GTX 400 Overclocking/Modding Thread - Page 82

post #811 of 926
Hey everyone, I wanted to let you guys know of an easy way to flash your bios using nvflash, Nibitor, and windows command prompt. Works for any card supported by nvflash an nibitor. First off make a folder in C:\nvflash and extract all files that comes with nvflash into it. Then load up windows command prompt;
use the command CD\nvflash
then C:\nvflash>nvflash -b (file name what ever you want).rom ex. C:\nvflash -b ASUS.rom, this will make a backup of your current bios.
Now fire up nibitor and open that Bios file up, edit it to what you want and save it to a different file name in C:\nvflash, Ex. ASUSOV.rom. You can manually change file name to .rom if it saves as .bin.
Now open command prompt again use the same command CD\nvflash followed by the command --protectoff, C:\nvflash>nvflash --protectoff: this will allow you to rewrite the bios.
Now you can use the edited bios file to flash, with the command nvflash (bios name here) ex, C:\nvflash>nvflash ASUSOV.rom, confirm the flash with Y.
After that completes follow it with the command --protecton, C:\nvflash>nvflash --protecton.
Restart and your good to go.

Ive always been warned against bios flashing from windows.... On a few motherboards I have had no other choice, but always on gpu's I have used a bootable..

Making a bootable USB is fairly easy as well...

I will also NEVER flash a GPU unless I have a spare to fix a bad flash...


Once I get my VF3000 I will flash mine to allow more voltage... At least for some good bench runs if nothing else..

Right now I hit mid to high 70's in game at 90% fan... Stock cooling sucks...

I wouldn't worry about flashing your bios till you have aftermarket coooling for the card.. As that is the only reason we really flash, is for more voltage.
Something that should not really be done on those reference coolers.

Im getting a gtx 460 in the next couple of days, i'll be using the swiftech mcw60/g80 to water cool it. My question is since i am interested in the asus directCU gtx 460, i read somewhere that it has been made possbile to tweak voltages. Does this mean that if i go ahead and pick the asus that i will not need to flash the bios?

Btw is the asus 460 a good choice to water cool??

Thanks

I actually have an Asus 470 and yes it comes with software to tweak the voltage, with the limitation of 1.087 or something like that. All fermi cards to my knowledge are locked at a certain point, its just a factory safe setting and a warranty based thing. Flashing the bios is quite simple though if you just follow my instructions, and use your bios from your card. Do not try to flash it with a downloaded bios, this will add extra issues like incompatibility and so forth. Just use nvflash to strip your bios and edit it with nibitor.

i know how to flash a bios but im worried as to how this works. If something goes wrong is there a default bios that will be reset. As i have an asus board do i just download afterburner 1.6.0 final and the bios upgrade to over volt the card past 2? If i download the biod mod will it leave the rest of my bios alone? Will my settings be the same or will i need to re over clock?

Is this flashing the computers bios or only the bios for the gtx 480 only? To flash that do i only need nvFlash the asus .rom for the 480 over volt?

Also if i want to revert back to the original i can just do this with the asus stock .rom?

If you are that unsure about what you are doing, you should probably do more research. Not to be unhelpful, but you really need to know more in case something does go wrong. This can brick your card and cost you your warranty if done wrong.

Flashing the BIOS is cake. I did it like five times (no exaggeration) yesterday. You can use 1.6x Beta 6, 2.1 Beta 4 unlocked, or any version if you happen to have the voltage unlock tool.

This will just flash the BIOS to the 480. If you mess up, use your other card for display and reflash it.

This is the process (assuming you have your bootable flash drive set up with nvflash on it):

nvflash --eraseeeprom
nvflash --list
(note which number it is)
nvflash --index=(number) -4 -5 -6 biosname.rom

Typed that from memory lol. You get good at it when you've done it as much as I have.

What card? I think the only bios mod for OCP is the 480, and I am not sure thats even the case..
I know that the 470 & below require a hard mod.
Here is the info for the 480 mods - http://www.xtremesystems.org/forums/showthread.php?t=251935
