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 t wo 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 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://www.dell.com/
