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.

www.dell.com | support.dell.com

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.

Installing Memory

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions

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

filled-in hole on the other connector.

www.dell.com | support.dell.com

When you connect an IDE cable, ensure that you align the
