Not "every" WU gives errors - some are "Completed and validated":

Give us more info - how many GPUs, what type, which of them are in SLI

I just built a new system and was in the same situation as u, I disabled sli and all is good right now. But im not sure if this is going to help u or not as the system i am working on is windows 7, but without disabling sli, it would process one or two work units without any problem, then i would get a slug of computation errors, hope this helps u

I'm having problems with my 8800GTX cards in SLI. After I turned this on and SETI did some work my machine would become unstable. For now I've turned SETI off. Is SETI /w SLI considered to be stable?
