Why Your Processor Always Runs at a Low Frequency

If you've noticed that your processor is constantly running at a low frequency, there could be several factors at play. A consistently low CPU frequency can negatively impact your computer’s performance, slowing down tasks and reducing overall efficiency. Let's explore the possible reasons behind this issue and the steps you can take to resolve it.

Main Reasons for Low CPU Frequency

1. Power Saving Mode

One of the most common reasons for a low processor frequency is an active power-saving mode. In both Windows settings and BIOS, there are modes that limit the CPU's performance to conserve energy, which results in a reduced frequency. Check your current power profile and switch to "High Performance" mode to see if it improves the situation.

2. CPU Overheating

If the CPU temperature exceeds the safe limit, the system automatically lowers the frequency to prevent overheating. This is a built-in safeguard to protect your hardware from damage. Check your cooling system, clean the fans from dust, and, if necessary, replace the thermal paste.

3. BIOS and UEFI Settings

Settings within the BIOS or UEFI may restrict the CPU frequency to improve system stability or conserve energy. Try accessing BIOS to see if there are any limitations in place, and, if necessary, reset the settings to default.

4. Power Supply Issues

Inadequate power supply can also lead to a lower CPU frequency. If the power supply unit isn’t delivering the required voltage, it can affect the CPU’s performance. Make sure that your power supply is adequate for your computer's needs.

5. Software Limitations

Some applications and drivers can set limits on CPU frequency. For example, certain antivirus software or monitoring programs may reduce the frequency for safety or stability reasons. Check your software settings and disable any features that might be restricting the CPU.

How to Increase Your CPU Frequency

If you’ve identified a cause for the low frequency, try these steps to improve your CPU's performance:

  • Switch to the “High Performance” power plan in your settings.
  • Inspect the cooling system and replace thermal paste if needed.
  • Reset BIOS or UEFI settings to default.
  • Ensure your power supply unit is of adequate capacity.
  • Disable frequency-limiting features in software and drivers.
