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:
• Individual memory channels can run at different DIMM timings, but all channels must run at the same
interface frequency.
• Populate memory channel 0 first.
• Memory channel 1 is empty or identically populated as memory channel 0.
• Memory channel 2 is empty or identically populated as memory channel 1.
• In each memory channel, populate slot 0 first.
• If a memory channel has two DIMMs, populate the DIMM with a higher number of ranks in slot 0.
