Figure 3-2. Populating DIMM Slots
DIMM Module Population Sequence
When installing memory modules, the DIMM slots should be populated in the following order:
DIMMA1, DIMMB1, DIMMA2, DIMMB2.
•
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,
for best memory performance, install DIMM modules in pairs to activate memory interleav-
ing.
