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 3-10 and Table 3-11 show examples of supported single- and dual-
processor memory configurations.
