Urgent, I need steps to reflash my BIOS.

post #1 of 2
Thread Starter 
I have no clue how to reflash, but I downloaded the .rom filed and it's called

"N660O2GD.f23" (it's not a .ROM file, will it work?)

if you want to give me step-by-step instructions.

Thanks in advance.

Furthermore, I am taking a risk on which BIOS to use; I deleted my original BIOS .rom file and can't determine if I have Samsung or HYNIX memory without removing the GPU's cooler. Sticky situation, but I'm willing to try it out (because I have to 660s).

Step 1: Download this Zip file nvflash.zip 342k .zip file and extract the "nvflash" folder to your desktop.

Step 2: Download and install GPU-Z V0.6.9, and save your ".rom" file to your desktop by clicking the the "save BIOS" button in GPU-Z. Warning: Spoiler! (Click to show)
Rename the saved BIOS file from "Gk106" or "Gk104" to "660.rom", and move it to the nvflash folder on your desktop. Warning: Spoiler! (Click to show)

Step 3: Run Cmd.exe (command prompt) and navigate to your Nvflash folder with this command line "cd desktop" [hit "Enter" on your keyboard]. "cd nvflash" [Hit "Enter" on your keyboard]. Then type "kgb.exe 660.rom unlock" [Hit Enter on your keyboard], and your BIOS should be unlocked. Your command prompt should look like the image below "IF" you did everything right. Warning: Spoiler! (Click to show)

Step 4: Close and re-open Cmd.exe (command prompt), and navigate to your Nvflash folder by using the command line. "cd desktop" [Hit Enter on your keyboard]. "cd Nvflash" [Hit Enter on your keyboard]. Then type "Nvflash -4 -5 -6 660.rom". At this stage, your command prompt screen should look like the image below Warning: Spoiler! (Click to show)
Hit Enter on your keyboard again, and another cmd window will open asking you if you want to continue flashing by pressing "Y" on your keyboard. Warning: Spoiler! (Click to show)
Press "Y" and it will proceed with flashing the card with the modded BIOS.

Step 5: To test if your card is running at 1.212mv, restart your computer, and download Nvidia Hair demo. Install and run it while running GPU-Z monitoring application in the background. If your Modding/Flash was successful and everything works fine. Your GPU should show up 1.212mv thumb.gifWarning: Spoiler! (Click to show)


NOTE: If you are having problems with GPU-Z and saving your BIOS, try to download your BIOS from your manufacturer's website, and take out ONLY the .ROM file, rename it to 660.rom, and move it to the nvflash folder for unlocking. Lucid Virtu Mvp software can also cause problems for you while trying to flash your BIOS. I will advice you uninstall that software as it plays no valuable/beneficial role to gaming. The latest Nvidia drivers are enough for any v-sync problems you might have in games.

Added information about not having my original BIOS. I would appreciate instructions on how to use the same program (that I used to mod my original BIOS) to reflash my BIOS.
