Capacity
DCPMM Any Capacity (Uniformly for all channels for a given con fi guration)
•
* 2nd socket has no DCPMM DIMM
•
Mode de fi nitions: AD=App Direct Mode, MM=Memory Mode, AD+MM=Mixed Mode
•
For MM, general DDR4+DCPMM ratio is between 1:4 and 1:16. Excessive capacity for DCPMM can be used for AD.
•
For each individual population, rearrangements between channels are allowed as long as the resulting population is
compliant with the memory rules for 2nd Gen Intel Xeon Scalable-SP (82xx/62xx/52xx/4215 series) processors.
•
For each individual population, please use the same DDR4 DIMM in all slots.
•
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.
Note: Only 2nd Gen Intel Xeon Scalable-SP (82xx/62xx/52xx/4215 series) processors
support DCPMM memory.
