When CKE is off the internal DDR clock is disabled and the DDR power is significantly
reduced.
The DDR defines three levels of power-down:
• Active power-down.
• Precharge power-down fast exit.
• Precharge power-down slow exit.
4.3.2
Self Refresh
The Power Control Unit (PCU) may request the memory controller to place the DRAMs
in self refresh state. Self refresh per channel is supported. The BIOS can put the
channel in self-refresh if software remaps memory to use a subset of all channels. Also
processor channels can enter self refresh autonomously without PCU instruction when
the package is in a package C0 state.
4.3.2.1
Self Refresh Entry
Self refresh entrance can be either disabled or triggered by an idle counter. The idle
counter always clears with any access to the memory controller and remains clear as
long as the memory controller is not drained. As soon as the memory controller is
drained, the counter starts counting, and when it reaches the idle-count, the memory
controller will place the DRAMs in self refresh state.
Power may be removed from the memory controller core at this point. But VCCD supply
(1.5 V or 1.35 V) to the DDR IO must be maintained.
4.3.2.2
Self Refresh Exit
Self refresh exit can be either a message from an external unit or as reaction for an
incoming transaction.

Power Management
4.3.2.3
DLL and PLL Shutdown
Self refresh, according to configuration, may be a trigger for master DLL shut-down
and PLL shut-down. The master DLL shut-down is issued by the memory controller
after the DRAMs have entered self refresh.
The PLL shut-down and wake-up is issued by the PCU. The memory controller gets a
signal from PLL indicating that the memory controller can start working again.
4.3.3
DRAM I/O Power Management
Unused signals are tristated to save power. This includes all signals associated with an
unused memory channel.
The I/O buffer for an unused signal should be tristated (output driver disabled), the
input receiver (differential sense-amp) should be disabled. The input path must be
gated to prevent spurious results due to noise on the unused signals (typically handled
automatically when input receiver is disabled).
4.4
DMI2/PCI Express* Power Management
Active State Power Management (ASPM) support using L1 state, L0s is not supported.

Thermal Management
Specifications
5.1
Package Thermal Specifications
The processor requires a thermal solution to maintain temperatures within operating
limits. Any attempt to operate the processor outside these limits may result in
permanent damage to the processor and potentially other components within the
system, see Section 7.7.1, “Storage Conditions Specifications”. Maintaining the proper
thermal environment is key to reliable, long-term system operation.
A complete solution includes both component and system level thermal management
features. Component level thermal solutions can include active or passive heatsinks
attached to the processor integrated heat spreader (IHS). Typical system level thermal
solutions may consist of system fans combined with ducting and venting.
This section provides data necessary for developing a complete thermal solution. For
more information on designing a component level thermal solution, refer to the Intel®
Xeon® Processor E5-1600/E5-2600/E5-4600 Product Families Thermal/Mechanical
Design Guide.
5.1.1
Thermal Specifications
To allow optimal operation and long-term reliability of Intel processor-based systems,
the processor must remain within the minimum and maximum case temperature
(TCASE) specifications as defined by the applicable thermal profile. Thermal solutions
not designed to provide sufficient thermal capability may affect the long-term reliability
of the processor and system. For more details on thermal solution design, please refer
to the Intel® Xeon® Processor E5-1600/E5-2600/E5-4600 Product Families Thermal/
Mechanical Design Guide.
The processors implement a methodology for managing processor temperatures which
is intended to support acoustic noise reduction through fan speed control and to assure
processor reliability. Selection of the appropriate fan speed is based on the relative
temperature data reported by the processor’s Platform Environment Control Interface
(PECI) as described in Section 2.5, “Platform Environment Control Interface (PECI)”.
If the DTS value is less than TCONTROL, then the case temperature is permitted to
exceed the Thermal Profile, but the DTS value must remain at or below TCONTROL.
For TCASE implementations, if DTS is greater than TCONTROL, then the case
temperature must meet the TCASE based Thermal Profiles.
For DTS implementations:
• TCASE thermal profile can be ignored during processor run time.
• If DTS is greater than Tcontrol then follow DTS thermal profile specifications for fan
speed optimization.
Intel® Xeon® Processor E5-1600/E5-2600/E5-4600 Product Families
Datasheet Volume One
101
Thermal Management Specifications
The temperature reported over PECI is always a negative value and represents a delta
below the onset of thermal control circuit (TCC) activation, as indicated by PROCHOT_N
(see Section 7, “Electrical Specifications”). Systems that implement fan speed control
must be designed to use this data. Systems that do not alter the fan speed need to
guarantee the case temperature meets the thermal profile specifications.
Some processor SKUs support two thermal profiles; refer to Table 5-1for a summary of
the planned SKUs and their supported thermal profiles. Both ensure adherence to Intel
reliability requirements. Thermal Profile 2U is representative of a volumetrically
unconstrained thermal solution (that is, industry enabled 2U heatsink). With single
thermal profile, it is expected that the Thermal Control Circuit (TCC) would be activated
for very brief periods of time when running the most power intensive applications.
Thermal Profile 1U is indicative of a constrained thermal environment (that is, 1U form
factor). Because of the reduced cooling capability represented by this thermal solution,
the probability of TCC activation and performance loss is increased. Additionally,
utilization of a thermal solution that does not meet Thermal Profile 1U will violate the
thermal specifications and may result in permanent damage to the processor. Refer to
the Intel® Xeon® Processor E5-1600/E5-2600/E5-4600 Product Families Thermal/
Mechanical Design Guide for details on system thermal solution design, thermal profiles
and environmental considerations. The upper point of the thermal profile consists of the
Thermal Design Power (TDP) and the associated TCASE value. It should be noted that
the upper point associated with Thermal Profile 1U.
(x = TDP and y = TCASE_MAX_B @ TDP) represents a thermal solution design point. In
actuality the processor case temperature will not reach this value due to TCC
activation.
For Embedded Servers, Communications and storage markets Intel has plan SKU’s that
support Thermal Profiles with nominal and short-term conditions designed to meet
NEBS level 3 compliance. For these SKU’s operation at either the nominal or short-term
thermal profiles should result in virtually no TCC activation. Thermal Profiles for these
SKU’s are found in Table 5-1.
Intel recommends that complete thermal solution designs target the Thermal Design
Power (TDP). The Adaptive Thermal Monitor feature is intended to help protect the
processor in the event that an application exceeds the TDP recommendation for a
sustained time period. To ensure maximum flexibility for future requirements, systems
should be designed to the Flexible Motherboard (FMB) guidelines, even if a processor
with lower power dissipation is currently planned. The Adaptive Thermal Monitor
feature must be enabled for the processor to remain within its specifications.
5.1.2
TCASE and DTS Based Thermal Specifications
To simplify compliance to thermal specifications at processor run time, the processor
has added a Digital Thermal Sensor (DTS) based thermal specification. Digital Thermal
Sensor reports a relative die temperature as an offset from TCC activation
temperature. TCASE thermal based specifications are used for heat sink sizing and DTS
based specs are used for acoustic and fan speed optimizations. For the processor
family, firmware (for example, BMC or other platform management devices) will have
DTS based specifications for all SKUs programmed by the customer. 8-core and 6-core
SKUs may share TCASE thermal profiles but they will have separate TDTS based thermal
profiles. See Table 5-1 for the TCASE and DTS SKU summary.
The processor fan speed control is managed by comparing DTS thermal readings via
PECI against the processor-specific fan speed control reference point, or Tcontrol. Both
Tcontrol and DTS thermal readings are accessible via the processor PECI client. At a
one time readout only, the Fan Speed Control firmware will read the following:

Embedded server SKU. The thermal solution is expected to be developed in accordance
with the Tcase thermal profile. Operational compliance monitoring of thermal
specifications and fan speed modulation may be done via the DTS based thermal
profile. The slope of a DTS profile assumes full fan speed which is not required over
much of the power range. At most power levels on embedded SKU’s, temperatures of
the nominal profile are less than Tcontrol as indicated by the blue shaded region in each
DTS profile graph. As a further simplification, operation at DTS temperatures up to
Tcontrol is permitted at all power levels. Compliance to the DTS profile is required for
any temperatures exceeding Tcontrol.

