    Your CPU is PCI Express Revision 2.0, sorry. You need a CPU that is 3.0 to get 3.0.


    Your looking at around 180.00 to go with a 3.0 CPU the closest is a Intel Core i5-3350P. Its also a lot faster then what you have now.

    Are you in the top slot, you have a 2.0 x1 slot, but that's not the slot you should be using. Also check the BIOS, look for GEN settings.

    What is telling you x1, did you run GPU-Z ?
