Memory Population Guidelines - Supermicro X9SRW-F User Manual

Memory Population Guidelines

When installing memory modules, the DIMM slots should be populated in the follow-
ing order: DIMMA1, DIMMB1, DIMMC1, DIMMD1 then DIMMA2, DIMMB2, DIMMC2,
DIMMD2. Populate the blue-colored slots first.
• Always use DDR3 DIMM modules of the same size, type and speed.
• Mixed DIMM speeds can be installed. However, all DIMMs will run at the speed
of the slowest DIMM.
• The motherboard will support odd-numbered modules installed (1 ,3 ,5 ,or 7 mod-
ules). However, for best memory performance, install DIMM modules in pairs.
