Installing Additional Memory
The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2-
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 8 GB of memory configured in a high-
performing dual channel mode.
DDR2-SDRAM DIMMs
For proper system operation, the DDR2-SDRAM DIMMs must be:
industry-standard 240-pin
●
●
unbuffered PC2-4300 533 MHz-compliant, PC2-5300 667 MHz-compliant, or PC2-6400 800 MHz-
compliant
1.8 volt DDR2-SDRAM DIMMs
●
The DDR2-SDRAM DIMMs must also:
support CAS latency 4 (DDR2/533 MHz and DDR2/667 MHz) and CAS latency 5 (DDR2/667 MHz
and DDR2/800 MHz)
●
contain the mandatory JEDEC SPD information
●
In addition, the computer supports:
256Mbit, 512Mbit, and 1Gbit 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 start 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 XMM1, XMM2, XMM3, and XMM4. Sockets XMM1 and XMM2 operate in memory channel A.
Sockets XMM3 and XMM4 operate in memory channel B.

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 256MB DIMMs and Channel B is populated with one 512MB 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. For example,
if you are populating the sockets with one 1GB DIMM, two 512MB DIMMs, and one 256MB DIMM,
one channel should be populated with the 1GB DIMM and one 256MB DIMM and the other channel
●

should be populated with the two 512MB DIMMs. With this configuration, 2 GB will run as dual
channel and 256 MB 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 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.
After removing the computer cover, look for the LED on the system board between the DIMM
sockets. If the LED is illuminated, the system still has power. Turn off the computer and remove
the power cord before proceeding.
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
When handling a memory module, be careful not to touch any of the contacts. Doing so may
damage the module.
1. Remove/disengage any security devices that prohibit opening the computer.
2. Remove all removable media, such as diskettes or compact discs, from the computer.
3. Turn off the computer properly through the operating system, then turn off any external devices.
4. Disconnect the power cord from the power outlet and disconnect any external devices.
CAUTION Regardless of the power-on state, voltage is always present on the system
board as long as the system is plugged into an active AC outlet. You must disconnect the
power cord to avoid damage to the internal components of the computer.
5. If the computer is on a stand, remove the computer from the stand.
6. Remove the computer cover.
CAUTION After removing the computer cover, look for the LED on the system board
between the DIMM sockets. If the LED is illuminated, the system still has power. Turn off

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

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 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.
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.
