So I just got my 7,1 and inserted GTX1080 Founders Edition with Belkin cable (mini 4 pin to 8pin). The graphics card is not detected in Windows 10. RX580 (aftermarket) was detected fine in both Windows 10 and Catalina using the same Belkin cable (I didn't detach the cable either when I replaced it with GTX1080). I know Nvidia is no longer detected in Catalina but why not on Windows 10? Anything I did wrong?

Which slot are you putting the 1080 in?

So interestingly I put in slot 3 didn't work, I put in slot 4 and it worked. I'm not sure if I didn't insert it properly but I did see the GEFORCE light turn on. And interestingly, 580X aftermarket card worked on slot 3.

W5700X is currently taking up slot 1 & 2 right now.
