winflash says the original is bios is older and does't let me flash back, and insydeflash doesn't seem to work with asus. After research I have found the problem, the new nvidia drivers do not allow the graphic card to go over 80c, so with this volt mod, it has effectively reduced my max oc from 780 to 725 due to the extra heat from voltage, during games after a various amount of time I get a blue screen when my gpu hits 80c, this does not happen with the old nvidia 168 drivers as there is a higher heat limit allowed, but the drivers aren't as optimised so they aren't worth keeping even though I can overclock higher with them. Also before the voltmod my temps would never reach 80, so I could reach the gpu's max of 780 withoout blue screen, pretty annoying, is it possible you can "modify" the original bios file for me and upload it so I can revert back to it as it would allow me to keep my overclock at 780 with the new drivers, instead of the current 725 due to overheat reaching 80 = blue screen :S
