Re: Mixing Different Rank DIMMS in DL380 G9 server

You can find the Iformation in the QuickSpecs:

Populate DIMMs from heaviest load (quad-rank) to lightest load (single-rank) within a channel. Heaviest load (DIMM with most ranks) within a channel goes furthest from the processor.
Do not mix RDIMMs or LRDIMMs.
LRDIMMs are supported up to 3 DIMMs per channel.
DIMMs of different speeds may be mixed in any order; the server will select a common optimal speed.

And you can also check your Configuration here;
