    DZ87KLT-75K: PCIe GPU stuck in PCIe 1.1 x16 (2.5GT/s) mode!

    Zorlac

      Received my RMA board to fix a few other issues from different threads on this forum. I have done a full clean reformat with Windows 8.1 Pro x64, latest patches and latest drivers. Now I have a new issue...

       

      - My nVIDIA GeForce 780 Ti GPU is only detected as a PCIe 1.1 x16 card running at 2.5GT/s instead of PCIe 3.0 x16 running at 8GT/s. Running the render in GPUZ does not change this. I never had this issue before.

       

      I have tried everything I can think of. I reset the BIOS via F9 and removing the battery, etc., but the problem persists.
