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 X11SAE-M supports up to 64 GB of DDR4 ECC/Non-ECC UDIMM memory up to
2133MHz in four memory slots. 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: Be sure to use memory modules of the same type and speed on the motherboard.
Mixing of memory modules of different types and speeds is not allowed.
DIMM Module Population Conguration
For optimal memory performance, follow the table below when populating memory.
