Storage Options eSATA Port (some models)
Allows you to set a SATA port as an eSATA port for use with an external drive. Default is enabled.
This setting affects only the port with the black connector, labeled as eSATA on the system board.
This port should have the eSATA back panel connector attached to use eSATA drives. For more information, see the eSATA white paper at www.hp.com
.
NOTE: eSATA is not available on USDT systems.
SATA Emulation
Allows you to choose how the SATA controller and devices are accessed by the operating system. There are three supported options: IDE, RAID, and AHCI (default).
IDE - This is the most backwards-compatible setting of the three options. Operating systems usually do not require additional driver support in IDE mode.
RAID - Allows DOS and boot access to RAID volumes. Use this mode with the RAID device driver loaded in the operating system to take advantage of RAID features.
AHCI (default option) - Allows operating systems with AHCI device drivers loaded to take advantage of more advanced features of the SATA controller.
NOTE: The RAID/AHCI device driver must be installed prior to attempting to boot from a RAID/
AHCI volume. If you attempt to boot from a RAID/AHCI volume without the required device driver installed, the system will crash (blue screen). RAID volumes may become corrupted if they are booted to after disabling RAID.
NOTE: RAID is not available on USDT systems.
Removable Media Boot
Enables/disables ability to boot the system from removable media. Default is enabled.
Max eSATA Speed (some models)
Allows you to choose 1.5 Gbps or 3.0 Gpbs as the maximum eSATA speed. By default, the speed is limited to 1.5 Gbps for maximum reliability.

Heading
Allows you to set:
● POST mode (QuickBoot, Clear Memory, FullBoot, or FullBoot Every x Days).
◦ QuickBoot (default) = Do not clear memory or perform a memory test.
◦
◦ FullBoot = Memory test (count) on cold boot. Clears memory on all boots.
Clear Memory = No memory count on cold boot. Clears memory on all boots.
◦ FullBoot Every x Days = Memory count on 1st cold boot on or after the xth day. No more memory counts until 1st cold boot on or after x days. Clears memory on all boots.
● POST messages (enable/disable). Default is disabled.
● Press the ESC key for Startup Menu (Enable/Disable). Default is enabled.
● Option ROM Prompt (enable/disable). Enabling this feature will cause the system to display a message before loading option ROMs. Default is enabled.
● After Power Loss (off/on/previous state). Default is Power off. Setting this option to:
◦ Off—causes the computer to remain powered off when power is restored.
◦
◦ On—causes the computer to power on automatically as soon as power is restored.
Previous state—causes the computer to power on automatically as soon as power is restored, if it was on when power was lost.
NOTE: If you turn off power to the computer using the switch on a power strip, you will not be able to use the suspend/sleep feature or the Remote Management features.
● POST Delay (in seconds). Enabling this feature will add a user-specified delay to the POST process. This delay is sometimes needed for hard disks on some PCI cards that spin up very slowly, so slowly that they are not ready to boot by the time POST is finished. The POST delay also gives you more time to select F10 to enter Computer (F10) Setup. Default is
None.
● Remote Wakeup Boot Source (remote server/local hard drive). Default is Local hard drive.
● Factory Recovery Boot Support (Enable/Disable). Provides the ability for the BIOS to redirect the boot to the recovery partition on the user hard drive, if present. Some versions of the recovery software honor the F11 key press even when this feature is disabled by the BIOS.
Default is disabled.
● Bypass F1 Prompt on Configuration Changes (Enable/Disable). Allows you to set the computer not to confirm when changes were made. Default is disabled.
Allows you to set the computer to turn on automatically at a time you specify.
Allows you to set resources for or disable Legacy devices.
Select the Legacy device's IRQ, DMA, and I/O Range. The settings may not take effect for all operating systems. To hide a device from the operating system, see Security > Device Security.

