Before Working Inside Your Computer
Use the following safety guidelines to help protect your computer from potential damage and to
help ensure your own personal safety.
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions located
in the Product Information Guide.
CAUTION: Handle components and cards with care. Do not touch the components or contacts on a
card. Hold a card by its edges or by its metal mounting bracket. Hold a component such as a processor
by its edges, not by its pins.
NOTICE: Only a certified service technician should perform repairs on your computer. Damage due to
servicing that is not authorized by Dell is not covered by your warranty.
www.dell.com | support.dell.com
NOTICE: When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable
itself. Some cables have a connector with locking tabs; if you are disconnecting this type of cable, press
in on the locking tabs before you disconnect the cable. As you pull connectors apart, keep them evenly
aligned to avoid bending any connector pins. Also, before you connect a cable, ensure that both
connectors are correctly oriented and aligned.
NOTICE: To avoid damaging the computer, perform the following steps before you begin working inside
the computer.
1
Turn off your computer (see "Turning Off Your Computer" on page 69).
NOTICE: To disconnect a network cable, first unplug the cable from your computer and then unplug it
from the network port or device.
2
Disconnect any telephone or telecommunication lines from the computer.
3
Disconnect your computer and all attached devices from their electrical outlets, and then
press the power button to ground the system board.
CAUTION: To guard against electrical shock, always unplug your computer from the electrical outlet
before opening the cover.
4
Open the computer cover (see "Opening the Computer Cover" on page 76).
NOTICE: Before touching anything inside your computer, ground yourself by touching an unpainted
metal surface, such as the metal at the back of the computer. While you work, periodically touch an
unpainted metal surface to dissipate any static electricity that could harm internal components.

Memory
You can increase your computer memory by installing memory modules on the system board.
Your computer supports DDR2 memory. For additional information on the type of memory
supported by your computer, see "Memory" on page 127.
DDR2 Memory Overview
• DDR2 memory modules should be installed in
pairs of matched memory size and speed
. If the
DDR2 memory modules are not installed in matched pairs, the computer will continue to
operate, but with a slight reduction in performance. See the label on the upper-right or upper-
left corner of the module to determine the module’s capacity.
NOTE: Always install DDR2 memory modules in the order indicated on the system board.
The recommended memory configurations are:
– A pair of matched memory modules installed in DIMM connectors 1 and 2
or
– A pair of matched memory modules installed in DIMM connectors 1 and 2 and another
matched pair installed in DIMM connectors 3 and 4
NOTICE: Do not install ECC memory modules.
• If you install mixed pairs of PC2-4300 (DDR2 533-MHz) and PC2-5300 (DDR2 667-MHz)
memory, the modules function at the speed of the slowest module installed.
• Be sure to install a single memory module in DIMM connector 1, the connector closest to the
processor, before you install modules in the other connectors.

matched pair of memory modules in DIMM
connectors 3 and 4 (black securing clips)
matched pair of modules in DIMM
connectors 1 and 2 (white securing clips)
NOTICE: If you remove your original memory modules from the computer during a memory upgrade,
keep them separate from any new modules that you may have, even if you purchased the new modules
from Dell. If possible, do not pair an original memory module with a new memory module. Otherwise, your
computer may not start properly. You should install your original memory modules in pairs either in DIMM
connectors 1 and 2 or DIMM connectors 3 and 4.
NOTE: Memory purchased from Dell is covered under your computer warranty.
Addressing Memory Configurations
®
®
If you are using a 32-bit operating system such as Microsoft
Windows
XP, your computer will
support a maximum of 2 GB of memory. If you are using a 64-bit operating system, your
computer will support a maximum of 8 GB (2-GB DIMMs in each of the four slots) of memory.

General Installation Guidelines
Connect serial ATA hard drives to the SATA0 - SATA3 connectors on the system board. Connect
CD/DVD drives to the IDE connector.
When you connect two IDE devices to a single IDE interface cable and configure them for the
cable select setting, the device attached to the last connector on the interface cable is the
primary or the boot device (drive 0), and the device attached to the middle connector on the
interface cable is the secondary device (drive 1). See the drive documentation in your upgrade
kit for information on configuring devices for the cable select setting.
Removing and Installing Parts 95
Connecting Drive Cables
When you install a drive, you connect two cables—a DC power cable and a data cable—to the
back of the drive and to the system board. Some drives may also have an audio connector; one
end of the audio cable attaches to the drive connector and the other end attaches to the system
board.
Drive Interface Connectors
Most interface connectors are keyed for correct insertion; that is,
a notch or a missing pin on one connector matches a tab or a
