Raedon RX 560 runs at x8 Native

[DannyApple]

Hi Everyone,

I have a issue with my Asus ROG-STRIX-RX560-O4G-GAMING it runs at x8 native mode which is supposed to run at x16 mode.

Tried the same card in an AMD setup runs at x8 mode, removed all the Nvme drive, PCIe wifi card still runs at x8 mode. tried the secondary x8 slot runs at x4 mode

Is this something to do with RX560 or am i missing out on something, No drivers or any kext loaded. Please advise.

x8 is correct - See Wikipedia.
