CPU throttling issue

[Camaro7]

Hey there,

 

I've been having an issue with my laptop recently. The laptop is a Lenovo Z50-75 with an FX7500 (2,1 base clock), 16 gigs of ram, and an R7 M260DX card running Windows 10 64 bits. The laptop is not even a year old, it was running great so far, but recently the cpu is misbehaving. I use AMD Overdrive since i have it, and i had no problems. Even without the overdrive the max speed was 3.3 GHz. And everything is fine, right until I launch a game. The moment a game starts, the multiplier goes back down to x11. That's 1.1GHz. long as the game runs, the clock speed won't go above it, but the moment I close the game, it immediately jumps right back to x25,x28,x33(automatic). I tried with Armored Warfare, The Crew, and I have even tried an old game, Serious Sam: The Second Encounter just to see what happens, and it's the same. CPU Throttling immediately. I even have a cooler pad under the laptop running all 5 fans, the laptop is blowing out a cold blizzard, so there's no overheating issue here(not that there could be, considering the 1.1GHz). I have tried everything that comes to mind. I have every driver installed, the latest 17.9.2 amd driver, everything set to performance mode, in the energy management driver as well, and in windows as well(power plan is set to high performance). Even the advanced power plan settings are all set to the max, minimum clock speed and everything related are set to 100%. Does anyone know how to stop this ? Games that were playing great are now struggling on low settings... I tried old amd drivers, without overdrive, I even got an older version of win10, tried on win 8.1, but it's the same. 

 

Thanks in advance,

Norbert

 

P.S.: Of course the laptop is plugged in.
