290X voltage dropping below negative numbers since 17.4.3/Aggressive low voltages on 144Hz due to Wattman?

It's been awhile since I've been facing this issue, ever since the update 17.4.3, I had power states so low that it actually caused BSOD of Thread Stuck In Device Driver which has been solved as it seems, but there is still the issue of poor performance that arise randomly in game causing unbearable stutters which can be observed in HWinfo64, you can see voltages going below what would be called "normal".


I have absolutely no idea why this is happening by default and really, it shouldn't be. I do not feel like tweaking my BIOS to begin with so it would be nice to know what it is really going on and possibly be fixed.
