So, I got my new build up and running (Brett-i7) Gigabyte Z170X-UD5, i7-6700K, 32GB DDR4 2400mhz, R9-380 and HD7870, Windows 10. BOINC only sees the R9 Device Manager shows both GPU's fine. CCC shows both, but says 7870 "disabled" I've googled it and only thing I find is with Crossfire enabled, CCC will show the second GPU disabled and only activate when needed. I do not see where I can disable Crossfire in CCC. Any ideas. The combo worked fine in my old PC GA-P55A-UDP, i5-750 machine. Thanks, Brett |

Nothing to do with crossfire - don't waste time with that. What you need to do is to edit, or create, BOINC's cc_config.xml file to include an option line <use_all_gpus>1</use_all_gpus> Since you're using BOINC v7.6.9, the easiest way is to tweak BOINC's set of Event log options slightly (cpu_sched is a good one to add): that will write out a complete cc_config.xml file, with <use_all_gpus> set to the default zero. Change it to one, save it, and restart BOINC. |

Tried adding <use_all_gpus>1</use_all_gpus> to my cc_config.xml Still no joy and under my computers still only showing the one GPU. |

Did you restart BOINC? Just adding the line to cc_config.xml won't fix this. Doing a 'read config files'won't do it either as GPU detection only happens at boinc startup. |

Nothing to do with crossfire - don't waste time with that. CCC shows both, but says 7870 "disabled" You missed an important line, Catalyst Control Center is reporting that the other GPU is disabled, not BOINC. |

Yes, I restarted. Still not running. Windows device manager show two display adapters, the R9-380 and the HD7870, and both say "The device is working properly" It's when I go into CCC, and hardware under info, that it says the HD7870 is disabled. A number of on-line posts say there is an option in CCC to turn off Crossfire. My CCC does not have that option that I can find. |

Windows device manager show two display adapters, the R9-380 and the HD7870, and both say "The device is working properly" If you right click on the Desktop, then Screen resolution, does it show 2 displays there? Grant Darwin NT |

plug a monitor into the disabled card crossfire should be disabled since its different cards I came down with a bad case of i don't give a crap |

OK, I plugged in a second monitor, and almost voila! CCC has now enabled the adapter. Restarted BOINC and the startup log shows both adapters but says the 7870 "ignored by config" So I don't have something right in my config file. |

Houston we have lift off. Opened the config file, found the GPU entry and it was set to "0", changed to "1" bingo. All GPU working. |

Thanks for the help, do have another issue. In old box (brett-PC) where I pulled the R9 and 7870, I put my old 4870 in. Installed the legacy driver and all looks good BOINMC shows it , but I have been requested tasks for GPU and not getting any. When I did the swap, I ended up abandoning all existing GPU tasks. Could that have any effect in not getting any? Thanks again |

First, we cannot see your computer names, only the SETI@Home assigned numbers. Second, did you abandon the tasks manually, or did it happen automatically when BOINC detected the removal of the GPU? Either way round it should not affect you getting new tasks, what will have a bigger impact is the shortage of tasks just now - it wold appear that there was a bit of a glitch with the splitters a short time back and they are now trying hard to catch up (well, as hard as the splitters every try...)

Restart BOINC and take a look at the first 20-30 lines in the log. This should tell you if everything is working correctly on your computer. Just a note: we cannot see your computer names so it can be hard to tell which one you are referring to. We can only see your computer ID. I see we were both typing at the same time Bob.

I have been doing a little googling and found some that point to going back to older drivers causes some issues. Any thoughts about completely uninstalling previous drivers. Could that be it? |

Thanks TBar, that did the trick. Still don't have any GPU tasks, but I'm sure that is due to the shortage. Now just a little patience.

Pay dirt. Right before my very eyes, 52 GPU tasks appeared. Thanks all. Cheers, Brett |
