Over the past few days I have had a lot of tasks end up 'Invalid' (2128 currently)

Task 3779990650
Work unit 1614336057
Computer 4226847
Sent 12 Oct 2014, 10:08:00 UTC
Reported 12 Oct 2014, 11:25:09 UTC
Status Completed, marked as invalid
Run time 15.62
Cpu time 10.25
Credit 0.00
Application SETI@home v7 Anonymous platform (ATI GPU)

Any idea why this would be happening and what I might be able to do to fix it?

Thanks

On a quick look i noticed most of the invalids are on device number 2.
Maybe dust bunnies.

Check your temps and clean the fans.

Hmm, perhaps an obvious answer - but how did you tell what device the errors were coming from?

I recently removed my slowest card (5770), and replaced it with a second R9 280x.
So now I have: two R9 280x and a 7850. The 7850 should be dev 2 (assuming they start from 0.)

When you look at the result it will tell you.

Ok, thanks - I never noticed that before.

I've been watching the tasks in BOINC run, and the device 2 tasks seem to run for about 12-15 seconds, get to about 6% then suddenly jump to zero then 100%.

I see nothing in the BOINC event log indicating any sort of errors.

I downloaded the latest Lunatics installer (win64, 0.42) and re-ran to reconfigure, and I am seeing the same results.

I'm not sure if something with the mix of cards is confusing something. I was previously running with one R9 280x, one 7850 and one 5770. I know when I replaced the first 5770 with the first R9 280x a few months ago, I had problems, but that was with every task immediately stopping.

Maybe I need to reinstall everything again, that is what I had to do the last time.

If you didn't reinstall the driver, I'd start there.

I uninstalled BOINC, updated my graphics driver, reinstalled BOINC than re-ran the Lunatics installer.

It looks like that fixed the issue. I haven't had an invalid task since 17:20:46 UTC yesterday.

Keeping my fingers crossed. :-)

Wish the BOINC client would report things like this - I've probably been running this way for a week and didn't notice...

Thanks!
