Windows 10: CU Power Settings?

I just upgraded my laptop to the CU and noticed there is a new option under Processor Power Management of Maximum Processor Frequency which is set to 0 MHz by default!

What's this for and how should it be configured?

Windows-10 Creators Update. v1703 Loss of Internet Access

Have a similar problem ever since W10 CU install ~6 months ago. Sometimes I have Ethernet after booting, sometimes I don't. It appears like a race-condition in the process of establishing network connectivity after power on/reboot/wake from Sleep. This
might reflect a race condition CU caused, or a latent race condition in W7 that CU exposed.

MS initially provided me a script to run and capture event since I can reproduce it, but didn't respond to the datafile I provided. Very frustrating to not get a response.

Unfortunately, I'm left to manage it by manually putting my computer in Sleep mode, then immediately wake it. This has a high percentage of success and takes less time than a reboot. Once network connectivity is establish, it never drops until the computer
goes into Sleep or power off.

Same HW never experienced this problem when running W7, or W10 (until CU installed).

Well, I'd say that's quite exciting... (!) -not to say obviously absurd.

Needs reporting (Feedback app).

 

Look through the tutorial and thread, specially this post: Create Custom Power Plan in Windows 10 - Page 2 - Performance Maintenance Tutorials

 

New tutorial to help out. *Smile

Change Maximum Processor Frequency in Windows 10 Hardware Drivers Tutorials

 

Thanks. I hope I didn't prompt you to write this. I would have been clueless what the setting means without the help of this forum!

 

I was meaning to do a tutorial on this anyways, but this just reminded me. *Smile

 

I find these settings a bit ambiguous tbh.

Maximum frequency is a very specific parameter and yet Windows allows you to select values that are meaningless when related to the hardware in use.

There is also 'Maximum processor state' which supposedly allows a set percentage of the systems maximum clock speed to be set. That would achieve the same thing surely ? A 2Ghz clock set to 1Ghz is the same as 50% of maximum. Windows also allows the 2Ghz clock to be set to 5Ghz or whatever which of course it and the rest of the system can not accommodate.

I would assume all these systems and sub systems rely on the hardware being compatible and there is no indication of that. The same problem exists with the wireless adapter settings. Unless the required hardware and drivers are in place then nothing happens when you do alter things in good faith.

 

Yeah, normally you would not need to set this to anything other than the default "0" unless you just want to limit the processor frequency for whatever reason.

You can confirm the frequency change by opening Task Manager, click on the "Performance" tab, and see what it shows for the CPU speed like below. It should be within what you set.

 

Thanks Shawn.

OK, I've done a little test and set the processor frequency to 400Mhz and then followed that up by a pretty intense simulation that should max things out. I have to admit the system felt slow, and I also timed the simulation which took nearly a minute to complete. That was slow compared to around 15 seconds or so I guess.

I then set things back to '0' and re-ran. Back up to speed.

So yes, it does do something although the numbers don't agree with task manager i.e set to 0.4Ghz and its running at 0.77Ghz. The last image is back up to speed.

I'm surprised though. I stand corrected on that one *Smile It does do something.
