For information on the type of memory supported by your computer, look under "Memory" in the Technical Specifications section.
NOTICE: Before you install new memory modules, download the most recent BIOS for your computer
from the Dell Support website at support.dell.com.
DDR2 Memory Overview
For best performance, DDR2 memory modules 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.
The recommended memory configurations are:
A memory module installed in connector CHA_DIMM.
or
A pair of matched memory modules installed in connectors CHA_DIMM and CHB_DIMM.
NOTICE: Do not install ECC memory modules.
Be sure to install a single memory module in CHA_DIMM, the connector closest to the processor, before you install a module in the other connector.
NOTE: Memory purchased from Dell is covered under your computer warranty.
Installing Memory
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.
CAUTION: 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.

Align the notch on the bottom of the module with the crossbar in the connector.
NOTICE: To avoid damage to the memory module, press the module straight down into the connector
while you apply equal force to each end of the module.
Insert the module into the connector until the module snaps into position.
If you insert the module correctly, the securing clips snap into the cutouts at each end of the module.
Replace the computer cover.
NOTICE: To connect a network cable, first plug the cable into the network wall jack and then plug it into
the computer.
Connect your computer and devices to electrical outlets, and turn them on.
After you open and close the cover, the chassis intrusion detector, if enabled, causes the following message to appear on the screen at the next computer start-up:
NOTE: If an admin password has been assigned by someone else, contact your network administrator for
information on resetting the chassis intrusion detector.
The computer detects that the new memory does not match the existing configuration
information and generates the following message:
The amount of system memory has changed.
Strike the F1 key to continue, F2 to run the setup utility
Press <F2> to enter system setup and check the value for System Memory.
The computer should have changed the value of System Memory to reflect the newly installed memory capacity, speed, and mode (single or dual). Verify that the information is correct. If it is correct, skip to step 11.
If the memory total is incorrect, turn off and disconnect your computer and devices from
their electrical outlets. Open the computer cover and check the installed memory modules to
ensure that they are seated properly in their sockets. Then repeat steps 5, 6, and 7.
When the System Memory total is correct, press <Esc> to exit system setup.
Run the Dell Diagnostics to verify that the memory modules are operating properly.
Removing Memory
