I have a Gigabyte z97x-ud3h-bk motherboard with 2 x 1080s in the top two pcix16 lanes (even though they are x8 i believe when both in use) i also have 2 x pcix1s and another pcix16 (though its only really a x4) I am trying to run a riser from any of those slots to a 980 video card. I have good risers (tested on other computers) but when I plug in my 980 and try to boot up the pc i just get a black page, it wont even make it to the bios. I have tried the riser in all 3 of the slots (the 2 pcix1s and the bottom pcix16) but nothing. Do i need a different bios, has anyone else got this to work?
Gigabyte z97x-ud3h-bk wont recognize more than 2 video cards

1 x PCI Express x16 slot, running at x4 (PCIEX4)
* The PCIEX4 slot shares bandwidth with all PCI Express x1 slots. All PCI Express x1 slots will become unavailable when a PCIe x4 expansion card is installed.
* When installing a x4 or above card in the PCIEX4 slot, make sure to set PCIE Slot Configuration (PCH) in BIOS Setup to x4. (Refer to Chapter 2, "BIOS Setup," "Peripherals," for more information.)
You need to go into bios and set the above.
