Memory Population Guidelines
When installing memory modules, the DIMM slots should be populated in
the following order: DIMMA1, DIMMB1, DIMMC1, DIMMD1 then DIMMA2,
DIMMB2, DIMMC2, DIMMD2.
• Always use DDR4 DIMM modules of the same size, type and speed.

The C7X99-OCE(-F) supports up to 64GB of Unbuffered (UDIMM) DDR4
non-ECC 2133~3000(OC) MHz in 8 memory slots. Populating these
DIMM modules with a pair of memory modules of the same type and
same size will result in interleaved memory, which will improve memory
performance.
Note: For memory optimization, use only DIMM modules that have been
validated by Supermicro. For the latest memory updates, please refer
