RIR_RNK_TGT3
Target rank ID for rank interleave 3 (used for 1/2/4/8-way RIR interleaving).
15 RV 0h Reserved
14:2 RW-LB 0h
RIR_OFFSET3
RIR[5:0].RANKOFFSET3[38:26] == rank interleave 3 offset, 64 MB granularity
(processor’s minimum rank size is 512 MB. 512 MB/8 interleave = 64 MB per 8-
way interleave.)
