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.

Independent memory mode guidelines:
  • Mixing x4/x8, 16Gbit (16GB, 32GB, 64GB)/24Gbit (48GB, 96GB) DIMMs are not allowed in a system.

  • When installing DIMMs with different capacities, install the DIMM with the highest capacity first, and install the DIMMs in the following sequence: Slot 3, 4, 1, 6, 2, 5.
