DIMM Module Population Sequence
When installing memory modules, the DIMM slots should be populated in the following order:
DIMMA2, then DIMMB2, DIMMA1, and then DIMMB1.
•
Always use DDR4 DIMM modules of the same 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 (one or three modules installed).
However, for best memory performance, install DIMM modules in pairs to activate memory
interleaving.
