I've being crunching for S@H for a couple of years CPU only, recently got "the bug" and got me a couple of GPUs to speed up the process.
I set up a unit which has sucessfully been running mainly for GPUGrid, and I would like to use it for S@H also, the problem is most of the GPU WUs (SETI@home Enhanced v6.10 (cuda_fermi)) I get run for about 15 seconds and get aborted.
The error messages are:
--------------------------------------------------

I updated Boinc to 7.0.28 and the driver to 301.42 and then to the Beta 304.48 and got the same results...
Any merciful cruncher might have any idea what may be going wrong?
