In addition to the data transfer rate, the clock speed is one of the most crucial units for measuring how fast a CPU completes the computing process needed to process data. This clock speed is usually determined by the manufacturer and indicated in the CPU’s product specification. However, in most cases, the value does not represent the processor’s maximum performance capacity. Rather, the indicated speed meets the demands of most users, while at the same time enabling optimal energy-efficiency and the best lifespan for the CPU.
But what happens if the CPU’s clock speed is inadequate for your computing needs? This can happen, for example, if you use high-performance programs and raw data formats for editing photos and videos, or if you are a passionate gamer. Instead of considering a replacement of your CPU, you can manually increase the CPU’s clock speed in order to improve processing power. This is called overclocking the processor. The overclocking designation came about because the clock speed that was originally indicated is deliberately exceeded.
It’s also worth mentioning that overlocking is not only possible with the CPU, but with all PC components that operate with a periodical clock signal. That is to say, for example, a video card or RAM. If you operate all hardware components in-sync with a higher clock speed, you can increase your PC’s system performance considerably.
