    Rampage iv PCI-Express slot not working for my new GPUs

    Hi, I just bought Two 1070ti that i thought i would SLI into my Rampage iv black motherboard, If i put any card into the first slot to test the cards out, both are working, If i put the second card into the fourth slot for SLI, The board does not detect the gpu, I even tried with my old 980gtx and its not detected in that slot either, Gives me no picture, but the cards leds lights up..

    Ive checked in bios and in SLI only one card is showing up, also in windows only one card, Ive updated the bios, Ive checked the switches on the board to made sure they are all ON and even tried putting them OFF, The third slot dont work for me. Does the PCI-Express slots easily stop working just like that?

    Do i have to do anything in the bios to enable it or whats going on? I tried the second 8x slot and its working with any card.

    Thanks for any help!

    Tried a riser in the port thats not working connected to the card, and the graphic card then works as usual, But why wont the port work when the full card is in the slot? i push it until it locks and the fans spin and lights is on, but computer wont detect it

    Can you please list all your components, if I'm correct for sli the cards need to be in first and third pciex16 slots, if it works off an extender then the card must not be fully seated in the slot
