PMem Notes
•
Memory slots P1-DIMMB2 and P2-DIMMB2 are reserved for PMem 200 Series 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.

Note:
The Intel Optane Persistent (PMem) 200 Series are supported by the 3rd Gen.
Intel Xeon Scalable (83xx/63xx/53xx/4314) processors.