Bus Options
Device Options
On some models, allows you to enable or disable:
● PCI SERR# Generation. Default is enabled.
● PCI VGA Palette Snooping, which sets the VGA palette snooping bit in PCI configuration space; only needed when more than one graphics controller is installed. Default is disabled.
Allows you to set:
● Monitor Tracking (enable/disable). Allows ROM to save monitor asset information. Default is disabled.
● Printer mode (Bi-Directional, EPP + ECP, Output Only). Default is EPP+ECP.
● Num Lock State at Power-On (off/on). Default is off.
● Integrated Video (enable/disable). Use this option to disable the integrated video controller when another video controller is present in the system. Default is enabled.
● Internal Speaker (some models) (does not affect external speakers). Default is enabled.
● NIC Option ROM Download (PXE, iSCSI, disabled). The BIOS contains an embedded NIC option ROM to allow the unit to boot through the network to a PXE server. This is typically used to download a corporate image to a hard drive. The NIC option ROM takes up memory space below 1MB commonly referred to as DOS Compatibility Hole (DCH) space. This space is limited. This F10 option will allow users to disable the downloading of this embedded NIC option ROM thus giving more DCH space for additional PCI cards which may need option ROM space. The default will be to have the NIC option-ROM-enabled. Default is
PXE.
● SATA RAID Option ROM Download (enable/disable). The BIOS contains an embedded
SATA RAID option ROM for RAID support. This can be temporarily disabled to save DCH space. Note that with the option ROM disabled, users will be unable to boot to hard drives in the system while running in RAID mode. Default is disabled.
● Multi-Processor (enable/disable). Use this option to disable multi-processor support under the OS. Default is enabled.
● Hyper threading (enable/disable) (some models). Use this option to disable processor hyperthreading.
● Turbo Mode (enable/disable). Allows you to enable and disable the Intel Turbo Mode feature, which allows one core of the system to run at a higher than standard frequency and power if other cores are idle. Default is enabled.

VGA Configuration
AMT Configuration
Displayed only if there is an add-in video card in the system. Allows you to specify which VGA controller will be the “boot” or primary VGA controller.
Allows you to set:
● AMT (enable/disable). Allows you to enable or disable functions of the embedded
Management Engine (ME) such as Active Management Technology (AMT). If set to disable, the Management Engine is set to a temporarily disabled state and will not provide functions beyond necessary system configuration. Default is enabled.
● Unconfigure AMT/ME (enable/disable). Allows you to unconfigure any provisioned management settings for AMT. The AMT settings are restored to factory defaults. This feature should be used with caution as AMT will not be able to provide any set AMT management functions once unconfigured. Default is disabled.
● Hide Unconfigure ME Confirmation Prompt (enable/disable). Allows you to set the system to not display the confirmation to unconfigure ME.
● Watchdog Timer (enable/disable). Allows you to set amount of time for a operating system and BIOS watchdog alert to be sent if the timers are not deactivated. BIOS watchdog is deactivated by BIOS and would indicate that a halt occurred during execution if the alert is sent to the management console. An operating system alert is deactivated by the operating system image and would indicate that a hang occurred during its initialization. Default is enabled.
Recovering the Configuration Settings
This method of recovery requires that you first perform the Save to Removable Media command with the Computer Setup (F10) Utility before Restore is needed. (See
Save to Removable Media on page 12
in the Computer Setup—File table.)
NOTE: It is recommended that you save any modified computer configuration settings to a USB flash media device and save the device for possible future use.
To restore the configuration, insert the USB flash media device with the saved configuration and perform the Restore from Removable Media command with the Computer Setup (F10) Utility. (See
Restore from Removable Media on page 12
in the Computer Setup—File table.)

5 Routine Care, SATA Drive Guidelines, and Disassembly Preparation
This chapter provides general service information for the computer. Adherence to the procedures and precautions described in this chapter is essential for proper service.
CAUTION: When the computer is plugged into an AC power source, voltage is always applied to the system board. You must disconnect the power cord from the power source before opening the computer to prevent system board or component damage.
Electrostatic Discharge Information
A sudden discharge of static electricity from your finger or other conductor can destroy static-sensitive devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An electronic device exposed to electrostatic discharge (ESD) may not appear to be affected at all and can work perfectly throughout a normal cycle. The device may function normally for a while, but it has been degraded in the internal layers, reducing its life expectancy.
Networks built into many integrated circuits provide some protection, but in many cases, the discharge contains enough power to alter device parameters or melt silicon junctions.
Generating Static
The following table shows that:
● Different activities generate different amounts of static electricity.
● Static electricity increases as humidity decreases.

