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. 2 1 1 Pair A: matched pair of memory 2 Pair B: matched pair of memory modules in connectors DIMM_1 and modules in connectors DIMM_3 and DIMM_2 DIMM_4 104 Memory Module(s)
