Overclocking is the process of increasing the frequency of the computer components over stocking regimes with the aim of increasing the performance.
Increased frequency may reach a maximum value, which is that when the system remains stable in the required user mode. In most cases, during overclocking, the heat dissipation of the concerned component, as well as power consumption, and noise, increase.
Sometimes there are degradation processes in the hardware.
Use free sample research on the topic to learn that the term overclocking is originally an English word composed of over and clocking derived from the verb to clock that is understandable as clocking. So, overclocking means literally a technique of going above stock clocking of processor. As well many terms in the computer world, the term is internationally accepted and is usually not translated. There were some attempts, but the original English term is predominantly utilized all over the Globe.
The ultimate goal of overclocking is to increase the performance of the hardware. The side effects may include increased noise and heat dissipation, instability of the overclocked components, particularly if there is non-compliance with rules, which imply the increased cooling equipment, redundant power supply unit, fine tuning of the overclocked components.
The opposite goal is pursued by underclocking, which seeks to reduce the frequency of the equipment (and, sometimes, the required voltage lowering) in order to reduce heat, noise, and sometimes instability. This type of hardware modification may be particularly relevant for working in some quiet space, saving energy or battery-life prolongation.
The components subjected to overclocking usually are CPU, memory, graphic cards, motherboards, routers, and even some monitors.
The classical method of overclocking can be the hardware low-level setting adjustments through the BIOS, implying the stock frequencies changing of the system components.
Another alternative is the BIOS firmware flashing, which has already been modified and has other settings of default voltage and frequency. The third method is to increase the component frequencies via the operating system by using a special booster software.
To improve cooling and reduce noise, liquid cooling systems, more efficient and having better noise characteristics are to replace stock coolers, and more effective thermal grease is used.
To check the stability of an overclocked system, a special software is used, monitoring the stability at the maximum load mode. To test for stability, classically, such software as Prime95, Everest, Super PI, LINPAC, SiSoft Sandra, BOINC, Memtest86+, OCCT are used.
The main risk of overclocking is to destroy the processor by application of too high voltage and, as consequence, having too high temperature at the core level, or electric surge. In the past, processors were likely to be burned if the temperature becomes too high, but currently all processors are equipped with a sensor system that automatically cuts the system if thetemperature exceeds the limits set by the manufacturer (automatic cut-off on the C2D and C2Q at 120/125 ° C).
