Disable CPU Throttling function

The overclocking protection feature of CPU Throttling is a problem faced by laptop owners who have bought a new power supply instead of a proprietary one. The PC suddenly starts working much worse, even with small loads. Further you will read how to return it to a normal state.

What is CPU Throttling Overheating Detected

CPU Throttling is a function of reducing PC temperature: due to throttling, the frequency of the processor is reduced and overheating is avoided. Such a mechanism is provided on some laptops to protect them from damage. A message with the text: “CPU Throttling Overheating Detected” appears when a non-original power supply is connected, but remember that this may not be true. Even if you purchased a power supply that meets all technical requirements and does not threaten the processor, such notification may occur. You can disable this feature, but first you should check the power supply first:

  1. Compare the data of the new power supply with the original one: all the indicators are the same. Power, voltage and current must be absolutely identical. At the slightest discrepancy, it is better to refuse to use the power supply.
  2. Ensure that it is in good condition and that there are no electricity problems in your house.
  3. Check if the laptop is clogged with dust from inside: perhaps the problem is not in the power supply, but in real overheating.

Just in case, vacuum the laptop's air vent or spray compressed air from the cartridge into it to prevent the processor temperature from rising.

What to do and how to remove CPU throttling

To disable throttling is only if you are absolutely sure of the need for such a step. If something is wrong with the power supply or power supply, a processor without protection can be burned. To turn off the function, you have to use a third-party program ThrottleStop. It can not be called easy to use, but it is effective. Download the software from the developer’s site and run it - no installation is required. Next, a window will appear with numerous settings: they are selected depending on the type of processor and laptop manufacturer. For Dell equipment, there is a separate BD PROCHOT section - remove the label from it, and do not forget to enable the permanent program action via the Turn On and Save button, in order for the settings to be saved. You can disable the throttling of the Intel processor and others using the Clock Modulation, Chipset Modulation, Set Multiplier, Turbo Boost or C1E options. Let us dwell on each of them:

  • Clock Modulation, Chipset Modulation will help limit throttling, if it is initiated directly by the CPU or Motherboard: correcting the values ​​will increase productivity. Look at what the Mod column shows in the general form: everywhere there should be a number 100. If not, set it to the left, opposite the parameter names, the indicators to 100%, and the problem will disappear.
  • Set Multiplier allows you to manually adjust the desired performance of the processor. Here we are interested in the “Multiplier” item - set it to 80-90% so that the performance is high enough, but not the maximum. A mark of 100% can lead to overheating.
  • Turbo Boost does not always help, but it can periodically increase the CPU frequency when there is such a need, for example, while using resource-intensive programs. If you do not want to drastically change the performance indicators, try enabling this function and working - perhaps it will be enough.
  • C1E is an option that should reduce performance only in standby mode when you are not using a laptop, but sometimes it does not work correctly and extends even to the period of operation. Try to turn it off - sometimes it solves the problem.