Processor Core Thermal Features
5.2.1
Processor Temperature
A new feature in the processor is a software readable field in the
TEMPERATURE_TARGET MSR register that contains the minimum temperature at which
the TCC will be activated and PROCHOT_N will be asserted. The TCC activation
temperature is calibrated on a part-by-part basis and normal factory variation may
result in the actual TCC activation temperature being higher than the value listed in the
register. TCC activation temperatures may change based on processor stepping,
frequency or manufacturing efficiencies.
5.2.2
Adaptive Thermal Monitor
The Adaptive Thermal Monitor feature provides an enhanced method for controlling the
processor temperature when the processor silicon reaches its maximum operating
temperature. Adaptive Thermal Monitor uses Thermal Control Circuit (TCC) activation
to reduce processor power via a combination of methods. The first method (Frequency/
SVID control) involves the processor adjusting its operating frequency (via the core
ratio multiplier) and input voltage (via the SVID signals). This combination of reduced
frequency and voltage results in a reduction to the processor power consumption. The
second method (clock modulation) reduces power consumption by modulating (starting
and stopping) the internal processor core clocks. The processor intelligently selects the
appropriate TCC method to use on a dynamic basis. BIOS is not required to select a
specific method.
The Adaptive Thermal Monitor feature must be enabled for the processor to be
operating within specifications. Snooping and interrupt processing are performed in
the normal manner while the TCC is active.
With a properly designed and characterized thermal solution, it is anticipated that the
TCC would be activated for very short periods of time when running the most power
intensive applications. The processor performance impact due to these brief periods of
TCC activation is expected to be so minor that it would be immeasurable. An underdesigned thermal solution that is not able to prevent excessive activation of the TCC in
the anticipated ambient environment may cause a noticeable performance loss, and in
some cases may result in a TC that exceeds the specified maximum temperature which
may affect the long-term reliability of the processor. In addition, a thermal solution that
is significantly under-designed may not be capable of cooling the processor even when
the TCC is active continuously. Refer to the Intel® Xeon® Processor E5-1600/E5-2600/
E5-4600 Product Families Thermal/Mechanical Design Guide for information on
designing a compliant thermal solution.
The duty cycle for the TCC, when activated by the Thermal Monitor, is factory
configured and cannot be modified. The Thermal Monitor does not require any
additional hardware, software drivers, or interrupt handling routines.

Intel® Xeon® Processor E5-1600/E5-2600/E5-4600 Product Families
Datasheet Volume One
5.2.2.1
Frequency/SVID Control
The processor uses Frequency/SVID control whereby TCC activation causes the
processor to adjust its operating frequency (via the core ratio multiplier) and VCC input
voltage (via the SVID signals). This combination of reduced frequency and voltage
results in a reduction to the processor power consumption.
This method includes multiple operating points, each consisting of a specific operating
frequency and voltage. The first operating point represents the normal operating
condition for the processor. The remaining points consist of both lower operating
frequencies and voltages. When the TCC is activated, the processor automatically
transitions to the new lower operating frequency. This transition occurs very rapidly (on
the order of microseconds).Once the new operating frequency is engaged, the
processor will transition to the new core operating voltage by issuing a new SVID code
to the VCC voltage regulator. The voltage regulator must support dynamic SVID steps
to support this method. During the voltage change, it will be necessary to transition
through multiple SVID codes to reach the target operating voltage. Each step will be
one SVID table entry (see Table 7-3). The processor continues to execute instructions
during the voltage transition. Operation at the lower voltages reduces the power
consumption of the processor.
A small amount of hysteresis has been included to prevent rapid active/inactive
transitions of the TCC when the processor temperature is near its maximum operating
temperature. Once the temperature has dropped below the maximum operating
temperature, and the hysteresis timer has expired, the operating frequency and
voltage transition back to the normal system operating point via the intermediate
SVID/frequency points. Transition of the SVID code will occur first, to insure proper
operation once the processor reaches its normal operating frequency. Refer to
Figure 5-33 for an illustration of this ordering.

5.2.2.2
Clock Modulation
Clock modulation is performed by alternately turning the clocks off and on at a duty
cycle specific to the processor (factory configured to 37.5% on and 62.5% off for TM1).
The period of the duty cycle is configured to 32 microseconds when the TCC is active.
Cycle times are independent of processor frequency. A small amount of hysteresis has
been included to prevent rapid active/inactive transitions of the TCC when the
processor temperature is near its maximum operating temperature. Once the
temperature has dropped below the maximum operating temperature, and the
hysteresis timer has expired, the TCC goes inactive and clock modulation ceases. Clock
modulation is automatically engaged as part of the TCC activation when the Frequency/
SVID targets are at their minimum settings. It may also be initiated by software at a
configurable duty cycle.
5.2.3
On-Demand Mode
The processor provides an auxiliary mechanism that allows system software to force
the processor to reduce its power consumption. This mechanism is referred to as “OnDemand” mode and is distinct from the Adaptive Thermal Monitor feature. On-Demand
mode is intended as a means to reduce system level power consumption. Systems
must not rely on software usage of this mechanism to limit the processor temperature.
If bit 4 of the IA32_CLOCK_MODULATION MSR is set to a ‘1’, the processor will
immediately reduce its power consumption via modulation (starting and stopping) of
the internal core clock, independent of the processor temperature. When using OnDemand mode, the duty cycle of the clock modulation is programmable via bits 3:0 of
the same IA32_CLOCK_MODULATION MSR. In On-Demand mode, the duty cycle can
be programmed from 6.25% on / 93.75% off to 93.75% on / 6.25% off in 6.25%
increments. On-Demand mode may be used in conjunction with the Adaptive Thermal
Monitor; however, if the system tries to enable On-Demand mode at the same time the
TCC is engaged, the factory configured duty cycle of the TCC will override the duty
cycle selected by the On-Demand mode.
5.2.4
PROCHOT_N Signal
An external signal, PROCHOT_N (processor hot), is asserted when the processor core
temperature has reached its maximum operating temperature. If Adaptive Thermal
Monitor is enabled (note it must be enabled for the processor to be operating within
specification), the TCC will be active when PROCHOT_N is asserted. The processor can
be configured to generate an interrupt upon the assertion or de-assertion of
PROCHOT_N.
The PROCHOT_N signal is bi-directional in that it can either signal when the processor
(any core) has reached its maximum operating temperature or be driven from an
external source to activate the TCC. The ability to activate the TCC via PROCHOT_N can
provide a means for thermal protection of system components.
As an output, PROCHOT_N will go active when the processor temperature monitoring
sensor detects that one or more cores has reached its maximum safe operating
temperature. This indicates that the processor Thermal Control Circuit (TCC) has been
activated, if enabled. As an input, assertion of PROCHOT_N by the system will activate
the TCC, if enabled, for all cores. TCC activation due to PROCHOT_N assertion by the
system will result in the processor immediately transitioning to the minimum frequency
and corresponding voltage (using Freq/SVID control). Clock modulation is not activated
in this case. The TCC will remain active until the system de-asserts PROCHOT_N.
140
Intel® Xeon® Processor E5-1600/E5-2600/E5-4600 Product Families
Datasheet Volume One
PROCHOT_N can allow voltage regulator (VR) thermal designs to target maximum
sustained current instead of maximum current. Systems should still provide proper
cooling for the VR, and rely on PROCHOT_N as a backup in case of system cooling
failure. The system thermal design should allow the power delivery circuitry to operate
within its temperature specification even while the processor is operating at its Thermal
Design Power.
With a properly designed and characterized thermal solution, it is anticipated that
PROCHOT_N will be asserted for very short periods of time when running the most
power intensive applications. An under-designed thermal solution that is not able to
prevent excessive assertion of PROCHOT_N in the anticipated ambient environment
may cause a noticeable performance loss. Refer to the appropriate platform design
guide and for details on implementing the bi-directional PROCHOT_N feature.
5.2.5
THERMTRIP_N Signal
Regardless of whether Adaptive Thermal Monitor is enabled, in the event of a
catastrophic cooling failure, the processor will automatically shut down when the silicon
has reached an elevated temperature (refer to the THERMTRIP_N definition in
Section 6, “Signal Descriptions”). At this point, the THERMTRIP_N signal will go active
and stay active. THERMTRIP_N activation is independent of processor activity and does
not generate any Intel QuickPath Interconnect transactions. If THERMTRIP_N is
asserted, all processor supplies (VCC, VTTA, VTTD, VSA, VCCPLL, VCCD) must be
removed within the timeframe provided. The temperature at which THERMTRIP_N
asserts is not user configurable and is not software visible.
5.2.6
Integrated Memory Controller (IMC) Thermal Features
5.2.6.1
DRAM Throttling Options
The Integrated Memory Controller (IMC) has two, independent mechanisms that cause
system memory throttling:
• Open Loop Thermal Throttling (OLTT) and Hybrid OLTT (OLTT_Hybrid)
• Closed Loop Thermal Throttling (CLTT) and Hybrid CLTT (CLTT_Hybrid)
5.2.6.1.1
Open Loop Thermal Throttling (OLTT)
Pure energy based estimation for systems with no BMC or Intel ME. No memory
temperature information is provided by the platform or DIMMs. The CPU is informed of
the ambient temperature estimate by the BIOS or by a device via the PECI interface.
DIMM temperature estimates and bandwidth control are monitored and managed by
the PCU on a per rank basis.
5.2.6.1.2
Hybrid Open Loop Thermal Throttling (OLTT_Hybrid)
Temperature information is provided by the platform (for example, BMC or Intel®
Management Engine (Intel® ME)) through PECI and the PCU interpolates gaps with
energy based estimations.
5.2.6.1.3
Closed Loop Thermal Throttling (CLTT)
The processor periodically samples temperatures from the DIMM TSoD devices over a
programmable interval. The PCU determines the hottest DIMM rank from TSoD data
and informs the integrated memory controller for use in bandwidth throttling decisions.
Intel® Xeon® Processor E5-1600/E5-2600/E5-4600 Product Families
Datasheet Volume One
141
5.2.6.2
Hybrid Closed Loop Thermal Throttling (CLTT_Hybrid)
The processor periodically samples temperature from the DIMM TSoD devices over a
programmable interval and interpolates gaps or the BMC/Intel ME samples a
motherboard thermal sensor in the memory subsection and provides this data to the
PCU via the PECI interface. This data is combined with an energy based estimations
calculated by the PCU. When needed, system memory is then throttled using CAS
bandwidth control. The processor supports dynamic reprogramming of the memory
thermal limits based on system thermal state by the BMC or Intel ME.
5.2.6.3
MEM_HOT_C01_N and MEM_HOT_C23_N Signal
The processor includes a pair of new bi-directional memory thermal status signals
useful for manageability schemes. Each signal presents and receives thermal status for
a pair of memory channels (channels 0 and 1 and channels 2 and 3).
• Input Function: The processor can periodically sense the MEM_HOT_{C01/C23}_N
signals to detect if the platform is requesting a memory throttling event.
Manageability hardware could drive this signal due to a memory voltage regulator
thermal or electrical issue or because of a detected system thermal event (for
example, fan is going to fail) other system devices are exceeding their thermal
target. The input sense period of these signals are programmable, 100 us is the
default value. The input sense assertion time recognized by the processor is
programmable, 1 us is the default value. If the sense assertion time is programmed
to zero, then the processor ignores all external assertions of MEM_HOT_{C01/
C23}_N signals (in effect they become outputs).
• Output Function: The output behavior of the MEM_HOT_{C01/C23}_N signals
supports Level mode. In this mode, MEM_HOT_{C01/C23}_N event temperatures
are programmable via TEMP_OEM_HI, TEMP_LOW, TEMP_MID, and TEMP_HI
threshold settings in the iMC. In Level mode, when asserted, the signal indicates to
the platform that a BIOS-configured thermal threshold has been reached by one or
more DIMMs in the covered channel pair.
5.2.6.4
Integrated Dual SMBus Master Controllers for SMI
The processor includes two integrated SMBus master controllers running at 100 KHz for
dedicated PCU access to the serial presence detect (SPD) devices and thermal sensors
(TSoD) on the DIMMs. Each controller is responsible for a pair of memory channels and
supports up to eight SMBus slave devices. Note that clock-low stretching is not
supported by the processor. To avoid design complexity and minimize package C-state
transitions, the SMBus interface between the processor and DIMMs must be connected.
The SMBus controllers for the system memory interface support the following SMBus
protocols/commands:
• Random byte Read
• Byte Write
• I2C* Write to Pointer Register
• I2C Present Pointer Register Word Read
• I2C Pointer Write Register Read.
Refer to the System Management Bus (SMBus) Specification, Revision 2.0 for standing
timing protocols and specific command structure details.

