Memory Guidelines

•
Always use DDR4 DIMM modules of the same type, size and speed.
•
Memory channels should be populated with each channel having equal capacity. This
enables the memory subsystem to operate in interleaving mode, which provides the best
performance.
•
In most configurations, populating fewer than eight channels is supported, but not recom-
mended.
