General Memory Population Requirements
1. Be sure to use the memory modules of the same type and speed on the motherboard.
Mixing of memory modules of different types and speeds is not allowed.
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.
3. 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.
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
•
All DIMMs must be all DDR4 DIMMs.
•
x4 and x8 DIMMs can be mixed in the same channel.
•
Mixing of LRDIMMs and RDIMMs is not allowed in the same channel, across different
channels, and across different sockets.
•
Mixing of non-3DS and 3DS LRDIMM is not allowed in the same channel, across
different channels, and across different sockets.

Note: Unbalanced memory configuration decreases memory performance and is not
recommended for Supermicro motherboards.
