Hi Guys and Girls


I have a problem which might be nothing, not sure. This is the first crossfire machine I have built, I have a gigabyte z77m-d3h motherboard and have x2 rx470's running in crossfire in it - when checking with gpu-z I see the second card is reporting PCIex16@x4 whilst the first is reporting @x16?


Is there something not working right? Do I lose performance?


Thank you for the help, below is image of stress test done showing clearly 1 at x 16 and 1 at x 4:
