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.
