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.
DDR Memory Overview
See the label in the upper-right corner of the module to determine the module's capacity.
NOTE: Always install DDR memory modules in the order indicated on the system board.
The recommended memory configurations are:
A memory module installed in connector DIMM_A
or
A pair of matched memory modules installed in connectors DIMM_A and DIMM_B
NOTICE: Do not install ECC memory modules.
If you install mixed pairs of PC2100 (DDR 266-MHz) and PC2700 (DDR 333-MHz) memory, the modules function at the slowest speed installed.
Be sure to install a single memory module in DIMM_A, the connector closest to the processor, before you install modules in the other connector(s).
The actual speed of the SDRAM memory channel will depend on the speed of the processor's front side bus.
Installing Memory
CAUTION: Before you begin any of the procedures in this section, follow
the safety instructions.
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.

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.
Close the computer cover.
Attach the computer stand, if it is used.
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 a setup 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. Verify the new total. If it is correct, skip to step 12.
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.
