I am trying to consolidate my mining operation and found an old motherboard lying around my place...

Expansion Slots

PCI Express x16 - 2

PCI Express x4 - 1

PCI Express x1 - 1

PCI Slots - 2

Can I use a PCI express x4 to x16 cable and a PCI express x1 to x16 cable to get a total of four graphics cards on this motherboard?
