    tRFC .......................................
    tRTP .......................................
    tFAW ......................................


    ##Channel A Misc Timing Control##
    Round Trip Latency ...................



    Advanced Voltage Control:

    CPU
    Load Line Calibration ................. [Disabled]
    CPU Vcore ...............................[1.28125]
    QPI/VTT Voltage 1.150v ............(1.295) << May need 1.25-1.45+ depending on QPI speed and ram speed/timings.
    CPU PLL 1.800v .......................(1.8)

    MCH/ICH
    PCIE 1.500v ...........................auto
    QPI PLL 1.100v .......................auto << 1.2-1.3
    IOH Core 1.100v .....................(1.2) << 1.2-1.24 often helps most
    ICH I/O 1.500v .......................auto
    ICH Core 1.1v ........................(1.1) << 1,14

    DRAM
    DRAM Voltage 1.500v ..............1.66 [NOTE: This value is purple in my BIOS] Fine
    DRAM Termination 0.750v [AUTO]
    Ch-A Data VRef. 0.750v [AUTO]
    Ch-B Data VRef. 0.750v [AUTO]
    Ch-C Data VRef. 0.750v [AUTO]
    Ch-A Address VRef. 0.750v [AUTO]
    Ch-B Address VRef. 0.750v [AUTO]
    Ch-C Address VRef. 0.750v [AUTO]

    Windows booted. CPU at idle is 38C, system at 29C. Any issues with the changes I made in red?

    Going to run Prime 95 and Mem test. Is Prime 95 suppose to make CPU temp rise to 62C?

    If you do not use VMware or Virtual machines you can disable virtulization, it can help with stability and a tiny bit with temps

    All looks good above, if you are passing tests no need to raise anything. I'd go ahead and try for 24 hours prime95 if this is the speed you intend to run

    We are always here to help!

    Post back with some results once you get further testing done. Hopefully they will be positive!
