When two memory modules with a different number of ranks are populated in one memory
i
channel, then the module with the higher number of ranks must be populated in the
memory slot further away from the CPU.
If the system is upgraded and an additional memory module is added to a channel with an
existing module, it might be necessary to swap modules so that the module with the higher
number of ranks is populated on the outside (further away from the CPU) of that memory
channel.