Description
BIST_ENABLE
BIST Enable Strap. Input which allows the platform to enable or disable built-in self test
(BIST) on the processor. This signal is pulled up on the die, refer to Table 7-6 for details.
BMCINIT
BMC Initialization Strap. Indicates whether Service Processor Boot Mode should be used.
Used in combination with FRMAGENT and SOCKET_ID inputs.
• 0: Service Processor Boot Mode Disabled. Example boot modes: Local PCH (this
processor hosts a legacy PCH with firmware behind it), Intel QPI Link Boot (for
processors one hop away from the FW agent), or Intel QPI Link Init (for processors
more than one hop away from the firmware agent).
• 1: Service Processor Boot Mode Enabled. In this mode of operation, the processor
performs the absolute minimum internal configuration and then waits for the Service
Processor to complete its initialization. The socket boots after receiving a “GO”
handshake signal via a firmware scratchpad register.
This signal is pulled down on the die, refer to Table 7-6 for details.
CAT_ERR_N
Indicates that the system has experienced a fatal or catastrophic error and cannot
continue to operate. The processor will assert CAT_ERR_N for nonrecoverable machine
check errors and other internal unrecoverable errors. It is expected that every processor
in the system will wire-OR CAT_ERR_N for all processors. Since this is an I/O land,
external agents are allowed to assert this land which will cause the processor to take a
machine check exception. This signal is sampled after PWRGOOD assertion.
On the processor, CAT_ERR_N is used for signaling the following types of errors:
• Legacy MCERR’s, CAT_ERR_N is asserted for 16 BCLKs.
• Legacy IERR’s, CAT_ERR_N remains asserted until warm or cold reset.
CPU_ONLY_RESET
Resets all the processors on the platform without resetting the DMI2 links.
ERROR_N[2:0]
Error status signals for integrated I/O (IIO) unit:
• 0 = Hardware correctable error (no operating system or firmware action necessary)
• 1 = Non-fatal error (operating system or firmware action required to contain and
recover)
• 2 = Fatal error (system reset likely required to recover)
FRMAGENT
Bootable Firmware Agent Strap. This input configuration strap used in combination with
SOCKET_ID to determine whether the socket is a legacy socket, bootable firmware agent
is present, and DMI links are used in PCIe* mode (instead of DMI2 mode).
The firmware flash ROM is located behind the local PCH attached to the processor via the
DMI2 interface.This signal is pulled down on the die, refer to Table 7-6 for details.
MEM_HOT_C01_N
MEM_HOT_C23_N
Memory throttle control. MEM_HOT_C01_N and MEM_HOT_C23_N signals have two
modes of operation – input and output mode.
Input mode is externally asserted and is used to detect external events such as VR_HOT#
from the memory voltage regulator and causes the processor to throttle the appropriate
memory channels.
Output mode is asserted by the processor known as level mode. In level mode, the
output indicates that a particular branch of memory subsystem is hot.
MEM_HOT_C01_N is used for memory channels 0 & 1 while MEM_HOT_C23_N is used for
memory channels 2 & 3.

