Easy NVFlash Guide with Pictures for GTX 970/980


Step 1:

Download the latest NVFlash from the following link: http://www.overclock.net/t/1521334/official-nvflash-with-certificate-checks-bypassed-for-gtx-970-980


Step 2:

Create a folder called nvflash on your C: drive or whatever your root drive letter is.




Step 3:

Extract the files from the nvflash zip file into the nvflash folder that you created.




Step 4:

Place your bios file into the nvflash folder.




Step 5:

Open the device manager by typing "device manager" into the start menu, and then click "Device Manager".




Step 6:

Disable your display driver by right clicking your display adapter in the device manager and clicking "Disable".




Step 7:

Open the Command Prompt as an administrator by typing "cmd" into the start menu and then right-clicking it and clicking "Run as administrator".




Step 8:

Navigate to the nvflash folder that you created by typing the following into the command prompt, and then press enter:
cd C:\nvflash




Step 9:

Type the following (for single GPU configurations) into the command prompt and then press enter (replace ROM_NAME with the name of your bios file):
nvflash -6 ROM_NAME.rom




If you have multiple dedicated GPU's installed, then type the following (First type nvflash --list to find your device index, and then change the index number to whatever card you want to flash to):
nvflash --index=0 -6 ROM_NAME.rom






Step 10:

NVFlash will ask if you want to continue two times. Type "y" both times. Wait for it to flash (If your flash fails in the middle of flashing DO NOT restart your computer. Keep trying to re-flash until you get a successful flash). When it is done, type the following into the command prompt and then press enter:
exit


Step 11:

Re-enable your display driver by right clicking your display adapter in the device manager and clicking "Enable".




Step 12:

Reboot your computer and that's it!

FLASH AT YOUR OWN RISK! I AM NOT RESPONSIBLE FOR ANY DAMAGES THAT MAY OCCUR WHILE ATTEMPTING THIS!

Also, follow my other guide for disabling boost and "baking-in" your max game stable OC if you want. It has helpful info for increasing your power limit (See Step 6): http://www.overclock.net/t/1522651/disable-boost-and-bake-in-max-game-stable-clocks-for-maxwell-ii

Having a bit of an issue at the cmd portion.


When I type nvflash --list, it says there are no nvidia display adapters.


I extracted the nvflash.zip to my desktop --> cmd --> cd C:\Users\Name\Desktop\nvflash_windows_5.165


This happens with display drivers disabled and enabled.


EDIT: Removed my version of NVFlash and re-unzipped.


Didn't see the link to the validated version.


Everything went well, thanks!

why is it that we have to disable the display driver before starting the flash?


is it a safety precaution?


or is it required, as in it would not work otherwise?


should i disable the iGPU on my Haswell CPU from BIOS before flashing, just in case? or nvflash would only see the NVidia cards, so it does not matter?

with 9xx series you need to either disable it or uninstall drivers . When I got my card, I tried to extract bios with GPU-Z and it crashed system , blank screen so yes its needed .


Don't mess with Intel internal graphics , when you flash you should see it list your vid card .

If you followed the guide 100% correctly, then you shouldn't really be getting this problem. Try again and follow it very closely and if it still doesn't work then report back.

It's almost impossible to brick a card forever. You just need another card that you can use to flash your bricked card back to some bios that works. I know techpowerup has the stock bios' for most 970's.

try to flash with this method on my new Gigabyte G1 GTX 980, my computer just crash andwhen i try to update the bios, i reset it, get three beeps and black screen...

have removed the graphics card, put the onboard as primary and try to flash my saved BIOS with nvflash on CMD boot


and keep showing the message: "no nVidia adapters found"

i just brick my 980?


if i tell to the store i bought that i try to do a bios update with Gigabyte software and my PC crash, they will give me a new one? damm, i'm so sad right now

You must have done something wrong when trying to flash. Or you just have bad luck and your computer is unstable and it crashed during a flash. The only thing I can think of is to boot into Windows with a different GPU and then flash your G1 again.
