Memory Support
The X11DDW-L supports up to 3TB of Load Reduced DIMM (LRDIMM), Registered DIMM
(RDIMM), and Non-Volatile DIMM (NV-DIMM) 288-pin, ECC DDR4-2933 memory 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. Note that 2933 MHz
memory is supported by the 82xx/62xx/52xx platform only. Only Platinum-level and Gold-level
processors support Intel Optane
TM
DC Persistent Memory Module (DCPMM).
Notes:
unbalanced memory topology by installing two DIMMs in one channel while installing one
DIMM in another channel will result in reduced memory performance. 3. Memory speed is
dependent on the type of processors used in your system.
