    I'm trying to flash Prema's 980M VBIOS for my Clevo P651SG but am encountering this error message when trying to create a backup of my stock VBIOS using GPU-Z. Anyone know how to solve this?

    I think there is a way to save it using NVFLASH. Something on the lines of "-save filename.rom".

    Im not too sure, so please double check this.

    indeed, you have to use NVFLASH to save the vBIOS...

    OK cool thanks everyone. I remember doing it by GPU-Z last time around, I guess NVIDIA has blocked that via drivers or something like that.

    I'll try NVFLASH. Thanks again :)

    Another quick question if I may. Whether I keep the GPU enabled or disabled in device manager I'm getting the following error message:

    I believe that you need to do the flash in a DOS, not a Windows environment.

    You might need to disable your graphics card from the device manager.

    Prevents GPU throttling under normal load and of course and unlocked OC capability...
