Windows 10: Windows is power throttling for no reason.

Damon_203 · Sep 13, 2018

So I have been using the Intel Extreme Tuning Utility recently and it just started power throttling while I am idle. Anyone know why? I usually get a CPU clock speed of 3.8 - 4 GHz but now all I get is 2.20 which is the lowest my i7 processor can go. I have tried restarting my computer and decreasing the voltage offset but nothing works. Just making sure I didn't brake anything.

Introducing Power Throttling in Windows 10

You may remember some of our January power experiments we mentioned in Build 15002’s release notes. Power Throttling was one of those experiments, and showed up to 11% savings in CPU power consumption for some of the most strenuous use cases. We’ve been hard at work making improvements and listening to Windows Insider feedback since then, so this capability should help many of you see a nice boost in battery life!

Note: Power Throttling is currently available only for processors with Intel’s Speed Shift technology, available in Intel’s 6th-gen (and beyond) Core processors – we’re working on expanding support to other processors as well over the next few months.

How does it work? To give great performance to the apps you’re using, while at the same time power throttling background work, we built a sophisticated detection system into Windows. The OS identifies work that is important to you (apps in the foreground, apps playing music, as well as other categories of important work we infer from the demands of running apps and the apps the user interacts with). While this detection works well for most apps, if you happen to notice an app that is negatively impacted by Power Throttling, we really want to know!! You can do 3 things:

1. Provide feedback! Please run the Feedback Hub and file feedback under the Power and Battery > Throttled Applications category

2. Control power throttling system-wide, using the Power Slider

3. Opt individual apps out from Power Throttling:

Go to Battery Settings (Settings > System > Battery).

Select your app.

Note that benchmark results may vary with power throttling turned on. While most benchmarks run fine and produce great performance results, some benchmark processes may be affected by throttling. Our general recommendation is to always run performance benchmarks while plugged in, as power throttling does not apply in that case.

Developer note: Power throttling is designed to work well with applications out of the box, but we recognize that in some cases, application developers may be able to provide additional power savings by having more fine-grained control over Power Throttling. We will have APIs to provide more fine grained control in upcoming flights. Please make sure to watch out for API updates on MSDN.

*Power throttling is a temporary working name for this capability and may change during the course of the development cycle for the next release of Windows.

Thanks,

Power Throttling in Windows 10

So I came across this page:

http://www.thewindowsclub.com/power-...ing-windows-10

that talks about which processes use power throttling and when I follow the directions and click select columns I do not see an option to tick Power Throttling. Win 10 Pro. Anyone else who does not see the Power Throttling option? TIA.

Hi, what is your Windows build? If you have not upgraded to the "Fall creator update" build 1709, you won't see it.
