How you unlock the shaders to 1024 with a Gigabyte ? I see for other brand but not Gigabyte.

Man, sorry for the late response. I got it from the der8auer article, some guy on the comments edited the bios to unlock it. So I modded it to allow more power and started to play with.

Actually, some bios of another brands will work too, but you will have to compare it carefully, to pick the closest to your vga. I was able to use a bios from PowerColor and another from Sapphire, but I dont remember the right models
