GTX 780 BAd Work Units?

My Rig folded properly all night without issues. I believe this matter is resolved. Many thanks to all.

The audio driver is for audio over hdmi, should be no reason for it to affect folding.

It wouldn't be the first time that an audio driver/device set up through Windows Device Manager has interfered with folding. There are a number of device ID's in the GPUs.txt list that are blacklisting an audio device that has caused problems in the past.

@s/j - One thing to watch out for, there have been a number of reports in the past of updates to Windows video drivers causing the GPU index values to change once again. Just mentioning it for you to keep in mind when updated drivers become available in the future.

Thank you Joe for the advice, I will manage Patch Tuesdays very closely. Your other advice was also helpful to uninstall and then reinstall the client when adding GPU rather than adding a slot. Like you say, that way the client can assign things up properly.
