PCIe x1 Card Not Working in PCIe x16 Slot If that is the case you certainly can use it Any x1, x4 or x16 card will be perfectly happy there If you can find an adapter that is PCIe x16

i have a very similar setup as OP, i have no issues and my two GPUs are in 1st and 3rd x16 slots with soundblaster z in between in the x1 slot if it doesn't

can slot machines be manipulated I've never tested it, but allegedly it will split a single x16 slot into an x8 x4 and x4 in

But yes, a PCIe x1 card will work in x1, x4, or even a x16 slot R

canine carnage slot If it has only one PCI Express x16 slot, the choice is easy, but some motherboards have more than one PCI Express x16 slot for multiple graphics card support

So any card installed in the second slot will result in an 8x8x split If you are using a PCIe Wifi card you should install it in the 1x PCIe
