I installed the card in the PCIe X1 slot and tried to install the ASUS driver package that I downloaded from the web site and the drivers would not install. I kept getting the error that I did not have the right hardware to install those drivers. I went to the device manager and the sound card does not even show up even after I refresh it by searching for new hardware. I guess that I am out of luck. I know that the sound card is good because I had been using it for years and it worked fine in the Rampage II Extreme board. Thanks for taking the time to answer my post, I really appreciate the effort. I guess that I will just have to buy another sound card.... Bummer.
