For information on the type of memory supported by your computer, look under "Memory" in the "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
DDR memory modules should be installed in pairs of matched memory size, speed, and technology. If the DDR memory modules are not installed in matched pairs, the computer will continue to operate, but with a slight reduction in performance.
NOTE: DDR400 memory runs at 333 MHz when configured with
533-MHz FSB processors.
NOTE: DDR333 memory runs at 320 MHz when configured with Pentium 4 800-MHz FSB processors.
NOTICE: Do not install ECC memory modules.
If you install a mixed pair of PC2700 (DDR 333-MHz) and PC3200 (DDR 400-MHz) memory, the modules function at the slowest speed installed.
Be sure to install a single memory module in DIMM1, the connector closest to the processor, before you install modules in the other connectors.
The actual speed of the SDRAM memory channel will depend on the speed of the processor's front side bus.
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.
Installing Memory
CAUTION: Before you begin this procedure, follow the safety instructions in the
Product Information Guide.
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.
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 10.
If the memory total is incorrect, turn off and disconnect your computer and devices from
their electrical outlets. Remove the computer cover and check the installed memory modules
to ensure that they are seated properly in their sockets. Then repeat steps 5
through 8.
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
CAUTION: Before you begin this procedure, follow the safety instructions in the
Product Information Guide.
