GPU stuttering like crazy

[Mr.Hans.-]

So in any game even in msi kombustor my gpu goes from 350watts and 300 fps to 20 fps and 30-40watts and goes back up and it happens every 15 seconds i've tried a lots of things already and it didn't work including windows reset

no, i dont have any other i have be quiet system base 9 600w

[bmx6454]

do you have a voltmeter to check yours? or another pc to try your gpu in?

 

edit: on most mobos, you can use your bios to monitor voltage, and watch for a 15s fluctuation, but i prefer voltmeter to test under load.

Maybe because of the vega 64 bios? I didnt know you can just do that.

But you can also try setting your power limit to the max and lowering the clock a bit

No it's very unlikely a bios problem 

It sounds like a power delivery problem

i can confirm it was a bios problem
