I just upgraded to a GA-870A-UD3 and my Asus Xonar d2x will not detect on the new board. It doesn't show up in device manager (as multimedia or a pci bridge) and the drivers will not install. I have tried multiple power connectors, both PCIe slots, and another computer. The card runs fine in two other machines. I don't have any other cards to test the slots with, and I'm kinda at my wits end. Any ideas?
I can't find anything in the manual or the bios about enabling the PCIe slot. I would start talking to gigabyte about my warranty, but I can't really afford to be without the computer for weeks on end.
I cleaned the contacts on the card with alchohol an hour or so before installation and it's a brand new motherboard so there is no dust at all. The new drivers install but the card is still not detected.
Most likely a chipset driver issue download the latest one for your mobo and pay attention to your boards revision # when updating.
That board has five different revisions.
Bottom left hand corner for rev.#
The card only when plugged into the PCIe slot about the graphics card while the card is plugged into the PCIe 16x slot. It wouldn't fit without me removing the shielding only the graphics card. Thanks for the help though.
