    How to use nvflash

    This may be a dumb subject, however since I have never used this program before I would rather make sure I am doing it right rather then brick the card. So I have a GTX 465 (doesn't have the right amount of chips to unlock to 470) and I would like to raise the cap on the voltages. I have already modded the bios and am ready to flash it. I pull up nvflash for windows and I get intimidated because I don't know any of the command lines. So if someone could provide a step by step for using the program in windows I would be eternally thankful. Thank you

    Here's what I do:

    0) Be very, very, very sure you have the right bios, and only one GPU in the system.
    1) Put the new bios file in the same directory as nvflash. (I like c:/nvflash, easy to get to)
    2) Fire up the command line, get to the nvflash directory.
    3) Type "nvflash -4 -5 -6 biosfilename.rom", no quotes.
    4) Hit enter.
    5) If it gives you nonsense about a protected bios, type nvflash /? and find the flag for unlocking the bios, use it, then go to #3.
    6) Party!

    Everytime I try to type in the command line it changes to a different set of instructions i.e. I it n and it goes somewhere I hit v it goes somewhere etc etc until it closes itself out. Basically it's not letting enter the command line. Basically I start the exe and the windows comes up but I can't put anything into aside from a single letter. What am I doing wrong?

    Alright, I might be a little daft, but I cannot for the life of me open nvflash in command line. Everything I read is not helping me. If someone could give me a step by step instructions to opening up nvflash in the CLI I would be eternally thankful. All of the guides I see online are to use a flash drive or something similar. Now I am under the impression that the version of nvflash that I have can used in windows.? Is this so? Thanks

    Try this one.

    You basically, just open a cmd prompt, change the directory to where your nvflash files and BIOS are located, then type "nvflash bios.rom -5 -6" where “bios” is your BIOS name.

    Thank you for the reply good sir, however I have one more probably incredibly stupid question: if nvflash is in a folder on the desktop, how do I change the directory to get to it. i.e. what is the exactly command line to do so. (like I said probably a dumb question.... I am just unfamiliar with command lines)

    cd <directory>

    That's the command, just put in the directory to your file for <directory> like so "cd desktop\folder"

    I keep getting 'nvflash' is not recognized as an internal or external command, operable program or batch file

    Sounds like you're still not in the right directory. Is there a folder in the folder or something?

    ok my directory right now reads C:\users\bench\desktop\nvflash> I just tried the command line from the guide but I get the same error as above. Also I just pulled everything from the folder and placed it directly on the dektop along with the bios etc etc
    Edit: I placed everything on the desktop before i got the command directory to work

    I got it sorry for being so daft, but I sincerely appreciate the help
    edit: new voltage tops out at 1212 so it was a go! Now that I have done the command prompt thing I will not forget Thanks again

    Glad you got it figured out. Putting everything on the desktop would have been my next suggestion...lol.