Signal Name
Description
PROCHOT_N
PROCHOT_N will go active when the processor temperature monitoring sensor detects
that the processor has reached its maximum safe operating temperature. This indicates
that the processor Thermal Control Circuit has been activated, if enabled. This signal can
also be driven to the processor to activate the Thermal Control Circuit. This signal is
sampled after PWRGOOD assertion.
If PROCHOT_N is asserted at the deassertion of RESET_N, the processor will tristate its
outputs.
PWRGOOD
Power Good is a processor input. The processor requires this signal to be a clean
indication that BCLK, VTTA/VTTD, VSA, VCCPLL, and VCCD_01 and VCCD_23 supplies are
stable and within their specifications.
“Clean” implies that the signal will remain low (capable of sinking leakage current),
without glitches, from the time that the power supplies are turned on until they come
within specification. The signal must then transition monotonically to a high state.
PWRGOOD can be driven inactive at any time, but clocks and power must again be stable
before a subsequent rising edge of PWRGOOD. PWRGOOD transitions from inactive to
active when all supplies except VCC are stable. VCC has a VBOOT of zero volts and is not
included in PWRGOOD indication in this phase. However, for the active to inactive
transition, if any CPU power supply (VCC, VTTA/VTTD, VSA, VCCD, or VCCPLL) is about to
fail or is out of regulation, the PWRGOOD is to be negated.
The signal must be supplied to the processor; it is used to protect internal circuits against
voltage sequencing issues. It should be driven high throughout boundary scan operation.
Note: VCC has a Vboot setting of 0.0V and is not included in the PWRGOOD indication
and VSA has a Vboot setting of 0.9V. Refer to the VR12/IMVP7 Pulse Width
Modulation Specification.
RESET_N
Asserting the RESET_N signal resets the processor to a known state and invalidates its
internal caches without writing back any of their contents. Note some PLL, Intel
QuickPath Interconnect and error states are not effected by reset and only PWRGOOD
forces them to a known state.
RSVD
RESERVED. All signals that are RSVD must be left unconnected on the board. Refer to
Section 7.1.10, “Reserved or Unused Signals” for details.
SAFE_MODE_BOOT
Safe mode boot Strap. SAFE_MODE_BOOT allows the processor to wake up safely by
disabling all clock gating, this allows BIOS to load registers or patches if required. This
signal is sampled after PWRGOOD assertion. The signal is pulled down on the die, refer to
Table 7-6 for details.
SOCKET_ID[1:0]
Socket ID Strap. Socket identification configuration straps for establishing the PECI
address, Intel QPI Node ID, and other settings. This signal is used in combination with
FRMAGENT to determine whether the socket is a legacy socket, bootable firmware agent
is present, and DMI links are used in PCIe* mode (instead of DMI2 mode). Each
processor socket consumes one Node ID, and there are 128 Home Agent tracker entries.
This signal is pulled down on the die, refer to Table 7-6 for details.
TEST[4:0]
Test[4:0] must be individually connected to an appropriate power source or ground
through a resistor for proper processor operation. Refer to the appropriate Platform
Design Guide (PDG) for additional implementation details.
THERMTRIP_N
Assertion of THERMTRIP_N (Thermal Trip) indicates one of two possible critical overtemperature conditions: One, the processor junction temperature has reached a level
beyond which permanent silicon damage may occur and Two, the system memory
interface has exceeded a critical temperature limit set by BIOS. Measurement of the
processor junction temperature is accomplished through multiple internal thermal
sensors that are monitored by the Digital Thermal Sensor (DTS). Simultaneously, the
Power Control Unit (PCU) monitors external memory temperatures via the dedicated
SMBus interface to the DIMMs. If any of the DIMMs exceed the BIOS defined limits, the
PCU will signal THERMTRIP_N to prevent damage to the DIMMs. Once activated, the
processor will stop all execution and shut down all PLLs. To further protect the processor,
its core voltage (VCC), VTTA, VTTD, VSA, VCCPLL, VCCD supplies must be removed
following the assertion of THERMTRIP_N. Once activated, THERMTRIP_N remains latched
until RESET_N is asserted. While the assertion of the RESET_N signal may de-assert
THERMTRIP_N, if the processor's junction temperature remains at or above the trip level,
THERMTRIP_N will again be asserted after RESET_N is de-asserted. This signal can also
be asserted if the system memory interface has exceeded a critical temperature limit set
by BIOS. This signal is sampled after PWRGOOD assertion.

and BCLK{0/1}_DN signals. There is no direct link between core frequency and Intel
QuickPath Interconnect link frequency (for example, no core frequency to Intel
QuickPath Interconnect multiplier). The processor maximum core frequency, Intel
QuickPath Interconnect link frequency and DDR memory frequency are set during
manufacturing. It is possible to override the processor core frequency setting using
software. This permits operation at lower core frequencies than the factory set
maximum core frequency.

Electrical Specifications
The processor core frequency is configured during reset by using values stored within
the device during manufacturing. The stored value sets the lowest core multiplier at
which the particular processor can operate. If higher speeds are desired, the
appropriate ratio can be configured via the IA32_PERF_CTL MSR (MSR 199h); Bits
[15:0].
Clock multiplying within the processor is provided by the internal phase locked loop
(PLL), which requires a constant frequency BCLK{0/1}_DP, BCLK{0/1}_DN input, with
exceptions for spread spectrum clocking. DC specifications for the BCLK{0/1}_DP,
BCLK{0/1}_DN inputs are provided in Table 7-18. These specifications must be met
while also meeting the associated signal quality specifications outlined in Section 7.9.
7.1.6.1
PLL Power Supply
An on-die PLL filter solution is implemented on the processor. Refer to Table 7-11 for
DC specifications and to the applicable platform design guide for decoupling and
routing guidelines.
7.1.7
JTAG and Test Access Port (TAP) Signals
Due to the voltage levels supported by other components in the JTAG and Test Access
Port (TAP) logic, Intel recommends the processor be first in the TAP chain, followed by
any other components within the system. Please refer to the Intel® Xeon® Processor
E5-1600/E5-2600/E5-4600 Product Families – BSDL (Boundary Scan Description
Language) for more details. A translation buffer should be used to connect to the rest
of the chain unless one of the other components is capable of accepting an input of the
appropriate voltage. Two copies of each signal may be required with each driving a
different voltage level.
7.1.8
Processor Sideband Signals
The processor include asynchronous sideband signals that provide asynchronous input,
output or I/O signals between the processor and the platform or Platform Controller
Hub. Details can be found in Table 7-5 and the applicable platform design guide.
All Processor Asynchronous Sideband input signals are required to be asserted/
deasserted for a defined number of BCLKs in order for the processor to recognize the
proper signal state. Refer to Section 7.9 for applicable signal integrity specifications.
7.1.9
Power, Ground and Sense Signals
Processors also include various other signals including power/ground and sense points.
Details can be found in Table 7-5 and the applicable platform design guide.
7.1.9.1
Power and Ground Lands
All VCC, VCCPLL, VSA, VCCD, VTTA, and VTTD lands must be connected to their respective
processor power planes, while all VSS lands must be connected to the system ground
plane. Refer to the applicable platform design guide for decoupling, voltage plane and
routing guidelines for each power supply voltage.
For clean on-chip power distribution, processors include lands for all required voltage
supplies. These are listed in Table 7-1.

Decoupling Guidelines
Due to its large number of transistors and high internal clock speeds, the processor is
capable of generating large current swings between low and full power states. This may
cause voltages on power planes to sag below their minimum values if bulk decoupling is
not adequate. Large electrolytic bulk capacitors (CBULK), help maintain the output
voltage during current transients, for example coming out of an idle condition. Care
must be taken in the baseboard design to ensure that the voltages provided to the
processor remain within the specifications listed in Table 7-11. Failure to do so can
result in timing violations or reduced lifetime of the processor. For further information,
refer to the appropriate Platform Design Guide (PDG).
7.1.9.3
Voltage Identification (VID)
The Voltage Identification (VID) specification for the VCC, VSA, VCCD voltage are defined
by the VR12/IMVP7 Pulse Width Modulation Specification. The reference voltage or the
VID setting is set via the SVID communication bus between the processor and the
voltage regulator controller chip. The VID settings are the nominal voltages to be
delivered to the processor's VCC, VSA, VCCD lands. Table 7-3 specifies the reference
voltage level corresponding to the VID value transmitted over serial VID. The VID codes
will change due to temperature and/or current load changes in order to minimize the
power and to maximize the performance of the part. The specifications are set so that a
voltage regulator can operate with all supported frequencies.
Individual processor VID values may be calibrated during manufacturing such that two
processor units with the same core frequency may have different default VID settings.
The processor uses voltage identification signals to support automatic selection of VCC,
VSA, and VCCD power supply voltages. If the processor socket is empty (SKTOCC_N
high), or a “not supported” response is received from the SVID bus, then the voltage
regulation circuit cannot supply the voltage that is requested, the voltage regulator
must disable itself or not power on. Vout MAX register (30h) is programmed by the
processor to set the maximum supported VID code and if the programmed VID code is
156

