I'm purchased new desktop with Intel Core 2 Duo E8400 3Ghz. But it showing that the processor is clocked at 1.8Ghz, i'm trying to overclock it. but in BIOS the overclocking option is not showing on BIOS. So what to do now. My MotherBoard is Aver-Tek G31 LGA775. BIOS version is 6.00 PG. I'm from India. And i have tried other software also like intel cpu configuration or some other overclocking softwares non of that are worked. Waste of time.
