Memory Installation
Memory Support
The motherboard features four DIMM slots that can support up to 64 GB of of unbuffered,
ECC/non-ECC DDR4 with speeds up to 2666MHz memory. Check the Supermicro website
for possible updates to memory support.
Memory Population Guidelines
•
All DIMMs must be DDR4.
•
Balance memory. Using unbalanced memory topology, such as populating two DIMMs in
one channel while populating one DIMM in another channel, reduces performance. It is
not recommended for Supermicro systems.
Guidelines Regarding Mixing DIMMs
•
Populating slots with a pair of DIMM modules of the same type and size results in inter-
leaved memory, which improves memory performance.
•
Use memory modules of the same type and speed, as mixing is not allowed.
•
x4 and x8 DIMMs can be mixed in the same channel.
Memory Population Sequence
Slots should be populated in the following order: DIMMA2, DIMMB2, DIMMA1, and DIMMB1.
