i7-3630qm throttles to 1200 Mhz at less then 70°C if Turbo Boost is enabled
in General Notebook Discussions

I have an Asus laptop with hm76 Ivy Bridge chipset with Intel i7-3630qm, the CPU is 2.4Ghz and can Boost up to 3.4Ghz.
What happens is the CPU throttles to x12 (1.2Ghz) when Turbo Boost is enabled, this at less than 70°C, the TCC activation temperature should be 95°C!
The bios has the latest microcode patch v. 1C from Intel and before had the v. 15.
I made a test with cinebench and monitored the behavior of the cpu with Intel Power Gadget, ThrottleStop and SpeedFan, I made a video.
As you can see what happens is if I disable Turbo Boost with ThrottleStop the multiplier goes straight to x24 and the temperature goes up yet no PROCHOT signal is sent.
If I disable BD BROCHOT the temperature goes up but never arrives to 95° .. it arrives to 80° / 81° C.
So what is going on with this CPU??
I am now uploading the video to youtube and it will appear here
And here another test: GeekBench with prochot disabled:
and here enabled:
