Disabling Overclocking in BIOS/UEFI Settings

To stop overclocking your CPU, the most direct and reliable method is to disable any overclocking settings in your motherboard’s BIOS or UEFI firmware. This process involves accessing the BIOS/UEFI during system startup and reverting the CPU settings to their default values.

Upon entering the BIOS/UEFI interface, navigate to the advanced CPU configuration or overclocking section. Depending on your motherboard manufacturer, this might be labeled as “OC Tweaker,” “Ai Tweaker,” “Extreme Tweaker,” or simply “Overclocking.”

Look for the following options and reset them accordingly:

  • CPU Multiplier/Ratio: Set this back to “Auto” or the default value specified by your CPU model.
  • CPU Base Clock (BCLK): Ensure this is set to the standard 100 MHz or the default base clock.
  • Voltage Settings (Vcore): Return voltage controls to “Auto” or default to prevent unnecessarily high voltages.
  • XMP Profiles for RAM: While not CPU overclocking per se, disabling XMP can help stabilize the system by running memory at default speeds.

After making these changes, save and exit the BIOS/UEFI. The system will reboot with stock CPU settings, effectively stopping overclocking.

Using Software Utilities to Revert CPU Overclocking

If you prefer not to enter BIOS/UEFI, or require a quick method while the operating system is running, certain software utilities can disable overclocking settings applied within Windows.

Popular tools include:

  • Intel Extreme Tuning Utility (XTU): Allows modification and resetting of Intel CPU parameters.
  • AMD Ryzen Master: Provides control over AMD Ryzen processors, including reverting overclocking.
  • MSI Afterburner: Primarily for GPUs but can monitor CPU parameters and reset overclocking profiles.
  • ThrottleStop: Useful for disabling turbo or undervolting, indirectly influencing overclocking effects.

These utilities typically offer a “reset to default” or “apply stock settings” option. Use this feature to restore CPU clock speeds and voltages to manufacturer defaults without rebooting.

Restoring Default Windows Power Plans

Overclocking can sometimes be enabled or enhanced by aggressive power profiles in Windows. Restoring the default power plans can help ensure the CPU runs at standard frequencies.

Steps to restore default power plans:

  • Open Command Prompt as Administrator.
  • Run the command:

`powercfg -restoredefaultschemes`

This action removes any custom or modified power plans and reinstates the original Windows settings, which do not encourage overclocking or high-performance CPU states beyond default specifications.

Resetting CMOS to Clear Overclocking Settings

If BIOS settings are inaccessible or the system behaves unpredictably after overclocking, clearing the CMOS can reset all firmware configurations, including overclocking.

Methods to reset CMOS:

  • Using the CMOS Jumper: Locate the jumper on the motherboard labeled CLR_CMOS or JBAT1, move it to the reset position for a few seconds, then return it.
  • Removing the CMOS Battery: Power down the PC, unplug it, and remove the coin-cell battery on the motherboard for approximately 5–10 minutes, then reinsert it.
  • BIOS Reset Button: Some modern motherboards include a dedicated reset button on the rear I/O panel.

After clearing CMOS, BIOS settings return to factory defaults, stopping any overclocking configurations.
