[almirfiorio]

Dear friends,

I have a Gigabyte card model GA-990FXA-UD3 ..

I have 5 video cards. All connected in pci-e riser with usb cable

There I tried to put the 6 * video card in the 2nd Pci-e 1X  using the 1x-16x riser pci-e extender and the card does not recognize

I tried to change the pci-e adapter 1x-16x and the video card and it did not solve

Can someone help me?

Why ?
but on another note have you tried removing other cards and just trying it by its self?

I believe there is so many lanes shared amongst slots maybe they are overlapping or something
