I have a question I have been researching for days on. I have a MSI z97 gaming 5 board with 7 PCI slots. All the slots work fine for GPU's as I have an identical board with 7 AMD GPU's running. The other board I have 7 NVidia cards, GTX 1060 3GB. With 6 cards this board runs fine, when I put in the 7th, I can see it when I do a lspci -v I can see all 7 NVidia cards. Here is a difference between a working card and non working card.
Output from a working card:

The Subsystem: Device ID is what seems to jump out at me the most. So the board sees it but cannot give enough resources to use it?
Any chance someone knows what I can do to get this card working?
