Terminology
A ‘#’ symbol after a signal name refers to an active low signal, indicating a signal is in
the active state when driven to a low level. For example, when RESET# is low, a reset
has been requested.
A ‘_N’ and ‘_P’ after a signal name refers to a differential pair.
Commonly used terms are explained here for clarification:
• 1366-land FC-LGA package — The Intel Xeon processor 5500 series is available
in a Flip-Chip Land Grid Array (FC-LGA) package, consisting of processor mounted
on a land grid array substrate with an integrated heat spreader (IHS).
• DDR3 — Double Data Rate 3 synchronous dynamic random access memory
(SDRAM) is the name of the new DDR memory standard that is being developed as
the successor to DDR2 SDRAM.
• Enhanced Intel SpeedStep Technology — Enhanced Intel SpeedStep
Technology allows the operating system to reduce power consumption when
performance is not needed.
• Intel Turbo Boost Technology — Intel Turbo Boost Technology is a way to
automatically run the processor core faster than the marked frequency if the part is
operating under power, temperature, and current specifications limits of the
Thermal Design Power (TDP). This results in increased performance of both single
and multi-threaded applications.
• Execute Disable Bit — Execute Disable allows memory to be marked as
executable or non-executable, 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 over run vulnerabilities and can thus help improve the overall
security of the system. See the Intel® 64 and IA-32 Architecture Software
Developer's Manuals for more detailed information.
• Functional Operation — Refers to the normal operating conditions in which all
processor specifications, including DC, AC, signal quality, mechanical, and thermal,
are satisfied.

Intel® Xeon® Processor 5500 Series Datasheet, Volume 1
Introduction
• Intel Xeon Processor 5500 Series — Includes processor substrate and
integrated heat spreader (IHS).
• Integrated Memory Controller (IMC) — As the term implies, the Memory
Controller is integrated on the processor die.
• Intel QuickPath Interconnect (Intel® QPI) — A cache-coherent, link-based
Interconnect specification for Intel processors, chipsets, and I/O bridge
components.
• Intel® 64 Architecture — An enhancement to Intel's IA-32 architecture, allowing
the processor to execute operating systems and applications written to take
advantage of Intel® 64.
• Intel Virtualization Technology (Intel® VT) — A set of hardware
enhancements to Intel server and client platforms that can improve virtualization
solutions. VT provides a foundation for widely-deployed virtualization solutions and
enables more robust hardware assisted virtualization solution.
• Integrated Heat Spreader (IHS) — A component of the processor package used
to enhance the thermal performance of the package. Component thermal solutions
interface with the processor at the IHS surface.
• Jitter — Any timing variation of a transition edge or edges from the defined Unit
Interval (UI).
• LGA1366 Socket — The 1366-land FC-LGA package mates with the system board
through this surface mount, 1366-contact socket.
• Server SKU — A processor Stock Keeping Unit (SKU) to be installed in either
server or workstation platforms. Electrical, power and thermal specifications for
these SKU’s are based on specific use condition assumptions. Server processors
may be further categorized as Advanced, Standard/Basic, and Low Power SKUs. For
further details on use condition assumptions, please refer to the latest Product
Release Qualification (PRQ) Report available via your Customer Quality Engineer
(CQE) contact.
• Storage Conditions — Refers to a non-operational state. The processor may be
installed in a platform, in a tray, or loose. Processors may be sealed in packaging or
exposed to free air. Under these conditions, processor lands should not be
connected to any supply voltages, have any I/Os biased, or receive any clocks.
• Unit Interval (UI) — Signaling convention that is binary and unidirectional. In
this binary signaling, one bit is sent for every edge of the forwarded clock, whether
it be a rising edge or a falling edge. If a number of edges are collected at instances
t1, t2, tn,...., tk then the UI at instance “n” is defined as:
UI
n
=t
n
-t
n-1
• Workstation SKU — A processor SKU to be installed in workstation platforms
only. Electrical, power and thermal specifications for these processors have been
developed based on Intel’s reliability goals at a reference use condition. In addition,
the processor validation and production test conditions have been optimized based
on these conditions. Operating “Workstation” processors in a server environment or
other application, could impact reliability performance, which means Intel’s
reliability goals may not be met. For further details on use condition assumptions or
reliability performance, please refer to the latest Product Release Qualification
(PRQ) Report available via your Customer Quality Engineer (CQE) contact.
• NEBS — Network Equipment Building System. NEBS is the most common set of
environmental design guidelines applied to telecommunications equipment in the
United States.

Processor Signaling
Intel Xeon processor 5500 series include 1366 lands, which utilize various signaling
technologies. Signals are grouped by electrical characteristics and buffer type into
various signal groups. These include Intel QuickPath Interconnect, DDR3 (Reference
Clock, Command, Control and Data), Platform Environmental Control Interface (PECI),
Processor Sideband, System Reference Clock, Test Access Port (TAP), and Power/Other
signals. Refer to Table 2-5 for details.
Detailed layout, routing, and termination guidelines corresponding to these signal
groups can be found in the applicable platform design guide (Refer to Section 1.2).
Intel strongly recommends performing analog simulations of all interfaces. Please refer
to Section 1.2 for signal integrity model availability.
2.1.1
Intel® QuickPath Interconnect
Intel Xeon processor 5500 series provide two Intel QuickPath Interconnect ports for
high speed serial transfer between other enabled components. Each port consists of
two uni-directional links (for transmit and receive). A differential signaling scheme is
utilized, which consists of opposite-polarity (D_P, D_N) signal pairs.
On-die termination (ODT) is included on the processor silicon and terminated to VSS.
Intel chipsets also provide ODT, thus eliminating the need to terminate on the system
board. Figure 2-1 illustrates the active ODT.

DDR3 Signal Groups
The memory interface utilizes DDR3 technology, which consists of numerous signal
groups. These include: Reference Clocks, Command Signals, Control Signals, and Data
Signals. Each group consists of numerous signals, which may utilize various signaling
technologies. Please refer to Table 2-5 for further details.

Intel® Xeon® Processors 5500 Series Electrical Specifications
2.1.3
Platform Environmental Control Interface (PECI)
PECI is an Intel proprietary interface that provides a communication channel between
Intel processors and chipset components to external thermal monitoring devices. The
Intel Xeon Processor 5500 Series contains a Digital Thermal Sensor (DTS) that reports
a relative die temperature as an offset from Thermal Control Circuit (TCC) activation
temperature. Temperature sensors located throughout the die are implemented as
analog-to-digital converters calibrated at the factory. PECI provides an interface for
external devices to read processor temperature, perform processor manageability
functions, and manage processor interface tuning and diagnostics. Please refer to
Section 6 for processor specific implementation details for PECI.
The PECI interface operates at a nominal voltage set by VTTD. The set of DC electrical
specifications shown in Table 2-13 is used with devices normally operating from a VTTD
interface supply.
2.1.3.1
Input Device Hysteresis
The PECI client and host input buffers must use a Schmitt-triggered input design for
improved noise immunity. Please refer to Figure 2-2 and Table 2-13.

Processor Sideband Signals
Intel Xeon processor 5500 series include sideband signals that provide a variety of
functions. Details can be found in Table 2-5 and the applicable platform design guide.
All Asynchronous Processor Sideband signals are required to be asserted/deasserted
for at least eight BCLKs in order for the processor to recognize the proper signal state.
See Table 2-17 for DC specifications.
2.1.5
System Reference Clock
The processor core, processor uncore, Intel QuickPath Interconnect link, and DDR3
memory interface frequencies are generated from BCLK_DP and BCLK_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
14
Intel® Xeon® Processor 5500 Series Datasheet, Volume 1
Intel® Xeon® Processors 5500 Series Electrical Specifications
and DDR3 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.
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.
Clock multiplying within the processor is provided by the internal phase locked loop
(PLL), which requires a constant frequency BCLK_DP, BCLK_DN input, with exceptions
for spread spectrum clocking.
2.1.6
Test Access Port (TAP) Signals
Due to the voltage levels supported by other components in the Test Access Port (TAP)
logic, it is recommended that the processor(s) be first in the TAP chain and followed by
any other components within the system. 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. Similar considerations must be made for
TCK, TDO, TMS, and TRST#. Two copies of each signal may be required with each
driving a different voltage level.
Processor TAP signal DC specifications can be found in Table 2-17.
Note:
While TDI, TMS and TRST# do not include On-Die Termination (ODT), these signals are
weakly pulled-up via a 1-5 kΩ resistor to VTT.
Note:
While TCK does not include ODT, this signal is weakly pulled-down via a 1-5 kΩ resistor
to VSS.
2.1.7
Power / Other Signals
Processors also include various other signals including power/ground, sense points, and
analog inputs. Details can be found in Table 2-5 and the applicable platform design
guide.
Table 2-1 outlines the required voltage supplies necessary to support Intel Xeon
processor 5500 series.

