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.
For more information about the supported DCPMM configurations, see the Dell EMC DCPMM User 's Guide at https://
