This modified VBIOS didn't allow me to up my overclock at all. I had no problems flashing to the modified BIOS. I used both Winflash and the bootable USB stick method just to be sure. For those wanting to use Winflash and are having problems with the error message saying their current BIOS is newer you can just launch Winflash from command prompt with an /nodate modifier. Open command prompt and find the directory for Winflash then to launch the .exe type "Winflash /nodate" (remove the quotation marks). You'll still get the 'newer version' error message but it will let you flash the modified BIOS anyways. I hope you have better luck with this BIOS than I did because for me it didn't let me overclock any higher. The best stable overclock I can get is 780 CPU clock with a 970 memory clock with either the ASUS BIOS or with this modified one. I can't be certain that it upped the GPU voltage since GPU-Z reports 0.9000 volts with the stock VBIOS and this modified one so I suspect the app can't properly read the GPU voltage for the 555m. The limiting factor seems to be temperatures. Once I hit 77-78 degrees GPU I get freeze up no matter what the clock. What we really need is the ability to control the fan speed. Has anyone found a way to do that? Also, be sure to uninstall Power4Gear hybrid. That's ASUS power management software. Once I got rid of it and just used the power options built into Windows I noticed a large drop in my temps. You can further control temps by disabling Turbo boost of the CPU. Go into power options in Windows, be sure you're in high performance profile, and select 99% for minimum processor speed and 99% for maximum processor speed. The CPU will stay out of Turbo boost as long as it never reaches 100%. You don't need CPU Turbo boost for games since mostly it is the GPU that is limiting not the CPU. Good luck and let me know if you find a way to control fan speed. Also, if someone wanted to take apart their N55SF and test it with a volt meter I think that would be the only way to see if this modified BIOS actually changes the GPU voltage to 0.9250. I certainly doesn't seem that way since it didn't allow any higher overclock for me. Thanks for the effort for those that created the file though. It was fun to play around with.
