Ok, so I just got a used, yes I know, Sapphire Nitro+ RX 580, got a good deal on it and I think I know why. I think it must have been in a mining rig, should've seen that one coming, cuz the core clock is only at 1320 when it's supposed to be at 1411... No big deal, right? Just overclock it! Yeah, can't do that either, not in Wattman or Afterburner. I select Auto Overclocking and it gives me "0mz" and when I overclock manually and click "Apply" it just resets back to 1320... I have the BIOS switch on the performance setting as well... I have a feeling, but not entirely sure, the solution is to flash the BIOS, yet I have no idea how to do that... Any ideas?
