Released in 2007, the Intel Dual-Core Xeon 5150 was a CPU designed for use in home and business servers. With features geared specifically toward long uptimes and low thermal outputs, the Xeon series was and continues to be a popular choice for servers. While not designed for overclocking, accomplishing a mild overclock on a Xeon CPU is possible, as long as you have a motherboard with the necessary features.

Things you need
- Xeon 5150
- Motherboard with overclocking features

- Proper cooling
Reboot your computer and enter the BIOS. This is usually done by tapping the "Delete" key at the Power On Self Test screen, but access methods may vary between motherboards. Consult your owner's manual for details.
Use the arrow keys to navigate to the "Advanced Settings, Voltage Settings or Overclocking" section. Press "Enter" to select the heading.
Locate the "FSB or Frontside Bus" setting. The default FSB speed is 333MHz. Press "Enter" to select the option and raise the FSB by 5 to 7MHz. Reboot the computer.
Verify that the machine will boot into your operating system stably. Re-enter the BIOS and continue to raise the FSB setting and test stability until your system will no longer successfully boot into your OS.
Turn your FSB setting down by 10 to 15MHz and restart your computer.
Setting the Overclock
Point your Web browser at the downloads page for Prime95, a free program traditionally used for testing. Download the program file to your desktop and double-click it to begin the installation process. Follow the prompts to install and reboot your computer if prompted.
Double-click the Prime95 shortcut on your desktop to launch the program. Select the "Just Stress Testing" option.
Select the "Blend" option. Allow the test to run for 12 hours, checking in on it periodically. If the test fails on either core, you'll need to turn down your overclock and start the test over. Once your system is "Prime Stable" for 12 hours, your overclock is considered successful.
