13.2.4.11 DIMM_TEMP_TH_[0:2]
13.2.4.12 DIMM_TEMP_THRT_LMT_[0:2]
All three THRT_CRIT, THRT_HI and THRT_MID are per DIMM BW limit, that is, all 
activities (ACT, READ, WRITE) from all ranks within a DIMM are tracked together in one 
DIMM activity counter.

TEMP_THRT_HYST (temp_thrt_hyst):
Positive going Threshold Hysteresis Value. Set to 00h if sensor does not support 
positive-going threshold hysteresis. This value is subtracted from 
TEMP_THRT_XX to determine the point where the asserted status for that 
threshold will clear.

TEMP_HI (temp_hi):
TCase threshold at which to Initiate THRTCRIT and assert THERMTRIP# valid 
range: 32 to 127°C. Note: the default value is listed in decimal.
FF: Disabled
