Thread: Southbridge voltage in GA-EX58-UD5

    Question Southbridge voltage in GA-EX58-UD5

    I have been advised to "increase the southbridge voltage a notch or two" by members in another forum (OCZ) to possibly fix an intermittent freezing problem with my OCZ Vertex SSD. I have a GA-EX58-UD5 board, running BIOS 7F at optimized settings with no overclocking. My question is which BIOS parameter controls the southbridge voltage ? If I had to guess, I would say it was ICH I/O ??

    My current settings are :

    IOH Core 1.100v [Auto]
    ICH I/O 1.500v [Auto]
    ICH Core 1.100v [Auto]

    Any help or advice would be appreaciated

    ICH Core, I'd try 1.14-1.2 should be plenty with your card and SSD

    You can also adjust ICH I/O to 1.58 if you like, I run 1.58/1.18-1.2 often
