|Overclocking an OEM computer is generally a bad idea. Overclocking means more heat and higher power consumption and OEM systems have little tolerance for either. Manufacturers are well aware of this and usually leave out of the BIOS the settings necessary for overclocking. This saves you from failures and them from the resulting warranty claims.|
Overclocking is best done with home-built systems where you can control the quality ans specifications of the components used.
