Hello. Trying to build my first rig but I cannot get Windows 10 to detect the third GPU. I swapped everything out to make sure all the GPUS and risers are working. Reinstalled the driver. WIN 10 installed in UEFI mode. PSU is more than adequate. Molex connectors are connected to the motherboard.

I set up BIOS on the biostar TB250-BTC motherboard by (1) disabling intelvmx (2) enabling miner mode (3) tolud set to 3.5 (4) PCI-e set to gen 1.

What have I overlooked? Any suggestions welcome. Thanks.
