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.
