... The Intel 5000P Chipset MCH will use an internal signal called GBLTHRT* from its combinatorial cluster for controlling open loop throttling MC.GTW_MODE=1, then the debug mode is enabled and the Intel 5000P Chipset MCH will use 2 windows for global activation logic to be valid. ...

... A mid level throttling level that is applied when the temperature is in the middle range (above Tlow but below Tmid) and THRTCTRL.THRMHUNT is set or the THRTSTS.GBLTHRT* bit is set by the Global Throttling Window logic in the Intel 5000P Chipset MCH. The maximum value this field can be initialized by software is 168 (decimal). This corresponds to 672 activations per activation window and gives 100% BW ...

... This field should be less than or equal to the THRTMID.THRTMIDLM. Description Reserved THRMODE: Thermal Throttle Mode 0: THRTSTS.THRMTHRT register is initialized by the Intel 5000P Chipset MCH such that they vary in range between THRTMID and THRTHI above Tmid (staircase) 1: THRTSTS.THRMTHRT register field is “slammed” to THRTHI above Tmid. THRMHUNT: Intelligent Thermal Throttle Enable 0: THRTSTS ...

The MC assumes that the Intel 5000P Chipset MCH is operating normally, that is not operating with only one FB-DIMM channel as in single channel mode this mode, the Intel 5000P Chipset MCH MC will operate such that only 1 channel (that is, branch 0, channel 0) is active and there can be one or more DIMMS present in Channel 0 ...
