R9 280 non-x BIOS request

Hello. I noticed it appeared new 280 bios techpowerup so i wanted to play around with one 7950 i had here. After flash everything was fine Vbe7 modded ofc for id change (it changed to 200 series) but voltage seems bugged. It's stuck at 0.999 so every game or benchmark crash right away with display stop responding. VRM is unknown, maybe voltage controller is not supported?

This is bios i was talking about : http://www.techpowerup.com/vgabios/156307/sapphire-r9280x-3072-140220.html

If anyone have any idea or some other 280 bios it would be appreciated. Thanks
