- Enter the BIOS by rebooting your computer and hitting the [DEL] or the [F2] key. The exact steps will vary according to your BIOS type and version. Refer to the motherboard manual to help locate the FSB frequency and the CPU voltage settings.
- Increase the CPU FSB frequency in small increments of, say, 2 MHz. Change the CPU Speed/ Voltage Settings to ‘Manual’ to let you change them. Note: Throughout this exercise, monitor your system temperatures and voltages very closely. It is critical that they remain within limits for your system to run reliably. Failing to do so will result in shortening the life of your processor or even failure. It is important to start out your overclocking at the rated settings and work your way up in small increments
- Save your settings and reboot the machine. The PC should boot normally. Check for any signs of instability. Run a CPU-intensive program or game like Half-Life 2 to stress the CPU and make sure it is working fine.
- Reboot and enter the BIOS again. Increase the CPU voltage, again in small increments. Restart and repeat the previous step. Continue till you feel the machine has been pushed to its limits. Reboot and enter the BIOS again. Increase the CPU voltage, again in small increments. Restart and repeat the step 4. Continue the process till you feel the machine has been pushed to its limits. A stable overclocked system is one that has the right balance between CPU FSB, voltage and bus speed settings. Overclocking is achieved by trial and error and we cannot over emphasize the importance of safety.
