Question What is happening with my GPU? (Radeon rx480)

[Walter825]

Hello, I recently find that my GPU is having problems, when I try to run a game it appears a massive stuttering every second, and apparently the GPU load does not rise of 0%, something seems to be wrong with power load voltage and the core clock they are unstable, i dont know what is causing this.
About 2 months ago everything was working fine, I already had this issue like 1 year ago, but i format my pc and I dont remember what else I did but it seemed that it had been fixed.

I do not know much about these technical issues, but I always thought it was a problem with the power supply and voltage fluctuation

I hope you give me your opinion and advice of what I can do or try, i also try to install older drivers but the problem persist, so i think i a hardware problem

Here is my PC components:
RX 480 msi gaming x 4gb
core i5 6600
16gb ram

Board MSI B150 gaming m3
Power supply EVGA 600w bronze
SSD 120gb
2 HHD 1tb
I have windows 10 pro (1803 version) and AMD driver 19.3.1

I will leave some videos that I uploaded so you can see exactly what is happening:

Here you can see how show 100% GPU load in GPU-Z App but 0% in MSI Afterburner app, i dont know what is happening

Is the display cable plugged into the GPU or one of the display outputs on the mobo rear IO cluster?

is pluggen into gpu with hdmi

I set the power limit to -50 wich is de minimun and the difference is actually huge, watch the videos, so maybe is a PSU problem?

I have the MSI RX480 Gaming X 8GB, so aside from the fact that my VRAM is 2000MHz and yours is 1750MHz, we have the same card.

Are you familiar with AMD WattMan? It's included in the AMD driver software. Does everything Afterburner does.

Here are my manual voltage settings at each frequency State:
610MHz/818mV
910MHz/865mV
1075MHz/900mV
1145MHz/920mV
1190MHz/935mV
1235MHz/950mV
1305MHz/1020mV

VRAM = 910mV

In FurMark, GPUz says my GPU power draw is 100W @ 1305MHz.

On my personal machine, WattMan doesn't apply the manual voltages correctly on cold boot. I have to restart, then everything is applied fine. I have about a 50% success rate with that in other machines I've worked on.
