PMem Notes
•
PMem 200 Series are supported on 3rd gen Intel Xeon Scalable Platinum, Gold and se-
lected Silver processors.
•
Do not mix PMem and NVDIMMs within the platform.
•
For MM, NM/FM ratio is between 1:4 and 1:16. The capacity not used for FM can be used
for AD. (NM = Near Memory; FM = Far Memory).
•
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
permitted 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.
•
x4 and x8 DDR4 DIMMs cannot be mixed in the same channel in PMem configurations.
