How to Overclock an Intel Duo CPU
- 1). Power up or reboot your PC. At the POST (Power On Self Test) screen, press the "Delete" key, or the key designated by the motherboard manufacturer, to enter the BIOS (Basic Input/Output System) setup screen. The necessary key is often stated in the POST display.
- 2). Enter the subscreen that involves the CPU settings. The name of the screen differs among manufacturers. Common names are "Advanced Settings" or "Advanced CPU Settings."
- 3). Locate the entry for the CPU FSB (Front Side Bus). Take note of the stock FSB setting. If it is not shown in the BIOS screen, then it should be listed on the CPU box or in the computer's specifications. Increase the FSB setting of the CPU 15 MHz (megahertz) at a time. For example, if the CPU default FSB speed is 200 MHz, then set it to 215 MHz.
- 4). Save your BIOS settings and exit so that the PC reboots. If the computer can complete the POST and load into the operating system without issue, then reboot and increase the FSB another 15 MHz. Repeat these steps until either the operating system fails to load or the computer cannot POST or complete the POST. When any of these situations occur, re-enter the BIOS and reduce the FSB speed 5 MHz at a time until the system can boot up stably.
