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 X10SRA (-F) supports up to 512GB of ECC LRDIMM, up to 2133MHz,

or 256GB ECC RDIMM, up to 2133Mhz, or up to 64GB ECC/Non-ECC

Unbuf fered UDIMM (for Core i7 only), up to 2133MHz, in 8 memor y slot s.

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
