Identifying The Processor Type; Installing A Dimm - HP ProLiant DL180 Gen9 User Manual

•
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.
