Underclocking a PC can extend the lifespan of your hardware, reduce heat emission, lower power consumption, enhance system stability, and minimize noise from cooling components.
Steps to Underclock a PC
Access the BIOS Settings: To enter the computer's BIOS (Basic Input Output System) settings, you may need to press specific keys during the boot-up process. Some computers require pressing 'Delete,' 'F2,' or + along with other key combinations while the system undergoes the POST (Power On Self Test) or displays a manufacturer logo.
Adjust Frequency/Voltage Control: Navigate to the 'Frequency/Voltage Control' settings within the BIOS. The BIOS menu usually comprises multiple pages of settings, each corresponding to different aspects of the computer's operation. Use the 'PgDn,' 'PgUp,' or arrow keys to find the page where you can modify these settings.
Navigate to 'CPU Frequency/Voltage Control.'
Use the 'Enter' key or left and right arrow keys to select the value. Adjust the value downward using the arrow keys, + and - keys, or other combinations.
Reduce the CPU Clock Speed: Adjust these settings similarly to the method described above. Keep in mind that performance decreases proportionally with the clock speed.
Decrease the Core Voltage (vCore): Modify these settings in the same manner as described previously. Generally, a 10% reduction in voltage will require a corresponding 10% decrease in clock speed based on the CPU's specifications.
Remember to Save the Changes: Before exiting, ensure that you save the modified settings; otherwise, the previous settings will remain active. If you believe you've made an error, press the 'Esc' key to exit without saving. Note: Some computer BIOS may not include 'Frequency/Voltage Control' settings due to manufacturer restrictions.
Helpful Tips
- Refer to or obtain a printed copy of the system board or computer manual's BIOS section. This section will detail the specific method to access the BIOS, along with comprehensive information about this topic and other settings on the BIOS pages.
- If you encounter boot issues due to incorrect settings, reset the BIOS to its default configuration. This can be done by removing the BIOS battery for approximately ten minutes before reinstalling it, by adjusting a jumper on the system board, or by following other methods outlined in the manual and then powering on the system. Alternatively, look for the 'Reset to Default' option on the BIOS screen, typically located adjacent to the 'Exit' button.
Important Notes
- Underclocking decreases the overall system performance.
- Underclocking may void the system warranty, depending on the manufacturer's policy.
- Ensure you don't set a BIOS password that you might forget. A complete BIOS reset may be necessary to clear a forgotten password. The manual should provide guidance on how to reset forgotten passwords.
