Optane PMem Notes
•
PMem is supported by the Intel Xeon Scalable Processors Platinum, Gold and selected
Silver processors only
•
Matrix targets configs for optimized PMem to DRAM cache ratio in MM and MM + AD
modes.
•
For each individual population, different PMem rearrangements among channels are per
-
mitted so long as the configuration does not break X12 DP Memory population rules.
•
Ensure the same DDR4 DIMM type and capacity are used for each DDR4 + PMem popu-
lation.
•
If the system detects an unvalidated config, then the system issues a BIOS warning. The
CLI functionality is limited in non-POR configurations, and select commands will not be
supported.
