General Memory Module Installation Guidelines – PowerEdge M805
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. 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.
