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 the technical specifications for memory.
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 in the upper-right corner of the module to determine the module's capacity.
NOTE: The module's capacity label can also be seen in the upper-left corner of the module.
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 PC2-4200 (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.
1
matched pair of memory modules in DIMM connectors 3 and 4 (black securing clips)
2
matched pair of modules in DIMM connectors 1 and 2 (white securing clips)
NOTE: Memory purchased from Dell is covered under your computer warranty.
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.
Addressing Memory Configurations
If 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 located in the Product Information Guide.
NOTICE: To prevent static damage to components inside your computer, discharge static electricity from your body before you touch any of your computer's electronic components. You can do so by touching an unpainted metal surface on the computer chassis.
Lay the computer on its side so that the system board is on the bottom of the inside of the
computer.

Connect your computer and devices to electrical outlets, and turn them on.
Right-click the My Computer icon and click Properties.
Click the General tab.
To verify that the memory is installed correctly, check the amount of memory (RAM) listed.
Removing Memory
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions located in the Product Information Guide.
NOTICE: To prevent static damage to components inside your computer, discharge static electricity from your body before you touch any of your computer's electronic components. You can do so by touching an unpainted metal surface on the computer chassis.
Press out the securing clip at each end of the memory module connector.
Grasp the module and pull up.
If the module is difficult to remove, gently ease the module back and forth to remove it from the connector.

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.
Connecting Drive Cables
When you install a drive, you connect two cablesa DC power cable and a data cableto 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.
When you connect an IDE cable, ensure that you align the colored stripe with the pin 1 connector. When you disconnect an IDE cable, grasp the colored pull tab and pull until the connector detaches.
When connecting and disconnecting a serial ATA cable, hold the cable by the connector at each end.
NOTE: The system board serial ATA connector may have an attached cover or shroud.

Replacing the Battery
A coin-cell battery maintains computer configuration, date, and time information. The battery can last several years. If you have to repeatedly reset time and date information after turning on the computer, replace the battery.
CAUTION: A new battery can explode if it is incorrectly installed. Replace the battery only with the same or equivalent type recommended by the manufacturer. Discard used batteries according to the manufacturer's instructions.
To replace the battery:
Record all the information on the screens in the system setup program so that you can restore
the correct settings in step 8.
NOTICE: If you pry the battery out of its socket with a blunt object, be careful not to touch the system board with the object. Ensure that the object is inserted between the battery and the socket before you attempt to pry out the battery. Otherwise, you may damage the system board by prying off the socket or by breaking circuit traces on the system board.
Remove the battery by prying it out of its socket with your fingers.
Insert the new battery (CR2032) into the socket with the side labeled "+" against the metal
