I've been having issues with GPU passthrough with a ATI/AMD HD5450 - See here

 

I decided to purchase another graphics card, a GTX 960 to try instead. Still having problems though adifferent issue.

When I start the Windows 7 or 10 VM, my monitor changes from 'No Signal' to just a black screen.

Obviously I then can not install Windows, unless I choose VNC.

If I install Windows via VNC, then switch the graphics to the GTX 960 after, I just get 'No Signal'

Graphics card works fine, if I boot to a Windows hard drive instead of the UnRAID USB, so I know that is good (as did the 5450)

 

A couple of times after the blank screen I get Blue Screen PAGE_FAULT_IN_NON_PAGED_AREA

Also have gotten an UnRAID error message a few times, see attachment.

 

I've read about ACS Override option - should this be Yes or No?

Any help is appreciated, really want to get this working

Yes firstly i would try and enable the acs override. (You will need to reboot server after this.) because you gpu is in iommu group 1

/sys/kernel/iommu_groups/1/devices/0000:00:01.0
/sys/kernel/iommu_groups/1/devices/0000:01:00.0
/sys/kernel/iommu_groups/1/devices/0000:01:00.1

 

Your graphics card is ( 01:00.0(gpu graphics)  and 01:00.1 (gpu sound)) but there is also a PCI bridge (00:01.0) these need to be broken up and your graphics card (01:00.0 and 01:00.1) in its own group with no other devices present.

 

Also make sure in your bios that the primary gpu is your onboard graphics not the nvidea. This is important as with nvidea gpus they cant be the primary gpu in the system as unraid needs to use the primary gpu for console. If you try to pass them through as a primary card then you get the black screen as you are getting. (this isnt the case with amd cards they can be passed through as a primary gpu, you just loose the unraid console when they are passed through)

Hello, I have tried the ACS override and still have the same issue. I checked the BIOS and default graphics is set to onboard. The onboard graphics show UnRAID gui on my display.

It's strange because the 5450 was working perfectly on my first ever Windows 10 VM, but since then I can't get anything to work.

Please post your iommu groups and devices after ACS is enabled