Preventing Electrostatic Damage to Equipment
Many electronic components are sensitive to ESD. Circuitry design and structure determine the degree of sensitivity. The following packaging and grounding precautions are necessary to prevent damage to electric components and accessories.
● To avoid hand contact, transport products in static-safe containers such as tubes, bags, or boxes.
● Protect all electrostatic parts and assemblies with conductive or approved containers or packaging.
● Keep electrostatic sensitive parts in their containers until they arrive at static-free stations.
● Place items on a grounded surface before removing them from their container.
● Always be properly grounded when touching a sensitive component or assembly.
● Avoid contact with pins, leads, or circuitry.
● Place reusable electrostatic-sensitive parts from assemblies in protective packaging or conductive foam.
Personal Grounding Methods and Equipment
Use the following equipment to prevent static electricity damage to equipment:
● Wrist straps are flexible straps with a maximum of one-megohm ± 10% resistance in the ground cords. To provide proper ground, a strap must be worn snug against bare skin. The ground cord must be connected and fit snugly into the banana plug connector on the grounding mat or workstation.
● Heel straps/Toe straps/Boot straps can be used at standing workstations and are compatible with most types of shoes or boots. On conductive floors or dissipative floor mats, use them on both feet with a maximum of one-megohm ± 10% resistance between the operator and ground.

Grounding the Work Area
To prevent static damage at the work area, use the following precautions:
● Cover the work surface with approved static-dissipative material. Provide a wrist strap connected to the work surface and properly grounded tools and equipment.
● Use static-dissipative mats, foot straps, or air ionizers to give added protection.
● Handle electrostatic sensitive components, parts, and assemblies by the case or PCB laminate.
Handle them only at static-free work areas.
● Turn off power and input signals before inserting and removing connectors or test equipment.
● Use fixtures made of static-safe materials when fixtures must directly contact dissipative surfaces.
● Keep work area free of nonconductive materials such as ordinary plastic assembly aids and
Styrofoam.
● Use field service tools, such as cutters, screwdrivers, and vacuums, that are conductive.

Operating Guidelines
To prevent overheating and to help prolong the life of the computer:
● Keep the computer away from excessive moisture, direct sunlight, and extremes of heat and cold.
● Operate the computer on a sturdy, level surface. Leave a 10.2-cm (4-inch) clearance on all vented sides of the computer and above the monitor to permit the required airflow.
● Never restrict the airflow into the computer by blocking any vents or air intakes. Do not place the keyboard, with the keyboard feet down, directly against the front of the desktop unit as this also restricts airflow.
● Occasionally clean the air vents on all vented sides of the computer. Lint, dust, and other foreign matter can block the vents and limit the airflow. Be sure to unplug the computer before cleaning the air vents.
● Never operate the computer with the cover or side panel removed.
● Do not stack computers on top of each other or place computers so near each other that they are subject to each other’s re-circulated or preheated air.
● If the computer is to be operated within a separate enclosure, intake and exhaust ventilation must be provided on the enclosure, and the same operating guidelines listed above will still apply.
● Keep liquids away from the computer and keyboard.
● Never cover the ventilation slots on the monitor with any type of material.
● Install or enable power management functions of the operating system or other software, including sleep states.
Routine Care
General Cleaning Safety Precautions
1.
Never use solvents or flammable solutions to clean the computer.
2.
Never immerse any parts in water or cleaning solutions; apply any liquids to a clean cloth and then use the cloth on the component.
3.
Always unplug the computer when cleaning with liquids or damp cloths.
4.
Always unplug the computer before cleaning the keyboard, mouse, or air vents.
5.
Disconnect the keyboard before cleaning it.
6.

