this motherboard is amazing and support pci 3.




what i should do?

pcie is backwards compatible
your card will not utilize pcie 3.0 speeds anyways

What CPU do you have in it?

 

[alvine]

Today's dual GPU's don't even use more than half of PCI-Express 2.0 bandwidth yet.

Not to worry.
More correctly,while the GTX680 can use 3.0, but will not be slowed down even by pci-e 2.0.

Here are some benchmarks.

Honestly don't worry about it your card can't fully saturate a PCIE 2.0 or PCIE 3.0 slot. I remeber some site did a benchmark test pci 2.0 vs 3.0 and there was 1 FPS difference at most.

contact the mb vendor. on the newer z77 mb the pci mutiplexer chip is not the same on the x79 mb.
PLX PEX 8747 chip

if your mb has the n200 chipset it may be older chipset and cant do 3.0 or there a defect in your chipset.
