Replacing or Adding a Memory Module
NOTICE: Do not install ECC memory modules.
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. 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.
NOTE: If you install mixed pairs of PC2-5300 (DDR2 667-MHz) and PC2-6400 (DDR2 800-MHz) memory, the modules function at the speed of the slowest module installed.
Ensure that you install a single memory module in DIMM connector 1, the
connector closest to the processor, before you install modules in any other
connector.
