Inspiron 530sb/530sd • DIMM connectors must be populated in numerical order beginning with connector DIMM_1, then connector DIMM_2. If a single DIMM is installed, you must install it in connector DIMM_1. 1 1 Pair A: matched pair of memory modules in connector DIMM_1 and DIMM_2 For best performance, memory modules should be installed in pairs of matched memory size, speed, and technology. If the memory modules are not installed in matched pairs, the computer will operate, but with a slight reduction in performance. (See the label on the module to determine the module's capacity.) For example, if you install a mixed pair of DDR2 667-MHz and DDR2 800-MHz memory, the modules function at the slowest speed installed. 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. You should install your original memory modules in pairs either in: DIMM connectors 1 and 3 or DIMM connectors 2 and 4 (not applicable for 530sb/530sd). NOTE: Memory purchased from Dell is covered under your computer warranty. 124 Removing and Installing Parts
