DCPMM Support Location
Symmetric Population within the Socket
Asymmetric Population within the Socket
* 2
nd
socket has no DCPMM DIMM
Mode definitions: 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 consistent to Purley PDG rules
For each individual population, the same DDR4 DIMM has to used in all slots,
as specified by the Purley PDG rules
For each individual population, sockets are normally symmetric with exceptions
for 1 DCPMM per socket and 1 DCPMM per node case.
Any Capacity and Preferably, >=32GB
