I have a Sapphire NITRO+ RX 580 8G GPU and for some reason it wouldn't go over 1250 mhz even though it supposed to go up to 1411 mhz boost clock. I tried to overclock it but every time I set a clock speed and apply it, it instantly reverts back to 1250 mhz. I tried it in Adrenalin and MSI afterburner. What am I supposed to do? How can I overclock it?
