DCPMM installation guidelines
The following are the recommended guidelines for installing data center persistent memory module (DCPMM) memory modules:
●
Each system supports maximum of one DCPMM memory module per channel.
NOTE:
If two different DCPMM capacities are mixed, an F1/F2 warning is displayed as the configuration is not
supported.
●
DCPMM can be mixed with RDIMM, LRDIMM, and 3DS LRDIMM.
●
Mixing of DDR4 DIMM types (RDIMM, LRDIMM, and 3DS LRDIMM), within channels, for Integrated Memory Controller
(iMC), or across sockets are not supported.
●
Mixing of DCPMM operating modes (App Direct, Memory Mode) is not supported.
●
If only one DIMM is populated on a channel, it should always go to the first slot in that channel (white slot).
●
If a DCPMM and a DDR4 DIMM are populated on the same channel, always plug DCPMM on second slot (black slot).
●
If the DCPMM is configured in Memory Mode, the recommended DDR4 to DCPMM capacity ratio is 1:4 to 1:16 per iMC.
●
DCPMMs' cannot be mixed with other DCPMMs capacities or NVDIMMs.
●
Mixing different capacities of RDIMMs and LRDIMMs are not allowed when DCPMM is installed.
●
DCPMMs of different capacities are not allowed.
