You can switch between the two on the fly. Now, turbo boost is disabled if you are in the "Balanced" profile but enabled if you are in the "High Performance" profile. Set the maximum processor state to 99% on the "Balanced" profile (as described above), but leave it at 100% on the "High Performance" profile. You could instead switch between the "Balanced" and "High Performance" Windows power profiles and use that to control the turbo boost state. We don't have to use the Windows 10 power slider. Switch between "Balanced" and "High Performance" power profiles This post on StackOverflow has answers that describe how to manipulate the slider value from C#/.NET, Python, or PowerShell. Here, I disabled the "classic" power profiles in BatteryMode settings for a simpler view.Īlso, I have produced a command line tool which can adjust the power slider value that works on both Windows 10 and Windows 11, if you would like to work on your own automation. (See the section above, the maximum processor state must also be set to 99%.) Set "Balanced" to disable turbo boost and "Best performance" to enable it. albeit they are presented as radio buttons and not a slider. This app runs as a tray application and allows access to the same settings that the Windows 10 slider gives. You can use the method above, paired with this third-party app BatteryMode. Microsoft removed the power slider and replaced it with a drop-down in Settings under Power Management, so you would have to go digging in there to switch between "Better performance" and "Best performance".)Īlternatives to the power slider (for Windows 11?) (This also works with Windows 11, but it is much less convenient. Moving the power slider to the right will also still remove any limits on the CPU speed. Lower values will further reduce the maximum CPU speed. You can set the maximum processor state value to something lower than 99% if you find that simply disabling turbo boost is not effective in achieving your desired power/heat/noise limit. (The "Maximum processor state" setting is ignored while the "Best performance" profile is active.) Turbo boost speeds will be enabled immediately. If you need more CPU power, just move the power slider to the right. The CPU speed should stay below the CPU's base frequency (probably mid-2 GHz range, depending on the CPU model), no matter what load you throw at it. You can confirm by checking the Task Manager "performance" tab. With this setup, turbo boost is disabled. Note that Windows remembers the power slider setting separately for if you are on AC power or battery power, so you might want to check both. Now, set the power slider that appears when you click the taskbar battery icon to the setting that is second from the right ("better performance"). Set-ItemProperty -Path "$active" -Name "Attributes" -Value '2' $active = $regfolder -replace "HKEY_LOCAL_MACHINE", "HKLM:" Set-ItemProperty -Path "$active2" -Name "Attributes" -Value '2' $active2 = $2ndfolder -replace "HKEY_LOCAL_MACHINE", "HKLM:" $sting77 = "HKLM\SYSTEM\CurrentControlSet\Control\Power\PowerSettings" I'm also including the script here in case something happens to that page. You can just copy/paste it into a PowerShell window running elevated. This page has a PowerShell script that you can run as administrator to restore these options. Side note: If you do not see these power options, then you most likely are running Windows 10 on a system that supports modern standby. Under advanced power settings, set the maximum processor state to 99%. For most people, I think that the first method will work fine. I have a few different methods for this, and I will lay them out sort of from least complex to most complex (.and, they build on each other to some degree). I personally run my laptops with turbo boost disabled, using one of these methods, and I flip turbo boost on only if I need additional CPU power (maybe gaming, intense database work, or some other kind of number crunching). So, here are a few tricks that you can use to enable and disable turbo boost on the fly. You can save yourself some power/heat/noise by having the CPU run at the base clock speed. ![]() Web browsing / office workloads do not really need turbo boost speeds, and there may be times when you would be willing to sacrifice speed for quiet. The CPU does adjust its speed dynamically based on load, but it is (IMO) a bit too eager to hop to high turbo boost speeds when the workload does not call for it. Intel continues to push the turbo power limits higher and higher, which means more heat and noise when the CPU enters high turbo boost states. The audience for this would specifically be laptop users who are concerned about fan noise or surface temperatures in their system. ![]() I've mentioned this in other topics, but I am writing up an article so that I have something to point back to.
