DIMM Module Population Sequence
When installing memory modules, the DIMM slots must be populated in the following order:
DIMMA2, DIMMB2, DIMMA1, and DIMMB1.
•
Always use DDR4 memory of the same type, size 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,
to achieve the best memory performance, a balanced memory population is recommended.
