Over clocking a computer is through the ways of man-made CPU, graphics cards and other hardware to improve the operating frequency so that they are rated higher than the frequency of its stable state.

First of all, what is the speed of CPU?

For example, Pentium 4 3.2GHz CPU running at 3200MHz under. This is a measure that how many clock cycle processors experienced. One clock cycle is a period of time, during this period of time the processor to perform a given number of instructions. Therefore, logically, the processor can be completed in the second clock cycle, the more it can process information faster, and the system will run faster. 1MHz is one million clock cycles per second, so a 3.2GHz processor can be experienced at 3,200,000,000 per second or 3 billion 200 million clock cycles.

The purpose of over clocking is to raise levels GHz processor so that it can be experienced more per clock cycle. For example, Intel P4C 2.4GHz,it’s rated operating frequency is 2.4GHz, if the operating frequency up to 2.6GHz, the system can still operate stably, over clock successful.

CPU over clocking is to increase the working frequency of CPU, For example, a CPU FSB to 100MHz, multiplier of 8.5, can be calculated by its frequency × frequency = FSB = 100MHz × 8.5 = 850MHz.

CPU can be upgraded by changing the frequency of the CPU multiplier or FSB. However, if you are using Intel CPU, you can ignore the frequency, because Intel CPU used a special manufacturing process to prevent modified frequency. AMD’s CPU multiplier can be modified, but Modified frequency to

Upgrade cpu performance not as good as FSB.

The FSB speed usually associated with front side bus, memory speed links. So when you upgrade after the CPU FSB, CPU, and memory system performance has also improved.
