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.
WARNI NG: 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.
WARNI NG: To reduce the risk of electrical shock, fire, or damage to the
Å
equipment, do not plug telecommunications/telephone connectors into the
network interface controller (NIC) receptacles.

Hardware Upgrades
CAUTION: Static electricity can damage the electronic components of
Ä
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 E, “Electrostatic Discharge” in
this guide for additional information on preventing electrostatic discharge.
CAUTION: Before removing the computer cover ensure that the computer
Ä
is turned off and that the power cord is disconnected from the electrical
outlet.

Using the Small Form Factor Computer in a Minitower Configuration
The Small Form Factor computer can be used in either a minitower or
desktop configuration. To use it in the minitower configuration, stand
the computer up on its right side as shown in the illustration below.
Ensure at least 4 inches (10.2 cm) of space on all sides of the
✎
computer remains clear and free of obstructions.
Changing from Desktop to Minitower Configuration
To further stabilize the computer in a minitower configuration, you
✎
can purchase a tower stand from HP.

Removing the Computer Cover
To remove the computer cover:
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.
CAUTION: Before removing the computer cover, ensure that the
Ä
computer is turned off and that the power cord is disconnected from
the electrical outlet.
3. Press the buttons on the left and right sides of the computer 1
then slide the computer cover forward until it stops 2 and lift it
up and off the chassis.

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, the DDR2-SDRAM DIMMs must be:
■ industry-standard 240-pin
■ unbuffered PC3200 400 MHz-compliant or PC4300
533 MHz-compliant
Hardware Upgrades
■ 1.8 volt DDR2-SDRAM DIMMs
The DDR2-SDRAM DIMMs must also:
■ support CAS latency 3, 4, or 5 (CL = 3, CL = 4, or CL = 5) for
DDR2/400 MHz; supports CAS latency 4 or 5 (CL = 4 or CL = 5)
for DDR2/533 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
The system will not start if you install unsupported DIMMs.

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 400 MHz and a second DIMM
that is 533 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 E, “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.
2. Disconnect the power cord from the power outlet and disconnect
any external devices.
3. Remove the computer cover. Refer to “Removing the Computer
Cover.”
4. Locate the memory module sockets on the system board.
WARNI NG: To reduce risk of personal injury from hot surfaces, allow
Å
the internal system components to cool before touching.
