Yeah device manager wont even acknowledge they exist. Here is the set up. Bios is flashed to f22g on gigabytes recommended mining vers although i do not see a minable option in the bios.

you cannot use usb extension to usb risers cables!!!

1. Try a GPU direct to PCIe then restart.
2. If a GPU detected , means a Riser has a problem.
3. Try to Riser (blue) direct to PCIex1 or PCIex16.

For gigabyte motherboard, you MUST find and download special Mining BIOs for your motherboard, google Gigabyte Mining BIOs. Otherwise, you can't enable 4GB decoding, I fought with this for a very long time because this knowledge wasn't stated by gigabyte.
