    Hi timbo2410,

    How many set of such kit have you installed on this board? (since XMP only guarantee to work at the package they come in)
    Which slots have you installed these DRAM to?
    Also, what was the POST code at the time of failure?

    Please kindly advice.

    regards,

    Hi, I have the two sticks (that are in the kit 2x8gb = 16gb) and they are installed into slots 2 and 4. The error code (on the mobo) is 55.

    Hi timbo2410,

    Your DRAM are in A2/B2, which is the optimal setting on this board for high DRAM clock.
    POST code 55 means the DRAM cannot pass the MRC training cycle conducted by CPU during POST stage.
    Either the CPU or DRAM is unable to take it.

    Try increasing your CPU VCCIO and VCCSA voltage together, as well as the CPU Cache Voltage, and see if this helps.
    If you have raised the BCLK, try lowering it back to 100MHz as well.

    So what volatges should I change to? I did have the cpu running at 4.6 and the ram at 3733 for nearly a year without issue. I cannot ever remember altering voltages other than making sure that the ram was set at 1.35v (as per specs) .. would the different bios change that ??

    Hi timbo2410,

    The following voltages rails will improve you DRAM capability:
    CPU System Agent Boot Voltage
    CPU System Agent Voltage
    CPU VCCIO Boot Voltage
    CPU VCCIO Voltage
    CPU Core Cache Voltage

    Try fine tuning them and see if that helps.

    For ease of work, I will suggest to try resetting your BIOS settings, get the XMP working first before overclocking the others, as XMP is just pre-binned DRAM with settings stored in the SPD (XMP Profile).

    regards,
