RX480 crossfire issues


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!
