Anybody who can explain the reason.
A "standard" Wu was finished without a problem.
My FTW finishes a long WU in a bit more than 8 hrs without a problem at the moment.
Something wrong with my card or what ?

Not the most technical person here, but these two this come to mind, since it does not appear to be driver related:

1) Are you running CPU intensive apps while running GPU, if so, I would reccomend leaving one core/or thread free for GPU to use.

2) I also see that you have OC this device, and this can also cause problems, trying bringing down the OC, and also keep track of temperatures.

I hope this helps.

Running Docking@Home during our Stampede and the card is factory OCed and nothing more.
