My capture card not working and can't force PCIE 8x on x470 K4 Fatal1ty

I just bought a Datapath Vision E1S pcie 4x capture card and when I try to capture from it, my system reboots instantly. I believe the main issue was that I'm using too many PCIE lanes. I have tested this in an older AMD APU pc and it worked fine.

On my main system, I tried setting 2 8x PCIE in the bios but it didn't seem to work and I set GEN 1 and GEN 2 for pcie. Tried a bunch of combos of moving my gpu and datapath card around and I cant get my system to run in 8x. I did try to remove the gpu and leave the datapath card in while I removed in. I did see the datapath card pull a image but then the system locked up I think. I might have only been seeing this image because of remote desktop.

Is there anyway to force the 8x or is something in my system just conflicting? Should I try rolling back bios version or updating to 3.40? I know it says 3.40 I cant roll back anymore after and I thought it was only changes for new cpus. Thanks!
