Can't use secondary pci-e slot for graphics card

[Evster]

So, I have an asrock x370 pro4 in my latest build. I am planning on wall mounting this build, and I want the graphics card below the motherboard. The main problem is that when my gtx 1070 is in its second pcie 16x slot, the graphics card won't display. Does anyone know how to enable the lower pcie slot for graphics card use?

i never heard such situation, all pci express slots should be enabled all the time

 

specially if you are not using the first slot

 

do you have other pci express cards to see if the slot is working?

I do not currently have any other pcie cards to test with, this is the first build ive done in a while. Its not that the pcie slot doesnt work I dont think, because the lights on the gpu come on, its just that there is no display output

what gpu are you using there?

 

second slot on some motherboards could have speed limitations, power limitations, tjat is why i ask if other cards work on the said slot