Electrical Specifications
higher than the VID supported by the VR, then VR will respond with a “not supported”
acknowledgement. See the VR12/IMVP7 Pulse Width Modulation Specification for
further details.
7.1.9.3.1
SVID Commands
The processor provides the ability to operate while transitioning to a new VID setting
and its associated processor voltage rails (VCC, VSA, and VCCD). This is represented by a
DC shift. It should be noted that a low-to-high or high-to-low voltage state change may
result in as many VID transitions as necessary to reach the target voltage. Transitions
above the maximum specified VID are not supported. The processor supports the
following VR commands:
• SetVID_fast (20 mV/µs for VCC,10 mV/µs for VSA/VCCD),
• SetVID_slow (5 mV/µs for VCC, 2.5 mV/µs for VSA/VCCD), and
• Slew Rate Decay (downward voltage only and it’s a function of the output
capacitance’s time constant) commands. Table 7-3 and Table 7-21 includes SVID
step sizes and DC shift ranges. Minimum and maximum voltages must be
maintained as shown in Table 7-11.
The VRM or EVRD utilized must be capable of regulating its output to the value defined
by the new VID. The VR12/IMVP7 Pulse Width Modulation Specification contains further
details.
Power source characteristics must be guaranteed to be stable whenever the supply to
the voltage regulator is stable.
7.1.9.3.2
SetVID Fast Command
The SetVID-fast command contains the target VID in the payload byte. The range of
voltage is defined in the VID table. The VR should ramp to the new VID setting with a
fast slew rate as defined in the slew rate data register. Typically 10 to 20 mV/µs
depending on platform, voltage rail, and the amount of decoupling capacitance.
The SetVID-fast command is preemptive, the VR interrupts its current processes and
moves to the new VID. The SetVID-fast command operates on 1 VR address at a time.
This command is used in the processor for package C6 fast exit and entry.
7.1.9.3.3
SetVID Slow Command
The SetVID-slow command contains the target VID in the payload byte. The range of
voltage is defined in the VID table. The VR should ramp to the new VID setting with a
“slow” slew rate as defined in the slow slew rate data register. The SetVID_Slow is 1/4
slower than the SetVID_fast slew rate.
The SetVID-slow command is preemptive, the VR interrupts its current processes and
moves to the new VID. This is the instruction used for normal P-state voltage change.
This command is used in the processor for the Intel Enhanced SpeedStep Technology
transitions.
7.1.9.3.4
SetVID-Decay Command
The SetVID-Decay command is the slowest of the DVID transitions. It is only used for
VID down transitions. The VR does not control the slew rate, the output voltage
declines with the output load current only.
The SetVID- Decay command is preemptive, that is, the VR interrupts its current
processes and moves to the new VID.

7.1.9.3.5
SVID Power State Functions: SetPS
The processor has three power state functions and these will be set seamlessly via the
SVID bus using the SetPS command. Based on the power state command, the SetPS
commands sends information to VR controller to configure the VR to improve efficiency,
especially at light loads. For example, typical power states are:
• PS0(00h): Represents full power or active mode
• PS1(01h): Represents a light load 5 A to 20 A
• PS2(02h): Represents a very light load <5 A
The VR may change its configuration to meet the processor’s power needs with greater
efficiency. For example, it may reduce the number of active phases, transition from
CCM (Continuous Conduction Mode) to DCM (Discontinuous Conduction Mode) mode,
reduce the switching frequency or pulse skip, or change to asynchronous regulation.
For example, typical power states are 00h = run in normal mode; a command of 01h=
shed phases mode, and an 02h=pulse skip.
The VR may reduce the number of active phases from PS0 to PS1 or PS0 to PS2 for
example. There are multiple VR design schemes that can be used to maintain a greater
efficiency in these different power states, please work with your VR controller suppliers
for optimizations.
The SetPS command sends a byte that is encoded as to what power state the VR
should transition to.
If a power state is not supported by the controller, the slave should acknowledge with
command rejected (11b)
Note the mapping of power states 0-n will be detailed in the VR12/IMVP7 Pulse Width
Modulation Specification.
If the VR is in a low power state and receives a SetVID command moving the VID up
then the VR exits the low power state to normal mode (PS0) to move the voltage up as
fast as possible. The processor must re-issue low power state (PS1 or PS2) command if
it is in a low current condition at the new higher voltage. See Figure 7-2 for VR power
state transitions.

Reserved or Unused Signals
All Reserved (RSVD) signals must not be connected. Connection of these signals to VCC,
VTTA, VTTD, VCCD, VCCPLL, VSS, or to any other signal (including each other) can result in
component malfunction or incompatibility with future processors. See Chapter 8,
“Processor Land Listing” for a land listing of the processor and the location of all
Reserved signals.
For reliable operation, always connect unused inputs or bi-directional signals to an
appropriate signal level. Unused active high inputs should be connected through a
resistor to ground (VSS). Unused outputs maybe left unconnected; however, this may
interfere with some Test Access Port (TAP) functions, complicate debug probing, and
prevent boundary scan testing. A resistor must be used when tying bi-directional
signals to power or ground. When tying any signal to power or ground, a resistor will
also allow for system testability. Resistor values should be within ± 20% of the
impedance of the baseboard trace, unless otherwise noted in the appropriate platform
design guidelines.

Power-On Configuration (POC) Options
Several configuration options can be configured by hardware. The processor samples
its hardware configuration at reset, on the active-to-inactive transition of RESET_N, or
upon assertion of PWRGOOD (inactive-to-active transition). For specifics on these
options, please refer to Table 7-7.
The sampled information configures the processor for subsequent operation. These
configuration options cannot be changed except by another reset transition of the
latching signal (RESET_N or PWRGOOD).

7.4
Fault Resilient Booting (FRB)
The processor supports both socket and core level Fault Resilient Booting (FRB), which
provides the ability to boot the system as long as there is one processor functional in
the system. One limitation to socket level FRB is that the system cannot boot if the
legacy socket that connects to an active PCH becomes unavailable since this is the path
to the system BIOS. See Table 7-8 for a list of output tri-state FRB signals.
Socket level FRB will tri-state processor outputs via the PROCHOT_N signal. Assertion
of the PROCHOT_N signal through RESET_N de-assertion will tri-state processor
outputs. Note, that individual core disabling is also supported for those cases where
disabling the entire package is not desired.
The processor extends the FRB capability to the core granularity by maintaining a
register in the uncore so that BIOS or another entity can disable one or more specific
processor cores.

Mixing Processors
Intel supports and validates and four two processor configurations only in which all
processors operate with the same Intel QuickPath Interconnect frequency, core
frequency, power segment, and have the same internal cache sizes. Mixing
components operating at different internal clock frequencies is not supported and will
not be validated by Intel. Combining processors from different power segments is also
not supported.
Note:
Processors within a system must operate at the same frequency per bits [15:8] of the
FLEX_RATIO MSR (Address: 194h); however this does not apply to frequency
transitions initiated due to thermal events, Extended HALT, Enhanced Intel SpeedStep

Technology transitions signal. Please refer to the Intel® 64 and IA-32 Architectures
Software Developer’s Manual (SDM) Volumes 1, 2, and 3 for details on the FLEX_RATIO
MSR and setting the processor core frequency.
Not all operating systems can support dual processors with mixed frequencies. Mixing
processors of different steppings but the same model (as per CPUID instruction) is
supported provided there is no more than one stepping delta between the processors,
for example, S and S+1.
S and S+1 is defined as mixing of two CPU steppings in the same platform where one
CPU is S (stepping) = CPUID.(EAX=01h):EAX[3:0], and the other is S+1 =
CPUID.(EAX=01h):EAX[3:0]+1. The stepping ID is found in EAX[3:0] after executing
the CPUID instruction with Function 01h.
Details regarding the CPUID instruction are provided in the AP-485, Intel® Processor
Identification and the CPUID Instruction application note. Also refer to the Intel®
Xeon® Processor E5 Prodcut Family Specification Update.
7.6
Flexible Motherboard Guidelines (FMB)
The Flexible Motherboard (FMB) guidelines are estimates of the maximum values the
processor will have over certain time periods. The values are only estimates and actual
specifications for future processors may differ. Processors may or may not have
specifications equal to the FMB value in the foreseeable future. System designers
should meet the FMB values to ensure their systems will be compatible with future
processors.
7.7
Absolute Maximum and Minimum Ratings
Table 7-9 specifies absolute maximum and minimum ratings. At conditions outside
functional operation condition limits, but within absolute maximum and minimum
ratings, neither functionality nor long-term reliability can be expected. If a device is
returned to conditions within functional operation limits after having been subjected to
conditions outside these limits, but within the absolute maximum and minimum
ratings, the device may be functional, but with its lifetime degraded depending on
exposure to conditions exceeding the functional operation condition limits.
Although the processor contains protective circuitry to resist damage from ElectroStatic Discharge (ESD), precautions should always be taken to avoid high static
voltages or electric fields.

