Dell EMC E39S Series Installation And Service Manual page 95

• 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
