Hi, I have a PC with 2 GFX cards GPU0 is a nVidia 9800GTX+ which I want BONIC to use. GPU1 is a Passively cooled nVidia 9400 which I dont want Bonic to use. I tried to follow the wiki to force bonic to leave my 9400 alone by creating a cc_config.xml file and saving it to my bonic install directory c:/Program Files/Bonic/. <cc_config> <log_flags> </log_flags> <options> <<ignore_cuda_dev>1</ignore_cuda_dev> </options> </cc_config> After saving, I clicked on the Advanced tab of Bonic and made it read the local config file but it has not worked. When I unsuspended the queued work CUDA apps continue to work on both GPU's. Can anyone see what I am doing wrong or point me in the right direction? |

You're got an extra < in the <<ignore_cuda_dev>1</ignore_cuda_dev> line You don't say what version of Boinc you're using, you'll need Boinc 6.10.19 or later, reading from the config file won't work for this, you'll need to fully restart Boinc. Claggy |

Thanks you for your reply. BONIC version installed is 6.10.58 Windows x64 cc_config.xml now looks like this. <cc_config> <log_flags> </log_flags> <options> <ignore_cuda_dev>1</ignore_cuda_dev> </options> </cc_config> I rebooted and BONIC is still using both GFX cards. I also dont see anything in the message tab relating to disabling GPU1. Not sure why its not working. |

Sorry, i didn't notice, the cc_config.xml needs to placed in the Boinc Data directory, not the Program Install location, the exact location is shown in your Startup messages, the folder is likely to be hidden, so you'll need to unhide it, Claggy |

Thank you so much! Its working perfectly now and reporting GPU1 to be ignored in the start up messages. I Just need to make sure the 9400 hasn't melted anything important. :) |
