DIMM Module Population Sequence
When installing memory modules, the DIMM slots should be populated in the following order:
DIMMA1, DIMMD1, DIMMB1, DIMME1, DIMMC1, DIMMF1, DIMMA2, DIMMD2.
•
The blue slots must be populated first.
•
Only populate DIMMA2 and DIMMD2 if the extra memory support is needed.
•
Always use DDR4 DIMM modules 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.
