So I bought a used miner rx 580. It’s a XFX XXX 580 4gb. The card has a bios switch with 2 positions - left and right. The right one didn’t give a video signal at all, so I used the left one. With it the display constantly flickered and games couldn’t run. Furmark worked fine(the version of the benchmark that doesn’t use vram) and the card got a good score. It also green screened a bit. So all this, in my mind, points to the vram being faulty. I cleaned and repasted it and I underclocked the vram severely and viola it(kind of) helped. It stopped the flickering. I tried running a couple of games and only one of them ran - AC Unity, it ran fine. So at this point I contacted the guy and told him the card was faulty. He agreed to replace it with another one from his rig but advised me to flash the bios to check if that’s the problem.
I downloaded the only bios in techpowerup for a xfx 580 4gb. It seemed all was ok until after the restart the gpu didn’t give any signal. And I flashed the left bios, the one that at least worked.
I don’t have an igpu but a friend does and I might try re-flashing the card on his pc. But my question is - is it worth it? Was I correct in my original assumption that the vram was bad? Should I just request a new card?
P.S: I used the 3.31 version of atiflash; The guy I bought it from also told me that this faulty behaviour of the card is to be expected if Im using it with his bios; I flashed the bios while using the rx 580, as my 5700x doesn’t have integrated graphics.
