Overclocking is a way to improve the performance of a hardware unit (generally processor) by running it at higher frequencies than rated. Overclocking is a risky process and it does voids the warranty of the component whether it is a processor or RAM. If done wrong then you may also cause damage to the component and render it useless. Overclocking of CPU or processor is done generally though the motherboard BIOS, where you can either increase the FSB, Multiplier or both in some cases. For extreme overclocking you may have to increase the voltage of the component or processor to make it run at much higher frequencies. Overclocking does increase the temperature of the processor / CPU and you have to buy a good aftermarket cooler to keep the temperature in control.
Here in this post I am going to talk about Graphics Card Overclocking. In Graphics Card you can overclock both the GPU (Graphics Processing Unit) and the Memory. The process of overclocking a graphics card is way different from a CPU because to overclock a graphics card you need some special tools. These tools are known as Graphics Card Overclocking softwares or tools. These GPU overclocking tools run in Windows OS and from there you can overclock your graphics card GPU and memory by using the interactive GUI. Here I will provide you the list of best free graphics card overclocking tools to overclock your nvidia or AMD based graphics card. You can also checkout the best graphics card info tools to know the technical details of your graphics card.
