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 X11SSH-F/-LN4F motherboard supports up to 64GB of unbuffered (UDIMM) DDR4 ECC
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 table below when populating memory.
