Consideration

There are several considerations when overclocking. Overclocking boosts the performance of a computer system by increasing clock frequencies, which requires certain precautions. The first consideration is to ensure that it is supplied with adequate power to operate at the new speed. However, supplying the power with improper settings or applying excessive voltage can permanently damage a component. Since tight tolerances are required for overclocking, only more expensive motherboards—with advanced settings that computer enthusiasts are likely to use—have built-in overclocking capabilities. Motherboards with fewer settings, such as those found in OEM systems, lack such features in order to eliminate the possibility of misconfiguration on behalf of an inept user and cut down on the support costs and warranty claims to the manufacturer.(en.wikipedia.org/wiki/Overclocking)
