When I last updated Boinc (6.6.20 seems to be working fine at the mo and with all the discussion probs best not to update!), it said in the installation wizard that GPU computation wouldn't work if you installed Boinc as a service. Running as a service (running as a daemon or protected application mode) is a security issue with Vista. As far as I know it works under XP and Linux fine. As for BOINC upgrades there are a few cuda related fixes after 6.6.30 so if you are running windows it might be worthwhile upgrading to 6.6.36. BOINC blog |

Here is another case, I have 2 gtx295's that usually run a task 10-12 hours. I was supprised to see this yesterday when both had ran for 22 hours and still has 10-20% to go. I'm running 6.6.31 on vista 32bit 4gb ram. I have heard of this but this is the first time I have seen it. |

I'm running 6.6.31 on vista 32bit 4gb ram. Stop and restart BOINC, make sure the science apps stop too ... simplest way is to reboot... This is the dreaded 6.6.20 issue which though less common on later versions is still there. Worse, a friend actually had it hit him on CPU tasks ... so, it is a core problem that we have no clear idea why it is happening. |

If restarting BOINC doesn't help you could / should check if your GPU dropped to 2D clocks (e.g. with GPU-Z). MrS Scanning for our furry friends since Jan 2002 |

"incorrect function. (0x1) - exit code 1 (0x1)" with the app being terminated at a random code line. It's the most common error and mostly related to GPU-OC or defective hardware, but there can be other reasons as well. MrS Scanning for our furry friends since Jan 2002 |
