General Memory Module Installation Guidelines - PowerEdge M910

To ensure optimal performance of your system, observe the following general

guidelines when configuring your system memory:

• Memory modules must be installed in pairs, beginning with the first two

sockets in each set of memory modules. These sockets are marked by white

retention levers.

• The memory configuration for each processor must be identical.
• Memory modules must be identical in size, speed, and technology in

lock

step pair (same colored levers).

• If quad-rank memory modules are mixed with single- or dual-rank

modules, the quad-rank modules must be installed in the sockets with the

white release levers.

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

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

• Memory mirroring and memory sparing are supported only if 32 memory

modules are installed.
