I want to overclock intel core 2 duo e7200 2.53 ghz processor. My motherboard is xfx mg 63mi 7109 GeForce 7100 nForce 630i. Im having problem with it because my bios dosnt gives option of multiplier,voltage and other settings which are necessary for overclocking my processor. I have updated my bios, still no overclocking options. Currently my bios is American Megatrends 1985-2005. I want at least 3ghz speed.
