If your CPU frequency is being reduced under load, even at low temperatures, you’re probably experiencing power throttling. On many laptops, you can get rid of it by disabling the Intel Dynamic Platform and Thermal Framework and then setting a higher power limit in the Intel Extreme Tuning Utility.
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.
- 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.
- Now you can use ThrottleStop or Intel XTU to raise the power limits.
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.)

A lot of laptops have further Power Limits controlled by the EC, which is much harder change.