Cleaning the Computer Case
Follow all safety precautions in
General Cleaning Safety Precautions on page 45
before cleaning the computer.
Operating Guidelines 45
To clean the computer case, follow the procedures described below:
● To remove light stains or dirt, use plain water with a clean, lint-free cloth or swab.
● For stronger stains, use a mild dishwashing liquid diluted with water. Rinse well by wiping it with a cloth or swab dampened with clear water.
● For stubborn stains, use isopropyl (rubbing) alcohol. No rinsing is needed as the alcohol will evaporate quickly and not leave a residue.
● After cleaning, always wipe the unit with a clean, lint-free cloth.
● Occasionally clean the air vents on the computer. Lint and other foreign matter can block the vents and limit the airflow.
Cleaning the Keyboard
Follow all safety precautions in
General Cleaning Safety Precautions on page 45 before cleaning the
keyboard.
To clean the tops of the keys or the keyboard body, follow the procedures described in
CAUTION: Use safety glasses equipped with side shields before attempting to clean debris from under the keys.
● Visible debris underneath or between the keys may be removed by vacuuming or shaking.
● Canned, pressurized air may be used to clean debris from under the keys. Caution should be used as too much air pressure can dislodge lubricants applied under the wide keys.
● If you remove a key, use a specially designed key puller to prevent damage to the keys. This tool is available through many electronic supply outlets.
CAUTION: Never remove a wide leveled key (like the space bar) from the keyboard. If these keys are improperly removed or installed, the keyboard may not function properly.
● Cleaning under a key may be done with a swab moistened with isopropyl alcohol and squeezed out. Be careful not to wipe away lubricants necessary for proper key functions. Use tweezers to remove any fibers or dirt in confined areas. Allow the parts to air dry before reassembly.
Cleaning the Monitor
● Wipe the monitor screen with a clean cloth moistened with water or with a towelette designed for cleaning monitors. Do not use sprays or aerosols directly on the screen; the liquid may seep into the housing and damage a component. Never use solvents or flammable liquids on the monitor.
● To clean the monitor body follow the procedures in
Cleaning the Computer Case on page 45 .
46 Chapter 5 Routine Care, SATA Drive Guidelines, and Disassembly Preparation
Cleaning the Mouse
Before cleaning the mouse, ensure that the power to the computer is turned off.
● Clean the mouse ball by first removing the retaining plate and the ball from the housing. Pull out any debris from the ball socket and wipe the ball with a clean, dry cloth before reassembly.
●
To clean the mouse body, follow the procedures in Cleaning the Computer Case on page 45
.
Service Considerations
Listed below are some of the considerations that you should keep in mind during the disassembly and assembly of the computer.
Power Supply Fan
The power supply fan is a variable-speed fan based on the temperature in the power supply.
CAUTION: The cooling fan is always on when the computer is in the “On” mode. The cooling fan is off when the computer is in “Standby,” “Suspend,” or “Off” modes.
You must disconnect the power cord from the power source before opening the computer to prevent system board or component damage.
Tools and Software Requirements
To service the computer, you need the following:
● Torx T-15 screwdriver (HP screwdriver with bits, PN 161946-001)
● Torx T-15 screwdriver with small diameter shank (for certain front bezel removal)
● Flat-bladed screwdriver (may sometimes be used in place of the Torx screwdriver)
● Phillips #2 screwdriver
● Diagnostics software
● HP tamper-resistant T-15 wrench (Smart Cover FailSafe Key, PN 166527-001) or HP tamperresistant bits (Smart Cover FailSafe Key, PN 166527-002)
Screws
The screws used in the computer are not interchangeable. They may have standard or metric threads and may be of different lengths. If an incorrect screw is used during the reassembly process, it can damage the unit. HP strongly recommends that all screws removed during disassembly be kept with the part that was removed, then returned to their proper locations.
CAUTION: Metric screws have a black finish. U.S. screws have a silver finish and are used on hard drives only.
CAUTION: As each subassembly is removed from the computer, it should be placed away from the work area to prevent damage.
Service Considerations 47
Cables and Connectors
Most cables used throughout the unit are flat, flexible cables. These cables must be handled with care to avoid damage. Apply only the tension required to seat or unseat the cables during insertion or removal from the connector. Handle cables by the connector whenever possible. In all cases, avoid bending or twisting the cables, and ensure that the cables are routed in such a way that they cannot be caught or snagged by parts being removed or replaced.
CAUTION: When servicing this computer, ensure that cables are placed in their proper location during the reassembly process. Improper cable placement can damage the computer.
Hard Drives
Handle hard drives as delicate, precision components, avoiding all physical shock and vibration. This applies to failed drives as well as replacement spares.
● If a drive must be mailed, place the drive in a bubble-pack mailer or other suitable protective packaging and label the package “Fragile: Handle With Care.”
● Do not remove hard drives from the shipping package for storage. Keep hard drives in their protective packaging until they are actually mounted in the CPU.
● Avoid dropping drives from any height onto any surface.
● If you are inserting or removing a hard drive, turn off the computer. Do not remove a hard drive while the computer is on or in standby mode.
● Before handling a drive, ensure that you are discharged of static electricity. While handling a drive, avoid touching the connector. For more information about preventing electrostatic damage, refer to
Electrostatic Discharge Information on page 42
● Do not use excessive force when inserting a drive.
● Avoid exposing a hard drive to liquids, temperature extremes, or products that have magnetic fields such as monitors or speakers.
Lithium Coin Cell Battery
The battery that comes with the computer provides power to the real-time clock and has a minimum lifetime of about three years.
See the appropriate removal and replacement chapter for the chassis you are working on in this guide for instructions on the replacement procedures.
WARNING!
This computer contains a lithium battery. There is a risk of fire and chemical burn if the battery is handled improperly. Do not disassemble, crush, puncture, short external contacts, dispose in water or fire, or expose it to temperatures higher than 140ºF (60ºC). Do not attempt to recharge the battery.
NOTE: Batteries, battery packs, and accumulators should not be disposed of together with the general household waste. In order to forward them to recycling or proper disposal, please use the public collection system or return them to HP, their authorized partners, or their agents.

