Go into bios and search for FSB or BCLK, increasing those values overclock your cpu but may cause instability, overheating and other problems, also you need to raise Vcore if you plan to overclock a lot.If you have never overclock again be carefull and increase those values by a small amount also you must stress test your cpu at the end.(If you dont know what you are doing i dont recomend you to overclock your cpu, you may permanent damage your components,Overclocking requires some skills and knowledge and special hardware,you cpu is not made for overclocking.)
