I have gaming x rx 570 4gb with samsung memory! I accidentally broken the bios and didn't have the backup. The bios available on techpowerup doesn't work on Samsung memory cards. I managed to find several unverified bios that includes Samsung memory, the card now post but gives error 43 after driver installation! I have tried pixel patchers, different drivers different bios.. contacted msi (they don't provide vbios). I just got this from.used market and don't know what to do. Would anyone help me out with the problem. S/N: 602-V341-203SB
