PowerEdge 11th Generation Servers: R810, R910, and M910 Memory Guidance
Good Performance
2 DIMMS per Memory Buffer Channel, all memory controllers populated equally with 32 DIMMs and 4 Memory Risers (R910), lower maximum bandwidth, higher latency
1 DIMM per Memory Buffer Channel, all memory controllers populated equally with 16 DIMMs and 4 Memory Risers (R910), lower maximum bandwidth, higher latency
Note: Mixed DIMM capacity is supported. The recommendation is to populate memory controllers equally and always pair DIMMs identically.
