Important: this is no longer necessary; ThrottleStop‘s “Disable and Lock Power Limits” option overrides DPTF. If that doesn’t work, try the following.
If your CPU frequency is being reduced under load, even at low temperatures, you’re probably experiencing power throttling. Most of the time, you can solve this by disabling or raising the power limits, and disabling DPTF explicitly is not required. But sometimes, you need to disable Intel’s Dynamic Platform and Thermal Framework, which tries to set the power limit dynamically on your behalf.
Your laptop may have an option to disable DPTF in the BIOS menu. If not:
- Install NoDPTF.reg to prevent Windows from automatically reinstalling DPTF.
- This registry file is from my NoDPTF project repository on GitHub.
- In Device Manager, find all the devices whose names start with "Intel(R) Dynamic Platform and Thermal Framework". They may be in the "System devices" list. Right click on each and "Uninstall device". Check "Delete the driver software for this device" whenever available.
This method only works if you have Group Policy Editor (Windows 10 Pro, Enterprise, Education).
- Open the Group Policy Editor.
- Go to Computer Configuration/Administrative Templates/System/Device Installation/Device Installation Restrictions.
- Open "Prevent installation of devices that match any of these device IDs".
- Click "Enabled".
- Checkmark "Also apply to matching devices that are already installed".
- Click "Show".
- Now you will enter the device ID of each of the DPTF-related devices. You can find them all by finding those devices in Device Manager/System Devices or by copying all the values from NoDPTF.reg.
- Click “OK” and "OK" again. You should see each of those devices become "Unknown device" in Device Manager. That means they are disabled.
Keep in mind: the removal of DPTF will not inherently change anything until you raise the power limits using ThrottleStop or Intel XTU.
If any DPTF devices are still present, please tell me their hardware IDs in the comments. (To check hardware ID: right click on the device, Properties, Details, select “Hardware Ids” in the drop-down menu.)
- In Registry Editor, delete HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DeviceInstall\Restrictions.
