Hello,

I bought 4 R9 280 for mining, and I want to flash a mining bios into it, there's a lot of optimized mining bios for a lot of GPUs but I can't find any for this one !
And I'm too afraid to modify it by myself, except if you have a good link with a good step-to-step to modify the bios for this gpu, this it what it looks like :



I also have one Asus HD7970 Matrix Platinum.

Thank you all!
