I'm having problems and I come here to ask for help you,

My card is very instabil , I do not have a multimeter to see which is the exact voltage, temperatures are relatively good, I'm with the XOC BIOS, I can now reach up to 880MHz in AtiTool without artifact, black screen when I have more road OCCT GPU and VPU recovery times in the games and many artifacts.

What should I do?

Remembering that I have very little experience in v-mods.


May be guilty of my Trimpot?

The Weld may be poorly enforced?
