7.63 DDR—Offset 58B4h
Per-DIMM temperature values.
Access Method
Default: 0h
7.64 DDR—Offset 58C0h
Per-DIMM throttle duration counters. These accumulate the duration (in absolute wall
clock time) that the iMC rank throttlers have been blocking memory traffic due to
OLTM/CLTM/EXTTS thermal status. Note that RAPL throttling is done at the channel
level, and thus is NOT included in these values.
Access Method
Default: 0h
Type: MEM
(Size: 32 bits)
Offset: [B:0, D:0, F:0] + 58B4h
