The X11SCA/X11SCA-F/X11SCA-W motherboard supports a single Intel

series processor, up to 128GB of Unbuffered (UDIMM) ECC/Non-ECC DDR4 memory, and up to 2666MHz in four
288-pin 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
: 1) For memory optimization, use only DIMM modules that have been validated by Supermicro. For the latest memory updates, please
refer to our website at http://www.supermicro.com/products/motherboard.
2) Always connect the power cord last, and always remove it before adding, removing or changing any hardware components.

Memory Population Guidelines
•
Always use DDR4 DIMM modules of the same size, type, and speed.
•
Mixed DIMM speeds can be installed. However, all DIMMs will run at the speed of the slowest DIMM.
