General Memory Module Installation Guidelines – PowerEdge M600
To ensure optimal performance of your system, observe the following
guidelines when configuring your system memory:
• Memory modules must be installed in pairs of identically-sized DIMMs.
The total number of memory modules must equal two, four, or eight.
Six modules are not supported.
• All memory modules in the blade must be identical in speed and
technology. The memory modules in each pair must be the same size.
For best system performance, all memory modules should be identical
memory size, speed, and technology.
•Memory sp
aring and memory m irroring require eight memory module s of
identical size, speed, and technology.
Memory sparing and memory mirroring cannot be implemented at the
same time.
Table 3-14 shows examples of supported memory configurations.
CAUTION: Memory module blanks must be installed in unoccupied memory
sockets to maintain proper cooling airflow.
