Intel Optane PMem 200 Series Memory Population Table (with 16 Slots)
Note: Only 83xx/63xx/53xx processors support PMem 200 Series.

Mode definitions: AD = App Direct Mode, MM = Memory Mode.
•
No mixing of 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 mode.
•
For each individual population, different PMem rearrangements among channels are permitted ast long as the
configuration doesn't break X12 DP Memory population rules.
•
Ensure the same DDR4 DIMM type and capacity are used for each DDR4 + PMem population.
•
If the system detects an unvalidated configuration, then the system issues a BIOS warning. The CLI functionality is
limited in non-POR configurations, and select commands will not be supported.
