– Non-ECC DIMMs are not supported on this platform.
– 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 LRDIMMs is not allowed per platform.
– DIMMs with different frequencies can be mixed in the system.
– 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.
– If DIMMs with different ranks are installed on one CPU socket, follow
memory module population order.
