Change Maximum Processor Frequency in Windows 10

Hi!

Someone asked about where to find the aliases. It is quite simple. Just open an elevated command prompt and type: powercfg /aliases

The list above is for Windows 10 v1909 18363.720.

Thank you.

Hi @Brink -

I have Intel SpeedStep disabled in my desktop BIOS. I can totally agree if it was a laptop.

Found this on a website. Do you agree with it?

"While it is safe to disable SpeedStep, it is not something I would recommend doing. SpeedStep increases or decreases CPU frequency based on CPU load, and it can be a saver of electricity and also reduces heat and noise of the PC, by slowing down the CPU when it is not being stressed. Unless you are doing a short term extreme overclock, I would recommend keeping SpeedStep enabled. This does not, however, mean that disabling SpeedStep will damage the CPU - it will only make the PC use more electricity and produce more heat, hence an average consumer should leave it enabled."

Just curious.

Hey Brian,

I'd say that was a pretty accurate description. It pretty much depends on how you use the computer for what may work best for you though.

A HA!!! This thread led me to a fix for a drastic problem that I have wasted *many* days & nights over the past two months. I found the thread searching for PROCTHROTTLEMAX, getting ready to do some deep surgery in the Registry.

Let me explain the symptoms of my particular problem, and then the simple solution which the above post unintentionally led me to.

SYMPTOMS: My laptop was sometime blazing fast and other times *unworkably* slow. I was mainly using ProcessExplorer to monitor, and then troubleshoot when it was pegged at 100% CPU use. An earlier a-ha moment was yesterday when I installed NZXT's Cam system monitor. I found that my CPU was usually running at 2200 MHz, but whenever I came out of hibernation under battery power, the CPU was always throttled to 800 MHz. But coming out of hibernation under AC power, the CPU was never throttled. In other words, when de-hibernating under battery power even though ProcessExplorer can say (at times) the the CPU is loaded 100%, in fact that "100%" is only 36% of the CPU's nameplate capacity (i.e. 36% is the new 100%). Also, I was running on the "Maximum Performance" Windows power option. Note that my processor is a 2400 MHz i5-6200U.

SOLUTION: I ran Task Manager as shown in the prior post. However my duo-core CPU was showing as only 1 core plus one logical processor. (Some tools I had used in earlier troubleshooting showed two CPUs, but I didn't realize they should be showing four.) Some Web research led me to the CPU boot setting in MSCONFIG. The correct setting is shown in the attached screen shot: the CPU box is not ticked, and there is a greyed-out "1" (representing one CPU on the motherboard). My incorrect setting had the box ticked, and "2" processors indicated (having confused "cores" with "processors"). See screen shot.


THREE NEW OUTCOMES - ALL GOOD ONES: (1) Now in Task Manager and the Cam program I am running on 4 CPUs (2 cores, two logical) and at 2700 MHz (not the previously shown 2200 MHz, on my -- now, that's weird) . (2) Coming out of hibernation on battery power, I'm running unthrottled at 2700 MHz. (3) I now have more choices in the Window's Power Options. Until this change, under Processor Power Management there were options only for System Cooling Policy. Now there also are options shown for Minimum and Maximum Processor State. (In another thread started by Brink, there was puzzlement over the loss of these settings in later Win10 updates - maybe this helps solve that too?)

So have you used ThrottleStop? I if you did, you might have found the problem out sooner. Either way, good find.
