Your CPU runs at a clock speed the manufacturer sets based on what is stable and reliable across all types of systems and cooling configurations. This clock speed may or may not be the maximum speed that your particular chip is capable of running. Overclocking allows you to increase this clock speed beyond its factory set value and if done properly, provides a noticeable performance gain without spending money on new hardware.<\/span><\/p>\n

This guide covers what overclocking is, whether it is worth it for your configuration, and how to do it step by step on both Intel and AMD processors.<\/span><\/p>\n

What is Overclocking<\/h2>\n

Every CPU has a clock speed measured in GHz (gigahertz) for how fast it can perform one cycle per second. For example, if your CPU is running at 4.0 GHz your CPU will be able to perform four billion cycles per second. The manufacturer sets this speed to ensure reliability across systems with minimal cooling, average power delivery, and mainstream motherboards.<\/span><\/p>\n

Overclocking allows users to operate their processor at increased clock rates, above what they were designed for. In this way, processors are able to execute computationally intensive processes (such as video editing, rendering 3D graphics, or playing games) faster and with fewer interruptions.<\/span><\/p>\n

Overclocking is the practice of increasing the clock rate of a processor to make it function at a speed greater than its original design intent. The clock rate effectively controls how many tasks a processor can perform per second, so increasing that increases its capabilities in turn.<\/span><\/p>\n

Besides the CPU, you may be able to increase clock speeds of both your GPU and RAM. To do this for the RAM, the simplest method will be to enable XMP or EXPO in your BIOS. This will enable an XMP or EXPO profile which will cause the RAM to operate at its rated speed instead of operating at some much lower default value. Since these values were chosen and validated by the RAM’s manufacturer, you should find them to be completely safe and compatible with those same modules. It is recommended to try this before even attempting to overclock your CPU as many users have reported very significant increases in real world performance without adding any risk.<\/span><\/p>\n

Is overclocking worth it for your setup<\/h3>\n

Honestly, overclocking is less impactful than it was before. Current CPU models already boost aggressively out of the box. This leaves little room for manual overclocking. AMD’s 3D V-Cache chips such as the Ryzen 9800x3D deliver excellent gaming performance at stock and have limited manual overclocking support. Additionally, Intel\u2019s 13th & 14th generation chips already run near their thermal ceiling.<\/span><\/p>\n

There are many CPUs that don’t have much overclocking headroom, and unless you take your time and do it carefully, you can make your system unstable until you revert the changes. That said, there is often extra performance to be found, and for the right setup it can be genuinely worthwhile.<\/span><\/p>\n