SATA Data Cable
Always use an HP approved SATA 3.0 Gb/s cable as it is fully backwards compatible with the SATA
1.5 Gb/s drives.
Current HP desktop products ship with SATA 3.0 Gb/s hard drives.
SATA data cables are susceptible to damage if overflexed. Never crease a SATA data cable and never bend it tighter than a 30 mm (1.18 in) radius.
The SATA data cable is a thin, 7-pin cable designed to transmit data for only a single drive.
SMART ATA Drives
The Self Monitoring Analysis and Recording Technology (SMART) ATA drives for the HP Personal
Computers have built-in drive failure prediction that warns the user or network administrator of an impending failure or crash of the hard drive. The SMART drive tracks fault prediction and failure indication parameters such as reallocated sector count, spin retry count, and calibration retry count. If the drive determines that a failure is imminent, it generates a fault alert.
Cable Management
Always follow good cable management practices when working inside the computer.
● Keep cables away from major heat sources like the heat sink.
● Do not jam cables on top of expansion cards or memory modules. Printed circuit cards like these are not designed to take excessive pressure on them.
● Keep cables clear of sliding or moveable parts to prevent them from being cut or crimped when the parts are moved.
● When folding a flat ribbon cable, never fold to a sharp crease. Sharp creases may damage the wires.
SATA Hard Drives 49
● Some flat ribbon cables come prefolded. Never change the folds on these cables.
● Do not bend any cable sharply. A sharp bend can break the internal wires.
● Never bend a SATA data cable tighter than a 30 mm (1.18 in) radius.
● Never crease a SATA data cable.
● Do not rely on components like the drive cage, power supply, or computer cover to push cables down into the chassis. Always position the cables to lay properly by themselves.
Hard Drive Capacities
The combination of the file system and the operating system used in the computer determines the maximum usable size of a drive partition. A drive partition is the largest segment of a drive that may be properly accessed by the operating system. A single hard drive may therefore be subdivided into a number of unique drive partitions in order to make use of all of its space.
Because of the differences in the way that drive sizes are calculated, the size reported by the operating system may differ from that marked on the hard drive or listed in the computer specification.
Drive size calculations by drive manufacturers are bytes to the base 10 while calculations by
Microsoft are bytes to the base 2.

