Message 1745357 - Posted: 28 Nov 2015, 6:21:53 UTC

I recently replaced my failing video card with the ASUS version of Nvidia GTX 960. It seemed to be working fine for several days, but now I'm seeing some very odd running work units.

They download with an estimated running time of about 11 minutes. After running for a few minutes, the estimate climbs to between 30 and 48 hours. Left to run, these will fail with a Computation Error. The last such work unit was 04my11ae.26235.2525.11.12.15_1.

Can anyone tell me if this is a problem with my system, or if this is a set of the work unites produced by a bad splitter earlier in the month? Any help is gratefully appreciated.

Thanks,
++PLS

Looks like you are running them in a lot less than that, so possibly the Boinc system is just confused about your estimates. This should fix itself, sortof, over time, as long as they don;t start auto aborting. I only say 'sortof' because there are some known and unknown situations that can make the estimates freak out.

You did get some faulty tasks before, which show as invalid (maybe you have more on board still) but they are relatively short running.

Did you see any GPU load when the task was 'hang'?
Next time you may try 'Snooze GPU' for a few seconds to see if that will make the task 'go'
