here's my system:CPU: R7 3800X
mobo: Asrock phantom gaming x x570
GPU: 2x RX480
NVMe in bottom M.2 slot taking up PCIe 5 slot
I just bough myself another RX480 and hooked them in crossfire but the second card is running @ PCIe 1.1 x4 according to gpu-z.
I have the PCIe switch from bios at auto since there is no 2x8 and should work just fine at auto.
Been playing around with this for a couple hours but can't figure out a solution and didn't find any solution online.
Thanks for help!
