Check that your CPU, motherboard, RAM, and cooling support overclocking
Update your BIOS/UEFI and chipset drivers
Monitor temperatures, voltages, and stability with trusted tools
Enter BIOS/UEFI and enable XMP/EXPO for RAM if desired
Increase CPU multiplier or core ratio in small steps
Adjust CPU core voltage only as needed and in small increments
Keep power and thermal limits within safe ranges
Save changes and boot into the operating system
Run stress tests and benchmark tests after each change
Watch for crashes, errors, throttling, and excessive heat
If unstable, reduce frequency or voltage and retest
Overclock RAM by raising memory speed and tuning timings gradually
Overclock GPU using manufacturer software in small increments
Maintain strong cooling and good case airflow
Back up important data before making changes
Stop if temperatures, noise, or instability become unacceptable
