Installing Additional Memory
The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2SDRAM) 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 4 GB of memory configured in a highperforming dual channel mode.
DDR2-SDRAM DIMMs
For proper system operation, the DDR2-SDRAM DIMMs must be:
●
industry-standard 240-pin
●
unbuffered PC2-5300 667 MHz-compliant
●
1.8 volt DDR2-SDRAM DIMMs
The DDR2-SDRAM DIMMs must also:
●
support CAS latency 4 and 5 for DDR2/667 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.
ENWW
Installing Additional Memory
15
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 XMM3 operate in memory channel A.
Sockets XMM2 and XMM4 operate in memory channel B.

The system will automatically operate in single channel mode or dual channel mode, depending on how
the DIMMs are installed.
16
●
The system will operate in a higher-performing dual channel mode if like-sized DIMMs of equal
capacity are populated in one or both pairs of sockets. For example, if the Channel A far socket
and Channel B far socket (the two black sockets) both have 1024MB DIMMs installed, the system
will operate in dual channel mode. If this system had two additional DIMMs added into the white
sockets, they could be a pair of 256MB, 512MB, or 1024MB DIMMs and the system would still
operate in dual channel mode. For purposes of “like sizes,” a single-sided 512MB DIMM and a
double-sided 512MB DIMM would not be the same size because they have different numbers of
memory chips on them.
●
The system will operate in single channel mode if the DIMMs are populated in any other supported
configuration. Supported configurations consist of any combination of one, two, three, or four
DIMMs as long as socket XMM3 is populated before socket XMM1 in Channel A, and socket XMM4
is populated before socket XMM2 in Channel B.
Chapter 2 Hardware Upgrades
ENWW
●
If a single DIMM is installed, it must be installed in the XMM3 socket.
●
In either 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, Electrostatic Discharge.
When handling a memory module, be careful not to touch any of the contacts. Doing so may
damage the module.
NOTE You must remove the optical drive to add or remove memory modules.
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 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 poweron 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

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.

Computer Operating Guidelines and Routine Care
Follow these guidelines to properly set up and care for the computer and monitor:
ENWW
●
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.
Computer Operating Guidelines and Routine Care
