    Default Voltage Question on EX58-UD5

    Just purchased the EX58-UD5 using the i7 940 CPU, and Corsair TR3X3G1600C8D memory.
    I have the system overclocked as follows:

    CPU 3.8 Voltage 1.3750
    Mult 22X
    Bclk 173
    Mem 865 Voltage 1.6680
    Mult 10X
    Unicor 20
    Mem Timing 8-8-8-24

    MY QUESTION:

    Do I have to manually set the various other Voltages (QPI/vtt, CPU PLL, QPI PLL, IOH Core, ICH Core, IOH I/O)?

    Or can I leave these setting on AUTO?

    Does the AUTO setting in the Voltage area adjust the various Voltages based on the setting of the CPU Voltage setting and BCLK Frequency?

    Right now I have the Voltages set as follows:

    QPI/Vtt 1.360
    IOH Core 1.180
    CPU PLL AUTO
    ICH Core AUTO
    IOH I/O AUTO
    QPI PLL AUTO
    PCIE AUTO

    Dram Termination AUTO
    CH-A,B,C Data Ref AUTO
    CH-A,B,C Address VRef AUTO

    The system with these setting, ran Prime 95 25.8.2 for 10 hrs no errors, and running Memtest86+ 2.10 for 20 passes, no errors.

    Thank you for your time.

    I would manually find stable settings for them myself. I dont have X58 board yet, but I do know All previous boards when overclocked WAY Overvolted things. Check with EasyTune and you will likely find your voltages that are in Auto to be WAY to much
