Much like computer motherboards, video cards have a BIOS (Basic Input Output System) which controls aspects such as the graphics chip, chip clock and memory clock. You can make changes to the BIOS of your nVidia GeForce XFX, such as increasing clock speed, using a select group of programs. Updating the BIOS for your video card is a complex and time consuming task that's not without risk. Only update the GeForce BIOS if you are certain it is necessary.
Instructions
1. Open your browser and download GPU-Z, NiBiTor and nVFlash. Save the files to your desktop.
2. Launch GPU-Z by double-clicking the "GPU-Z.0.3.8.exe" file. Click the "Graphics Card" tab and locate the "BIOS Version" section.
3. Click the icon to the right of the "BIOS Version" section and click "Save to file." Save the file to your desktop and name it "OriginalXFX." The file will save as a .bin file.
4. Launch NiBiTor by double-clicking the "NiBiTor.v5.0.exe" file. Click "File" at the top of the window then select "Open BIOS." Navigate to the "OriginalXFX.bin" file that you saved with GPU-Z and click "Open."
5. Click "File" then select "Save BIOS." Click "Save As" and select "Save as Nvidia (.rom)." Name the file "OriginalXFX.rom" and click "Save." This is a backup of the original BIOS.
6. Change settings to the clock, boot docks, voltage and fan speeds of your video card by clicking on the tabs in the lower portion of the window and entering the desired values. Ensure the "Integrity" section has a green circle next to it in the upper right corner of the window. Click "File" then select "Save BIOS." Click "Save As" and select "Save as Nvidia (.rom)." Name the file "UpdatedXFX.rom" and click "Save." This is the updated video card BIOS.
7. Insert a blank floppy disk into your floppy disk drive.
8. Click "Start" and select "Computer." Right-click the "A:\" drive and select "Format."
9. Select "FAT32" as the file-type and place a check-mark next to "Quick Format" and "Create a DOS startup disk." Click "Start" and click "OK" when the system warning appears. Allow the computer to create a start-up floppy disk.
10. Open the contents of the floppy drive by double-clicking the "A:\" disk. Right-click the "autoexec.bat" file and select "Edit." A notepad document will appear with existing text.
11. Add "nvflash - 4 -5 -6 UpdatedXFX.rom" to the very bottom of the document. Click "File" and click "Save." Exit the notepad document.
12. Unzip the nVFlash file folder. Copy the containing "nVFlash.exe" and "CWsdpmi.exe" files from the nVFlash folder to the bootable floppy disk that you just created.
13. Copy the "OriginalXFX.rom" file that you created in Step 5 and the "UpdatedXFX.rom" file that you created in Step 6 to the floppy disk.
14. Restart your computer and boot from the floppy disk. A command prompt window will appear. Note that you may need to change the boot order in your motherboard BIOS to boot from a floppy disk.
15. Input "nvflash" into the command prompt and press "Enter." Input "nvflash --index=1 -5 -6 UpdatedXFX.rom" and press "Enter." Do not interrupt the procedure as the program flashes the BIOS of your graphics card.
16. Reboot your computer and remove the floppy disk, once the process has finished.
17.Reinstall the drivers from your video card by either inserting the driver installation CD that came with the graphics card or by downloading the drivers from the nVidia website.
