The practice known as overclocking (formerly known as undertiming) aims to achieve a higher clock speed for an electronic component (above the manufacturer’s specifications).Overclock is an anglicism of habitual use in computing and pc components this practice was popularized in recent times, since it is not worth losing the component for winning a few few mghz. Overclocking is now more advanced and allows you to force the components even more (often nearly double) without that pass nothing, provided that they have good cooling. This increase in speed produces a greater energy expenditure, and therefore a greater production of residual heat in the electronic component. Heat can produce failures in the operation of the component, and must be combated with various cooling systems (by air with fans, by water or with a Peltier cell attached to a fan). Sometimes, failures caused by this practice, can damage permanently the component, other times, can produce a restart that entails the loss of data in open applications, or in some cases, the loss of the entire file system. Literally on the clock, i.e. increase the CPU frequency.
The idea is to get higher performance for free, or exceed the current performance quotas, although this can lead to a loss of stability or shorten the service life of the component. This practice is widespread among the most demanding computing users, trying to take to maximize the performance of your machines. Less daring consumers tend to buy low-cost computer components, forcing them later and thus reaching the performance expected by most high-end components. On the other hand, most fanatical consumers may acquire components of last batch to force its operation, and so achieve unattainable performance tests for any team of consumption. For this reason, most manufacturers choose not to include in your hardware warranty damage caused by overclockearlos. Today hardware manufacturers produce their unlocked to allow users to perform overclocked over them.
