Launched in the first quarter of 2008, the Wolfdale series Intel E5300 presents a viable candidate for overclocking for several reasons. The E5300, a dual-core and dual-thread Pentium central processing unit (CPU), provides hobbyists, gamers, graphics designers and engineers with multiple access points to change the basic input output system (BIOS) settings through software manipulation. The 2.6 gigahertz (GHz) clockspeed settings, combined with a relatively low 800 megahertz (MHz) front-side bus (FSB) frequency, a 13 bus/core ratio, a high temperature tolerance, relatively low cost and a wide voltage range provide a reasonable set of overclocking variables.

Things you need
- Overclocking software
Check to make sure you have the latest BIOS version. Your current version number appears at the top of the BIOS page. You can open the BIOS by depressing one or more keys immediately after turning on the computer. Check the manufacturer's website for the correct key combination. Compare your BIOS version to the latest version number found on the motherboard manufacturer's website. Download the latest BIOS update if it is not already installed.
Level and polish (lap) the contact surface of your CPU's heat sink. Find detailed instructions for lapping your heatsink on any of several websites such as overclockersclub.com or neoseeker.com.
Optimise your computer case cooling fan configuration by cleaning and lubricating installed units and adding additional fans wherever possible. Keeping the CPU and motherboard cool allows you to achieve higher stable clock speeds.
Download and install overclocking software such as CPU-Z, ClockGen, SetFSB or something similar that allows you to adjust CPU speed, voltage and FSB frequency.
Download and install stressing software to test your overclocked CPU's stability. Examples are Everest and Prime95.
Open your overclocking software and raise the E5300 CPU clock speed from 2.6 to 2.8 GHz.
Raise the CPU voltage from .85 volts (V) to 1V, or approximately 10 per cent.
Increase the FSB frequency multiple from 13 to 16. Reboot the computer and check for stability for at least one hour. Your overclocking software displays ambient internal case temperature and CPU surface temperature. The CPU surface temperature should not rise above 71.1 degrees Celsius. If it does, shut down your computer, scale the settings back 10 per cent and retry.
Repeat these steps and increase all settings by 5 to 10 per cent. Check for stability after each boost.
Tips and warnings
- Invest in the best heatsink you can afford and install as many cooling fans as your computer case will support. Make sure you run a minimum 500 watt power supply. Optimise the amount of random access memory (RAM); the more memory the CPU can draw to operate, the cooler it will run.
- Do not over do your overclock. Even at the price as of May 2011 price, quickly burning up E5300s at £39 apiece can prove expensive. Do not delay turning off your computer if you see a temperature spike above 71.1C. Mere seconds can make the difference between resetting the BIOS and replacing the CPU and -- too often -- the entire motherboard.
