Windows 10: CPU speed throttling Maximum Processor State does not work anymore

First,

I used the CPU speed limitation and system cooling policy=passive to keep down the fan noise.

This worked fine, for a long time.

But now I suddenly get this behaviour:


Maximum Processor State: 80% or less -> CPU speed does not exceed 1.6 Ghz anymore!

Maximum Processor State 90% -> CPU speed unthrottled 3.8 GHz


=> It is kind of a binary behaviour now either unthrotteled CPU or limit to 1.6 Ghz

I hope this will be fixed again.







Best regards

how to enable "maximum processor state"

If you have an Intel CPU you can disable C-States in BIOS. This will place your CPU in the "maximum processor state" at all times.

 

Why is the default maximum processor power state of power saver 100%?

Hi,

Thank you for posting your query on Microsoft Community.

Your Minimum Processor State option to above the minimum (such as 50%) is if you are running very CPU intensive programs and they would not function well at lower CPU states.

Processors do not require a steady stream of information to function at a certain speed. For example if you have a 2.0ghz CPU and you set the minimum processor state to 50%, the lowest it will ever drop to is 1.0ghz, even at idle.

With your minimum set to 50% and maximum set to 100%, the actual speed it runs will stay between those two values and current battery life amount will factor into what speed it chooses to run at with an average of 75%.

If you set your minimum to 5% and maximum to 100% it will drop extremely low to preserve battery life.

Hope this information was helpful and do let us know if you need further assistance. We will be glad to assist.

 

Maximum processor state?

Hi all,

I'm not a techie so please bear with me.

I just purchased a new laptop. HP with Windows 10 OS. AMD A6-9220 Dual-Core processor and 4 gig of ram. After it's initial setup and removing all the bloatware/crapware, most of the apps and disabling everything in the startup, I noticed that when the computer was not really doing much or much of anything, the fan was running a lot and on high, thus being noisy and annoying, and blowing out very warm air, with the corner area by the vents getting quite warm. At times the processor utilization was at or near 100% and at it's maximum burst (acceleration) speed of 2.9 ghz. Base clock speed is 2.5 ghz.

I checked some forums and on YouTube, and found one video in which the uploader talked about having a problem with his laptop's fan running almost constantly on high after he had updated from Windows 8.1 to 10.

He showed in the video that he seemingly had found a simple/quick solution. Go to Power Options, change Plan settings, change Advanced power settings, Processor power management, Maximum processor state ====>Change Plugged in setting default from 100% to 30%.

He said that immediately worked for him and the fan became barely audible and running normally. He mentioned he was not a gamer and didn't know if the change would affect gaming but for what he used his laptop for the change seemed to work fine.

Cut to the chase: I made the same adjustment and it worked as it did for him. I haven't noticed any real change in performance/speed, duly noting here that the laptop is a budget (entry level) model and isn't exactly zippy to begin with. I was wondering just exactly what minimum and maximum processor state means and what does lowering the maximum state to 30% actually do and is it in anyway harmful/deterimental or not, short-term or long-term?

Thanks in advance for any/all input.
