Just installed Nvidia 8400GS into my motherboard ASRock B85M Pro4. For some reason PCI devices doesn't see the graphics card but the card works (it's spinning and worked on other computers builds before). I'm not sure if I need to do anything on the bios but so far nothing. I am on onboard graphics now (hdmi from motherboard will show the unraid console screen) and the vga card is still plugged in. What is preventing it from detecting the card? The card itself, motherboard, bios, or unraid? I was planning to use vga to run a Ubuntu VM and output to hdmi (Plex/Steam streaming)

 

Here are my information:

Have you read the unRIAD 6 manual and this section:

 

      http://lime-technology.com/wiki/index.php/UnRAID_Manual_6#Assigning_Graphics_Devices_to_Virtual_Machines_.28GPU_Pass_Through.29

 

I don't know if it addresses your issue but it is a place to start.  There is also more information in the upgrade WIKI which you can see here:

Thanks but sadly I have not reach the VM part yet, since it's not being detected by unraid.. I guess the only other option is to get another gpu and test it out, just to make sure that slot is working

Since your motherboard has two x16 slots, have you tried it in the other one?

Not yet, since the other slot (pcie2) is occupied by a sata card. I will try to swap the pcie2 (sata) and the pcie3 (gpu) cards this weekend and see how it goes. If it works then.. it's better than nothing! :\
