Of course, it can speed up the system some, but it has the potential to do damage to the system. It should not be done especially on systems that are very important in your daily operation. If you use your computer for work or have important data on it, do not overclock. I would never overclock a system I really need. The Overclocking Basics Quite simply, overclocking is changing the settings on your hardware to make it run faster than the manufacturer intended.
All hardware has a certain margin of speed that it was designed to run in.
The thing is, much of this hardware CAN run faster than it is rated for. Probably because the manufacturer wants to be able to guarantee that their processor will run at some speed. So, they choose a setting that ALL of them can do. For this reason, you can sometimes run into problems. These jumpers control the bus speed and the processor speed.
