I just bought a GTX 660ti superclocked card to use in my EVGA Z-68 FTW motherboard. The problem I am having is this.....when i install the new card, I get an A2 code error message " IDE detect" message. Will the 660 ti sc card which is PCIE 3.0 work in my motherboard which is PCIE 2.0? Thanks for any help in advance.
