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, 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 for Vostro 420 are:

1)A pair of matched memory modules installed in DIMM connectors 1 and 2, or

2)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 modules, the modules function at the speed of the slowest module installed.

NOTE: 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.

NOTE: Vostro 420 can accommodate four DIMMs; Vostro 220 and Vostro 220s can accommodate two DIMMs.
