Memory Support
The A2SD1-3750F/3955F supports up to 128GB of ECC VLP RDIMM and 64GB of ECC VLP
UDIMM DDR4 memory with speeds of up to 2400MHz. 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.
Note
: Check the Supermicro website for recommended memory modules.
Caution:
Exercise extreme care when installing or removing DIMM modules to prevent any
possible damage.
Memory Population Guidelines
For optimal memory performance, follow the table below when populating memory. Populate
DIMM slots in the following order: DIMMA2, DIMMB2, then DIMMA1 and DIMMB1.
