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-H-TP4F/TF supports up to 256GB RDIMM or 64GB UDIMM DDR4 ECC/Non
ECC 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.

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
