Every computer chip has something called a clock speed. A clock speed is the speed at which a chip can process data. Whether it’s a memory, CPU, or graphics processor, it will have a rated speed.
Overclocking is basically running these chips at rates higher than their specifications to get more performance, and getting the full potential from your computer.
A good motherboard to use when overclocking the i7-8700K is the Asus Rog Maximus X Hero.

You may want to overclock because you want to boost your computer’s performance without handling extra costs. And to do that with an i7-8700K core, here are the things you’ll have to take into consideration: the voltage and the temperature.
For manual experimenting, you basically begin the overclocking process by setting the voltage and core multiplier to default values (or near). Then test your computer to make sure of the stability of performance and the temperature.
Gradually increase the multiplier until it becomes unstable or the temperature goes too high. After you begin experiencing instability or high levels of temperature, you can either revert the multiplier to the last stable setting or increase the voltage and push the multiplier up.
The i7-8700K core can be boosted to up to 5.0 GHz without any problems and even 5.1 GHz.
To facilitate overclocking, you should keep the quality of your CPU in check.
And don’t forget that the overclocking success highly depends on the motherboard that you use to support it. And according to it, various levels and presets are available, or you can manually adjust the voltages and experiment with the performance.
The steps to follow are as follows: Adjust your BIOS settings where your AI overclock tuner should be set to “Manual” and the CPU core ratio limit should be set to 50. Then you should increase your CPU core/cache voltage to 1.35 volts.
These simple steps allow you to overclock your i7-8700K from a simple 3.7 GHz to 5.0 GHz.
Now let’s go back to the two things we said we have to take into consideration.
When it comes to voltage, overclocking the i7-8700K could be quite a hard task as the more extensive the workload was, the more noticeably higher the voltages used were compared to other cores when you overclock them.
As to temperature though, the i7-8700K can handle overclocking (up to 4.8 GHz) exceptionally well, if you place it in a well-ventilated case.