2.1.7.1
Power and Ground Lands
For clean on-chip power distribution, processors include lands for all required voltage
supplies. These include:
• 210 each VCC (271 ea. VSS) lands must be supplied with the voltage determined by
the VID[7:0] signals. Table 2-2 defines the voltage level associated with each core
VID pattern. Table 2-9 and Figure 2-3 represent VCC static and transient limits.
• 3 each VCCPLL lands, connected to a 1.8 V supply, power the Phase Lock Loop (PLL)
clock generation circuitry. An on-die PLL filter solution is implemented within the
Intel Xeon processor 5500 series.
• 45 each VDDQ (17 ea. VSS) lands, connected to a 1.50 V supply, provide power to
the processor DDR3 interface. This supply also powers the DDR3 memory
subsystem.
• 7 each VTTA (5 ea. VSS) and 26 ea. VTTD (17 ea. VSS) lands must be supplied with
the voltage determined by the VTT_VID[4:2] signals. Coupled with a 20 mV offset,
this corresponds to a VTT_VID pattern of ‘010xxx10’. Table 2-4 specifies the
voltage levels associated with each VTT_VID pattern. Table 2-11 and Figure 2-10
represent VTT static and transient limits.
All VCC, VCCPLL, VDDQ, 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 Intel® Xeon® Processor 5500 Platform Design Guide (PDG) for
decoupling, voltage plane and routing guidelines for each power supply voltage.
2.1.7.2
Decoupling Guidelines
Due to its large number of transistors and high internal clock speeds, the Intel Xeon
processor 5500 series 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. Larger bulk storage (CBULK), such
as electrolytic capacitors, supply current during longer lasting changes in current
demand, for example coming out of an idle condition. Similarly, they act as a storage
well for current when entering an idle condition from a running condition. Care must be
taken in the baseboard design to ensure that the voltages provided to the processor
remains within the specifications listed in Table 2-8. Failure to do so can result in timing
violations or reduced lifetime of the processor.
2.1.7.3
Processor VCC Voltage Identification (VID) Signals
The voltage set by the VID signals is the maximum reference voltage regulator (VR)
output to be delivered to the processor VCC lands. VID signals are CMOS push/pull
outputs. Please refer to Table 2-17 for the DC specifications for these and other
processor sideband signals.
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 Intel Xeon processor 5500 series uses eight voltage identification signals,
VID[7:0], to support automatic selection of core power supply voltages. Table 2-2
specifies the voltage level corresponding to the state of VID[7:0]. A ‘1’ in this table
refers to a high voltage level and a ‘0’ refers to a low voltage level. If the processor
socket is empty (SKTOCC# high), or the voltage regulation circuit cannot supply the
voltage that is requested, the voltage regulator must disable itself.
16
Intel® Xeon® Processor 5500 Series Datasheet, Volume 1
Intel® Xeon® Processors 5500 Series Electrical Specifications
The Intel Xeon processor 5500 series provides the ability to operate while transitioning
to an adjacent VID and its associated processor core voltage (VCC). This is represented
by a DC shift in the loadline. 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 core voltage. Transitions above the maximum specified VID are not permitted.
Table 2-8 includes VID step sizes and DC shift ranges. Minimum and maximum voltages
must be maintained as shown in Table 2-9.
The VRM or EVRD utilized must be capable of regulating its output to the value defined
by the new VID. DC specifications for dynamic VID transitions are included in Table 2-8
and Table 2-9.
Power source characteristics must be guaranteed to be stable whenever the supply to
the voltage regulator is stable.

Notes:
1.
When the “11111111” VID pattern is observed, or when the SKTOCC# pin is high, the voltage regulator
output should be disabled.
2.
Shading denotes the expected VID range of the Intel Xeon processor 5500 series.
3.
The VID range includes VID transitions that may be initiated by thermal events, Extended HALT state
transitions (see Section 7.2), higher C-States (see Section 7.2) or Enhanced Intel SpeedStep® Technology
transitions (see Section 7.5). The Extended HALT state must be enabled for the processor to
remain within its specifications.
4.
Once the VRM/EVRD is operating after power-up, if either the Output Enable signal is de-asserted or a
specific VID off code is received, the VRM/EVRD must turn off its output (the output should go to high
impedance) within 500 ms and latch off until power is cycled.
2.1.7.3.1
Power-On Configuration (POC) Logic
VID[7:0] signals also serve a second function. During power-up, Power-On
Configuration POC[7:0] functionality is multiplexed onto these signals via 1-5 kΩ pullup or pull down resistors located on the baseboard. These values provide voltage
regulator keying (VID[7]), inform the processor of the platforms power delivery
capabilities (MSID[2:0]), and program the gain applied to the ISENSE input
(CSC[2:0]). Table 2-3 maps VID signals to the corresponding POC functionality.

MSID[2:0] signals are provided
to indicate the Market Segment
for the processor and may be

compatibility or keying. See
Figure 7-1 for platform timing
requirements of the MSID[2:0]

Notes:
1. This setting is defined for future use; no specific Intel Xeon processor 5500 series SKU is defined with ICC_MAX
= 50A
2. General rule: Set PWM IMON slope to: 900 mV=IMAX, where IMAX =IccMAX with one exception: for Intel Xeon
Processor W5580 set IMON slope to 900 mV=180A, but for all other SKUs they have to match, as shown
above. Consult your PWM data sheet for the IMON slope setting.
Some POC signals include specific timing requirements. Please refer to Section 7.1 for
further details.
2.1.7.4
Processor VTT Voltage Identification (VTT_VID) Signals
The voltage set by the VTT_VID signals is the typical reference voltage regulator (VR)
output to be delivered to the processor VTTA and VTTD lands. It is expected that one
regulator will supply all VTTA and VTTD lands. VTT_VID signals are CMOS push/pull
outputs. Please refer to Table 2-17 for the DC specifications for these signals.
Individual processor VTT_VID values may be calibrated during manufacturing such that
two processor units with the same core frequency may have different default VTT_VID
settings.
The Intel Xeon processor 5500 series utilizes three voltage identification signals to
support automatic selection of power supply voltages. These correspond to
VTT_VID[4:2]. The VTT voltage level delivered to the processor lands must also
encompass a 20 mV offset (See Table 2-4; VTT_TYP) above the voltage level
corresponding to the state of the VTT_VID[7:0] signals (See Table 2-4; VR 11.0
Voltage). Table 2-11 and Figure 2-10 provide the resulting static and transient
tolerances. Please note that the maximum and minimum electrical loadlines are defined
by a 31.5 mV tolerance band above and below VTT_TYP values.
Power source characteristics must be guaranteed to be stable whenever the supply to
the voltage regulator is stable.

Reserved or Unused Signals
All Reserved (RSVD) signals must remain unconnected. Connection of these signals to
VCC, VTTA, VTTD, VDDQ, VSS, or any other signal (including each other) can result in
component malfunction or incompatibility with future processors. See Section 4 for the
land listing and the location of all Reserved signals.
For reliable operation, connect unused inputs or bidirectional signals to an appropriate
signal level. Unused Intel QuickPath Interconnect input and output pins can be left
floating. Unused active high inputs should be connected through a resistor to ground
(VSS). Unused outputs can be left unconnected; however, this may interfere with some
TAP functions, complicate debug probing, and prevent boundary scan testing. A resistor
must be used when tying bidirectional signals to power or ground. When tying any
signal to power or ground, including 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.
TAP signals do not include on-die termination, however they may include resistors on
package (refer to Section 2.1.6 for details). Inputs and utilized outputs must be
terminated on the baseboard. Unused outputs may be terminated on the baseboard or
left unconnected. Note that leaving unused outputs unterminated may interfere with
some TAP functions, complicate debug probing, and prevent boundary scan testing.

