Serviceability Features
This computer includes features that make it easy to upgrade and
service. No tools are needed for most of the installation procedures
described in this chapter.
Warnings and Cautions
Before performing upgrades be sure to carefully read all of the
applicable instructions, cautions, and warnings in this guide.
WARNING: To reduce the risk of personal injury from electrical shock
Å
and/or hot surfaces, be sure to disconnect the power cord from the wall
outlet, and allow the internal system components to cool before touching.

equipment, do not plug telecommunications/telephone connectors into the
network interface controller (NIC) receptacles.
CAUTION: Static electricity can damage the electronic components of
the computer or optional equipment. Before beginning these procedures,
ensure that you are discharged of static electricity by briefly touching a
grounded metal object. Refer to Appendix D, “Electrostatic Discharge” in
this guide for additional information on preventing electrostatic discharge.
CAUTION: Before removing the computer cover ensure that the computer
is turned off and that the power cord is disconnected from the electrical
outlet.

stand before removing the computer cover. To remove the computer
from the stand:
1. Turn off the computer properly through the operating system,
then turn off any external devices.
2. Disconnect the power cord from the power outlet and the
computer, and disconnect any external devices.
3. Lift the computer off the stand.

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:
Hardware Upgrades
■ 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
Hardware Reference Guide www.hp.com 2-5
Hardware Upgrades
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.
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.

CAUTION: The memory module sockets have gold metal contacts. When
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
the computer or optional cards. Before beginning these procedures,
ensure that you are discharged of static electricity by briefly touching a
grounded metal object. Refer to Appendix D, “Electrostatic Discharge” for
more information.
CAUTION: When handling a memory module, be careful not to touch
any of the contacts. Doing so may damage the module.
1. Turn off the computer properly through the operating system,
then turn off any external devices.
Å
2. Disconnect the power cord from the power outlet and disconnect
any external devices.
3. Remove the computer from the stand and lay the computer on its
side.
4. Remove the computer cover.
5. Locate the memory module sockets on the system board.
WARNING: To reduce risk of personal injury from hot surfaces, allow
the internal system components to cool before touching.

6. Open both latches of the memory module socket 1, then 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, populate the sockets so that the memory
capacity of Channel A is equal to the memory capacity of Channel B.
For 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.
7. 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.

8. Repeat steps 7 and 8 for any additional modules that you want to
install.
9. Replace the computer cover.
The computer automatically recognizes the additional memory the
next time you power on the computer.
