"As I'm sure you are aware, overclocking is making the CPU run at a higher speed than the default. I am not a fan of this practice for several reasons. The first is that overclocking the CPU voids the manufacturer's warranty, thereby putting the system at risk if it were to fail. Another reason is that the price of CPUs has come down to a point where you can simply purchase faster CPUs for the systems and applications which would benefit from them. The last reason I do not believe in overclocking is that it increases the temperature of the CPU and requires more cooling, which is one of the more expensive costs related to maintaining a data center. This offsets any advantage you would realize from overclocking the CPU to save some money."
