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.

✎
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