The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3-
SDRAM) dual inline memory modules (DIMMs).
DIMMs
The memory sockets on the system board can be populated with up to four industry-standard DIMMs.
These memory sockets are populated with at least one preinstalled DIMM. To achieve the maximum memory support, you can populate the system board with up to 16-GB of memory configured in a high-performing dual channel mode.
DDR3-SDRAM DIMMs
CAUTION: This product DOES NOT support DDR3 Ultra Low Voltage (DDR3U) memory. The processor is not compatible with DDR3U memory and if you plug DDR3U memory into the system board, it can cause the physical damage to the DIMM or invoke system malfunction.
For proper system operation, the DDR3-SDRAM DIMMs must be:
● industry-standard 240-pin
● unbuffered non-ECC PC3-12800 DDR3-1600 MHz-compliant
● 1.5 volt DDR3-SDRAM DIMMs
The DDR3-SDRAM DIMMs must also:
● support CAS latency 11 DDR3 1600 MHz (11-11-11 timing)
● contain the mandatory JEDEC SPD information
In addition, the computer supports:
● 512-Mbit, 1-Gbit, and 2-Gbit non-ECC memory technologies
● single-sided and double-sided DIMMs
● DIMMs constructed with x8 and x16 DDR devices; DIMMs constructed with x4 SDRAM are not supported
NOTE: The system will not operate properly if you install unsupported DIMMs.
Populating DIMM Sockets
There are four DIMM sockets on the system board, with two sockets per channel. The sockets are labeled DIMM1, DIMM2, DIMM3, and DIMM4. Sockets DIMM1 and DIMM2 operate in memory channel B. Sockets DIMM3 and DIMM4 operate in memory channel A.
Memory 57
The system will automatically operate in single channel mode, dual channel mode, or flex mode, depending on how the DIMMs are installed.
● The system will operate in single channel mode if the DIMM sockets are populated in one channel only.
● The system will operate in a higher-performing dual channel mode if the total memory capacity of the DIMMs in Channel A is equal to the total memory capacity of the DIMMs in Channel B.
The technology and device width can vary between the channels. For example, if Channel A is populated with two 1-GB DIMMs and Channel B is populated with one 2-GB DIMM, the system will operate in dual channel mode.
● The system will operate in flex mode if the total memory capacity of the DIMMs in Channel A is not equal to the total memory capacity of the DIMMs in Channel B. In flex mode, the channel populated with the least amount of memory describes the total amount of memory assigned to dual channel and the remainder is assigned to single channel. For optimal speed, the channels should be balanced so that the largest amount of memory is spread between the two channels.
If one channel will have more memory than the other, the larger amount should be assigned to
Channel A. For example, if you are populating the sockets with one 2-GB DIMM, and three 1-GB
DIMMs, Channel A should be populated with the 2-GB DIMM and one 1-GB DIMM, and Channel
B should be populated with the other two 1-GB DIMMs. With this configuration, 4-GB will run as dual channel and 1-GB will run as single channel.
● In any mode, the maximum operational speed is determined by the slowest DIMM in the system.
Installing DIMMs
CAUTION: You must disconnect the power cord and wait approximately 30 seconds for the power to drain before adding or removing memory modules. Regardless of the power-on state, voltage is always supplied to the memory modules as long as the computer is plugged into an active AC outlet.
Adding or removing memory modules while voltage is present may cause irreparable damage to the memory modules or system board.
The memory module sockets have gold-plated metal contacts. When upgrading the memory, it is important to use memory modules with gold-plated metal contacts to prevent corrosion and/or oxidation resulting from having incompatible metals in contact with each other.
Static electricity can damage the electronic components of the computer or optional cards. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a
grounded metal object. For more information, refer to Electrostatic Discharge Information on page 42
.
When handling a memory module, be careful not to touch any of the contacts. Doing so may damage the module.

