Values are GREAT!
Margin, as in amount remaining to event.
-40 = 40 deg C below therm trip.
Ok so how do I calculate realtime value now ?
therm_trip + P1_Therm_Margin = realtime_temp
Where do I get this therm_trip value ?
As per the Thermal and Mechanical Design Guide:
The TCC activation temperature is calibrated on a part-by-part basis... TCC activation temperature may change based on processor stepping, frequency or manufacturing efficiencies.
This means there is no defined TCC for certain model. However, you don't really need to warry about the actual temperature - just keep the Therm_Margin below zero, and the processor should work well.
