Independent memory mode installation order

In independent memory mode, memory channels can be populated with DIMMs in any order and you can populate all channels for each processor in any order with no matching requirements. Independent memory mode provides the highest level of memory performance, but lacks failover protection. The DIMM installation order for independent memory mode varies based on the number of processors and memory modules installed in the server.

Follow the rules below when installing memory modules in independent mode:

  • There should be at least one DDR5 DIMM per processor.

  • Populate memory channel 0 first.

  • In each memory channel, populate slot 0 first.

  • Memory modules from different vendors are supported

  • All memory modules to be installed must be the same capacity and same speed.
