Hi, guys! I have a Sapphire HD 7850, I want to unlock its voltage so I can push it to 1.3v 
I tried RBE but it seems that it can't recognize my bios saying it's not an ATI BIOS, I also tried Radeon HD 7000 BIOS Editor but it says voltage control is impossible as my card is non reference.
I heard that asus dcii top bios unlocks voltage so I flashed it but it broke my card! 

So is there anyway to modify my Sapphire bios? This is my current bios:https://www.techpowerup.com/vgabios/138866/sapphire-hd7850-1024-130124-2

 

If anyone can modify it for me I will be grateful!

Flashing BIOSes from other cards is never a good idea. Have you tried MSI after burner? I had my old HD 7870 on 1.3v and it worked fine. 

Yours faithfully

Yea ASUS DCII BIOS broke my card but I reflashed it with the original one and it's working fine now. And yes I've tried MSI AB but I can't exceed 1.225v I also tried sapphire trixx and asus tweak with no luck!

Did you unlock the voltage control to third party? If not then there isn't much you can do for "software" voltage control I'm afraid. 

 

Yours faithfully