Mixing Processors
Intel supports dual processor (DP) configurations consisting of processors:
1. from the same power optimization segment
2. that support the same maximum Intel QuickPath Interconnect and DDR3 memory
speeds
3. that share symmetry across physical packages with respect to the number of
logical processor per package, number of cores per package, number of Intel
QuickPath interfaces, and cache topology
4. that have identical Extended Family, Extended Model, Processor Type, Family Code
and Model Number as indicated by the function 1 of the CPUID instruction
Note:
Processors must operate with the same Intel QuickPath Interconnect, DDR3 memory,
and core frequency.
While Intel does nothing to prevent processors from operating together, some
combinations may not be supported due to limited validation, which may result in
uncharacterized errata. Coupling this fact with the large number of Intel Xeon
processor 5500 series attributes, the following population rules and stepping matrix
have been developed to clearly define supported configurations.
1. Processors must be of the same power-optimization segment. This insures
processors include the same maximum Intel QuickPath Interconnect and DDR3
operating speeds and cache sizes.
Intel® Xeon® Processor 5500 Series Datasheet, Volume 1
25
Intel® Xeon® Processors 5500 Series Electrical Specifications
2. Processors must operate at the same core frequency. Note, processors within the
same power-optimization segment supporting different maximum core frequencies
(for example, a 2.93 GHz / 95 W and 2.66 GHz / 95 W) can be operated within a
system. However, both must operate at the highest frequency rating commonly
supported. Mixing components operating at different internal clock frequencies is
not supported and will not be validated by Intel.
3. Processors must share symmetry across physical packages with respect to the
number of logical processors per package, number of cores per package (but not
necessarily the same subset of cores within the packages), number of Intel
QuickPath Interconnect interfaces, and cache topology.
4. Mixing dissimilar steppings is only supported with processors that have identical
Extended Family, Extended Model, Processor Type, Family Code and Model Number
as indicated by the function 1 of the CPUID instruction. Mixing processors of
different steppings but the same model (as per CPUID instruction) is supported.
Details regarding the CPUID instruction are provided in the AP-485,
Intel® Processor Identification and the CPUID Instruction application note and the
Intel® 64 and IA-32 Architectures Software Developer’s Manual, Volume 2A.
5. After AND’ing the feature flag and extended feature flags from the installed
processors, any processor whose set of feature flags exactly matches the AND’ed
feature flags can be selected by the BIOS as the BSP. If no processor exactly
matches the AND’ed feature flag values, then the processor with the numerically
lower CPUID should be selected as the BSP.
6. Intel requires that the proper microcode update be loaded on each processor
operating within the system. Any processor that does not have the proper
microcode update loaded is considered by Intel to be operating out of specification.
7. Customers are fully responsible for the validation of their system configuration.
2.4
Flexible Motherboard Guidelines (FMB)
The Flexible Motherboard (FMB) guidelines are estimates of the maximum values the
Intel Xeon processor 5500 series 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 Intel Xeon processor 5500 series.
2.5
Absolute Maximum and Minimum Ratings
Table 2-7 specifies absolute maximum and minimum ratings which lie outside the
functional limits of the processor. Only within specified operation limits, can
functionality and long-term reliability be expected.
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.

Intel® Xeon® Processor 5500 Series Datasheet, Volume 1
Intel® Xeon® Processors 5500 Series Electrical Specifications
At conditions exceeding absolute maximum and minimum ratings, neither functionality
nor long-term reliability can be expected. Moreover, if a device is subjected to these
conditions for any length of time then, when returned to conditions within the
functional operating condition limits, it will either not function or its reliability will be
severely degraded.
Although the processor contains protective circuitry to resist damage from static
electric discharge, precautions should always be taken to avoid high static voltages or
electric fields.

Notes:
1. Unless otherwise noted, all specifications in this table apply to all processors. These specifications are based
on pre-silicon characterization and will be updated as further data becomes available.
2. Individual processor VID and/or VTT_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 vias on the platform for the VCCSENSE and
VSSSENSE pins close to the socket with a 100 MHz bandwidth oscilloscope, 1.5 pF maximum probe
capacitance, and 1 MΩ minimum impedance. The maximum length of ground wire on the probe should be
less than 5 mm. Ensure external noise from the system is not coupled in the scope probe.
5. The VTT voltage specification requirements are measured across vias on the platform for the VTTD_SENSE
and VSS_SENSE_VTTD lands close to the socket with a 100 MHz bandwidth oscilloscope, 1.5 pF maximum
probe capacitance, and 1 MΩ minimum impedance. The maximum length of ground wire on the probe should
be less than 5 mm. Ensure external noise from the system is not coupled in the scope probe.
6. Refer to Table 2-9 and corresponding Figure 2-3. 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.
7. Minimum VCC and maximum ICC are specified at the maximum processor case temperature (TCASE) shown in
Table 6-1. ICC_MAX is specified at the relative VCC_MAX point on the VCC load line. The processor is capable of
Intel® Xeon® Processor 5500 Series Datasheet, Volume 1
29
Intel® Xeon® Processors 5500 Series Electrical Specifications
drawing ICC_MAX for up to 10 ms. Refer to Figure 2-5 through Figure 2-8 for further details on the average
processor current draw over various time durations.
8. Refer to Table 2-11 and corresponding Figure 2-10. The processor should not be subjected to any static VTT
level that exceeds the VTT_MAX associated with any particular current. Failure to adhere to this specification
can shorten processor lifetime.
9. This specification represents the VCC reduction due to each VID transition. See Section 2.1.7.3.
10.Baseboard bandwidth is limited to 20 MHz.
11.FMB is the flexible motherboard guidelines. See Section 2.4 for FMB details.
12.ICC_TDC (Thermal Design Current) is the sustained (DC equivalent) current that the processor is capable of
drawing indefinitely and should be used for the voltage regulator temperature assessment. The voltage
regulator is responsible for monitoring its temperature and asserting the necessary signal to inform the
processor of a thermal excursion.
13.Specification is at TCASE = 50°C.
14.Characterized by design (not tested).

VCC Overshoot Specifications
The Intel Xeon Processor 5500 Series 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_SENSE lands.

Note:
1.
VTTD supplies the PECI interface. PECI behavior does not affect VTTD min/max specifications.
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 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.
6.
Please refer to Figure 2-2 for further information.

3.1
Package Mechanical Specifications
The processor is packaged in a Flip-Chip Land Grid Array (FC-LGA6) package that
interfaces with the motherboard via an LGA1366 socket. The package consists of a
processor mounted on a substrate land-carrier. An integrated heat spreader (IHS) is
attached to the package substrate and core and serves as the mating surface for
processor component thermal solutions, such as a heatsink. Figure 3-1 shows a sketch
of the processor package components and how they are assembled together. Refer to
the Processors and Socket in the Intel® Xeon® Processor 5500/5600 Series
Thermal/Mechanical Design Guide for complete details on the LGA1366 socket.
The package components shown in Figure 3-1 include the following:
1. Integrated Heat Spreader (IHS)
2. Thermal Interface Material (TIM)
3. Processor core (die)
4. Package substrate
5. Capacitors

3.1.2
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 3-2 and Figure 3-3 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.
3.1.3
Package Loading Specifications
Table 3-1 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.

Notes:
1.
These specifications apply to uniform compressive loading in a direction normal to the processor IHS.
2.
This is the maximum static force that can be applied by the heatsink and Independent Loading Mechanism
(ILM).
3.
These specifications are based on limited testing for design characterization. Loading limits are for the
package constrained by the limits of the processor socket.
4.
Dynamic loading is defined as an 11 ms duration average load superimposed on the static load
requirement.
5.
See Intel® Xeon® Processor 5500/5600 Series Thermal/Mechanical Design Guide for minimum socket load
to engage processor within socket.

