Question GTX 1070, Gpu Usage and Gpu Power throttling

[Giuseppetm]

Hi, I've always had mini-freeze problems that I've always tried to ignore, but now I'm playing Metro Exodus and freezes are more visible than usual .. I think it's a problem related to the throttling of GPU use and power. My system:
ASUS STRIX GTX 1070,
Ryzen 5 1600 Stock,
Corsair Vengeance LPX 3200MHz (xmp is set on 2933MHz),
AORUS AX370 K5,
Antec 550W 80 + Gold.

I have no problems with temperature, the system is perfectly cool and stable, but I read some discussions that said the problem could be the power supply (since it can't give enough power to the graphics card).

I uninstalled Geforce Experience and my BitDefender antivirus, and noticed some improvements, but there are still micro-freezes that shouldn't happen.

Before unistalling gf experience and bitdefender:

After unistalling gf experience and bitdefender:

As you can see, the GPU usage and GPU power drop many times, causing FPS drops and freezes to the game.
I tried to clean unistall and reinstall video drivers with DDU and many other things.. please help me, i don't know what else to try.

UPDATE: Looks like even Cpu Clock has drops. https://ibb.co/wS2hJJr

The power supply should be fine.

Looks like your GPU is getting too hot and throttling (causing the drops in performance).

I thinked that too, but the gpu is very cool, about 50c fully stressed.

I misread the chart. GPU utilization is maxed and then drops. The drops coincide with the dips you indicated.

Do you have any additional applications running in the background? Has this rig been scanned for malware recently?

What power management profile are you using in Windows? Do you have the AMD chipset drivers installed?

Ok guys, i think i found the problem.

AMD processors have a feature called CoolNQuiet that lowers the clock when the computer is at rest. For some reasons, it does not understand that I am playing and lowers the clock, causing a lowering of the use of the gpu, and therefore of the mini-freezes.
By disabling the option from the bios, the cpu is now stable at 3.4GHz, allowing me to play properly.

I hope this will help someone.
