Hi guys I have the Sapphire R9 285 Dual X. The thing is after overclocking and increasing the power limit by 20% it still throttles and I still have a lot of voltage to play with so I wanted to increase the power limit to 50% which I have done for other R series cards via VBE7. However, since this is a Tonga GPU VBE7 doesn't support the bios file. So is there any software out there for editing the bios of the R9 285?

I do have a dual bios. RBE doesn't support it. I don't mind flashing it to any bios or even bricking the GPU since un-bricking it would be easy as I have a motherboard with on board graphics.
So far at 1100Mhz with stock voltage here is my 3D Mark 11 Score-

The bios hack seems to have worked. The power limit is now at 50% and throttling has stopped. Thanks you so much smile.gif

The R9 285 isn't that bad of a card. It actually has a lot of potential but is held back by its bios.

Glad to hear it worked. Thanks for sharing.

There isnt much info on OCing the R9 285. This is the first time Ive seen the power limit increased. The core voltage can be increased beyond 100mv with special settings using MSI afterburner. Ive seen two people using about 130mv to get 1200 on the core. Seen one push beyond 1600 with LN2 cooling! His firestrike score was 10k! That is more than a stock 290.

I havent seen any 380 bios being shared.. could be interesting.

I have a powercolor r9 285 that I will play around with soon. Ill share my results when I am finished.

Good luck pushing yours.
