    Hello,

    I cannot save BIOS to file with GPU-Z but it works with Gainward EXPERTool.

    Any idea why?

    Cheers.

    What happens if you use NVFlash manually?
    I get an error message as seen in screenshot (with EVGA though) and system becomes unresponsive.
    (I had no time to try with 5.166 yet)

    With NVFlash the dump works but then the system becomes very unresponsive (massive non-stop system lag, only fixed by rebooting, same as GPU-Z)

    BIOS file has the same checksum as the one dumped from Gainward EXPERTool.

    BTW while saving the BIOS with EXPERTool, the monitor goes back to default resolution (800x600 or something) before going back to normal desktop resolution, dunno if that helps!

    Interesting, so EXPERTool deactivates the GPU (respectively the kernel mode driver) temporarily.
    With the same effect like uninstalling the GeForce driver as NVFlash recommends.

    I just downloaded latest Gainward Expertool and it uses NVFlash version 5.165 (unpacks it during runtime to temp directory and deletes afterward)

    Can you try if 5.166 hangs your system too or if it works properly ?

    The 5.166 version i got failed, because it has a vendor lock for Hewlett Packard :(
    5.165 behaves like 5.163, i.e i have to uninstall GeForce driver for successful operations.

    Thank you, I tried this version but the system lagged like hell just like the previous version, had to reboot.

    I uninstalled nVidia drivers and tried again : no problem that time!

    Does that mean the drivers prevent eeprom access?

    If NVIDIA added that warning to the screenshot, then I'd guess that's the case.

    Some kind of GPU engineering fuckup, otherwise they'd have put some workaround into nvflash

    Looks like the issue is gone with 5.190
    Warning message is still there, but no more timeout or freezing with GeForce driver installed

    Code:
    
    NVIDIA Firmware Update Utility (Version 5.190)
    Simplified Version For OEM Only
    
    Adapter: GeForce GTX 750 Ti  (10DE,1380,3842,3757) H:--:NRM B:01,PCI,D:00,F:00
    
    The display may go *BLANK* on and off for up to 10 seconds during access to the EEPROM depending on your display adapter and output device.
    
    Warning: Please make sure no Nvidia Display Driver is installed before continue
      Else update may fail, and system may crash!
