DIMM Module Population
When populating the motherboard with DIMM modules, please keep in mind the following:
•
Always use DDR5 DIMM modules of the same type, size and speed.
•
All six memory channels should be populated with each channel having equal capacity,
which should provide the best performance in most cases.
•
In most configurations, populating fewer than six channels is supported, but not recom-
mended.
