Note: DDR4 single rank x8 is not available for Intel Optane PMem Memory Mode or App-Direct Mode.
•
* 2nd socket has no Intel Optane PMem DIMM
•
Mode definitions: AD=App Direct Mode, MM=Memory Mode, AD+MM=Mixed Mode
•
For MM, general DDR4+Intel Optane PMem ratio is between 1:4 and 1:16. Excessive capacity for Optane PMem can
be used for AD.
•
For each individual population, rearrangements between channels are allowed as long as the resulting population is
compliant with the X11 memory population rules for the 2nd Gen Intel Xeon Scalable-SP 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 one Intel Optane PMem per socket
and one Intel Optane PMem per node case. Currently, Intel Optane PMem modules operate at 2666 MHz.
•
No mixing of Intel Optane PMem and NVMDIMMs within the same platform is allowed.
•
This Intel Optane PMem population guide targets a balanced Optane PMem-to-DRAM-cache ratio in MM and MM +
AD modes.
