Up the multiplier to x18, keep the base clock at 200Mhz [do not overclock it unless shooting for 4Ghz or above] increase vcore to 1.45 and keep reducing it by a factor of 0.250V until you find the lowest vcore for a stable overclock make sure you have a good CPU cooler and a 80 Plus rated power supply and your Motherboard should support 140 Watt processors if you wanna overclock Phenom II's
