Daniel Dobrowolski - maybe you can really help here if you still have the CH6. I am not the only one convinced that this board is not correctly enumerating the chipset-driven PCIe slots. In my case it seems that if there are two similar cards (I have two USB3 cards both with the same NEC controller chip) in these slots then the BIOS will only enable one of them. BIOS v1201, Win10 x64, Ryzen 1800X, no OC.
--> Can you run a test to verify or disprove that specifically? Or just run some tests with combinations of cards?
Thanks in advance. I have contacted Asus support with no result, but if you can verify a simple BIOS problem they may pay attention and fix it.
(My 2008 Asus Rampage Formula mobo identifies these cards with no problems so the fact that there is an issue and that Asus can solve it if they want to seems obvious.)
The Crosshair VI Hero died on me. I've got it, but it's dead Jim.
