Memory Installation Guidelines

•DIMM connectors must be populated in numerical order beginning with connectors DIMM_1 and DIMM_3, then connectors DIMM_2 and DIMM_4.

If a single DIMM is installed, you must install it in connector DIMM_1.

•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 533-MHz and DDR2 667-MHz and 800 MHz memory, the modules function at the slowest speed installed.
