Memory population conditions

– Non-ECC DIMMs are not supported on this platform.
– All DIMMs must be either all DDR4 DIMMs or DDR4 and Optane PMem
modules.
– x4 and x8 DIMMs cannot be mixed in the same channel.
– Mixing of LRDIMM with RDIMM type is not allowed per platform.
– Mixing of non-3DS and 3DS RDIMMs is not allowed per platform.
– Mixing of Optane PMem modules with RDIMMs is supported is allowed.
– Mixing of Optane PMem modules with LRDIMMs is supported is allowed.
– DIMMs with different frequencies can be mixed in the system, but lowest
frequency determines the system memory speed.
– There should be at least one DDR4 DIMM per CPU socket.
– If only one DIMM is populated in a channel, then populate it in the slot
furthest away from CPU.
– Mixing Optane PMem module capacities or generations or DDR4 DIMM
capacities and types within a socket or across sockets is not supported for
Optane PMem module configurations.
– When different rank DIMMs are populated for 2DPC, always populate the
higher number rank DIMM first (starting from the black slot), for example,
first octal rank, then quad rank, then dual rank, and last single rank DIMM.
