General Memory Population Requirements
1. Be sure to use the memory modules of the same type and speed on the motherboard.
2. Using unbalanced memory topology such as populating two DIMMs in one channel while
populating one DIMM in another channel on the same motherboard will result in reduced
memory performance.
Populating memory slots with a pair of DIMM modules of the same type and size will result in
interleaved memory, which will improve memory performance.Check the Supermicro website
for possible updates to memory support.
DIMM Population Guidelines for Optimal Performance
For optimal memory performance, follow the instructions listed in the tables below when
populating memory modules.

DIMM Mixing Guidelines
General DIMM Mixing Guidelines
• All DIMMs must be all DDR4 DIMMs.
• x4 and x8 DIMMs can be mixed in the same channel.
•
• Mixing of non-3DS and 3DS LRDIMM is not allowed in the same channel, across
Mixing of DIMM Types within a Channel
