•
For each individual population, rearrangements between channels are allowed as long as the resulting population is
compliant with the Supermicro X11OPx/X11QPx/X11DPx/X11SPx memory population rules for the 2nd Gen Intel Xeon
Scalable-SP (82xx/62xx/52xx/4215 series) processors.
•
For each individual population, please use the same DDR4 DIMM in all slots.
•
For each individual population, sockets are normally symmetric with exceptions for 1 DCPMM per socket and 1 DCPMM
per node case. Currently, DCPMM modules operate at 2666 MHz.
•
No mixing of DCPMM and NVMDIMMs within the same platform is allowed.
•
This DCPMM population guide targets a balanced DCPMM-to-DRAM-cache ratio in MM and MM + AD modes.