Notes:
1.
For functional operation, all processor electrical, signal quality, mechanical, and thermal specifications must
be satisfied.
2.
Overshoot and undershoot voltage guidelines for input, output, and I/O signals are outlined in
Section 7.9.5. Excessive overshoot or undershoot on any signal will likely result in permanent damage to
the processor.
7.7.1
Storage Conditions Specifications
Environmental storage condition limits define the temperature and relative humidity
limits to which the device is exposed to while being stored in a Moisture Barrier Bag.
The specified storage conditions are for component level prior to board attach (see
notes in Table 7-10 for post board attach limits).
Table 7-10 specifies absolute maximum and minimum storage temperature limits which
represent the maximum or minimum device condition beyond which damage, latent or
otherwise, may occur. The table also specifies sustained storage temperature, relative
humidity, and time-duration limits. These limits specify the maximum or minimum
device storage conditions for a sustained period of time. At conditions outside sustained
limits, but within absolute maximum and minimum ratings, quality & reliability may be
affected.

Notes:
1.
Storage conditions are applicable to storage environments only. In this scenario, the processor must not
receive a clock, and no lands can be connected to a voltage bias. Storage within these limits will not affect
the long-term reliability of the device. For functional operation, please refer to the processor case
temperature specifications.
2.
These ratings apply to the Intel component and do not include the tray or packaging.
3.
Failure to adhere to this specification can affect the long-term reliability of the processor.
4.
Non-operating storage limits post board attach: Storage condition limits for the component once attached
to the application board are not specified. Intel does not conduct component level certification assessments
post board attach given the multitude of attach methods, socket types and board types used by customers.
Provided as general guidance only, Intel board products are specified and certified to meet the following
temperature and humidity limits (Non-Operating Temperature Limit: -40°C to 70°C & Humidity: 50% to
90%, non condensing with a maximum wet bulb of 28°C).
5.
Device storage temperature qualification methods follow JEDEC High and Low Temperature Storage Life
Standards: JESD22-A119 (low temperature) and JESD22-A103 (high temperature).

Notes:
1.
Unless otherwise noted, all specifications in this table apply to all processors. These specifications are based on final silicon
characterization.
2.
Individual processor VID values may be calibrated during manufacturing such that two devices at the same speed may have
different settings.
3.
These voltages are targets only. A variable voltage source should exist on systems in the event that a different voltage is
required.
4.
The VCC voltage specification requirements are measured across the remote sense pin pairs (VCC_SENSE and
VSS_VCC_SENSE) on the processor package. Voltage measurement should be taken with a DC to 100 MHz bandwidth
oscilloscope limit (or DC to 20 MHz for older model oscilloscopes), using a 1.5 pF maximum probe capacitance, and 1MΩ
minimum impedance. The maximum length of the ground wire on the probe should be less than 5 mm to ensure external
noise from the system is not coupled in the scope probe.
5.
The VTTA, and VTTD voltage specification requirements are measured across the remote sense pin pairs (VTTD_SENSE and
VSS_VTTD_SENSE) on the processor package. Voltage measurement should be taken with a DC to 100 MHz bandwidth
oscilloscope limit (or DC to 20 MHz for older model oscilloscopes), using a 1.5 pF maximum probe capacitance, and 1MΩ
minimum impedance. The maximum length of the ground wire on the probe should be less than 5 mm to ensure external
noise from the system is not coupled in the scope probe.
6.
The VSA voltage specification requirements are measured across the remote sense pin pairs (VSA_SENSE and
VSS_VSA_SENSE) on the processor package. Voltage measurement should be taken with a DC to 100 MHz bandwidth
oscilloscope limit (or DC to 20 MHz for older model oscilloscopes), using a 1.5 pF maximum probe capacitance, and 1MΩ
minimum impedance. The maximum length of the ground wire on the probe should be less than 5 mm to ensure external
noise from the system is not coupled in the scope probe.
7.
For the 8/6-core processor refer to Table 7-13 and corresponding Figure 7-3. For the 4/2-core processor refer to Table 7-14
and corresponding Figure 7-4.The processor should not be subjected to any static VCC level that exceeds the VCC_MAX
associated with any particular current. Failure to adhere to this specification can shorten processor lifetime.
8.
Minimum VCC and maximum ICC are specified at the maximum processor case temperature (TCASE) shown in Section 5,
“Thermal Management Specifications”. ICC_MAX is specified at the relative VCC_MAX point on the VCC load line. The processor is
capable of drawing ICC_MAX for up to 5 seconds. Refer to Figure 7-5 for further details on the average processor current draw
over various time durations.
9.
The processor should not be subjected to any static VTTA, VTTD level that exceeds the VTT_MAX associated with any particular
current. Failure to adhere to this specification can shorten processor lifetime.
10. This specification represents the VCC reduction or VCC increase due to each VID transition, see Section 7.1.9.3, “Voltage
Identification (VID)”.
11. Baseboard bandwidth is limited to 20 MHz.
12. FMB is the flexible motherboard guidelines. See Section 7.6 for FMB details.
13. DC + AC + Ripple = Total Tolerance
14. For Power State Functions see Section 7.1.9.3.5.
15. VSA_VID does not have a loadline, the output voltage is expected to be the VID value.

16. VCCD tolerance at processor pins. Tolerance for VR at remote sense is ±3.3%*VCCD.
17. The VCCPLL, VCCD01, VCCD23 voltage specification requirements are measured across vias on the platform. Choose VCCPLL,
VCCD01, or VCCD23 vias close to the socket and measure with a DC to 100 MHz bandwidth oscilloscope limit (or DC to 20 MHz
for older model oscilloscopes), using 1.5 pF maximum probe capacitance, and 1MΩ minimum impedance. The maximum
length of the ground wire on the probe should be less than 5 mm to ensure external noise from the system is not coupled in
the scope probe.
18. VCC has a Vboot setting of 0.0 V and is not included in the PWRGOOD indication. Refer to the VR12/IMVP7 Pulse Width
Modulation Specification.

Die Voltage Validation
Core voltage (VCC) overshoot events at the processor must meet the specifications in
Table 7-15 when measured across the VCC_SENSE and VSS_VCC_SENSE lands.
Overshoot events that are < 10 ns in duration may be ignored. These measurements of
processor die level overshoot should be taken with a 100 MHz bandwidth limited
oscilloscope.
Figure 7-5.
Load Current Versus Time
Notes:
1.
The peak current for any 5 second sample does not exceed Icc_max.
2.
The average current for any 10 second sample does not exceed the Y value at 10 seconds.
3.
The average current for any 20 second period or greater does not exceed Icc_tdc.
4.
Turbo performance may be impacted by failing to meet durations specified in this graph. Ensure that the
platform design can handle peak and average current based on the specification.
5.
Processor or voltage regulator thermal protection circuitry should not trip for load currents greater than
ICC_TDC.
6.
Not 100% tested. Specified by design characterization.
7.8.2.1
VCC Overshoot Specifications
The processor can tolerate short transient overshoot events where VCC exceeds the VID
voltage when transitioning from a high-to-low current load condition. This overshoot
cannot exceed VID + VOS_MAX (VOS_MAX is the maximum allowable overshoot above
VID). These specifications apply to the processor die voltage as measured across the
VCC_SENSE and VSS_VCC_SENSE lands.

3.
VIL is the maximum voltage level at a receiving agent that will be interpreted as a logical low value.
4.
VIH is the minimum voltage level at a receiving agent that will be interpreted as a logical high value.
5.
VIH and VOH may experience excursions above VCCD. However, input signal drivers must comply with the signal quality
specifications. Refer to Section 7.9.
6.
This is the pull down driver resistance. Refer to processor signal integrity models for I/V characteristics. Reset drive does not
have a termination.
7.
RVTT_TERM is the termination on the DIMM and not controlled by the processor. Please refer to the applicable DIMM datasheet.
8.
The minimum and maximum values for these signals are programmable by BIOS to one of the pairs.
9.
COMP resistance must be provided on the system board with 1% resistors. See the applicable platform design guide for
implementation details. DDR01_RCOMP[2:0] and DDR23_RCOMP[2:0] resistors are terminated to VSS.
10. Input leakage current is specified for all DDR3 signals.
11. DRAM_PWR_OK_C{01/23} must have a maximum of 30 ns rise or fall time over VCCD * 0.55 +300 mV and -200 mV and the
edge must be monotonic.
12. The DDR01/23_RCOMP error tolerance is ± 15% from the compensated value.

Notes:
1.
VTTD supplies the PECI interface. PECI behavior does not affect VTTD min/max specification
2.
It is expected that the PECI driver will take into account, the variance in the receiver input thresholds and consequently, be
able to drive its output within safe limits (-0.150 V to 0.275*VTTD for the low level and 0.725*VTTD to VTTD+0.150 V for the
high level).
3.
The leakage specification applies to powered devices on the PECI bus.
4.
One node is counted for each client and one node for the system host. Extended trace lengths might appear as additional
nodes.
5.
Excessive capacitive loading on the PECI line may slow down the signal rise/fall times and consequently limit the maximum bit
rate at which the interface can operate.

