Welcome to the forums.
Your overclocking options will depend primarily on the motherboard you have. Download CPU-Z from our download section to find out the exact model you have. Post that back here, and we'll try to get you started.
Also, research which power supply you have. You may need to open your case to do so. A strong power supply (Wattage and, more importantly, amperage) is one key to a good OC.