Description
PSI#
O
Processor Power Status Indicator signal. This signal is asserted when maximum
possible processor core current consumption is less than 20A, Assertion of this
signal is an indication that the VR controller does not currently need to be able to
provide ICC above 20A, and the VR controller can use this information to move to
more efficient operation point. This signal will de-assert at least 3.3 µs before the
current consumption will exceed 20A. The minimum PSI# assertion time is 1 BCLK.
The minimum PSI# de-assertion time is 3.3 us.
This pin does not require a pull-down. For platforms which could experience false
PSI# assertions during power-up if this pin is left floating, a pull-up may be used
(1K-5K). Otherwise, it can be left floating. For boards currently pulling this signal to
Vss, this is not a critical change to make immediately, but it is recommended for
production builds.
RESET#
I
Asserting the RESET# 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
VCCPWRGOOD forces them to a known state. For a power-on Reset, RESET# must
stay active for at least one millisecond after VCC and BCLK have reached their
proper specifications. RESET# must not be kept asserted for more than 10 ms
while VCCPWRGOOD is asserted. RESET# must be held deasserted for at least one
millisecond before it is asserted again. RESET# must be held asserted before
VCCPWRGOOD is asserted. This signal does not have on-die termination and must
be terminated on the system board. RESET# is a common clock signal.
SKTOCC#
O
Socket occupied, platform must sense a VSS at this pin to enable POWER_ON.
TCK
I
TCK (Test Clock) provides the clock input for the processor Test Bus (also known as
the Test Access Port).
TDI
I
TDI (Test Data In) transfers serial test data into the processor. TDI provides the
serial input needed for JTAG specification support.
TDO
O
TDO (Test Data Out) transfers serial test data out of the processor. TDO provides
the serial output needed for JTAG specification support.
THERMTRIP#
O
Assertion of THERMTRIP# (Thermal Trip) indicates the processor junction
temperature has reached a level beyond which permanent silicon damage may
occur. Measurement of the temperature is accomplished through an internal
thermal sensor. Once activated, the processor will stop all execution and shut down
all PLLs. To further protect the processor, its core voltage (VCC), VTTA VTTD and VDDQ
must be removed following the assertion of THERMTRIP#. Once activated,
THERMTRIP# remains latched until RESET# is asserted. While the assertion of the
RESET# signal may de-assert THERMTRIP#, if the processor's junction temperature
remains at or above the trip level, THERMTRIP# will again be asserted after
RESET# is de-asserted.
TMS
I
TMS (Test Mode Select) is a JTAG specification support signal used by debug tools.
TRST#
I
TRST# (Test Reset) resets the Test Access Port (TAP) logic. TRST# must be driven
low during power on Reset.
VCC_SENSE

O
O
VCC_SENSE and VSS_SENSE provide an isolated, low impedance connection to the
processor core voltage and ground. They can used to sense or measure power near
the silicon with little noise.
VCC
I
Power for processor core.
VCCPWRGOOD
I
VCCPWRGOOD (Power Good) is a processor input. The processor requires this
signal to be a clean indication that BCLK, VCC, VCCPLL, VTTA and VTTD 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. VCCPWRGOOD can be driven inactive at
any time, but BCLK and power must again be stable before a subsequent rising
edge of VCCPWRGOOD. In addition at the time VCCPWRGOOD is asserted RESET#
must be active. The PWRGOOD 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.
VCCPLL
I
Analog Power for Clocks.
VDDQ
I

Thermal Specifications
6.1
Package Thermal Specifications
The Intel® Xeon® processor 5500 series 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. 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 5500/5600 Series Thermal/Mechanical Design Guide.
Note:
The boxed processor will ship with a component thermal solution. Refer to Section 8 for
details on the boxed processor.
6.1.1
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. See Table 6-2 and
Figure 6-1 for Intel® Xeon® Processor W5580 (130W TDP); Table 6-4 and Table 6-5,
and Figure 6-2 for Intel Xeon processor 5500 series Advanced SKU (95W TDP);
Table 6-7 and Figure 6-3 for Intel Xeon processor 5500 series Standard/Basic SKUs
(80W TDP); Table 6-9 and Figure 6-4 for Intel Xeon processor 5500 series Low Power
SKU (60W TDP); Table 6-11 and Figure 6-5 for Intel® Xeon® Processor L5518 (60W
TDP) supporting NEBS thermals; Table 6-13 and Figure 6-6 for Intel® Xeon® Processor
L5508 (38W TDP) supporting NEBS thermals. Thermal solutions not designed to
provide this level of thermal capability may affect the long-term reliability of the
processor and system. For more details on thermal solution design, please refer to this
processor’s TMDG.
The Intel Xeon processor 5500 series 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 6.3. If PECI is less than
TCONTROL, then the case temperature is permitted to exceed the Thermal Profile, but
PECI must remain at or below TCONTROL. If PECI >= TCONTROL, then the case
temperature must meet the Thermal Profile. 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# (see Section 6.2, Processor
Thermal Features). Systems that implement fan speed control must be designed to use
this data. Systems that do not alter the fan speed only need to guarantee the case
temperature meets the thermal profile specifications.
Intel® Xeon® Processor 5500 Series Datasheet, Volume 1
89
Thermal Specifications
The Intel Xeon Processor W5580 (see Figure 6-1; Table 6-2) supports a single Thermal
Profile. For this processor, it is expected that the Thermal Control Circuit (TCC) would
only be activated for very brief periods of time when running the most power-intensive
applications. Refer to the Intel® Xeon® Processor 5500/5600 Series Thermal /
Mechanical Design Guide for details on system thermal solution design, thermal profiles
and environmental considerations.
The Intel Xeon processor 5500 series Advanced SKU supports two thermal profiles,
either of which can be implemented. Both ensure adherence to Intel reliability
requirements. Thermal Profile A (see Figure 6-2; Table 6-4) is representative of a
volumetrically unconstrained thermal solution (that is, industry enabled 2U heatsink).
In this scenario, it is expected that the Thermal Control Circuit (TCC) would only be
activated for very brief periods of time when running the most power intensive
applications. Thermal Profile B (see Figure 6-2; Table 6-5) 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 B will violate the thermal specifications and may result in
permanent damage to the processor. Refer to this processor’s TMDG 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 the
Intel Xeon processor 5500 series Advanced SKU Thermal Profile B (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 (see
Figure 6-2 for Intel Xeon processor 5500 series Advanced SKU).
The Intel Xeon processor 5500 series Standard/Basic SKUs (see Figure 6-3; Table 6-7)
support a single Thermal Profile. For this processor, it is expected that the Thermal
Control Circuit (TCC) would only be activated for very brief periods of time when
running the most power-intensive applications. Refer to this processor’s TMDG for
details on system thermal solution design, thermal profiles and environmental
considerations.
The Intel Xeon processor 5500 series Low Power SKU (see Figure 6-4; Table 6-9)
supports a single Thermal Profile. For this processor, it is expected that the Thermal
Control Circuit (TCC) would only be activated for very brief periods of time when
running the most power-intensive applications. Refer to this processor’s TMDG for
details on system thermal solution design, thermal profiles and environmental
considerations.
The Intel Xeon Processor L5518 and Intel Xeon Processor L5508 both support Thermal
Profiles with nominal and short-term conditions designed to meet NEBS level 3
compliance (see Figure 6-5 and Figure 6-6 respectively). For these SKU’s operation at
either the nominal or short-term thermal profiles should result in virtually no TCC
activation.
Analysis indicates that real applications are unlikely to cause the processor to consume
maximum power dissipation for sustained time periods. Intel recommends that
complete thermal solution designs target the Thermal Design Power (TDP), instead of
the maximum processor power consumption. 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. For more details on this feature, refer to
Section 6.2. 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

