DIMM Module Population Sequence

When installing memory modules, the DIMM slots should be populated in the following order:
DIMMA2, DIMMB2, DIMMA1, DIMMB1.
•
Always use DDR4 DIMM modules of the same type and size.
•
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 interleav-
ing.
