RANKOFFSET
Rank Offset for calculating RANK. This corresponds to the first logical rank on
Rank Offset for calculating RANK. This corresponds to the first logical rank on
the DIMM. The rank offset is always programmed to 0 for the DIMM 0 DOD
registers. (DIMM 0 rank offset is always 0.) DIMM 1 DOD rank offset is 4 for
two DIMMs per channel or 2 if there are three DIMMs per channel. DIMM2
DOD rank offset is always 4 as it is only used in three DIMMs per channel
case.
