THRTLOWLM: Thermal Throttle Low Limit
A base throttling level that is applied when the temperature is in the low range
(below Tlow) and THRTCTRL.THRMHUNT is set and the THRTSTS.GBLTHRT* bit is
not set by the Global Throttling Window logic.
Note:
This base throttling is also enabled If THRTCTRL.THRMHUNT = 0 and
THRTSTS.GBLTHRT* bit =0.
The maximum value this field can be initialized by software is 168 (decimal). This
corresponds to 672 activations per activation (throttling) window and gives 100%
BW.
The granularity of this field is 4 activations.
0: No throttling (unlimited activation)
1: 4 activations per activation window
2: 8 activations per activation window
168: 672 activations per activation window
If Software sets this value greater than 168, the chipset will cap the THRTLOWLM
field to 168.
THRTMIDLM: Thermal Throttle Middle Limit
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.
The granularity of this field is 4 activations.
0: No throttling (unlimited activation)
1: 4 activations per activation window
2: 8 activations per activation window
168: 672 activations per activation window
If Software sets this value greater than 168, the chipset will cap the THRTMIDLM
field to 168. This field should be less than or equal to the THRTLOW.THRTLOWLM.
Intel® 5000P/5000V/5000Z Chipset Memory Controller Hub (MCH) Datasheet
The GBLTHRT* is an internal signal from the Intel 5000P Chipset MCH open
loop combinatorial cluster before it is latched in the THRSTS.GLTHRT
register. This will prevent any stale/delayed information from being used
for the open loop throttling logic.
