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.
