Hallo together,
on almost one of two WU's I get an error on CUDA Computing. It seams that there are tree kind of errors, some lines of the task result file looks like this:
=============================================================================================================================== Task Start and 1. kind of error

CUDA Computing for Milkiway and Asteroids works fine on the machine.
Has anyone an idea what went wrong?

CUDA error 719 seems to be caused by invalid memory access usually. With your version of BOINC not properly detecting NVIDIA memory on 64 bit systems I'd first try to rule that out as the source of failure. You should upgrade BOINC to 7.0.65 or later and see if that helps.
I'm still getting Errors 1007

I'm still getting Errors 1007 and 1008. I'm on Ubuntu Vivid (development release) with BOINC 7.4.23.
