Well for starters your card is 580 but seems its been flashed with a 570 bios. Get the right buos on the card to start with.
Does it have a small switch to a second bios? If so see if the original is still there in second position.
yes it has 2nd bios switch too. i slide that switch to hdmi side & it's RX 580 there too. but the strange thing is why furmark show it as RX 570 on detected GPU while GPU-z show it as RX 580.
I have tried with 1750 mem clock too but never works
