Closed Loop Activation Throttling Policy
Individual DIMMs flag their thermal state in the FB-DIMM status return. When the
MC.THRMHUNT configuration bit is set, memory reads and writes (summed together)
will be regulated on a per-DIMM-pair basis according to the following algorithm
described in
degree of thermal throttling if there is a sudden temperature spike between from T
to T
MC.THRMODE=0. Once this point is reached, if temperature increased further during
the next global window, then THRMTHRT register will be adjusted by the equation
THRMTHRT= MAX(THRMTHRT -2, THRTHI). See staircase effect in
