How to detect/observe CPU power (thermal) throttle? (reprise
Posted: Fri Aug 10, 2012 4:29 am
Maybe the first time I've posted my question in the wrong section: maybe I'll get a better luck asking here. Maybe.
Well, are AMD (as well as Intel, of course) CPUs supposed to scale down their cores' clock frequency/multipliers, when any overheating occurs?
In case, is there any setting, method, technique, or software able to show those throttling occurrences in any case?
The question may look rather obvious, but seemingly I'm not able to actually detect any change in cores clock frequency (I've used AMD OverDrive 4.2.1, CPU-Z 1.57, RMClock 2.3.5 and Throttle Watch 2.02), expectedly due to thermal throttle (currently on three AMD 10h CPUs, Phenom II X4 980, Athlon II X4 605e, Athlon II X3 420e), up to 117° C reported core temps (I used two more tools, Core Temp and SpeedFan).
I was also unable to detect any sudden deep dip in the temperature graphs (on SpeedFan), which would have been able to reveal a drop in clock frequency, as some one has suggested to me.
