R9 390X: Artifacts and crashing

[Margott247]

Hello, I recently got an R9 390X 8GB (The MSI Gaming variant) and found out it was artifacting and someone (reflown?) it. It has started artifacting again after 6 hours of use since i got it (no gaming or 3d, just after installing drivers)-

 

When i put the gpu in my other system and underclocked it by a significant amount, stuff was running normaly for a while, there were no artifact and the game/benchmark later crashed.
I would like to get this card to work, even if significantly underclocked. Is there any way to get it at least somewhat stable now?

I can provide more info, that you may need

Maybe check temperature of GPU while under load. GPU-Z for example would show it.

about 40-60, i also repasted the chip but left the thermal pads as they were

It could be potentially a power issue, does your power supply supply enough power for the GPU?

Yes its a 650w silentiumpc unit

Try letting the power drain completely, pull the GPU for a few minutes, then reseat it.

 

Failing that reinstalling windows is the quickest solution to software issues. Or just DDU and try and older driver I suppose.

If it only artifacts underload you may need to lower the voltages/speeds/or power target of the GPU.

Then your PSU is fine, either, so, either way, it's a driver issue. Or the GPU is dead, or dying. The reflow was most likely done to fix the card, since it was broken for some unknown reason.

Aw frick. That sucks to see such a still usable gpu die when ive got 210s lying around working, as well as a 7300GS...

reflowing a GPU does not fix it. A reflowed die that is a broken die is still a broken die. If this was sold as "refurbished" it's a sham.
