Great ! Resetting didn't help, but removing/attaching the project did the kick !
Thanks to all for your help ! To be honest: I am ashamed a little bit that I did not even come up with this solution ... one is never too old to learn something in addition ... could be my new signature :-)
Have a good time,
Arthur
I know I am a part of a story that starts long before I can remember and continues long beyond when anyone will remember me [Danny Hillis, Long Now]
Since detaching/reattaching E@H on 19 Aug 2012 (due to the problem of "no more receiving WUs) I have "collected" over 450 invalid validatings ! Picking a random task (e.g. Task ID 304377778) I recognize the following:
- "Checkpoint file unavailable: status.cpt (No such file or directory)"
- "starting from scratch..."
- at the end: "Data processing finished successfully".
All picked details of invalid tasks are showing the same message pattern.
RAC is now very low (about one third of what expected).
GTX 670 GPU usage: 4 parallel processes (each 0.25 CPU + 0.25 GPUs) total about 80% utilization
CPU usage: 5 cores + 4 x 0.25) running total about 80%
System runs 24h/7d
Do I have to deinstall/reinstall BOINC completely ?
Thanks for any help !

Uninstalling & reinstalling BOINC won't help in this since BOINC doesn't do any crunching, it's a managing program. As such, it's not BOINC that's causing your tasks to be invalid. It's the thing that crunches the data that does this. If two other computers manage to do all that data within expected parameters, and yours cannot, then it's really your computer that's not doing things correctly.
So check the videocard, that it isn't overheating or that it hasn't got bulging capacitors. Remember, loss of pixels isn't a problem in a game, but not being able to correctly calculate intricate numbers is a problem here.
Check the videocard drivers, try some other drivers after you've completely cleared out the present ones.
Try running just one task at a time on that GPU, see if it can do that. Only then start increasing one at a time.
Also think about other software/drivers possibly interfering. There are reports coming in that the OpenCL driver for Intel HD Graphics GPUs interferes with the working of some OpenCL applications.
