Title says it all guys its for my own research purposes, and while I'm at it I'll also upload tweaked versions for people to try out.
nvflash update procedure
This is just a rough and quick explanation for people to reference to ensure they have a successful vBIOS flash.
Assuming you are going to flash from DOS (safest) and use a USB stick here is a step by step procedure to flashing your vBIOS.
- Download a USB boot utility and boot files
- Format your USB stick then run the USB boot utility to make your USB stick bootable, remembering where you downloaded the boot files to as you will need them
- Place nvflash and your modified vBIOS on to the USB stick
- Restart, selecting your USB stick either via BIOS or boot menu as the boot media
- After the USB stick loads the boot files type;
nvflash -j -4 -5 -6 filename.rom
Thats it. Ctrl>Alt>Del to restart, run something like GPU-Z to verify the new clock settings and/or voltages and you're done!
