[GUIDE] NVIDIA VBIOS flashing

Recommended Posts

Hello all! I have an M17x R4 with a Clevo 780M GPU, Would it be recommended that I flash the dell vbios as it would be more compatible with my system, or should i just leave it with clevo vbios? Cheers!

Hi again

No luck with this...

Does anybody have a stock 680m vbios? I flashed my card a while back but it wont allow updating the drivers. I'm stuck on 335.23. Everytime i update drivers my card is no longer recognized after a reboot. I have to revert back to 335.23 to get it recognized. I'm on a Clevo P170EM / Sager NP9170

Any help would be appreciated

Anybody?

Hi guys,

I've got a Msi gt70 2od dragon edition with a 780m. And i'd like to flash my Vbios, i also follow your tuto, and i've got an answer?

I watch that the nvflash that you suggest is an old version ( NvFlash 5.127) and now the last version is the ( NvFlash 5.165 ) so please what Nvflash version do i take?

And if ever you suggest me the last/or another version do i make something different of your tuto?

Thanks!

Nico

Commands stay the same for the new versions. So use whatever works. The latest definitely should work perfectly fine.

Thanks man. 1 question

My BIOS at the moment shows "80.04.33.00.10 [MODIFIED]" does that mean the "80.04.33.00.10" is the stock BIOS for my card?

Thanks again for your awesome help

This will come in handy when flashing the 870m. Also I'm having difficulties extracting the current vbios using GPUz, does anyone know of any other utility programs that do the same?

I'm getting the I/O error when I try to run G:\nvflash -6 55.rom (I saved it to G). The file name is less than 8 characters, I've read the forums and so far everyone with that problem has had it fixed by renaming. Nu-uh xD. Any help appreciated. Thanks.

I don't know if this thread is still alive, but I could definitely use some help. I'm trying to flash my 880M on an MSI laptop and I created a bootable dos usb and followed the instructions but it just won't boot into the USB. I tried putting it as number 1 priority in boot order but still nothing. I'm running Wondows 8.1, and solution? Thanks!

if it is on UEFI boot mode try setting it to legacy boot mode in bios.

I had the same problem

What if I have UEFI enabled with legacy oprom enabled? That does show the USB option in boot options
