  1. Best answer
    Download the motherboard manual from Asus support.
    (page 2-11) Change Memory Clock Mode from [Auto] to [Manual].
    (page 2-12) Set Memory Clock Speed to [800MHz].
    (page 2-12) Set the first four DRAM Timing numbers.

    For example, Kingston KHX1600C9D3K2/8GX

    Each module kit has been tested to run at DDR3-1600 at a low
    latency timing of 9-9-9-27 at 1.65V. The SPDs are programmed
    to JEDEC standard latency DDR3-1333 timing of 9-9-9 at 1.5V.

    The DRAM Timings are 9-9-9-27 in this example.

    If your memory DRAM Voltage is higher than 1.5v as in the example it is 1.65v, you need to set that option too.

    (page 2-12) Memory Over Voltage [1.65]
    Save and Exit BIOS
