When running resource-intensive applications, you may notice unexplained drops in your CPU speed. These drops are often caused by CPU throttling, a power-saving feature in Windows in which the CPU clock speed drops under load. You can prevent these drops by changing the power management settings in Windows, although you also may need to also disable the power management feature in your computer's BIOS.
Open Power Options
Click the Start button in Windows 10, select Control Panel, and click Power Options.
Change Advanced Power Settings
Click Change Plan Settings next to the power plan you're using for your PC and then click Change Advanced Power Settings. Expand the Processor Power Management listing and then expand Minimum Processor State. Change this setting to 100%. This causes your CPU to kick in at 100 percent of its clock speed whenever it runs a process and to stay at 100 percent until the process is complete. It does not mean your CPU stays at full throttle all the time.
Set System Cooling Policy
Scroll down to the System Cooling Policy listing, expand it and make sure it's set to Active. An active cooling policy turns on the CPU fan before the processor approaches its maximum temperature, decreasing the chances that the processor will slow down to avoid overheating during times of heavy use. Click OK to apply the changes and close the dialog box.
Change BIOS Settings
For those who are comfortable changing your computer's BIOS settings, reboot your system to access your computer's BIOS. Watch the screen for the key you must press (e.g. F1 or F2) to enter the settings menu. Any qualified computer technician can also do this for you.
Look for a power management feature in the BIOS, disable it and save the settings. These features may slow down your CPU at times to save power. Look for a setting labeled with something generic such as 'Power Management' or with something more specific such as 'Enhanced Intel Speedstep Technology,' 'Enhanced C1,' 'Enhanced Halt State' or 'Cool'n'Quiet.' Some BIOS software, particularly in laptops, may not allow you to change this setting. Refer to your computer documentation for more specific information.

- Overheating also can cause drops in CPU performance. If you continue experiencing problems, make sure the inside of your computer is well-ventilated and that the fans are working properly. Also make sure the fan and heat sinks are clear of dust and lint.

ThrottleStop is a small application designed to monitor for and correct the three main types of CPU throttling that are being used on many laptop computers.The left side of ThrottleStop contains a variety of options which can be used to bypass CPU throttling and on the right side is a Monitoring panel that shows you the current state of each thread on your CPU.Some laptops are using clock modulation and multiplier reductions to lower the performance and power consumption of your computer. This is done deliberately to either allow your computer to run cooler or to allow your laptop to operate with a power adapter that is not sufficient to fully power your laptop and recharge its battery at the same time.When using ThrottleStop, it is strongly recommended to monitor power consumption at the wall with a Kill-a-Watt meter or similar device and make sure that you don't exceed the power capabilities of your power adapter. Use of ThrottleStop to bypass these throttling schemes is at your own risk and can result in permanent damage to your power adapter or computer or both which may not be covered by your warranty.
