    here are the specs of my home lab:
    -16GB RAM
    -Biostar Hi-Fi H77z
    I have 2 GPUs:
    -AMD 7970
    -nVidia 770

    I am trying to passthrough either of them to a VM to use in gaming, yet I keep failing
    The Windows 7 VM detects the GPUs after installing their drivers but can not use them.
    I installed GPU-Z which sees the GPU but shows Frequency as 0 and games do not run claiming the GPU can not be initialized

    Here is what I tried,
    - I used 4GB of memory to the VM and reserved 8 GB.
    - Reinstalled the OS/drivers multiple times.
    - Switched between the GPUs (AMD and nVidia)
    - Disabled and uninstalled the sVGA driver.
    - Passed through the HDMI audio for each card respectively.

    Edit: My primary display is hooked to the integrated mobo gpu.

    Any feedback would be greatly appreciated.

    I managed to get mine to passs through but cant use the onboard HDMI :( under PCI devices make sure you pass through all PCI devices on the motherboard. That helped for me and i disabled the sVGA adapter in Windows
