    Does NHC perform suitable undervolting for the novice?

    I just started reading the thread here about undervolting, and while it's still a little over my head(still don't know what multipliers are/do) it had me wondering. I have run NHC from the beginning, and I've looked at all the options it has, as well as what it does while running. I mostly have it set to "Dynamic Switching" when plugged it. In this setup, does it perform suitable undervolting to reap the benefits as described with other methods( http://forum.notebookreview.com/showthread.php?t=235824 )?

    Use RMClock to undervolt the processor. It should work fine with the T2500. Following the guide step-by-step would be alot easier.

    Suitable undervolting - Just check that the voltages are actually being changed and are fixed for each multiplier by stressing the cores using Orthos/Prime95. You can use CPU-Z 1.41 or CoreTemp to monitor the voltages.

    Ok, but what about NHC? To be honest, I'd rather not have to do anything more if it does a suitable job already. When in dynamic switching, and little load, the freq sits around 900mhz and the voltage shows 0.95 with an average cpu temp of 38degC. With load, the freq and voltage changes accordingly, so I assume I'm reaping all the benefits of undervolting, no?

    If at the highest mutliplier, the voltage is 1.1750V, then No. And what stops the processor from going down to 800MHz ?

    Try getting the lowest possible voltage for each multiplier, and then stress test that particular multiplier, to see if it is stable or not.

    (In RMClock, you need to do this only for the lowest and highest multiplier, and auto-adjust the VIDs for the rest of the multipliers)
