  1. X16 mode is default for GPU! You sure you have it in the right slot or the top one?

    my motherboard can only run 4x mode or 1x mode so I don't know which one I should use, and which one gives me best performance.

    the motherboard has 3 lanes and I have the gpu on the first lane
  3. Your board has 2 x X16 slots and 1 x X4 slot! http://www.newegg.com/Product/Product.aspx?Item=N82E16813131821
    Primary slot is the one closest to the CPU the bottom slot only supports max X4! You have the card in the wrong slot!

    so in which color should I put the card in? beige or brown or black? so confused because in the manual it says:
    first slot = PCIe 3.0 x16_1 slot ( single at x16 or dual at x8/x8 mode)
    second slot = PcIe 3.0 x16_2slot
    third slot = PCIe 2.0 x16_slot 3 (max. at 4x mode)
  5. Beige is the primary GPU slot! Brown is the second slot and the black one is the Ver 2.0 slot that runs at X4.

    that means I should put it in the beige?

    Yes! Then it should run at X16 for max performance!
