Make backup of original bios on video card. Using modded bios will void your warranty. I accept no responsibility for damage from using this information. All efforts are being made to double check information but there maybe errors.

Mind sharing the hex values and addresses? Since you are bored waiting afterall.

I'very manages to mod a 380x 4gb rom to work on a R9 285 along with using straps taken from a 290 rom. I got the best performance using a 1250 290 strap despite it clocking lower, but I'm willing to try others.

Also I will say I've flashed my 285 bad ... wouldn't boot... about 15 times and always have been able to fix with a 2nd gpu. Morality aside, I know I could flash back to stock and RMA without a problem.

8GB version, ram speed is 2000mhz as stock but the latencies are from the 1750mhz strap, so (if stable/working) you have more bandwidth/performance. If you post your 4Gb bios i can mod it.

2000Mhz strap is in the A6AA - A6DD block / Lenght 34 (40 0D 03 inverted = 2000)

ATIFlash can't find the card (no support yet, i guess).
Any possibility to flash this BIOS otherwise?
