Do you have a reference design 7990? It is actually possible and I have come across quite some UEFI GOP enabled HD7990 BIOSes, you can find my VBIOS collection here: https://drive.google.com/file/d/0B29z6-xPIPLEQlZHcWVacURIRWs/edit?usp=sharing
Just look them through - if you have any software, which can batch search for strings inside these files, you can find the right VBIOS very fast. I currently have no time to search it for you, but I have time next week. If you are patient enough, I can do this for you
For reference HD7970 users, without VRM temperature sensors:
This is a UEFI GOP enabled R9-280X BIOS, which runs very well and stable on my reference HD7970 card. Give it a try, if you were out of luck until now.Edited by tolga9009 - 3/10/14 at 2:00pm