Figure 6-6 Installing a DIMM
NOTE: A memory module can be installed in only one way. Match the notch on the module with the tab on the memory socket.
Populate the black DIMM sockets before the white DIMM sockets.
For maximum performance, populate the sockets so that the memory capacity is spread as
equally as possible between Channel A and Channel B. Refer to Populating DIMM Sockets on page 57
for more information.

The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3-
SDRAM) dual inline memory modules (DIMMs).
DIMMs
The memory sockets on the system board can be populated with up to four industry-standard DIMMs.
These memory sockets are populated with at least one preinstalled DIMM. To achieve the maximum memory support, you can populate the system board with up to 16-GB of memory configured in a high-performing dual channel mode.
DDR3-SDRAM DIMMs
CAUTION: This product DOES NOT support DDR3 Ultra Low Voltage (DDR3U) memory. The processor is not compatible with DDR3U memory and if you plug DDR3U memory into the system board, it can cause the physical damage to the DIMM or invoke system malfunction.
For proper system operation, the DDR3-SDRAM DIMMs must be:
● industry-standard 240-pin
● unbuffered non-ECC PC3-12800 DDR3-1600 MHz-compliant
● 1.5 volt DDR3-SDRAM DIMMs
The DDR3-SDRAM DIMMs must also:
● support CAS latency 11 DDR3 1600 MHz (11-11-11 timing)
● contain the mandatory JEDEC SPD information
In addition, the computer supports:
● 512-Mbit, 1-Gbit, and 2-Gbit non-ECC memory technologies
● single-sided and double-sided DIMMs
● DIMMs constructed with x8 and x16 DDR devices; DIMMs constructed with x4 SDRAM are not supported
NOTE: The system will not operate properly if you install unsupported DIMMs.
Populating DIMM Sockets
There are four DIMM sockets on the system board, with two sockets per channel. The sockets are labeled DIMM1, DIMM2, DIMM3, and DIMM4. Sockets DIMM1 and DIMM2 operate in memory channel B. Sockets DIMM3 and DIMM4 operate in memory channel A.
Memory 97
The system will automatically operate in single channel mode, dual channel mode, or flex mode, depending on how the DIMMs are installed.
● The system will operate in single channel mode if the DIMM sockets are populated in one channel only.
● The system will operate in a higher-performing dual channel mode if the total memory capacity of the DIMMs in Channel A is equal to the total memory capacity of the DIMMs in Channel B.
The technology and device width can vary between the channels. For example, if Channel A is populated with two 1-GB DIMMs and Channel B is populated with one 2-GB DIMM, the system will operate in dual channel mode.
● The system will operate in flex mode if the total memory capacity of the DIMMs in Channel A is not equal to the total memory capacity of the DIMMs in Channel B. In flex mode, the channel populated with the least amount of memory describes the total amount of memory assigned to dual channel and the remainder is assigned to single channel. For optimal speed, the channels should be balanced so that the largest amount of memory is spread between the two channels.
If one channel will have more memory than the other, the larger amount should be assigned to
Channel A. For example, if you are populating the sockets with one 2-GB DIMM, and three 1-GB
DIMMs, Channel A should be populated with the 2-GB DIMM and one 1-GB DIMM, and Channel
B should be populated with the other two 1-GB DIMMs. With this configuration, 4-GB will run as dual channel and 1-GB will run as single channel.
● In any mode, the maximum operational speed is determined by the slowest DIMM in the system.
Installing DIMMs
CAUTION: You must disconnect the power cord and wait approximately 30 seconds for the power to drain before adding or removing memory modules. Regardless of the power-on state, voltage is always supplied to the memory modules as long as the computer is plugged into an active AC outlet.
Adding or removing memory modules while voltage is present may cause irreparable damage to the memory modules or system board.
The memory module sockets have gold-plated metal contacts. When upgrading the memory, it is important to use memory modules with gold-plated metal contacts to prevent corrosion and/or oxidation resulting from having incompatible metals in contact with each other.
Static electricity can damage the electronic components of the computer or optional cards. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a
grounded metal object. For more information, refer to Electrostatic Discharge Information on page 42
.
When handling a memory module, be careful not to touch any of the contacts. Doing so may damage the module.
1.
Prepare the computer for disassembly ( Preparation for Disassembly on page 91 ).
2.
Remove the access panel ( Access Panel on page 92 ).
3.
Rotate up the internal drive bay housing to access the memory module sockets on the system board.
98 Chapter 7 Removal and Replacement Procedures Small Form Factor (SFF) Chassis

