    I am posting this quickly in order to help anyone else out there with a non-resuming Gigabyte motherboard, and also for the benefit of any Google searches.

    I have spent the last few days troubleshooting and tweaking my overclock voltages and freqs to get full stability - as my system would not properly resume from S3 sleep/standby. Instead it would power back on with a black screen and was forced to reset CMOS each time.

    System includes:
    P55a-ud4 motherboard, with F15 bios
    i5 750.
    4gb 1600mhz DDR3
    5770
    Win7 and Mac osx86 dual booted.

    Basically after all that, it turns out that the culprit was a setting totally unrelated to voltages or the overclock at all. Under Integrated Peripherals, ensure that Onboard USB 3.0 Controller is Enabled! I always turn off all chipsets and functions that I don't use, however this setting is vital if you wish to resume a sleeping system properly.

    Hope this helps someone out there
