For additional information on the type of memory supported by your computer, see "Specifications" on page 87. DDR2 Memory Overview DDR2 memory modules should be installed in pairs of matched memory size, speed, and technology. If the DDR2 memory modules are not installed in matched pairs, the computer will continue to operate, but with a slight reduction in performance. See the label on the module to determine the module's capacity. NOTE: Always install DDR2 memory modules in the order indicated on the system board. The recommended memory configuration consists of a pair of matched memory modules installed in DIMM connectors 1 and 2 NOTICE: Do not install ECC or buffered memory modules. Only unbuffered, non-ECC memory is supported. · · If you install mixed pairs of DDR2 400-MHz (PC2-3200) and DDR2 533-MHz (PC2-4300) memory, the modules function at the slower installed speed. Be sure to install a single memory module in DIMM connector 1, the connector closer to the processor, before you install a module in the other connector. 62 Removing and Installing Parts 1 2 matched pair of memory modules in DIMM connectors 1 and 2 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.
