When single-rank, dual-rank, and quad-rank DIMMs are populated for two DIMMs per channel, always
populate the higher number rank DIMM first (starting from the farthest slot). For example, first quad-rank
DIMM, then dual-rank DIMM, and then lastly single-rank DIMM.
•
DIMMs should be populated starting farthest from the processor on each channel.
