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

[idata]

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 https://youtu.be/QFSR7KUMk-E YouTube

here another video, geekbench with prochot disabled:

Hello chriz74x,

In regard to your concern with the temperature of your processor, it seems that according to the video references, it proves that the cooling system for your Asus laptop it is working fine. Due that never goes beyond to the temperature that it is expected.The temperature expected of your Intel® Core™ i7-3630QM Processor it is 105 C. you can confirm this details on the following link:http://ark.intel.com/products/71459/Intel-Core-i7-3630QM-Processor-6M-Cache-up-to-3_40-GHz?q=i7-3630qm# @specifications http://ark.intel.com/products/71459/Intel-Core-i7-3630QM-Processor-6M-Cache-up-to-3_40-GHz?q=i7-3630qm# @specificationsRegards,Angie

Actually the videos prove that the Asus is sending a BD PROCHOT signal to the CPU a little over 70°C which is far lower than what the CPU can go before throttling (PROCHOT)... The problem is this laptop doesn't have an option in the BIOS to disable bi directional prochot.
