This build should fix BIOS saving on Maxwell GPUs (GM107/GeForce GTX 750 Ti, GM204/GeForce GTX 970/GTX 980).

Underlying reason is that NVFlash can no longer save the BIOS while the graphics driver is running. GPU-Z will prompt you to disable the driver automatically, save the BIOS and then re-enable it.

Please test and feedback. Thoughts on the wording of the prompt?

NVFlash 5.190 doesn't solve the problem when saving BIOS while GPU-Z is running.

ASUS GTX 980 (reference)
No prompt window, and freeze. :(
344.16 WHQL, not Beta.
Can you post a screenshot of the GPU-Z main window? It should prompt for all GPU names starting with "GM"

Whoops, meant to drop my feedback in a couple of days ago but this worked fine on both a single eVGA SC ACX 1.0 GTX 970 and works fine on my current SLI-enabled pair of MSI GTX 970 Gaming cards in the system (two of the same card). VGA driver safely disabled itself briefly even on my 4k MST monitor, low-res around 10 seconds, reverted back to 4K desktop, and showed the save box, spitting out a working BIOS file (tried flashing the same file onto the cards since nvflash does allow you to do so even though you can't flash modded ones yet :p, powered system off for 30 seconds, then turned back on... all remained as it was). This was under both 344.11 WHQL for the MSI card pair, and 344.16 Beta driver for the eVGA card.

Hi all,
Can I kindly ask someone to save and share his original NV reference BIOS, cos I flashed the EVGA SC one and now the one shared over TPU cannot be flashed back for some reason -http://www.techpowerup.com/vgabios/162033/nvidia-gtx980-4096-140826.html
May be some restriction of the OEM NVWinFlash_5.196, but the flashing of EVGA SC bios over the Reference went without any issues...

Thanks in advance

EDIT:
Managed to overcome the issue. Here's the solution if anyone else become into this particular situation.
The card needs to installed as a secondary and then flashed. Because when trying to access the Eprom the screen becomes coloured, seen some of them and nothing happens.

All this with 5.196 NVflash
The most strange to me was when flashed the EVGA SC BIOS this issue wan't present, but backward from it to any other BIOS it appears. May some restriction from them or some kind of incomparability with the flash tool itself.


Hope helped you guys.

EDIT2:
On another note, W1zz
The BIOS saved with this version of GPU-z cannot be flashed with 5.196 NVflash
Saved with Palit tundermaster 2.6 works like a charm - the tool can be found here - http://www.palit.biz/palit/vgapro.php?id=2405 under download section and works with all cards. So if anyone wants to backup the existing rom of his card, that's the proper way

If you need to observe them deeply here are both BIOS saved with GPU-z and Tundermaster and named so respectively inside the archive.
Even though comparing them says they're identical, the NVtflash refuses to flash the one for some reason...at least on my system.

Thanks W1zz this one works fine. I tried using the current version and it corrupted my RAID 0 windows install, had to clean install Windows again:banghead:

Worked fine here on SLI x2 MSI GTX 980 ref

//edit: btw can confirm too nvflash 5.196 doesn't fix the issue at all, I have to disable the nvidia drivers in the device manager prior to use nvflash 5.196 for it to work without error spammings and screen lag until reboot

I also get a black screen when i try to save my vbios on my lenovo y50 with a gtx860m 4gb. I would really appreciate any help I can get because I'm tired of being stuck at a low overclock.
I tried your version but it doesn't work

Using the test version from this thread or the latest 0.8.1 release, I also get the error that reading the BIOS is unsupported on my device. Win7 x64, ForceWare 347.52, and an EVGA GTX970 SSC ACX 2.0+ 04G-P4-3975-KR. Using JoeDirt's NVFlash v5.206.0.1, I am able to manually save the BIOS after disabling the device.
I tried to use that utility but the command line wont execute. When I try to type any command it closes the application.
