Crosshair Hero VI -> pcie config possible?

[lixe]

Hey there,

 

right now I have these pcie cards in my server:

 

pcie1x    usb card for vms

pcie16x  gpu (sapphire7950)

pcie1x    wifi+bt card for macos vm

pcie16x  quad port NIC for pfsense

pcie1x    empty

pcie4x    empty

m.2        ssd for vm

 

I'm thinking about getting a nvidia gpu for gaming some day, but I would like to keep my sapphire for macos, so I would do something like this:

 

pcie1x    usb card for vms

pcie16x  nvidia

pcie1x    wifi+bt card for macos vm

pcie16x  gpu (sapphire7950)

pcie1x    empty

pcie4x    quad port NIC for pfsense (but force in bios to be pcie1x)

m.2        ssd for vm

 

I've tried something like that with an old nvidia9400, but it didn't work. The usb card, wifi+bt and quad NIC weren't recognized by my system, but I don't understand why. Of course I'm not able to run the pcie4x (quad nic) in 4x, because then the pcie1x slots get disabled. But if I set the pcie4x to 1x, shouldn't I at least get all my pcie1x devices? I've read somewhere that some people cut their quad nic so it fits in pcie1x slots, because they seem to not need more than that. But then shouldn't my "planned" system also work?
