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 4GB
of memory configured in a high-performing dual channel mode.
DDR2-SDRAM DIMMs
For proper system operation, if the computer supports
DDR2-SDRAM DIMMs, the DIMMs must be:
■ industry-standard 240-pin
■ unbuffered PC3200 400 MHz-compliant or PC4300
533 MHz-compliant
■ 1.8 volt DDR2-SDRAM DIMMs
The DDR2-SDRAM DIMMs must also:
■ support CAS latency 2.5 or 3 (CL = 2.5 or CL = 3)
■ 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
2–4 www.hp.com Hardware Reference Guide
Populating DIMM Sockets
The system will automatically operate in single channel mode, dual
channel Asymmetric mode, or a higher-performing dual channel
Interleaved 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 dual channel Asymmetric 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.
■ The system will operate in a higher-performing dual channel
Interleaved 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. However, 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 Interleaved mode.
■ In any mode, the maximum operational speed is determined by
the slowest DIMM in the system. For example, if the system is
populated with a DIMM that is 333 MHz and a second DIMM
that is 400 MHz, the system will run at the slower of the two
speeds.
Hardware Upgrades
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.

Installing DIMMs
CAUTION: The memory module sockets have gold metal contacts. When
Ä
upgrading the memory, it is important to use memory modules with gold
metal contacts to prevent corrosion and/or oxidation resulting from having
incompatible metals in contact with each other.
CAUTION: Static electricity can damage the electronic components of
Ä
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 informations, refer to Appendix D,
“Electrostatic Discharge.”
CAUTION: When handling a memory module, be careful not to touch
Ä
any of the contacts. Doing so may damage the module.

5. Open both latches of the memory module socket 1, and insert the
memory module into the socket 2.
Installing a DIMM
A memory module can be installed in only one way. Match the notch
✎
on the module with the tab on the memory socket.
For maximum performance, poplulate the sockets so that the memory
✎
capacity of Channel A is equal to the memory capacity of Channel B.
Fo example, if you have one preinstalled DIMM in socket XMM1 and
are adding a second DIMM, it is recommended that you install a
DIMM of equal memory capacity into the XMM3 or XMM4 socket.
6. 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.
7. Repeat steps 5 and 6 to install any additional modules.
8. Replace the access panel.
The computer should automatically recognize the additional memory
the next time you turn on the computer.

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.
D
■ 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.
Hardware Reference Guide www.hp.com D–1
Electrostatic Discharge
■ 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.
For more information on static electricity, contact an HP authorized
✎
dealer, reseller, or service provider.
