I am building an ethereum mining rig and have set the whole thing up. I have four graphics cards on PCIE usb risers but am only using one at the moment to get it working. The problem is that the motherboard does not detect the graphics card at all. The graphics card is powered, the fans spin and leds work but the only display device is the onboard one. I've updated the bios and drivers, set pcie lanes to gen1 and gen 2, enabled 4g encoding, and reseated everything. Not sure what else to do. The system itself works fine just cant find my cards.
Motherboard: Asrock z370 killer
Graphics card(s): gtx 1070ti
cpu: Intel Core i3-8100 Coffee
ram: geskill aegis 4gb ddr4
