H87-G43-GAMING motherboard pci express problem


I have the H87-G43-GAMING motherboard which if you check the manual (page 17)

you will see that it has 2 PCIe 3.0 x16. Recently i bought another graphic card to crossfire and i noticed that the second card runs at only PCIe 2.0 x4. (And yes iam sure that i have put it in the correct slot).

Image of the second card in CCC
Bios shows the same thing.

What is wrong?

Thanks in advanced

    This motherboards PCIe 2.0 ONLY runs at x4 or LOWER, sorry my friend. If you click

    And look at the specifications you will see "PCI Express 2.0 x16 (running at x4)"
