I replaced my RX 560 with an RX 470. I installed drivers but boinc isn't seeing my new GPU. I saw an article from 2010 that said to copy Code: <cc_config> <options> <use_all_gpus>1</use_all_gpus> </options> </cc_config> into Notepad and Save as cc_config.xml to BoincData folder Where is the BoincData folder in Windows 10? Thanks! |

I found it: C:\ProgramData\BOINC\projects\setiathome.berkeley.edu |

I added the file, but BOINC still isn't using the second GPU |

Now BOINC switched which GPU was being used! Still only 1 being used though. My monitor is plugged in to the RX 570, which BOINC was using previously. Now BOINC is running on the RX 470, and the RX 570 is not being used by BOINC. |

Anyone have any ideas? |

So here's the history: I had a RX 560 originally. Then I added an RX 570 and BOINC used both GPUs no problem. I decided to upgrade the RX 560 to an RX 470. I used just the RX 570 for a while while until the RX 470 came. I installed the RX 470, updated the drivers, restarted the computer and BOINC only used the RX 570. I added the CC_config file to boincdata folder and then restarted my PC twice. BOINC started using the RX 470 and not the RX 570 now. |

Are you sure when you save the file you set the notepath not to save with the .txt extension? |

Make sure that "Show Hidden Files/Folders" is Enabled, AND "Show Extensions..." If this was NOT done previously, then, (as Juan suggests), your "cc_config.xml" File is REALLY "cc_config.xml.txt" Once the above changes are made, and from within Notepad, when you Save - ALWAYS choose "Save As". THEN for File Type make sure that ALL or *.* is showing, and then save the File as "cc_config.xml" <<--- (NO .txt at the end...) TL TimeLord04 Have TARDIS, will travel... Come along K-9!

When changing GPUs always uninstall & clean out the old drivers. Use something like Display Driver Uninstaller for that, from Windows Safe Mode. Then boot to normal mode and install the new drivers. Even when the system doesn't ask for it, reboot at the end of the installation. You ought to be able to install the same drivers for both GPUs, if both are AMD and GCN GPUs. I found it: C:\ProgramData\BOINC\projects\setiathome.berkeley.eduThat's not where the cc_config.xml file should go. cc_config.xml is a BOINC configuration file, not a Seti file. So it should go into the BOINC Data directory, C:\ProgramData\BOINC Make sure first there isn't already such a file there, and that it doesn't already contain a line for <use_all_gpus>, because if you add your own line at the top of the file, and there's another at the bottom with an opposite switch, the last line is used. If a line is present, change its value from 0 to 1 and save the file. But to be able to use the <use_all_gpus> switch, BOINC should first detect both GPUs, which it isn't yet doing. When in doubt, post the first 30 or so lines of your BOINC messages (CTRL+SHIFT+E). |

Make sure that "Show Hidden Files/Folders" is Enabled, AND "Show Extensions..." I think I did save it as .txt I opened it and did "Save As" all files. Now its full name is cc_config.xml. However, it didn't solve the problem. I'm going to try a clean install of the drivers next. Thank you all for your help! I'll report back, |

I read that's it's a hidden file. |

I read that's it's a hidden file.No, it isn't. But C:\ProgramData\ (and hence BOINC\) is a hidden folder. |