Processor Thermal Features
6.2.1
Processor Temperature
A new feature in the Intel Xeon processor 5500 series is a software readable field in the
IA32_TEMPERATURE_TARGET register that contains the minimum temperature at
which the TCC will be activated and PROCHOT# 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.
Note:
There is no specified correlation between DTS temperatures and processor case
temperatures; therefore it is not possible to use this feature to ensure the processor
case temperature meets the Thermal Profile specifications.
6.2.2
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/VID control) involves the processor adjusting its operating frequency (via
the core ratio multiplier) and input voltage (via the VID signals). This combination of
reduced frequency and VID 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 (as with previous-generation processors supporting TM1 or
TM2).
The Adaptive Thermal Monitor feature must be enabled for the processor to be
operating within specifications. The temperature at which Adaptive Thermal
Monitor activates the Thermal Control Circuit is not user configurable and is not
software visible. 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 only 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
under-designed 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 appropriate
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.
The following sections provide more details on the different TCC mechanisms used by
Intel Xeon processor 5500 series.
Intel® Xeon® Processor 5500 Series Datasheet, Volume 1
103
Thermal Specifications
6.2.2.1
Frequency/VID Control
The processor uses Frequency/VID control whereby TCC activation causes the
processor to adjust its operating frequency (via the core ratio multiplier) and input
voltage (via the VID signals). This combination of reduced frequency and VID 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 operating frequency. This transition occurs very rapidly (on the
order of 2 µs).
Once the new operating frequency is engaged, the processor will transition to the new
core operating voltage by issuing a new VID code to the voltage regulator. The voltage
regulator must support dynamic VID steps to support this method. During the voltage
change, it will be necessary to transition through multiple VID codes to reach the target
operating voltage. Each step will be one VID table entry (see Table 2-2). 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
VID/frequency points. Transition of the VID code will occur first, to insure proper
operation once the processor reaches its normal operating frequency. Refer to
Figure 6-8 for an illustration of this ordering.

6.2.2.2
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). 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/VID targets
are at their minimum settings. It may also be initiated by software at a configurable
duty cycle.
6.2.3
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
utilizing the Intel Xeon processor 5500 series 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 On-Demand mode, the duty
cycle of the clock modulation is programmable via bits 3:1 of the same
IA32_CLOCK_MODULATION MSR. In On-Demand mode, the duty cycle can be
programmed from 12.5% on/ 87.5% off to 87.5% on/12.5% off in 12.5% 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.
6.2.4
PROCHOT# Signal
An external signal, PROCHOT# (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# is asserted. The processor can
be configured to generate an interrupt upon the assertion or de-assertion of
PROCHOT#.
The PROCHOT# 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# can
provide a means for thermal protection of system components.
As an output, PROCHOT# 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# by the system will activate
the TCC, if enabled, for all cores. TCC activation due to PROCHOT# assertion by the
system will result in the processor immediately transitioning to the minimum frequency
and corresponding voltage (using Freq/VID control). Clock modulation is not activated
in this case. The TCC will remain active until the system de-asserts PROCHOT#.
Intel® Xeon® Processor 5500 Series Datasheet, Volume 1
105
Thermal Specifications
PROCHOT# can allow 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# only 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# will only 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# 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# feature.
6.2.5
THERMTRIP# 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# definition in
Table 5-1). THERMTRIP# activation is independent of processor activity and does not
generate any Intel® QuickPath Interconnect transactions. The temperature at which
THERMTRIP# asserts is not user configurable and is not software visible.
6.3
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 that the PECI commands described in this document apply to the Intel
Xeon processor 5500 series only. Refer to Table 6-14 for the list of PECI
commands supported by the Intel Xeon processor 5500 series PECI client.

6.3.1.1
Thermal Management
Processor fan speed control is managed by comparing PECI thermal readings against
the processor-specific fan speed control reference point, or TCONTROL. Both TCONTROL
and PECI 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. Algorithms for fan speed management
using PECI thermal readings and the TCONTROL reference are documented in
Section 6.3.2.6.
PECI-based access to DRAM thermal readings and throttling control coefficients provide
a means for Board Management Controllers (BMCs) or other platform management
devices to feed hints into on-die memory controller throttling algorithms. These control
coefficients are accessible using PCI configuration space writes via PECI. The PECIbased configuration write functionality is defined in Section 6.3.2.5, and the DRAM
throttling coefficient control functions are documented in the Intel® Xeon® Processor
5500 Series Datasheet, Volume 2.
6.3.1.2
Platform Manageability
PECI allows full read access to error and status monitoring registers within the
processor’s PCI configuration space. It also provides insight into thermal monitoring
functions such as TCC activation timers and thermal error logs.
The exact list of RAS-related registers in the PCI configuration space can be found in
the Intel® Xeon® Processor 5500 Series Datasheet, Volume 2.

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()

Therefore, the Number of Domains reported is defined as the number of domains in
addition to Domain 0. For example, if the number 0b1 is returned, that would indicate
that the PECI client supports two domains.

GetTemp()
The GetTemp() command is used to retrieve the 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 Thermal Control Circuit
Activation temperature of the PECI device. Note that a value of zero represents the
temperature at which the 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 the Thermal Control Circuit Activation temperature. TCONTROL
may be extracted from the processor by issuing a PECI Mailbox MbxGet() (see
Section 6.3.2.8), or using a RDMSR instruction.
Please refer to Section 6.3.6 for details regarding temperature data formatting.

PCIConfigRd()
The PCIConfigRd() command gives sideband read access to the entire PCI configuration
space maintained in the processor. This capability does not include support for routethrough to downstream devices or sibling processors. The exact listing of supported
devices, functions, and registers can be found in the Intel® Xeon® Processor 5500
Series Datasheet, Volume 2. PECI originators may conduct a device/function/register
enumeration sweep of this space by issuing reads in the same manner that BIOS
would. A response of all 1’s indicates that the device/function/register is
unimplemented.
PCI configuration addresses are constructed as shown in the following diagram. Under
normal in-band procedures, the Bus number (including any reserved bits) would be
used to direct a read or write to the proper device. Since there is a one-to-one mapping
between any given client address and the bus number, any request made with a bad
Bus number is ignored and the client will respond with a ‘pass’ completion code but all
0’s in the data. The only legal bus number is 0x00. The client will return all 1’s in the
data response and ‘pass’ for the completion code for all of the following conditions:
• Unimplemented Device
• Unimplemented Function
• Unimplemented Register

Thermal Status Read / Clear

• Critical Temperature
Intel® Xeon® Processor 5500 Series Datasheet, Volume 1

Thermal Specifications
These status bits are a subset of the bits defined in the IA32_THERM_STATUS MSR on
the processor, and more details on the meaning of these bits may be found in the
Intel 64 and IA-32 Architectures Software Developer’s Manual, Vol. 3B.
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 log bits that it is
interested in tracking.
A bit set to 0b0 in the log bit clear mask will result in clearing the associated log bit. If
a mask bit is set to 0b0 and that bit is not a legal mask, a failing completion code will
be returned. A bit set to 0b1 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.

The counters may be simultaneously snapshot, simultaneously cleared, or
independently read. The simultaneous snapshot capability is provided in order to
guarantee concurrent reads even with significant read latency over the PECI bus. Each

Thermal Data Config Read / Write
The Thermal Data Configuration register allows the PECI host to control the window
over which thermal data is filtered. The default window is 256 ms. The host may
configure this window by writing a Thermal Filtering Constant as a power of two. For
example, sending a value of 9 results in a filtering window of 29 or 512 ms.

T-state Throttling Control Read / Write
PECI offers the ability to enable and configure ACPI T-state (core clock modulation)
throttling. ACPI T-state throttling forces all CPU cores into duty cycle clock modulation
where the core toggles between C0 (clocks on) and C1 (clocks off) states at the
specified duty cycle. This throttling reduces CPU performance to the duty cycle
specified and, more importantly, results in processor power reduction.
The Intel Xeon processor 5500 series software initiated T-state throttling and automatic
T-state throttling as part of the internal Thermal Monitor response mechanism (upon
TCC activation). The PECI T-state throttling control register read/write capability is
118
Intel® Xeon® Processor 5500 Series Datasheet, Volume 1
Thermal Specifications
managed only in the PECI domain. In-band software may not manipulate or read the
PECI T-state control setting. In the event that multiple agents are requesting T-state
throttling simultaneously, the CPU always gives priority to the lowest power setting, or
the numerically lowest duty cycle.
On Intel Xeon processor 5500 series, the only supported duty cycle is 12.5% (12.5%
clocks on, 87.5% clocks off). It is expected that T-state throttling will be engaged only
under emergency thermal or power conditions. Future products may support more duty
cycles, as defined in the following table:

MbxSend()
The MbxSend() command is utilized for sending requests to the generic Mailbox
interface. Those requests are in turn serviced by the processor with some nominal
latency and the result is deposited in the mailbox for reading. MbxGet() is used to
retrieve the response and details are documented in Section 6.3.2.8.
The details of processor mailbox capabilities are described in Section 6.3.2.6.1, and
many of the fundamental concepts of Mailbox ownership, release, and management are
discussed in Section 6.3.2.9.

