Hi everyone,

I am using my pc for BOINC, but want to try overclocking. When I am sure it is stable, I want use it for BOINC.
Now I was wondering the following: suppose I got the false impression that it was stable (but it is not stable), will I be notified if I produce erroneous results?
It would be waste to let my PC crunch if the results it produced are wrong, but I didn't know they are wrong.

Thanks!

You can login to your user account at the individual project sites and see how your computers are doing. You can look for the tasks and see if the results have been validated or if your computer has produced invalids or errors.

Overclocking, even if "stable", can produce slightly different results for the climate models being run by climateprediction.net, compared to a computer running at rated speed.
And, as climate is weather over a long period, and weather is what is know as a "chaotic system", there's no way to tell if the sometimes subtle differences produced in "attribution" studies is due to what is happening, or if it's just the computer.

Which is why overclocking isn't a good idea for this project, so please don't run cpdn if you overclock.

And if your results are suspect when analysed, they'll just be discarded, without notification.

This backward communication from project's validator to BOINC client then to user is long-awaited feature but not implemented so far AFAIK.

Best you could do is to run some project like SETI that uses BOINC notice mechanism to inform users if app sees suspect results during computations.
