10.2.2 Memory population conditions
●
Non-ECC DIMMs are not supported on this platform.
●
All DIMMs must be either all DDR4 DIMMs and/or DDR4 and DCPMMs.
●
x4 and x8 DIMMs cannot be mixed in any channel.
●
Mixing of LRDIMM with RDIMM type is not allowed per platform.
●
Mixing of non-3DS and 3DS LRDIMMs is not allowed in the same channel,
across dif
ferent channels, and across different sockets.
●
Mixing of DCPMMs with RDIMMs is supported in Purley platform.
●
Mixing of DCPMMs with LRDIMMs is supported in Purley platform.
●
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 (slot 1A/1G).
●
If two DIMMs with different capacity are installed in one channel, the DIMM
with the higher capacity has to be placed in slot 1 of a channel, e.g. 1A, 1B.
●
If DIMMs with different ranks are installed in one channel, the DIMM with the
higher rank has to be placed in slot 1 of a channel, e.g. 1A, 1B.
