Hardware Upgrades
Serviceability Features
Your computer includes features that make it easier to upgrade and
service.
Installation Sequence
It is very important that you follow this sequence of steps to ensure
the proper installation of any optional equipment. For more
information about Computer Setup, refer to the Computer Setup
(F10) Utility Guide. If the computer is already on, turn it off and
disconnect the power cord from the wall outlet.
ÅWARNING: To reduce the risk of personal injury from electrical shock
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.
ÅWARNING: To reduce the risk of electrical shock, fire, or damage to the
equipment, do not plug telecommunications/telephone connectors into
the network interface controller (NIC) receptacles.
ÄCAUTION: 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 E in this guide for
additional information on preventing electrostatic discharge.

Hardware Upgrades
Installing Additional Memory
The computer comes with Double Data Rate-Synchronous dynamic
random access memory (DDR-SDRAM) dual inline memory
modules (DIMMs).
DIMMs
The memory sockets on the system board can be populated with
industry-standard DIMMs. These memory module slots are populated
with at least one preinstalled memory module. To achieve the
maximum memory support, you may be required to replace the
preinstalled DIMM with a higher capacity DIMM.
DDR-SDRAM DIMMs
For proper system operation, if your system supports DDR-SDRAM
DIMMs, the DIMMs must be industry-standard 184-pin, unbuffered
PC 2100 266 MHz-compliant, 2.5 volt DDR-SDRAM DIMMs. The
DDR-SDRAM DIMMs must support CAS Latency 2 or 2.5 (CL = 2
or CL = 2.5). They must also contain the mandatory Joint Electronic
Device Engineering Council (JEDEC) Serial Presence Detect (SPD)
information. DIMMs constructed with x4 SDRAM are not supported;
the system will not start using unsupported DIMMs.
✎The nVidia nForce chipset does not support ECC memory.

2–6 Hardware Reference Guide
Hardware Upgrades
Installing DDR-SDRAM DIMMs
ÄCAUTION: Your memory module sockets have gold metal contacts.
When upgrading your 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.
ÄCAUTION: 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.
ÄCAUTION: When handling a memory module, be careful not to touch
any of the contacts. Doing so may damage the module.
1. Shut down the operating system properly, then power off the
computer and any external devices, then disconnect the power
cord from the power outlet.
2. Remove the cover and locate the memory module sockets.
ÅWARNING: To reduce risk of personal injury from hot surfaces, allow
the internal system components to cool before touching.

3. Open both latches of the memory module socket 1, and insert the
memory module into the socket 2.
Installing a DIMM
✎Begin by installing a module into the socket nearest the preinstalled
module, and install the modules following the numerical order of the
sockets.
4. A memory module can be installed in only one way. Match the
notch on the module with the tab on the memory socket. Push
the module down into the socket, ensuring that the module is
properly seated and the latches on each end of the socket snap
into place 3.
5. Complete the procedure described in the “Reassembling the
Computer” section of this chapter.

Removing or Upgrading a Drive
The computer supports up to four drives which may be installed in
various configurations.
■CD-ROM or CD-R/RW drive
■DVD-ROM or DVD-R/RW drive
■Hard drive
■Diskette drive
This section describes the procedure for replacing or upgrading the
storage drives. A Torx or Flathead screwdriver is needed to replace a
drive.
ÄCAUTION: Make sure you back up your personal files on the hard drive
to an external storage device, such as a CD, before removing the hard
drive. Failure to do so will result in data loss. After replacing the hard
drive, you will need to run the Compaq Restore Plus! CD to load the
Compaq factory-installed files.