PWRGOOD Non Monotonicity duration (TNM) time is maximum 1.3 ns.
These are measured between VIL and VIH. If the edge rate specification is not met, make sure there is a monotonic edge and
the edge rate is not lower than the edge rate specification for the monotonic edges. The monotonic input edge rate is
0.02 V/ns.
The waveform could be non-monotonic when measured at the land (near the socket at the bottom side of via) but not when
observed at the pad during simulation. The waveform measured at the land could violate specifications defined at the pad.
Customers could measure the land timings on their boards and then use the package length information found in the Model
Usage Guidelines (MUG) which comes with the I/O model to correlate the results to the specification at the pad.

Signal Quality
Data transfer requires the clean reception of data signals and clock signals. Ringing
below receiver thresholds, non-monotonic signal edges, and excessive voltage swings
will adversely affect system timings. Ringback and signal non-monotonicity cannot be
tolerated since these phenomena may inadvertently advance receiver state machines.
Excessive signal swings (overshoot and undershoot) are detrimental to silicon gate
oxide integrity, and can cause device failure if absolute voltage limits are exceeded.
Overshoot and undershoot can also cause timing degradation due to the build up of
inter-symbol interference (ISI) effects.
For these reasons, it is crucial that the designer work towards a solution that provides
acceptable signal quality across all systematic variations encountered in volume
manufacturing.
This section documents signal quality metrics used to derive topology and routing
guidelines through simulation. All specifications are specified at the processor die (pad
measurements).
Specifications for signal quality are for measurements at the processor core only and
are only observable through simulation. Therefore, proper simulation is the only way to
verify proper timing and signal quality.
7.9.1
DDR3 Signal Quality Specifications
Various scenarios for the DDR3 Signals have been simulated to generate a set of layout
guidelines which are available in the appropriate Platform Design Guide (PDG).
Overshoot (or undershoot) is the absolute value of the maximum voltage above or
below VSS. The overshoot/undershoot specifications limit transitions beyond specified
maximum voltages or VSS due to the fast signal edge rates. The processor can be
damaged by single and/or repeated overshoot or undershoot events on any input,
output, or I/O buffer if the charge is large enough (i.e., if the over/undershoot is great
enough). Baseboard designs which meet signal integrity and timing requirements and
which do not exceed the maximum overshoot or undershoot limits listed in Table 7-24
will insure reliable IO performance for the lifetime of the processor.

I/O Signal Quality Specifications
Signal Quality specifications for PCIe* Signals are included as part of the PCIe* DC
specifications. Various scenarios have been simulated to generate a set of layout

7.9.4
Input Reference Clock Signal Quality Specifications
Overshoot/Undershoot and Ringback specifications for BCLK{0/1}_D[N/P] are found in
Table 7-24. Overshoot/Undershoot and Ringback specifications for the DDR3 Reference
Clocks are specified by the DIMM.
7.9.5
Overshoot/Undershoot Tolerance
Overshoot (or undershoot) is the absolute value of the maximum voltage above or
below VSS, see Figure 7-11. The overshoot/undershoot specifications limit transitions
beyond VCCD or VSS due to the fast signal edge rates. The processor can be damaged
by single and/or repeated overshoot or undershoot events on any input, output, or I/O
buffer if the charge is large enough (that is, if the over/undershoot is great enough).
Determining the impact of an overshoot/undershoot condition requires knowledge of
the magnitude, the pulse direction, and the activity factor (AF). Permanent damage to
the processor is the likely result of excessive overshoot/undershoot.
Baseboard designs which meet signal integrity and timing requirements and which do
not exceed the maximum overshoot or undershoot limits listed in Table 7-24 will insure
reliable IO performance for the lifetime of the processor.

7.9.5.1
Overshoot/Undershoot Magnitude
Overshoot/Undershoot magnitude describes the maximum potential difference between
a signal and its voltage reference level. For the processor, both overshoot and
undershoot magnitude are referenced to VSS. It is important to note that the overshoot
and undershoot conditions are separate and their impact must be determined
independently.
The pulse magnitude and duration, and activity factor must be used to determine if the
overshoot/undershoot pulse is within specifications.

Datasheet Volume One
7.9.5.2
Overshoot/Undershoot Pulse Duration
Overshoot/undershoot pulse duration describes the total amount of time that an
overshoot/undershoot event exceeds the overshoot/undershoot reference voltage. The
total time could encompass several oscillations above the reference voltage. Multiple
overshoot/undershoot pulses within a single overshoot/undershoot event may need to
be measured to determine the total pulse duration.
Note:
Oscillations below the reference voltage cannot be subtracted from the total overshoot/
undershoot pulse duration.
7.9.5.3
Activity Factor
Activity factor (AF) describes the frequency of overshoot (or undershoot) occurrence
relative to a clock. Since the highest frequency of assertion of any common clock signal
is every other clock, an AF = 0.1 indicates that the specific overshoot (or undershoot)
waveform occurs every other clock cycle.
The specification provided in the table shows the maximum pulse duration allowed for a
given overshoot/undershoot magnitude at a specific activity factor. Each table entry is
independent of all others, meaning that the pulse duration reflects the existence of
overshoot/undershoot events of that magnitude ONLY. A platform with an overshoot/
undershoot that just meets the pulse duration for a specific magnitude where the AF <
0.1, means that there can be no other overshoot/undershoot events, even of lesser
magnitude (note that if AF = 0.1, then the event occurs at all times and no other
events can occur).
7.9.5.4
Reading Overshoot/Undershoot Specification Tables
The overshoot/undershoot specification for the processor is not a simple single value.
Instead, many factors are needed to determine the over/undershoot specification. In
addition to the magnitude of the overshoot, the following parameters must also be
known: the width of the overshoot and the activity factor (AF). To determine the
allowed overshoot for a particular overshoot event, the following must be done:
1. Determine the signal group a particular signal falls into.
2. Determine the magnitude of the overshoot or the undershoot (relative to VSS).
3. Determine the activity factor (How often does this overshoot occur?).
4. Next, from the appropriate specification table, determine the maximum pulse
duration (in nanoseconds) allowed.
5. Compare the specified maximum pulse duration to the signal being measured. If
the pulse duration measured is less than the pulse duration shown in the table,
then the signal meets the specifications.
Undershoot events must be analyzed separately from overshoot events as they are
mutually exclusive.
7.9.5.5
Determining if a System Meets the Overshoot/Undershoot
Specifications
The overshoot/undershoot specifications listed in the table specify the allowable
overshoot/undershoot for a single overshoot/undershoot event. However most systems
will have multiple overshoot and/or undershoot events that each have their own set of
parameters (duration, AF and magnitude). While each overshoot on its own may meet
Intel® Xeon® Processor E5-1600/E5-2600/E5-4600 Product Families
Datasheet Volume One
185
the overshoot specification, when you add the total impact of all overshoot events, the
system may fail. A guideline to ensure a system passes the overshoot and undershoot
specifications is shown below.
1. If only one overshoot/undershoot event magnitude occurs, ensure it meets the
over/undershoot specifications in the following tables, OR
2. If multiple overshoots and/or multiple undershoots occur, measure the worst case
pulse duration for each magnitude and compare the results against the AF = 0.1
specifications. If all of these worst case overshoot or undershoot events meet the
specifications (measured time < specifications) in the table (where AF= 0.1), then
the system passes.

Processor Component Keep-Out Zones
The processor may contain components on the substrate that define component
keep-out zone requirements. A thermal and mechanical solution design must not
intrude into the required keep-out zones. Do not contact the Test Pad Area with
conductive material. Decoupling capacitors are typically mounted to either the topside
or land-side of the package substrate. See Figure 9-2 and Figure 9-3 for keep-out
zones. The location and quantity of package capacitors may change due to
manufacturing efficiencies but will remain within the component keep-in.
9.3
Package Loading Specifications
Table 9-1 provides load specifications for the processor package. These maximum
limits should not be exceeded during heatsink assembly, shipping conditions, or
standard use condition. Exceeding these limits during test may result in component
failure. The processor substrate should not be used as a mechanical reference or loadbearing surface for thermal solutions.

