question for nhc users

I have a couple of questions to ask:
1)
in the cpu speed tab in nhc, is the current power plan settings tool the same as the inbuilt power plan selector in vista?

2)
i was going to undervolt my cpu, when I realised that my cpu hardly ever went above a 6x multiplier (which is the lowest) and that was already at its lowest voltage (0.95v). Would undervolting the higher multipliers make much of a difference on power/ heat etc.. even though they are rarely needed?

3)
What exactly does the power management tool do? i know its says that it decreases cpu speed, but does it do this by underclocking?

4)
Lastly on the voltage tab what does the checkbox mean: use only multiplier 1 and voltage 1. Does this make my cpu only run at the multiplier and voltage that I have ticked above?

cheers for any answers

 

1 ) In a way, yes. Both just change what step your cpu is on.
2 ) Yes, that's the whole point of undervolting. Less power consumed, less heat created.
3 ) Like I said in 1, it just changes the step the cpu stays at.
4 ) Can't help you here, sorry, my cpu isn't supported so I haven't used it.

 

lol i know that's the whole point, but what i was asking is would there be much of a difference made by undervolting the higher multipliers despite my cpu rarely reaching those speeds?

 

Undervolting at say the higher 6 multipliers will do nothing for you, if your processor only runs in the lower 4. To clarify, my example is with a processor which has 10 multipliers.
It is advised to make sure that each multiplier is completely stable before going to the next multiplier. If you set all of the VID's down at the same time, one of them is bound to be too low, resulting in a crash, and you wont know which one it is.
Undervolting does take a while to get it perfect. And when you do, take a screenshot and print it, so that you can put the good settings back after you format or something like that.