Regardless of the function of the mailbox command, a request type modifier and 4-byte

If the MbxSend() response returns a bad Read FCS, the completion code can't be
trusted and the semaphore may or may not be taken. In order to clean out the
interface, an MbxGet() must be issued and the response data should be discarded.
6.3.2.8
MbxGet()
The MbxGet() command is utilized for retrieving response data from the generic
Mailbox interface as well as for unlocking the acquired mailbox. Please refer to
Section 6.3.2.7 for details regarding the MbxSend() command. Many of the
fundamental concepts of Mailbox ownership, release, and management are discussed
in Section 6.3.2.9.
6.3.2.8.1
Write Data
The MbxGet() command is designed to retrieve response data from a previously
deposited request. In order to guarantee alignment between the temporally separated
request (MbxSend) and response (MbxGet) commands, the originally granted
Transaction ID (sent as part of the passing MbxSend() completion code) must be issued
as part of the MbxGet() request.
Any mailbox request made with an illegal or unlocked Transaction ID will get a failed
completion code response. If the Transaction ID matches an outstanding transaction ID
associated with a locked mailbox, the command will complete successfully and the
response data will be returned to the originator.
Unlike MbxSend(), no Assured Write protocol is necessary for this command because
this is a read-only function.

Mailbox Usage Definition
6.3.2.9.1
Acquiring the Mailbox
The MbxSend() command is used to acquire control of the PECI mailbox and issue
information regarding the specific request. The completion code response indicates
whether or not the originator has acquired a lock on the mailbox, and that completion
code always specifies the Transaction ID associated with that lock (see
Section 6.3.2.9.2).
Once a mailbox has been acquired by an originating agent, future requests to acquire
that mailbox will be denied with an ‘interface busy’ completion code response.
The lock on a mailbox is not achieved until the last bit of the MbxSend() Read FCS is
transferred (in other words, it is not committed until the command completes). If the
host aborts the command at any time prior to that bit transmission, the mailbox lock
will be lost and it will remain available for any other agent to take control.
122
Intel® Xeon® Processor 5500 Series Datasheet, Volume 1
Thermal Specifications
6.3.2.9.2
Transaction ID
For all MbxSend() commands that complete successfully, the passing completion code
(0x4X) includes a 4-bit Transaction ID (‘X’). That ID is the key to the mailbox and must
be sent when retrieving response data and releasing the lock by using the MbxGet()
command.
The Transaction ID is generated internally by the processor and has no relationship to
the originator of the request. On Intel Xeon processor 5500 series, only a single
outstanding Transaction ID is supported. Therefore, it is recommended that all devices
requesting actions or data from the Mailbox complete their requests and release their
semaphore in a timely manner.
In order to accommodate future designs, software or hardware utilizing the PECI
mailbox must be capable of supporting Transaction IDs between 0 and 15.
6.3.2.9.3
Releasing the Mailbox
The mailbox associated with a particular Transaction ID is only unlocked / released
upon successful transmission of the last bit of the Read FCS. If the originator aborts the
transaction prior to transmission of this bit (presumably due to an FCS failure), the
semaphore is maintained and the MbxGet() command may be retried.
6.3.2.9.4
Mailbox Timeouts
The mailbox is a shared resource that can result in artificial bandwidth conflicts among
multiple querying processes that are sharing the same originator interface. The
interface response time is quick, and with rare exception, back to back MbxSend() and
MbxGet() commands should result in successful execution of the request and release of
the mailbox. In order to guarantee timely retrieval of response data and mailbox
release, the mailbox semaphore has a timeout policy. If the PECI bus has a cumulative
‘0 time of 1ms since the semaphore was acquired, the semaphore is automatically
cleared. In the event that this timeout occurs, the originating agent will receive a failed
completion code upon issuing a MbxGet() command, or even worse, it may receive
corrupt data if this MbxGet() command so happens to be interleaved with an
MbxSend() from another process. Please refer to Table 6-24 for more information
regarding failed completion codes from MbxGet() commands.
Timeouts are undesirable, and the best way to avoid them and guarantee valid data is
for the originating agent to always issue MbxGet() commands immediately following
MbxSend() commands.
Alternately, mailbox timeout can be disabled. BIOS may write MSR
MISC_POWER_MGMT (0x1AA), bit 11 to 0b1 in order to force a disable of this
automatic timeout.
6.3.2.9.5
Response Latency
The PECI mailbox interface is designed to have response data available within plenty of
margin to allow for back-to-back MbxSend() and MbxGet() requests. However, under
rare circumstances that are out of the scope of this specification, it is possible that the
response data is not available when the MbxGet() command is issued. Under these
circumstances, the MbxGet() command will respond with an Abort FCS and the
originator should re-issue the MbxGet() request.

Client Responses
6.3.4.1
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).
• Data is not ready.
• Assured Write FCS (AW FCS) failure. Note that 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.
6.3.4.2
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 also provide more detailed
information regarding the class of pass or fail. For all commands listed in Section 6.3.2
that support completion codes, each command’s completion codes is listed in its
respective section. What follows are some generalizations regarding completion codes.
An originator that is decoding these commands can apply a simple mask to determine
pass or fail. Bit 7 is always set on a failed command, and is cleared on a passing
command.

Note:
The codes explicitly defined in this table may be useful in PECI originator response
algorithms. All reserved or undefined codes may 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 6-27 applies to all codes and general response policies may be based
on that limited information.
6.3.5
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.
Please refer to the definition of each command in Section 6.3.2 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 IA32_THERM_STATUS MSR (0x19C) where it
is architecturally defined. 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 reference TCC activation temperature. As an
example, assume that the TCC activation temperature reference is 100°C. A PECI
thermal reading of -10 indicates that the processor is running approximately 10°C
below the TCC activation temperature, or 90°C. PECI temperature readings are not
reliable at temperatures above TCC activation (since the processor is operating out of
specification at this temperature). Therefore, the readings are never positive.
6.3.6.3
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 4 Hz, it is necessary for the thermal readings to reflect thermal
trends and not instantaneous readings. Therefore, PECI supports a configurable lowpass temperature filtering function. By default, this filter results in a thermal reading
that is a moving average of 256 samples taken at approximately 1msec intervals. This
filter’s depth, or smoothing factor, may be configured to between 1 sample and 1024
samples, in powers of 2. See the equation below for reference where the configurable
variable is ‘X’.
TN = TN-1 + 1/2X * (TSAMPLE - TN-1)

Client Management
6.3.7.1
Power-up Sequencing
The PECI client is fully reset during processor RESET# assertion. This means that any
transactions on the bus will be completely ignored, and the host will read the response
from the client as all zeroes. After processor RESET# deassertion, the Intel Xeon
processor 5500 series PECI client is operational enough to participate in timing
negotiations and respond with reasonable data. However, the client data is not
guaranteed to be fully populated until approximately 500 µS after processor RESET# is
deasserted. Until that time, data may not be ready for all commands. The client
responses to each command are as follows:

