    Hello guys,

    i have some problem about these G.SKILL Rams. I have G.Skill F3-14900CL9-4GBZL (4x4GB) totally 16 GB memory.

    This memory should work 1866MHz and should work with X.M.P right ? and also should work 1.5v?

    So, i go to g.skill website and checked "How to Enable X.M.P on Rampage IV Extreme". Link: https://docs.google.com/document/pub?id=17VKzOB5CL5EtIelw5tGsj2CqjBk3O0OU5VPe6CUoFso&pli=1

    I did everything right but im getting always error.

    when i set xmp settings, i cant open windows. im getting error on bios and it says;

    "System unstable. Your CPU Ratio may be down at 12x due to unsuitable conditions."

    My rams working @ 1.67v + 1600MHz. How i can fix this :(.

    Here is my system:
    CPU: Intel i7-3960x 3 (no o.c-default)
    Motherboard: ASUS Rampage IV Extreme
    Ram: G Skill F3-14900CL9-4GBZL x 4
    BIOS Version:1101
    System BIOS Date: 12/30/2011

    also dimms are seated as shown as Motherboard User's Guide.
