Notes: DDR4 single rank x8 is not available for DCPMM Memory Mode or App Direct Mode.
CPU1 and CPU2 should be populated identically.
AD: App Direct, MM: Memory Mode
Capacity
DCPMM Any Capacity (Uniformly for all channels for a given conguration)
• 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 specied
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.