Device Discovery
The PECI client is available on all processors, and positive identification of the PECI
revision number can be achieved by issuing the GetDIB() command. Please refer to
Section 6.3.2.2 for details on GetDIB response formatting.
6.3.7.3
Client Addressing
The PECI client assumes a default address of 0x30. If nothing special is done to the
processor, all PECI clients will boot with this address. For DP enabled parts, a special
PECI_ID# pin is available to strap each PECI socket to a different node ID. The package
pin strap is evaluated at the assertion of VCCPWRGOOD (as depicted in Figure 6-27).
Since PECI_ID# is active low, tying the pin to ground results in a client address of
0x31, and tying it to VTT results in a client address of 0x30.
The client address may not be changed after VCCPWRGOOD assertion, until the next
power cycle on the processor. Removal of a processor from its socket or tri-stating a
processor in a DP configuration will have no impact to the remaining non-tri-stated
PECI client address.
6.3.7.4
C-States
The Intel Xeon processor 5500 series PECI client is fully functional under all core and
package C-states. Support for package C-states is a function of processor SKU and
platform capabilities. All package C-states (C1/C1E, C3, and C6) are annotated here for
completeness, but actual processor support for these C-states may vary.
Because the Intel Xeon processor 5500 series takes aggressive power savings actions
under the deepest C-states (C1/C1E, C3, and C6), PECI requests may have an impact
to platform power. The impact is documented below:
• Ping(), GetDIB(), GetTemp() and MbxGet() have no measurable impact on
processor power under C-states.
128
Intel® Xeon® Processor 5500 Series Datasheet, Volume 1
Thermal Specifications
• MbxSend(), PCIConfigRd() and PCIConfigWr() usage under package C-states may
result in increased power consumption because the processor must temporarily
return to a C0 state in order to execute the request. The exact power impact of a
pop-up to C0 varies by product SKU, the C-state from which the pop-up is initiated,
and the negotiated TBIT.

• The PECI client assumes a bus Idle state.
• The Thermal Filtering Constant is retained.
• PECI Node 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.

7.2
Clock Control and Low Power States
The processor supports low power states at the individual thread, core, and package
level for optimal power management. The processor implements software interfaces for
requesting low power states: MWAIT instruction extensions with sub-state hints, the
HLT instruction (for C1 and C1E) and P_LVLx reads to the ACPI P_BLK register block
mapped in the processor’s I/O address space. The P_LVLx I/O reads are converted to
equivalent MWAIT C-state requests inside the processor and do not directly result in
I/O reads to the system. The P_LVLx I/O Monitor address does not need to be set up
before using the P_LVLx I/O read interface.
Note:
Software may make C-state requests by using a legacy method involving I/O reads
from the ACPI-defined processor clock control registers, referred to as P_LVLx. This
feature is designed to provide legacy support for operating systems that initiate C-state
transitions via access to pre-defined ICH registers. The base P_LVLx register is P_LVL2,
corresponding to a C3 request. P_LVL3 is C6, and all P_LVL4+ are demoted to a C6.
P_LVLx is limited to a subset of C-states supported on the processor (for example,
P_LVL8 is not supported and will not cause an I/O redirection to a C8 request. Instead,
it will fall through like a normal I/O instruction). The range of I/O addresses that may
be converted into C-state requests is also defined in the PMG_IO_CAPTURE MSR, in the
132
Intel® Xeon® Processor 5500 Series Datasheet, Volume 1
Features
‘C-state Range’ field. This field maybe written by BIOS to restrict the range of I/O
addresses that are trapped and redirected to MWAIT instructions. Note that when I/O
instructions are used, no MWAIT substates can be defined, as therefore the request
defaults to have a sub-state or zero, but always assumes the ‘break on EFLAGS.IF==0’
control that can be selected using ECX with an MWAIT instruction.

C1/C1E State
C1/C1E is a low power state entered when all threads within a core execute a HLT or
MWAIT(C1E) instruction. The processor thread will transition to the C0 state upon
occurrence of an interrupt or an access to the monitored address if the state was
entered via the MWAIT instruction. RESET# will cause the processor to initialize itself
and return to C0.
A System Management Interrupt (SMI) handler will return execution to either Normal
state or the C1/C1E state. See the Intel® 64 and IA-32 Architectures Software
Developer's Manual, Volume III: System Programmer's Guide for more information.
While in C1/C1E state, the processor will process bus snoops and snoops from the
other threads.
To operate within specification, BIOS must enable the C1E feature for all installed
processors.
7.2.1.3
C3 State
Individual threads of the processor can enter the C3 state by initiating a P_LVL2 I/O
read to the P_BLK or an MWAIT(C3) instruction. Before entering core C3, the core
flushes the contents of its caches. Except for the caches, the processor core maintains
all its architectural state while in the C3 state. All of the clocks in the processor core are
stopped in the C3 state.
Because the core’s caches are flushed, the processor keeps the core in the C3 state
when the processor detects a snoop on the Intel QuickPath Interconnect Link or when
another logical processor in the same package accesses cacheable memory. The
processor core will transition to the C0 state upon occurrence of an interrupt. RESET#
will cause the processor core to initialize itself.
7.2.1.4
C6 State
Individual threads of the processor can enter the C6 state by initiating a P_LVL3 read to
the P_BLK or an MWAIT(C6) instruction. Before entering core C6, the processor saves it
state. The processor achieves additional power savings in the core C6 state.
7.2.2
Package Power State Descriptions
The package supports C0, C1/C1E, C3, and C6 power states. The package power state
is automatically resolved by the processor depending on the core power states and
permission from the rest of the system as described below.
7.2.2.1
Package C0 State
This is 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 another
component in the system has not granted permission to the processor to go into a low
power state. Individual components of the processor may be in low power states while
the package in C0.
7.2.2.2
Package C1/C1E State
The package will enter the C1/C1E low power state when at least one core is in the
C1/C1E state and the rest of the cores are in the C1/C1E or lower power state. The
processor will also enter the C1/C1E state when all cores are in a power state lower
134
Intel® Xeon® Processor 5500 Series Datasheet, Volume 1
Features
than C1/C1E but the package low power state is limited to C1/C1E via the
PMG_CST_CONFIG_CONTROL MSR. In the C1E state, the processor will automatically
transition to the lowest power operating point (lowest supported voltage and associated
frequency). When entering the C1E state, the processor will first switch to the lowest
bus ratio and then transition to the lower VID. No notification to the system occurs
upon entry to C1/C1E.
To operate within specification, BIOS must enable the C1E feature for all installed
processors.
7.2.2.3
Package C3 State
The package will enter the C3 low power state when all cores are in the C3 or lower
power state and the processor has been granted permission by the other component(s)
in the system to enter the C3 state. The package will also enter the C3 state when all
cores are in an idle state lower than C3 but other component(s) in the system have
only granted permission to enter C3.
If Intel QuickPath Interconnect L1 has been granted, the processor will disable some
clocks and PLLs and for processors with an Integrated Memory Controller, the DRAM
will be put into self-refresh.
7.2.2.4
Package C6 State
The package will enter the C6 low power state when all cores are in the C6 or lower
power state and the processor has been granted permission by the other component(s)
in the system to enter the C6 state. The package will also enter the C6 state when all
cores are in an idle state lower than C6 but the other component(s) have only granted
permission to enter C6.
If Intel QuickPath Interconnect L1 has been granted, the processor will disable some
clocks and PLLs and the shared cache will enter a deep sleep state. Additionally, for
processors with an Integrated Memory Controller, the DRAM will be put into selfrefresh.

Sleep States
The processor supports the ACPI sleep states S0, S1, S3, and S4/S5 as shown in. For
information on ACPI S-states and related terminology, refer to ACPI Specification. The
S-state transitions are coordinated by the processor in response PM Request (PMReq)
messages from the chipset. The processor itself will never request a particular S-state.