Boxed Processor Specifications
10.1
Introduction
Intel boxed processors are intended for system integrators who build systems from
components available through distribution channels. The Intel® Xeon® processor E52600 product family (LGA2011-0 land FCLGA10) processors will be offered as Intel
boxed processors, however the thermal solutions will be sold separately.
Boxed processors will not include a thermal solution in the box. Intel will offer boxed
thermal solutions separately through the same distribution channels. Please reference
Section 10.1.1 - Section 10.1.3 for a description of Boxed Processor thermal solutions.
10.1.1
Available Boxed Thermal Solution Configurations
Intel will offer three different Boxed Heat Sink solutions to support LGA2011-0 land
FCLGA10 Boxed Processors
• Boxed Intel® Thermal Solution STS200C (Order Code BXSTS200C): A Passive /
Active Combination Heat Sink Solution that is intended for processors with a TDP
up to 150W in a pedestal or 130W in 2U+ chassis with appropriate ducting.
• Boxed Intel® Thermal Solution STS200P (Order Code BXSTS200P): A 25.5 mm Tall
Passive Heat Sink Solution that is intended for processors with a TDP of 130W or
lower in 1U, or 2U chassis with appropriate ducting. Check with Blade manufacturer
for compatibility.
• Boxed Intel® Thermal Solution STS200PNRW (Order Code BXSTS200PNRW): A
25.5 mm Tall Passive Heat Sink Solution that is intended for processors with a TDP
of 130W or lower in 1U, or 2U chassis with appropriate ducting. Compatible with
the narrow processor integrated load mechanism. Check with Blade manufacturer
for compatibility.
10.1.2
Intel Thermal Solution STS200C
(Passive/Active Combination Heat Sink Solution)
The STS200C, based on a 2U passive heat sink with a removable fan, is intended for
use with processors with TDP’s up to 150W in active configuration and 130W in passive
configuration. This heat pipe-based solution is intended to be used as either a passive
heat sink in a 2U or larger chassis, or as an active heat sink for pedestal chassis.
Figure 10-1 and Figure 10-2 are representations of the heat sink solution. Although the
active combination solution with the removable fan installed mechanically fits into a 2U
keepout, its use has not been validated in that configuration.
The STS200C in the active fan configuration is primarily designed to be used in a
pedestal chassis where sufficient air inlet space is present. The STS200C with the fan
removed, as with any passive thermal solution, will require the use of chassis ducting
and are targeted for use in rack mount or ducted pedestal servers. The retention
solution used for these products is called ILM Retention System (ILM-RS).

Boxed Processor Specifications
Figure 10-1. STS200C Passive/Active Combination Heat Sink (with Removable Fan)
Figure 10-2. STS200C Passive/Active Combination Heat Sink (with Fan Removed)
The STS200C utilizes a fan capable of 4-pin pulse width modulated (PWM) control. Use
of a 4-pin PWM controlled active thermal solution helps customers meet acoustic
targets in pedestal platforms through the baseboard’s ability to directly control the RPM
of the processor heat sink fan. See Section 10.3 for more details on fan speed control.
Also see Section 2.5, “Platform Environment Control Interface (PECI)” for more on the
PWM and PECI interface along with Digital Thermal Sensors (DTS).
10.1.3
Intel Thermal Solution STS200P and STS200PNRW
(Boxed 25.5 mm Tall Passive Heat Sink Solutions)
The STS200P and STS200PNRW are available for use with boxed processors that have
TDP’s of 130W and lower. These 25.5 mm Tall passive solutions are designed to be used
in SSI Blades, 1U, and 2U chassis where ducting is present. The use of a 25.5 mm Tall
heatsink in a 2U chassis is recommended to achieve a lower heatsink TLA and more
flexibility in system design optimization. Figure 10-3 is a representation of the heat

sink solutions. The retention solution used for the STS200P Heat Sink Solution is called
the ILM Retention System (ILM-RS).The retention solution used for the STS200PNRW
Narrow Heat Sink Solution is called the Narrow ILM Retention System (Narrow ILM-RS).

10.2
Mechanical Specifications
This section documents the mechanical specifications of the boxed processor solution.
10.2.1
Boxed Processor Heat Sink Dimensions and Baseboard
Keepout Zones
The boxed processor and boxed thermal solutions will be sold separately. Clearance is
required around the thermal solution to ensure unimpeded airflow for proper cooling.
Baseboard keepout zones are Figure 10-4 - Figure 10-7. Physical space requirements
and dimensions for the boxed processor and assembled heat sink are shown in
Figure 10-8 and Figure 10-9. Mechanical drawings for the 4-pin fan header and 4-pin
connector used for the active fan heat sink solution are represented in Figure 10-10
and Figure 10-11.
None of the heat sink solutions exceed a mass of 550 grams. Note that this is per
processor, a dual processor system will have up to 1100 grams total mass in the heat
sinks. See Section 9.6 for details on the processor mass test.

10.2.2
Boxed Processor Retention Mechanism and Heat Sink
Support (ILM-RS)
Baseboards designed for use by a system integrator should include holes that are in
proper alignment with each other to support the boxed processor.
The standard and narrow ILM-RSs are designed to extend air-cooling capability through
the use of larger heat sinks with minimal airflow blockage and bypass. ILM-RS
retention transfers load to the baseboard via the ILM Assembly. The ILM-RS spring,
captive in the heatsink, provides the necessary compressive load for the thermal
interface material. For specific design details on the standard and narrow ILM-RS and
the Backplate please refer to the Intel® Xeon® Processor E5-1600/E5-2600/E5-4600
Product Families Thermal/Mechanical Design Guide.
All components of the ILM-RS heat sink solution will be captive to the heat sink and will
only require a Phillips screwdriver to attach to the ILM Backplate Assembly. When
installing the ILM-RS the screws should be tightened until they will no longer turn
easily. This should represent approximately 8 inch-pounds of torque. More than that
may damage the retention mechanism components.
10.3
Fan Power Supply [STS200C]
The 4-pin PWM controlled thermal solution is being offered to help provide better
control over pedestal chassis acoustics. This is achieved through more accurate
measurement of processor die temperature through the processor’s Digital Thermal
Sensors. Fan RPM is modulated through the use of an ASIC located on the baseboard
that sends out a PWM control signal to the 4th pin of the connector labeled as Control.
This thermal solution requires a constant +12 V supplied to pin 2 of the active thermal
solution and does not support variable voltage control or 3-pin PWM control. See
Figure 10-12 and Table 10-1 for details on the 4-pin active heat sink solution
connectors.
The fan power header on the baseboard must be positioned to allow the fan heat sink
power cable to reach it. The fan power header identification and location must be
documented in the suppliers platform documentation, or on the baseboard itself. The
baseboard fan power header should be positioned within 177.8 mm [7 in.] from the
center of the processor socket.

10.3.1
Boxed Processor Cooling Requirements
As previously stated the boxed processor will have three thermal solutions available.
Each configuration will require unique design considerations. Meeting the processor’s
temperature specifications is also the function of the thermal design of the entire
system, and ultimately the responsibility of the system integrator. The processor
temperature specifications are found in Section 5, “Thermal Management
Specifications” of this document.
10.3.1.1
STS200C (Passive / Active Combination Heat Sink Solution)
The active configuration of the combination solution is designed to help pedestal
chassis users to meet the thermal processor requirements without the use of processor
chassis ducting. However, it is strongly recommended to implement some form of air
duct to meet memory cooling and processor TLA temperature requirements. Use of the
active configuration in a 2U rackmount chassis is not recommended.
In the passive configuration it is assumed that a chassis duct will be implemented.
For a list processor and thermal solution boundary conditions, such as Psica, TLA,
airflow, flow impedance, etc, see Table 10-2 and Table 10-3. It is recommended that
the ambient air temperature outside of the chassis be kept at or below 35 °C. Meeting
the processor’s temperature specification is the responsibility of the system
integrator.This thermal solution is for use with processor SKUs no higher than 150W (8
Core) or 130W (4 and 6 core).
10.3.1.2
STS200P and STS200PNRW (25.5mm Tall Passive Heat Sink Solution)
(Blade + 1U + 2U Rack)
These passive solutions are intended for use in SSI Blade, 1U or 2U rack configurations.
It is assumed that a chassis duct will be implemented in all configurations.
For a list processor and thermal solution boundary conditions, such as Psica, TLA,
airflow, flow impedance, etc, see Table 10-2 and Table 10-3. It is recommended that
the ambient air temperature outside of the chassis be kept at or below 35 °C. Meeting
the processor’s temperature specification is the responsibility of the system integrator.
These thermal solutions are for use with processor SKUs no higher than 130W (6 and 8
Core), or 80W (4 Core).
