What is Overclocking? Part I

The work speed of such components as processor, memory and some other ones depends on clock frequency and intervals set on your motherboard. You may make your system operate at higher or lower frequency by changing these parameters. Excess of working frequencies as compared to the values given by the producer of a device is called overclocking.

An overclocking is possible as the produces always leave a specific “safety reserve” for developing equipment which is need for its reliable operation during the entire service life.

Working frequencies for processors, memory chips and some other components are set with the help of a clock on the motherboard. These frequencies can be adjusted in BIOS, and overclocking is done by some easy changes of several parameters.

Before making s decision about overclocking, some problems may be encountered:

  • unstable computer operation, failures or hangs connected with higher frequencies of overclocked computers;
  • it is impossible to turn on the computer or to start an operating system because of too high working frequencies;
  • reduced service life of overclocked computers;
  • breakdowns of some computer components after overheating or too excessive supply voltages.


The responsibility and all the risks, connected with overclocking, are fully and totally borne by a user. Computer components damaged after overclocking are non-changeable.

So, there are the grounds against overclocking above, but a lot of users still overclock their computers. In doing so, they follow several aims:

  • to get the productive computer on a low price (in this case, saved money may be considered as a pay for the risk which may arise in future);
  • to reach desired productivity in one or several programs, mostly – in games;
  • to overclock the computer only for the sake of sport.

Based on the foregoing, you must weigh the pros and cons and to make an independent decision in every specific case.
