Pmem Population For The X12Dxx Motherboards - Supermicro Optane Persistent Memory 200 Series User Manual

2.4 PMem Population for the X12Dxx Motherboards

These memory population tables were created based on the general memory population
guidelines provided by Intel to support Supermicro X12Dxx motherboards.
PMem 200 Series Population Table for X12Dxx Motherboards (with 16 Slots)
Note: PMem 200 Series is supported by the 3rd Gen Intel Xeon Scalable
(83xx/63xx/53xx/4314 Series) Processors.

•
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. (NM = Near Memory (DRAM); FM = Far Memory (PMem)).
•
Matrix targets configs for optimized PMem to DRAM cache ratio in MM mode.
•
For each individual population, different PMem rearrangements among channels are permitted so long as the
configuration doesn't break X12Dxx 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.
