Figure 3-12. DIMM Numbering
DIMM Module Population
When populating the motherboard with DIMM modules, please keep in mind the following:
•
Always use DDR4 DIMM modules of the same type, size and speed.
•
All eight memory channels per CPU socket should be populated with each channel having
equal capacity. This enables the memory subsystem to operate in eight-way interleaving
mode, which should provide the best performance in most cases.
•
In most configurations, populating fewer than eight channels is supported, but not recom

mended.
*Note: Most configurations populating fewer than eight channels are supported, but not recommended.
