Thread: Tuning a graphics card's BIOS

Intel Core 2 Duo E6700, Asus Striker (Nvidia nForce 680il. 2 GByte RAM, Nvidia GeForce 8800 GTS 3DMARK06: 9.836 points (earlier 8.760 points) Motherboards are not the only devices with BIOS chips. Even graphics cards have a BIOS on which all GPU settings are saved. But you cannot access the BIOS of a graphics card using a shortcut or plugging in a jumper. You require special programs to access them: For Nvidia graphics cards, there's now a tool called NiBiTor, currently at version 3.7.
Using this program, you can not only read and change your own graphics card BIOS, but also swap it completely-BIOS variants tuned for many GPUs are available for download in the MVKTech.net forums.

Be careful in case of extremely high settings. This is a very risky process.
You can read the settings of your own BIOS from 'Tools I Read BIOS'. You should export However, you have to be very careful when making any changes-you could easily end up selecting clock or voltage values that can damage the card.



You can achieve up to ten percent better performance if you increase the parameters carefully: Our 8800 GTS ran stably even with a core clock rate of 570 MHz instead of 515 MHz. To permanently apply the new BIOS profile, boot up with a floppy disk and use the tool 'Nvflash.exe' to load your new BIOS profile. From now on, the PC will always boot with the new clock rates and you will permanently have ten percent more performance in games and 3D applications.

To reverse the process, simply use the same process to load the BIOS profile you exported before you began your overclocking adventure.
