Installing Additional Memory

The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3­SDRAM) 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 high­performing dual channel mode.

DDR3-SDRAM DIMMs

For proper system operation, the DDR3-SDRAM DIMMs must be:

industry-standard 240-pin

●

unbuffered non-ECC PC3-8500 DDR3-1066 MHz-compliant or PC3-10600 DDR3-1333 MHz-

●

compliant

1.5 volt DDR3-SDRAM DIMMs

●

The DDR3-SDRAM DIMMs must also:

support CAS latency 7 DDR3 1066 MHz (7-7-7 timing) and CAS latency 9 DDR3 1333 MHz (9-9-9

●

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.

16 Chapter 2 Hardware Upgrades ENWW

Populating DIMM Sockets

There are four DIMM sockets on the system board, with two sockets per channel. The sockets are
labeled XMM1, XMM2, XMM3, and XMM4. Sockets XMM1 and XMM2 operate in memory channel A.
Sockets XMM3 and XMM4 operate in memory channel B.

Figure 2-7 DIMM Socket Locations

Table 2-1 DIMM Socket Locations

Item Description Socket Color

1 XMM1 socket, Channel A (populate first) Black

2 XMM2 socket, Channel A (populate third) White

3 XMM3 socket, Channel B (populate second) White

4 XMM4 socket, Channel B (populate fourth) White

NOTE: A DIMM must occupy the black XMM1 socket. Otherwise, the system will display

a POST error message indicating that a memory module must be installed in the wrong
socket.

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

ENWW Installing Additional Memory 17

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. If you see an LED light on the system board, voltage is still present.

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 Appendix D,

on page 54.

When handling a memory module, be careful not to touch any of the contacts. Doing so may damage
the module.

D Electrostatic Discharge

A discharge of static electricity from a finger or other conductor may damage system boards or other
static-sensitive devices. This type of damage may reduce the life expectancy of the device.

Preventing Electrostatic Damage

To prevent electrostatic damage, observe the following precautions:

Avoid hand contact by transporting and storing products in static-safe containers.

●

Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.

●

Place parts on a grounded surface before removing them from their containers.

●

Avoid touching pins, leads, or circuitry.

●

Always be properly grounded when touching a static-sensitive component or assembly.

●

Grounding Methods

There are several methods for grounding. Use one or more of the following methods when handling or
installing electrostatic-sensitive parts:

Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis. Wrist

●

straps are flexible straps with a minimum of 1 megohm +/- 10 percent resistance in the ground
cords. To provide proper ground, wear the strap snug against the skin.

Use heelstraps, toestraps, or bootstraps at standing workstations. Wear the straps on both feet

●

when standing on conductive floors or dissipating floor mats.

Use conductive field service tools.

●

Use a portable field service kit with a folding static-dissipating work mat.

●

If you do not have any of the suggested equipment for proper grounding, contact an HP authorized
dealer, reseller, or service provider.

NOTE: For more information on static electricity, contact an HP authorized dealer, reseller, or service

provider.

E Computer Operating Guidelines,

Routine Care and Shipping Preparation

Computer Operating Guidelines and Routine Care

Follow these guidelines to properly set up and care for the computer and monitor:

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.

Never operate the computer with the access panel or any of the expansion card slot covers

●

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.

Turn off the computer before you do either of the following:

●

Wipe the exterior of the computer with a soft, damp cloth as needed. Using cleaning products

◦

may discolor or damage the finish.

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.

ENWW Computer Operating Guidelines and Routine Care 55

Optical Drive Precautions

Be sure to observe the following guidelines while operating or cleaning the optical drive.

Operation

Do not move the drive during operation. This may cause it to malfunction during reading.

●

Avoid exposing the drive to sudden changes in temperature, as condensation may form inside the

●

unit. If the temperature suddenly changes while the drive is on, wait at least one hour before you
turn off the power. If you operate the unit immediately, it may malfunction while reading.

Avoid placing the drive in a location that is subject to high humidity, extreme temperatures,

●

mechanical vibration, or direct sunlight.

Cleaning

Clean the panel and controls with a soft, dry cloth or a soft cloth lightly moistened with a mild

●

detergent solution. Never spray cleaning fluids directly on the unit.

Avoid using any type of solvent, such as alcohol or benzene, which may damage the finish.

●

Safety

If any object or liquid falls into the drive, immediately unplug the computer and have it checked by an
authorized HP service provider.

Shipping Preparation

Follow these suggestions when preparing to ship the computer:

1. Back up the hard drive files on PD discs, tape cartridges, CDs, or USB flash drives. Be sure that

the backup media is not exposed to electrical or magnetic impulses while stored or in transit.

NOTE: The hard drive locks automatically when the system power is turned off.

2. Remove and store all removable media.

3. Turn off the computer and external devices.

4. Disconnect the power cord from the electrical outlet, then from the computer.

5. Disconnect the system components and external devices from their power sources, then from the

computer.

NOTE: Ensure that all boards are seated properly and secured in the board slots before shipping

the computer.

6. Pack the system components and external devices in their original packing boxes or similar

packaging with sufficient packing material to protect them.
