Intel i7-6500u downclocking for termal throttling even at low temperature

GMine1 — Tue, 05 Sep 2017 15:49:10 GMT

I have the following problem and i noticed it only after Creators Update in Windows 10:

(My laptop is an ASUS K501UX with i7 6500u cpu and NVidia GTX950m gpu and Windows 10 64bit)

Whenever I try to play or make some heavy task, in performance mode and AC plugged-in, I have serious problems with dowclocking of cpu, making fps going down to 5-10 fps after a while, an issue that wasn't there a year ago, when I bought the laptop. For example, bf4 used to run smoothly and now is totally unplayable.

So when I run intel XTU to monitor the system during load i always see the Thermal Throttling bar fluctuating between the value "Yes" and "No" when the temperature reaches 49° C.

I've also used the Intel Diagnostic tool and the cpu passed every test.

I've tried to update (and then also to downgrade) the drivers but nothing happens, the problem is still there.

Is there a way to solve this problem?

Thanks

(as it can be seen in the picture, recent mean value of thermal throttling is "Yes", and after a while the Max Core Frequency get stuck on 0,4 GHz)

Hello Gabriele.mno,

Thank you for contacting the Intel community.

Please bear in mind that the Intel® XTU reads the information from your computer BIOS so this depends on your BIOS and how all the components interact with each other.

At this point, I strongly recommend contacting your computer manufacturer for better support, I would try to update the BIOS and run Windows® update to see if helps.

You should be able to get support here:

Thanks, after your hint i've found what seems like a solution:

opened the BIOS, then loaded "Optimized Defaults" (in my pc simply using f9).

That's it, no more unexpected/faulty thermal throttling even at really high temperature, the cpu even under a huge load doesn't underclock, the core frequency is always on 3,1 GHz as expected.

Thank you!
