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 damage.

Memory Support

The X11DPFR-S(N) supports up to 1.5TB of LRDIMM, Registered DIMM (RDIMM), and Non-
Volatile DIMM (NV-DIMM) DDR4 (288-pin) ECC 2666/2400/2133 MHz modules in 12 slots.
Populating these DIMM modules with a pair of memory modules of the same type and size
will result in interleaved memory, which will improve memory performance.
Notes: 1. Be sure to use the memory modules of the same type and speed on the
motherboard. Mixing of memory modules of different types and speeds is not allowed.
2. When installing memory modules, be sure to populate the first DIMM module on
the blue memory slot, which is the first memory slot of a memory channel, and then
populate the second DIMM in the black slot if 2DPC memory configuration is used. 3.
Using unbalanced memory topology by populating two DIMMs in one channel while
populating one DIMM in another channel will result in reduced memory performance.
