[G46vw] Unlocked Bios?

I'm looking to see what performance increases that can be had with some further OC'ing and TIM repasting (the 660m struggles on a FHD screen). I'm not looking for great jumps, just something that would help this machine to handle FFXIV at FHD.

BUT . . .
I can't seem to find a G46vw unlocked bios floating around anywhere . Could anyone point me in the right direction to where I could obtain one?
