Overclocking is the term for increasing a component’s CPU (Central Processing Unit or computer hardware) to speed up its performance. Increasing the clock rate causes the component to run at a higher speed and perform more operations per second. Overclocking maximizes the speed and performance of your PC
beyond its factory setting.
Many gaming enthusiasts, for example, want to exceed the factory-set CPU speed to build a highly powerful gaming PC. Overclocking a CPU produces a more responsive computer and runs the hardware as fast as possible. However, not all CPUs can be overclocked. Standard CPUs can have locked multipliers that prevent people from performing CPU alterations to achieve overclocking. Certain CPUs with unlocked multipliers are specifically available for overclocking enthusiasts who want to assemble the fastest performing PC.
As increasing the CPU speeds up your computer, the CPU will also produce excess heat. The additional heat produced can cause damage your computer it’s not counteracted with proper cooling and extra care. Keep in mind modern computers and laptops have become so advanced and powerful that overclocking may not even produce noticeable results.
Overclocking works differently for all CPUs, but first you’ll want to make sure your system has proper and additional cooling. Standard CPUs manage heat with a factory heat sink and fan. An aftermarket heat sink can further mitigate the excessive heat created by overclocking while an enhanced fan can release the additional heat and increase air flow.
Water-cooling serves as an optimal and efficient cooling option. Water-based coolant absorbs the heat, and then the radiator pumps it out.
Once you’ve installed a cooling system, you’ll need to increase the clock rate in the computer’s BIOS (Basic Input/Output System).
Gradually increase the clock rate (or voltage) while checking the stability of your system and monitoring computer temperatures each time. Reduce it back to a stable level once it has reached an unstable level or maximum heat. Avoid overclocking all at once by a large amount.
