    This wasn't really answered in the FAQ.

    I've downloaded NHC and am undervolting the CPU, but the FAQ lists the stuff for CHC 1.8. NHC 1.9 has a totally different voltage scale, with gradients between 6x and 13x. Should I just set the 6x and 13x voltages and leave the rest as-is? I figure that would work since most of the time will be spent at either minimum or maximum clock speed.

    Merry Christmas everyone!

    I can't speak for NHC, but the RightMark CPU Clock utility interpolates between the settings that the user defines. As you point out, the CPU normally spends most of its time at either the maximum or minimum speeds, but the mode settings in Power4Gear can override the maximum speed. If the CPU undervolts to below 1.1V at maximum speed, I'm not convinced about the merits of slowing down the CPU which then takes longer to complete a task.

    It depends on the amount of time you want to spend "testing" the stability. It obviously takes longer to test all the incremental steps. I did, though.

    I agree. You'd be surprised how much you actually use those incremental steps. It's worth it to undervolt the whole series, as long as you've got the patience & time.
