Windows 7: Minimum Processor State

ryanfx · 13 Feb 2010

Hello everyone,

First post here, first things first, Hi!

Secondly, I'm experiencing an issue with my laptop running 7 Home Premium 64. My model/make is NV5927U/Gateway and I am experiencing some pretty annoying issues.

Anyways, I am hearing "cpu whine" or more correctly, toroidal coils which are vibrating very rapidly causing interference with the speakers. My question is this:

Whenever my processor goes into the sleep state with no jobs, that's when the computer whines, however; when the processor is actually doing something the whine goes away entirely. I looked online and found solutions regarding rmclock but I'd prefer finding some more natural solution.

I went into the power management and found "Minimum Processor State" which I believe should fix my problem since it will keep the processor at a higher clock. No dice. After looking at the cpu utilization it seems as if the cpu completely ignores this minimum processor state setting and lets the cpu go to 0 anyways. Is there a known bug with 7 that allows this? Can one of you confirm that the cpu simply goes to zero despite any setting you enter?

Thanks for your help, and please let me know if I should provide you with anymore information. Yes I've updated drivers / windows updates.

The Minimum Processors State only controls the clock speed, reducing it to use less power and create less heat. It does not keep the processor working at 100% utilization if there is nothing to work on.

doesn't the minimum processor clock state increase clock speed?

the maximum should limit it top, the minimum should ensure it never falls below a minimum.

Either way it doesn't matter. It won't solve your problem.

Could you please elaborate on why it won't? The cpu whines when it enters state C3, or C4. Shouldn't keeping the cpu at a minimum hertz prevent it from entering one of these states?
