Sli pci-e problem

Hi all
I have a msi z77a-gd55 motherboard.
The spec for this motherbord is 2 pci-e gen3 (x16 x16) slots and 1 pci-e gen 2 slot (x16).
I have a i7 2600 processor which does not suport gen 3, however surely the cards would default to (x16x16) gen 2.
Both the cards run at x8 gen 2.
is there anything that I can do to get the cards to run at x16?
I have updated all the drivers and bios.

Thanks in advance.

  2. I don't think it works like that. If you use 2 adjacent pci-express x16 slots. They will run at x8 each. The only way you can run both cards at 16x is by having them run in an extreme 4 pci-e motherboard. Then you must have an empty pci express x16 slot beween the cards.
    Performance wise, I don't think it would affect at all. x8 is just as good.
