Hi,

I have the H87-G43-GAMING motherboard which if you check the manual

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 https://www.dropbox.com/s/8ekej9vlifc2tt6/Capture.PNG
Bios shows the same thing.

What is wrong?

Thanks in advanced
