General Memory Module Installation Guidelines – PowerEdge M605

To ensure optimal performance of your system, observe the following

guidelines when installing your system memory:

• Memory modules must be installed in pairs of identically-sized DIMMs,

beginning with slots A1 and A2 (processor 1) and B1 and B2 (processor 2, if

installed). These slots are marked by white ejector tabs.

• All memory modules in the blade must be identical in speed and

technology. The memory modules in each pair must be the same size.

• In two-processor configurations, memory must be installed in the same

configuration (symmetrically) for both processors.

• If pairs of memory modules of different sizes are installed, the larger

capacity memory modules must be installed in the lower numbered slots.

• Memory sparing is supported if four (single-processor systems) or eight

(dual-processor systems) memory modules are installed.

Table 3-11 and Table 3-12 show examples of supported single- and dual-

processor memory configurations.