Power Reduction
If the chipset requests an S-state transition which is not allowed, a machine check error
will be generated by the processor.
Intel® Turbo Boost Technology
The processor supports ACPI Performance States (P-States). The P-state referred to as
P0 will be a request for Intel® Turbo Boost Technology (Intel® TBT). Intel TBT
opportunistically, and automatically, allows the processor to run faster than the marked
frequency if the part is operating below power, temperature and current limits. Max
Turbo Boost frequency is dependent on the number of active cores and varies by
processor line item configuration. Intel TBT doesn’t need special hardware support, and
can be enabled or disabled by BIOS.
7.5
Enhanced Intel SpeedStep® Technology
The processor features Enhanced Intel SpeedStep® Technology. Following are the key
features of Enhanced Intel SpeedStep Technology:
• Multiple voltage and frequency operating points provide optimal performance at the
lowest power.
• Voltage and frequency selection is software controlled by writing to processor
MSRs:
— If the target frequency is higher than the current frequency, VCC is ramped up
in steps by placing new values on the VID pins and the PLL then locks to the
new frequency.
— If the target frequency is lower than the current frequency, the PLL locks to the
new frequency and the VCC is changed through the VID pin mechanism.
— Software transitions are accepted at any time. If a previous transition is in
progress, the new transition is deferred until the previous transition completes.
• The processor controls voltage ramp rates internally to ensure smooth transitions.
• Low transition latency and large number of transitions possible per second:
— Processor core (including shared cache) is unavailable for less than 2µs during
the frequency transition.

Boxed Processor Specifications
8.1
Introduction
Intel boxed processors are intended for system integrators who build systems from
components available through distribution channels. The Intel Xeon processor 5500
series will be offered as an Intel boxed processor, however the thermal solution will be
sold separately.
Unlike previous-generation boxed processors, Intel Xeon processor 5500 series boxed
processors will not include thermal solution in the box. Intel will offer boxed thermal
solutions separately through the same distribution channels. Please reference
Section 8.1.1 - Section 8.1.4 for more details on Boxed Processor Thermal Solutions.
8.1.1
Available Boxed Thermal Solution Configurations
Intel will offer three different Boxed Heat Sink solutions to support the boxed
Processors.
• Boxed Intel “Combo” Thermal Solution. The Passive / Active Combination Heat Sink
Solution is intended for processors with a TDP up to 130W in a pedestal or 2U+
chassis with appropriate ducting)
• Boxed Intel “Active” Thermal Solution. The Active Heat Sink Solution is intended for
processors with a TDP of 80W or lower in pedestal chassis
• Boxed Intel “Passive” Thermal Solution. The 25.5 mm tall Passive Heat Sink
Solution is intended for processors with a TDP of 95W or lower in Blades, 1U, or 2U
chassis with appropriate ducting.
8.1.2
An Intel “Combo” Boxed Passive / Active Combination
Heat Sink Solution
The Passive / Active combination solution, based on a 2U passive heat sink with a
removable fan, is intended for use with processors with TDP’s up to 130 W. 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 8-2 and Figure 8-3
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 Passive / Active combination solution in the active fan configuration is primarily
designed to be used in a pedestal chassis where sufficient air inlet space is present. The
Passive / Active combination solution 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 Unified Retention System (URS).

Boxed Processor Specifications
8.1.3
Intel Boxed “Active” Heat Sink Solution
The Boxed Active solution will be available for purchase for processors with TDP’s of
80W and lower and will be an aluminum extrusion. This heat sink solution is intended
to be used as an active heat sink only for pedestal chassis. Figure 8-1 is a
representation of the heat sink solution.
Both active solutions will utilize 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 8.3 for more details on fan speed
control, also see Section 6.3 for more on the PWM and PECI interface along with Digital
Thermal Sensors (DTS).

8.1.4
Intel Boxed 25.5mm Tall Passive Heat Sink Solution
The boxed 25.5 mm Tall heatsink solution will be available for use with boxed
processors that have TDP’s of 95 W and lower. The 25.5 mm Tall passive solution is
designed to be used in 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 a more optimized heatsink design. Figure 8-4 is a representation of the heat
sink solution. The retention solution used for these products is called Unified Retention
System (URS).

Mechanical Specifications
This section documents the mechanical specifications of the boxed processor solution.
8.2.1
Boxed Processor Heat Sink Dimensions and Baseboard
Keepout Zones
The boxed processor and boxed thermal solution will be sold separately. Clearance is
required around the thermal solution to ensure unimpeded airflow for proper cooling.
Baseboard keepout zones are shown in Figure 8-5 through Figure 8-8. Physical space
requirements and dimensions for the boxed processor and assembled heat sink are
shown in Figure 8-9. Mechanical drawings for the 4-pin fan header and 4-pin connector
used for the active fan heat sink solution are represented in Figure 8-11 and
Figure 8-12.
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 3 for details on the processor mass.

Boxed Processor Retention Mechanism and Heat Sink
Support (URS)
Baseboards designed for use by a system integrator should include holes that are in
proper alignment with each other to support the boxed processor. Refer to Figure 8-5
for mounting hole dimensions.
Figure 8-13 illustrates the Unified Retention System (URS) and the Unified Backplate
Assembly. The URS is designed to extend air-cooling capability through the use of
larger heat sinks with minimal airflow blockage and bypass. URS retention transfers
load to the baseboard via the Unified Backplate Assembly. The URS spring, captive in
the heatsink, provides the necessary compressive load for the thermal interface
material. For specific design details on the URS and the Unified Backplate please refer
to the Intel® Xeon® Processor 5500 Series Thermal / Mechanical Design Guide.
All components of the URS heat sink solution will be captive to the heat sink and will
only require a Phillips screwdriver to attach to the Unified Backplate Assembly. When
installing the URS 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.

Fan Power Supply (“Combo” and “Active”
Solution)
The 4-pin PWM controlled thermal solution is being offered to help provide better
control over pedestal chassis acoustics. This is achieved though 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
Table 8-1 through Table 8-3 for details on the 4-pin active heat sink solution
connectors.

Boxed Processor Specifications
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.

Boxed Processor Cooling Requirements
As previously stated the boxed processor will have three cooling 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 6 of this document.

Boxed Processor Specifications
8.3.1.1
2U Passive / Active Combination Heat Sink Solution
Active Configuration:
The active configuration of the combination solution is designed to help pedestal
chassis users to meet the thermal processor requirements without the use of chassis
ducting. It may be still be necessary to implement some form of chassis air guide or air
duct to meet the TLA temperature of 40°C depending on the pedestal chassis layout.
Use of the active configuration in a 2U rackmount chassis is not recommended.
It is recommended that the ambient air temperature outside of the chassis be kept at
or below 35°C. The air passing directly over the processor thermal solution should not
be preheated by other system components. Meeting the processor’s temperature
specification is the responsibility of the system integrator.
This thermal solution is for use with 95 W and 130 W TDP processor SKUs.
Passive Configuration:
In the passive configuration it is assumed that a chassis duct will be implemented.
Processors with a TDP of 130 W or 95 W must provide a minimum airflow of 30 CFM at
0.205 in. H2O (51 m3/hr at 51.1 Pa) of flow impedance. For processors with a TDP of
130 W it is assumed that a 40°C TLA is met. This requires a superior chassis design to
limit the TRISE at or below 5°C with an external ambient temperature of 35°C. For
processors with a TDP of 95W it is assumed that a 55°C TLA is met.
8.3.1.2
Active Heat Sink Solution (Pedestal only)
This active solution is designed to help pedestal chassis users to meet the thermal
processor requirements without the use of chassis ducting. It may be still be necessary
to implement some form of chassis air guide or air duct to meet the TLA temperature of
49°C depending on the pedestal chassis layout. Use of this active solution in a 2U
rackmount chassis has not been validated.
It is recommended that the ambient air temperature outside of the chassis be kept at
or below 35°C. The air passing directly over the processor thermal solution should not
be preheated by other system components. 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 80W.
8.3.1.3
25.5 mm Tall Passive Heat Sink Solution (Blade + 1U + 2U Rack)
Note:
95 W SKU’s using the 25.5 mm Tall passive HS are only intended for use in 1U rack
configurations (Thermal Profile B). For use in 2U configurations see Section 8.3.1.2 for
details.
In the Blade, 1U and 2U configurations it is assumed that a chassis duct will be
implemented. Due to the complexity of the number of chassis and baseboard
configurations, several airflow and flow impedance values exist. Please refer to the
Intel® Xeon® Processor 5500/5600 Series Thermal / Mechanical Design Guide for
detailed mechanical drawings and specific airflow and impedance values applicable to
your use conditions. It is recommended that the ambient air temperature outside of the
chassis be kept at or below 35°C.
