  1. Hi, I can't find the settings for the CPU voltage in my BIOS. I know it's a H board, but can I lower my CPU voltage? If so how?

    The H77 chipset does not allow you to alter CPU voltages. That can only be done on a Z77 motherboard/chipset.

    Yea, on Intel you have to have a Z-series board for that.

    Your Asus P8Z77-V board has an EPU switch (also settable in BIOS), when enabled it tunes the system for maximum efficiency, including reducing voltages. While you still can't directly set voltages, this may accomplish what you're trying to do.
    EDIT - I meant P8H77-V, I'm just so used to writing my own model name! His board also has an EPU switch, just no TPU chip.

    Hood, the OP doesn't have a P8Z77-V motherboard. He has a P8H77-V.
