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 X11SSA-F/X11SSi-LN4F motherboard supports up to 64GB of unbuffered (UDIMM)
DDR4 ECC 2400/2133/1866/1600/1333MHz memory in four memory slots. Populating these
DIMM slots with memory modules of the same type and size will result in interleaved memory,
which will improve memory performance.

DIMM Module Population Configuration

For optimal memory performance, follow the tables below when populating memory.
