Memory Support

The X11DAi-N supports up to 2048 GB of Load Reduced DIMM (LRDIMM), Registered DIMM
(RDIMM), Non-Volatile DIMM (NV-DIMM) DDR4 (288-pin) ECC 2133/2400/2666 MHz memory
modules in 16 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. Use the memory modules of the same type and speed. Mixing memory modules of
different types and speeds is not allowed. 2. When installing memory modules, be sure to install
the first DIMM module in the blue memory slot, which is the first slot of a memory channel, and
then install 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.
