Memory Support
The X11SRA motherboard supports up to 256 GB of RDIMM or 512 GB of LRDIMM ECC/
Non-ECC DDR4 memory with speeds of up to 2666 MHz in eight memory slots. Populating
the DIMM slots in a 2DPC (two DIMMs per channel) configuration with pairs of memory
modules of the same type, speed and size will result in interleaved memory, which improves
performance. Mixed DIMM speeds can be installed, however, all DIMMs will run at the speed
of the slowest DIMM.
Check the Supermicro website for possible updates to memory support (
