has anyone done tests to determine how much this actually changes idle power consumption?


edit: testing it myself, because i'm awesome


default setting, 6 cores idle at desktop: 158-162W


changed to maximum 3 parked cores:

157W, no change really. program recognised changed setting on reboot.

Still get the same idle states if parked or not.

I don't need that powercfg info anymore because the REGF route worked. That should always work regardless of language. Still, interesting you have a custom name on the power profile you are using. I wasn't aware you could even add/remove/rename them without hacks.

The old version you did want 0. Min level and max level was 0 yet default was 10. It was out of range so it erred, disabling parking. This new method leves max at 100 and instead, changes the actual value from what would be 10 to 100. Min and max equal but without erring. The registry is unedited--the power config (not sure where it is actually saved) is modified.

Yeah, the ASRock software changes it.

The naming ? you on about changing ?..

Local Machine \ SYSTEM \ ControlSet001 \ Control \ Power \ User \ PowerSchemes \ bcb8bf4e-1131-47eb-920e-ab4eed020241 ( in this case few other default ones there too )

Then there is 3 keys

Ah! That's where it is! I've been looking for it and looking for it and coming up empty. The program, as it stands, only modifies to current power scheme. I doubt there is demand for manipulating many but if there is, I now know how to do it.

why not just bound it to certain power plan? Like this little app.

Btw its already off in Win8 and Win8.1 @ high performance power plan.