Figure 7-6 Installing a DIMM
NOTE: A memory module can be installed in only one way. Match the notch on the module with the tab on the memory socket.
Populate the black DIMM sockets before the white DIMM sockets.
For maximum performance, populate the sockets so that the memory capacity is spread as
equally as possible between Channel A and Channel B. Refer to Populating DIMM Sockets on page 97
for more information.
5.
Push the module down into the socket, ensuring that the module is fully inserted and properly seated. Make sure the latches are in the closed position (3).
6.
Repeat steps 4 and 5 to install any additional modules.

Installing and Removing Drives
When installing drives, follow these guidelines:
● The primary Serial ATA (SATA) hard drive must be connected to the dark blue primary SATA connector on the system board labeled SATA0. If you are adding a second hard drive, connect it to the white connector on the system board labeled SATA1.
● Connect a SATA optical drive to the white SATA connector on the system board labeled SATA2.
● Connect an optional eSATA adapter cable to the black SATA connector on the system board labeled ESATA.
● Connect a media card reader USB cable to the USB connector on the system board labeled
MEDIA.
● The power cable for the SATA drives is a three-headed cable that is plugged into the system board with the first connector routed to the rear of the hard drive, the second connector routed to the rear of the 3.5” drive, and the third connector routed to the rear of the 5.25” optical drive.
● The system does not support Parallel ATA (PATA) optical drives or PATA hard drives.
● You must install guide screws to ensure the drive will line up correctly in the drive cage and lock in place. HP has provided extra guide screws for the drive bays (five 6-32 standard screws and four M3 metric screws), installed in the front of the chassis, under the front bezel. The 6-32 standard screws are required for a secondary hard drive. All other drives (except the primary hard drive) use M3 metric screws. The HP-supplied metric screws are black and the HPsupplied standard screws are silver. If you are replacing the primary hard drive, you must

9 POST Error Messages
This appendix lists the error codes, error messages, and the various indicator light and audible sequences that you may encounter during Power-On Self-Test (POST) or computer restart, the probable source of the problem, and steps you can take to resolve the error condition.
POST Message Disabled suppresses most system messages during POST, such as memory count and non-error text messages. If a POST error occurs, the screen will display the error message. To manually switch to the POST Messages Enabled mode during POST, press any key (except F10 ,
F11 , or F12 ). The default mode is POST Message Disabled.
The speed at which the computer loads the operating system and the extent to which it is tested are determined by the POST mode selection.
Quick Boot is a fast startup process that does not run all of the system level tests, such as the memory test. Full Boot runs all of the ROM-based system tests and takes longer to complete.
Full Boot may also be enabled to run every 1 to 30 days on a regularly scheduled basis. To establish the schedule, reconfigure the computer to the Full Boot Every x Days mode, using Computer Setup.
NOTE: For more information on Computer Setup, see
Computer Setup (F10) Utility on page 10

10 Password Security and Resetting
CMOS
This computer supports security password features, which can be established through the Computer
Setup Utilities menu.
This computer supports two security password features that are established through the Computer
Setup Utilities menu: setup password and power-on password. When you establish only a setup password, any user can access all the information on the computer except Computer Setup. When you establish only a power-on password, the power-on password is required to access Computer
Setup and any other information on the computer. When you establish both passwords, only the setup password will give you access to Computer Setup.
When both passwords are set, the setup password can also be used in place of the power-on password as an override to log in to the computer. This is a useful feature for a network administrator.
If you forget the password for the computer, you can clear that password so you can gain access to the information on the computer by resetting the password jumper.
CAUTION: Pushing the CMOS button will reset CMOS values to factory defaults. It is important to back up the computer CMOS settings before resetting them in case they are needed later. Back up is easily done through Computer Setup. See
Computer Setup (F10) Utility on page 10 for information on
backing up the CMOS settings.
