nvidia and amd use two different drivers to access the cards in the system ... you cannot mix and match them ... at least not from a 'standard' point of view ... so suggestion is simple - remove the amd card and put it in a different system ( or build a small system ) that will be used for mining on that card alone ... it required catalyst drivers and ( im assuming from the description ) you have nvidia drivers installed ... btw - depending on what you are mining - you are MUCH better off using one of the forks of ccminer for the nvidia mining ... the most universal one is sp's fork - but there are a few that are suited to different mining - like tpruvot and djm34 etc ... sp-mod is here - https://bitcointalk.org/index.php?topic=826901 ... #crysx |

Try creating a fake display by detecting then extending the main display to the nvidia cards. |

On Linux you can easily mine with AMD and nvidia cards together. Use AMD as primary then install cuda without opengl.

dont they both need different drivers? ... i tried this a while ago and it just refused to work ... #crysx |

1) Ensure that all cards work - GPU-Z/Device Manager/AfterBurner 2) Start miner on AMD GPU only, use --gpu-platform. If it won't work at all - re-install AMD drivers. If it will work but won't display temp/speeds or enter "3d mode" when mining - you need dummy plug. R9 290x can use simple DVI dummy with resistors. Or you can plug monitor in it. nvidia and amd use two different drivers to access the cards in the system ...
you cannot mix and match them ... at least not from a 'standard' point of view ...
Yeah.. right..  |

Yeah.. right.. for all the time ive been mining - i have never seen this done successfully ... especially with windows ... now i have  ... the farm will still be sticking with linux - but damn good to see ... btw - how did you get all 10 gpus in the one system without a BIOS change? ... #crysx |

And i have to say. Congrats. Been able to get 8 running on linux. Had no more space to connect any extra gpu's. And yes, i would also love to know what mobo that is. Gotta go get me one of those for sure Greetings |

Those must be 4 7990s and I'll guess 3-4 psus are being used.. |

Mobo? HA! What about the power supply?
Those must be 4 7990s and I'll guess 3-4 psus are being used.. Original post by alexbg21: Still no success with more than 8 AMD GPU on windows. I think kernel file makes problem, but success with 4 X 7990 and two GTX 970 plus CPU mining - all 45 Mhs on X11 !!! 8 GPU limit per windows is MYTH. This is absolutely not true!!! These days i will buy pcie expander card and will try to add three more GTX 970  In windows 8.1 i did not connect any monitor like it was it windows 7. Everithing works perfect. 8+GPU works only on GIGABYTE 990FXA-UD3 Rev. 4.0 (Revision 1.2/2.0/3.0 and GYGABYTE 990FXA-UD5 which i tested have bios issue for 8+GPU). Asrock H81PRO BTC - only 7 GPU!!! I think this board have bios bug or something like that. Till now GIGABYTE 990FXA-UD3 Rev. 4.0 is best for support multiple GPU but do not try to switch more than 10 GPU - South bridge will die !!! 2 of my board are death now, trying to switch on 11th GPU https://imageshack.com/i/exWBHEs3jhttps://imageshack.com/i/kqcGXV1Hj------------------------------------------- windows 8 gpu limit 8 gpu limit Maximum Gpus windows 8 Windows GPU limit ------------------------------------------- As i understood problem is in these two files: amdkmdag.sys c:\windows\system32\drivers\atikmdag.sys amdkmdap.sys c:\windows\system32\drivers\atikmdap.sys Yes - 4x 7990 and 2x750ti |
