Hello all, I have a number of Windows boxes, and I've recently acquired a few more video cards, ATI HD4850's and 280X's. I've been a bit undecided as to which cards should go into which machines, due to PCIe slots, case size, PSU limitations, etc. My problem is that when changing from a 4850 to a 280X or vice versa, (and uninstalling and reinstalling the correct drivers), BOINC automatically aborts any and all incoming GPU workunits. I go to my account, and the computer shows the correct video card is recognized by the server. I uninstall and reinstall BOINC, and STILL get auto-aborted workunits. Other than "QUIT SWAPPING CARDS!" does anyone have any advice? :) |

Well, going from a hd4850 to a 280x it fixed itself within an hour. My other machine going from a 280x down to a hd4850 is still aborting after 2 days. I've uninstalled BOINC and the drivers half a dozen times and reinstalled. :-/ |

http://milkyway.cs.rpi.edu/milkyway/results.php?hostid=594815 The error message is: Exit status 201 (0xc9) EXIT_MISSING_COPROC Meaning it can't find your gpu so it's auto aborting the units. Are you sharing the pc with someone else and you each have your own login? I see your gpu also only supports OpenCL 1.0, most projects are going to only version 1.02 and above and you could be caught up in that, I don't remember if MW is one of those or not. Another option is what else is your pc doing while trying to crunch? If it is something that is using the gpu, ie gaming, photoshopping, anything graphics intensive, your gpu may not be available to Boinc when Boinc wants it so the units get aborted. In your settings do you have the box checked to 'use the gpu while the pc is in use'? |

Thanks for looking into it mikey. Milkyway is the last holdout that I'm aware of that still allows the HD4850, which is a shame, because at 200GFLOPS double precision and 110watts max, it's one heck of a performer that can be picked up on ebay for only $30 or less. It's a great option for old dual core PC's with wimpy power supplies. To answer most of your questions with a single response, I got it working again by formatting and installing Windows 10 beta. When that expires in April it will be time to turn off the 'heaters' anyway. :) The PC is only for crunching, although it's located in my daughters room (as a heater), she only uses it when her Macbook isn't yet unpacked for her weekend visit, or the Mac is just a few inches further away than she feels like reaching. :) It's odd that the link to that machine shows it has the card installed, I was given the option to use the GPU in the BOINC Manager, but the error msg says it's missing the coprocessor. I used to think it was a server-side error, sending OpenCL 1.02 tasks, that just took some time to correct, thus I let it run (CPU crunching) for a few days and yet it did not self repair. Not the first time I had the problem, the other times it self corrected in a fair amount of time. Thanks again for trying. |

Have you tried Collatz yet, I think they can take some OLD cards still. http://boinc.thesonntags.com/collatz/ I use Collatz as my backup project on my pc's, meaning I run it when the other projects are down or they are giving me troubles, or even when my teammates are being too slow in their own crunching. He is working thru an intermittent problem though, so he does go down for a day or so here and there. |
