I have been having a few problems with one of my crunchers. I thought I had traced the problem to a bad SATA lead.

However it BSOD yesterday saying it was my video driver, so I updated to to 295.73.

Now I notice 2 errored tasks:

Not sure what the errors are any ideas?

Thank you very helpful!!!

I´m not a cuda guy Bernie but i know 295.x drivers are causing some trouble.
Also i suggest running the Lunatics installer and upgrade to x41g.

With each crime and every kindness we birth our future.

Driver 295.73 works fine when it works, but if you search these (and other BOINC) message boards, you'll find numerous complaints about it.

Specifically, if the graphics card is connected to a monitor by a DVI interface, and the OS is set to blank the monitor for power-saving, then the GPU can become unavailable for CUDA use. That might explain the 'launch failure' in the error messages, if those conditions are satisfied.

Reverting to an earlier driver would solve that particular problem, but leave you to track down the BSOD elsewhere. Neither SATA cables, nor video drivers, 'go off' in my experience - other bits of hardware are more prone to failure.

OK, it just froze, on reboot it seems to have blown away 48 more CUDA tasks!!

I will set to NNT let it finish the MB ones and then decide it's fate, probably retire it, don't have time these days to rebuild them.

It isn't connected via DVI, just a VGA port to a KVM(wonder if that could be a problem)

HAHA, sorry if i'm laughing but i find these : "is a freaky powerspectrum" so funny ^^
who got that idea ?
(just added it to my end post sign ^^)

The boss of course.

as to what a freaky powerspectrum is, I'll quote:

A custom (handwritten) Complex to Complex FFT kernel with embedded direct power spectrum as output.

Bernie, FWIW you are running outdated x32f. Please upgrade to current x41g via the Lunatics v0.39 installler at your earliest convenience. [only if you aren't retireing that rig, of course]

No, the app doesn't cause BSOD, but it probably survives the BSOD better and should have betetr error messages.

'launch failure' is to the best of my knowledge 'I couldn't even start', but doesn't say way. Probably the driver was dead already.

Which driver did you run before you upgraded to 295.73?
