If your computer only has one memory module installed on the system board, you can increase your computer memory by installing an additional memory module.
Your computer supports DDR2 memory. For additional information on the type of memory supported by your computer, see Specifications.
DDR2 Memory Overview
Your computer has a minimum memory configuration of one DDR2 memory module. This memory module must be installed in DIMM1. If two or more DDR2 memory modules are installed, they should be installed in pairs of matched memory size, speed, and technology. 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 module to determine the module's capacity.
NOTE: Always install DDR2 memory modules in the order indicated on the system board.
NOTICE: Do not install ECC or buffered memory modules. Only unbuffered, non-ECC memory is supported.
The recommended memory configurations are:
A memory module installed in connector DIMM1
A pair of matched memory modules installed in connectors DIMM1 and DIMM2
A pair of matched memory modules installed in connectors DIMM1 and DIMM2 and another matched pair installed in connectors DIMM3 and DIMM4
If you install mixed pairs of DDR2 533-MHz (PC2-4300) and DDR2 667-MHz (PC2-5400) memory, the modules function at the slower installed speed.
Be sure to populate the memory modules in order starting with DIMM1, the connector closest to the edge of the system board, before you install modules in the other connectors.

Channel B: matched pair of memory modules in connectors DIMM_3 and DIMM_4 (black 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.

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.
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 of the settings in system setup (see System Setup Options) so that you can restore the
correct settings in step 8.
Loosen the captive screw on each side of the heat sink assembly.
CAUTION: Despite having a plastic shield, the heat sink assembly may be very hot during normal operation. Be sure that it has had sufficient time to cool before you touch it.
NOTICE: To avoid damaging the processor or processor socket, slide the heat sink assembly forward and backwards to break the thermal grease seal between the processor and heat sink. If you do not break the seal first, the processor may stick to the heat sink assembly while rotating the assembly upward.
Rotate the heat sink assembly upward, and remove the assembly from the computer.
