A15.) Overclocking is the process of forcing a computer component to run at a higher clock rate than it was designed for or was designated by the manufacturer, usually practiced by personal computer enthusiasts in order to increase the performance of their computers. Some of them purchase low-end computer components which they then overclock to higher speeds, or overclock high-end components to attain levels of performance beyond the default factory settings. Others overclock outdated components to keep pace with new system requirements, rather than purchasing new hardware products as expected by the computer industry.
Users who overclock their components mainly focus their efforts on processors, video cards, motherboard chipsets, and Random Access Memory (RAM). It is done through manipulating the CPU multiplier and the motherboard's front side bus (FSB) speed until a maximum stable operating frequency is reached. While the idea is simple, variation in the electrical and physical characteristics of computing systems complicates the process. CPU multipliers, bus dividers, voltages, thermal loads, cooling techniques and several other factors can affect it.
