Hello guys, i bought a used RX 570 Gigabyte 4G and im sure there is something wrong, like used for mining, as i cant install the drivers giving me error 43 from Windows, but when i use the ATIKMDAG patcher its fine, but after playing a Little with games it crashes MY PC: ASUS PRIME A320M-K Ryzen 5 1400 12GB RAM Windows 10 64 bit Pro
It may just be memory that requires a lower clock speed, that is, if it was used for mining.
Most likely, it has its own BIOS, due to which the driver will not be installed without running the pixel patcher every time the system is rebooted. You will need a stock BIOS and flash it. This is a rather complicated process and can sometimes "lock up" the GPU. Out of more than 30 times I have flashed the BIOS of an AMD GPU (for mining), only about 4 times it “locked”, but each time I was able to recover by forced flashing the BIOS using the Windows command line. Try to find the original bios here - https://www.techpowerup.com/vgabios/
I have flashed the RX 570 biography from the Gigabyte website and now the driver is installed without issue (no patcher), I test the game and let you know if it crashes
My game in the woods crashed (fastest game that crashes on my computer) after flashing BIOS and installing drivers, I no longer get error 43 but it crashes
I think i solved it, i underclocked it and now it doesnt crash, so basically the solution was to flash the bios from webpage manufacturer and underclock the GPU
