Recently I relocated NV GTX 260 from very unstable host into APU-based one. Unfortunately this disabled embedded APU's GPU. So all AMD GPU tasks now in "Waiting, GPU missing" state. Maybe is it possible to enable both devices? I tried to attach monitor to both - no help. mobo is MSI's A75MA one, OS is Windows Server 2008 x64. Reinstalled AMD VISION Engine Control Center lists only NV card under System information/hardware... [Under display adapters in Device Manager also only NV card listed] SETI apps news We're not gonna fight them. We're gonna transcend them. |

What Settings are in the BIOS for this? If there is no Enable / Disable APU look for "Shared RAM" Set Shared RAM to fixed (e.g. 512 MB) and not to Auto  - ALF - "Find out what you don't do well ..... then don't do it!" :)  |

Depends on BIOS, I have Asus A88X-PLUS and I have both, Ati APU and Nvidia cards running on this host In BIOS there should be something like Integrated Graphics Devices -> Force or something like that. |

Unfortunately, the single BIOS option about video is: Integrated Graphics Devices Configuration with single param: Initiate Graphic Adapter [PEG] and even this one is greyed (unselectable and unchangeable). That's issue with this particular mobo. SETI apps news We're not gonna fight them. We're gonna transcend them. |

I had the same with a Dell Optiplex - GPU or iGPU, not both at once. Downloaded your manual from http://www.manualslib.com/download/820182/Msi-Fm2-A55m-E35-Ser-Ies.html, but it didn't help. |

Page 16 of that manual says it supports dual graphics, but go to the amd website to find the supported combinations. http://www.amd.com/en-us/innovations/software-technologies/technologies-gaming/dual-graphics Seems to suggest it only supports certain AMD cards with the graphics from the igpu enabled as a sort of crossfire. |

Thanks for links and comments. It seems that I need another AMD-only GPU indeed :/ Currently, AMD Radeonâ„¢ Dual Graphics is supported on the AMD A-Series APUs in conjunction with select AMD Radeonâ„¢ R7 series and AMD Radeonâ„¢ HD 6000 series graphics cards used under the Microsoft Windows 7 operating system. Not the right OS also... Well, will try to find "better home" for NV GTX260 then :) SETI apps news We're not gonna fight them. We're gonna transcend them. |

Thanks for links and comments. That is true. Windows Server 2008 is the same level as Windows Vista. SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the [url=http://tinyurl.com/8y46zvu]BP6/VP6 User Group[ |
