In fact I am not interested in activating windose xp or vista. The only thing i want to do is to overclock my system, in which the BIOS has no overclocking options (even ctrl+f1 does not work) and i can not even overclock my cpu by clockgen or any other tool. My question is: Is it possible after installing my mainboard's modded bios to overclock my CPU? In other words can i unlock my BIOS's overclocking options? My mainboard is MSI K9GAM2-FIH and i found a modded bios for it!(A7327AMS.140) Please help! At least show me a way to do so!
