RX570 4GB Powercolor RedDevil Hashrate and HiveOS overclock settings 31 mh/s RX 570 crypto ETC ETH

I saw these massive on ebay and couldn't resist. I paid $70 per card. The shipping was rediculous but I was able to get all the card running and bios modded. I could push probably to 33 mh/s but I like stable systems. I'm running in these in HiveOS and getting around 75W-80W per card.

Thermal Paste I used to repaste cards
