Here are the original and modded BIOS roms based on the instructions. Both are for my set of GIGABYTE Aorus Radeon RX580 XTR 8G. However, no matter what I have tried, Windows 7 hangs as soon as the "Your VBIOS has been imported successfully" message and I have to hard reboot. Cards were definitely updated because as soon as I boot into EthOS, I get dready super high speed fans....and 17MH/S. Begging for help because these cards are just collecting dust instead of mining.

Thank you so much!

Memory is Samsung? It should be cause vendor is 0x21, but you better check it!
I've insert Uber-Mix 3.1 to 2000Mhz so you need 2000 and more to be running. Check for mem errors.
I don't have RX 5xx or even Gigabyte cards, so I can't really tell what you need more, TDP and clocks are set very high for stock... so I didn't change it, should be fine.
BTW did you use GPU-Z for backup? RX 4xx bios have 256KB, but yours have 512KB? I think it's not right. Use ATI flash for backup.

Matthew, wow thank you so much buddy!!!! Let me try this now and report back.

Yep, but first please check if bios saved with ATI flash has 256 or 512KB!
