    from installing my new gpu in my motherboard the system will not post,
    i keep getting error B2 until I clear the cmos

    if if I go back to my old gpu system boots ok every time.

    I have aver updated the bios on my motherboard and same issue.

    Ok ok my pcie lane is only 2.0 but this card should still work ok.

    Spec is

    Asus Maximus IV Extreme
    Intel Core i7-2600K 3.40GHz
    G.Skill RipJawsX 8GB (2x4GB) DDR3 PC3-12800C8 1600MHz
    Corsair Professional Series AX1200 High Performance 1200W

    new gpu is xox r9 290x black edition
    old gpu was ati 6990

    It does not matter when pcie lane I install to.
