Notes
: DDR4 single rank x8 is not available for DCPMM Memory Mode or App Direct Mode.
CPU1 and CPU2 should be populated identically.

Any Capacity (Uniformly for all channels for a given configuration)
•
For MM, the general NM/FM ratio is between 1:4 and 1:16. Excessive capacity for FM can be used for AD. (NM = Near
Memory; FM = Far Memory)
•
For each individual population, rearrangements between channels are allowed as long as the resulting population is compliant
with the PDG rules for the 82xx/62xx/52xx platform.
•
For each individual population, please use the same DDR4 DIMM in all slots as specified by the PDG rules.
•
For each individual population, sockets are normally symmetric with exceptions for 1 DCPMM per socket and 1 DCPMM
per node case. Currently, DCPMM modules operate at 2666 MHz.
•
No mixing of DCPMM and NVMDIMMs within the same platform is allowed.
•
This DCPMM population guide targets a balanced DCPMM-to-DRAM-cache ratio in MM and MM + AD modes.
