GTX 750TI Problem

[SpaceInvaderOne]

Hi. I just bought a zotac 750ti 2 gb card to replace my hd 6450 which i have been using together with a 4550 on my unraid system with gpu passthrough on all my vms/ win7,8 10 and open elc.

 

I can only get 750ti to work if on second pci express port with another gpu in the primary port. opelc works but no sound and also it cant see shares although it is assigned an ip from the router.

 

The windows machines i can get to boot but again the sound has issues stuttering. I thought i would passthrough the rom file so i booted into windows 7 native not a vm. Ran gpuz and downloaded the gpu bios.

 

However when i add the bios file to the xml the vm will not boot. Any ideas why?

 

thanks
