2.4 Memory Support and Installation
Note: Check the Supermicro website for recommended memory modules.
Important: Exercise extreme care when installing or removing DIMM modules to pre-
vent any possible damage.
Memory Support
The A2SDi-2C-HLN4F supports up to 128GB RDIMM or 32GB ECC/Non-ECC UDIMM DDR4
in two memory slots, two DIMM on single channel at up to 1866MT/s .
The A2SDi-4C-HLN4F support up to 256GB RDIMM or 64GB ECC/Non-ECC UDIMM DDR4
in four memory slots, two DIMM Per Channel (DPC) at up to 2133MT/s.
The A2SDi-8C/8C+/12C/16C-HLN4F support up to 256GB RDIMM or 64GB ECC/Non-ECC
UDIMM DDR4 in four memory slots, two DIMM Per Channel (DPC) at up to 2400MT/s.
Populating these DIMM slots with a pair of memory modules of the same type and size will
result in interleaved memory, which will improve memory performance.
Memory Population Guidelines
For optimal memory performance, follow the table below when populating memory. Populate
DIMM slots in the following order: DIMMA1, DIMMB1, then DIMMA2, DIMMB2
