DIMM Module Population Sequence
When installing memory modules, the DIMM slots should be populated in the following
order: DIMMA2, DIMMB2, DIMMC2, DIMMD2, DIMME2, DIMMF2, DIMMG2, DIMMH2, then
DIMMA1, DIMMB1, DIMMC1, DIMMD1, DIMME1, DIMMF1, DIMMG1, DIMMH1.

• 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, fully populate the motherboard with validated
memory modules.
