I like to think I'm fairly seasoned when it comes to GPUs and their bios's. But this baffles me!
I bought a hand full of Gigabyte and MSI RX 560 4GB. I bought them knowing they were likely mined with. Once I got them home and checked out GPU-Z, I was fairly certain they were previous miners and their BIOS was likely flashed and/or altered. For me, it's when no benchmarks (furmark or heaven) work and the GPU Clock and memory is "0" in GPU-Z. So I hunted down the appropriate Bios through TechPowerUp, trying to find official bios's as best as I could and ensuring the GPU/Memory clocks were factory settings while also matching the memory manufacturer. I flashed them all using ATIFlash, rebooted and they worked fine! I was able to confirm within GPU-Z and they ran all benchmarks beautifully!
I put the cards off to the side for a couple weeks. I decide to install one into a new PC.... Nothing. No image, no notta. So I try all of the other cards, in multiple different PCs. And all but one had the same outcome. Baffled! Fortunately I saved each bios that was on the card previously and quickly flashed them back to their original state as I bought them. I did this with a secondary Nvidia card. Most of the cards were now able to show a low resolution image. However, as for the one card that did work... it worked on two of my three PCs. I've eliminated all possible other hardware issues... It's got to be a problem with the bios. I even thought maybe there's a possibility that the make of the VRAM that's stated in GPU-Z may be based on the BIOS that's loaded. So I took the card apart and confirmed the physical make of the VRAM chip.. everything is correct.
At this point, it feels like each card has a mind of their own. The one card that was working well, with the correct BIOS, worked in a couple PCs a couple of times with being able to benchmark and run good resolutions... But now, it some how reverted back to "0" on the clock and memory and unable to run benchmarks. I have no idea how!
What am I missing? Help?!
