Change Maximum Processor Frequency in Windows 10

Gibt es auch einen Code, um die Mindestgeschwindigkeit der CPU per Eingabeaufforderung zu ändern?

Is there also a code to change the minimum speed of the CPU by prompting?

Hello, and welcome to Ten Forums.

If you like, there's a Minimum processor state setting you could use for this.

Add or Remove Minimum processor state from Power Options in Windows

Hi @Brink!
Perhaps something has changed with powercfg settings since you wrote this tutorial . I mean, I tried today (2020-04-23) and instead of <Mhz> it is the usual <percent%> value (ranging from 0-100). My windows 10 is v1909, 18363.720.
By the way, there are plenty of /aliases (so many GUID are now no longer necessary).
Keep up with this outstanding work!

Hello saosilvestre,

It sounds like you are seeing Maximum processor state with a percentage instead of Maximum Processor Frequency with Mhz in this tutorial.

Yeah, using GUID is an old school habit.

Hello Everyone!
I am new in the forum. I read the post because i was having some problems with the laptop (i will bring it to fix eventually), but because i need it right now, i was trying to keep it as save as possible and i was thinking about lowering the Max Freq of the CPU.
Just lowering the % of work fo the CPU is not working, 98% goes below the basic freq of my I7-7000HQ and 99% is like nothing had changed. So i try to add the Max freq in the battery options and set it up to 3000Mhz, but after a stress test it always goes higher, then i tried option two, with the prompt( for me called WIndow powershell), and had this message:
PS C:\WINDOWS\system32> powercfg -setacvalueindex SCHEME_CURRENT 54533251-82be-4824-96c1-47b60b740d00 75b0ae3f-bce0-45a7-8c89-c9611c25e100 <3000>

i Substituted the Mhz for 3000, maybe it has something to do with what Saosilvestre was saying, but i really dont have any idea.
Can somebody help me?
Thanks beforehand!!

Hello HappyRider, and welcome to Ten Forums.

The command should be this below with 3000 instead <3000> at the end.

powercfg -setacvalueindex SCHEME_CURRENT 54533251-82be-4824-96c1-47b60b740d00 75b0ae3f-bce0-45a7-8c89-c9611c25e100 3000

Using this command will be the same as setting it using Option 1 in Power Options though.

Thank you Brink!! My mistake, you were right, it was only 3000 and did not give me any error now, but how you said, it was like the first option, i try to limit the frequency, even below 2.8GHz and when i run the stress test keep going up until 3.5 GHz.
Any idea why it could be?

It could be the stress test program not obeying the Windows setting in Power Options.

You could check your BIOS settings to see if you may be able to limit the CPU on a hardware level instead, but most laptops will not have an option for this.
