Memory Population Guidelines

When installing memory modules, the DIMM slots should be populated in the following
order: DIMMA1, DIMMB1 then DIMMA2, DIMMB2
• 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 (1 or 3 modules installed).
However, for best memory performance, install DIMM modules in pairs to activate
memory interleaving.
