The X11SPA-TF/X11SPA-T motherboard supports an Intel® Xeon® Scalable-SP or 2nd Generation Intel Xeon
Scalable-SP processor, up to 768GB of ECC RDIMM, 3TB of 3DS RDIMM, 1.5TB of LRDIMM, and 3TB of 3DS
LRDIMM DDR4 (288-pin) ECC memory with speeds of up to 2933MHz (2DPC) in twelve 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. (1DPC and 2DPC are recommended for memory installation. Only selected 2nd
Gen Intel Xeon Scalable-SP processors support Intel Optane™ DC Persistent Memory Modules.)
Notes: 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.
