Processor speed is determined by two factors, namely, Front Side Bus (FSB) and multiplier factor (multiplier factor). Second factor is the variable in the processor clock
Processor Clock multiplier x FSB = Factor
processor that has been in the launch in the market do have a speed
specific. However, this speed control will surely be at the hands of the motherboard. The motherboard has the right to determine their own value speed processor. Most motherboards are now circulating that would give rights to the hands of users (read: the overclockers).
As a result, the user can manipulate the speed of the processor in the following manner:
Increasing the FSB (also improve the entire system bus)
with the increase Front Side Bus (FSB) speed of the processor automatically will increases also. Usually this can be done by changing the settings change the configuration through the FSB jumpers on the board. On the mother board, a more modern, FSB can be changed through the BIOS setup.
Increasing the FSB resulted in the PCI bus, AGP speed and RAM automatically will also increase. When the PCI bus speed is too high, all the peripherals connected to the PCI and IDE will disrupted work. This usually brings the most influence on the hard disk (hard disk also includes PCI peripherals). Increasing the speed of the AGP will stabile the graphic card is used. However, sometimes it is deliberately done in order to obtain better performance from AGP peripherals.
In general, RAM to work with the same speed with the FSB (except on the board with the latest chipset) therefore, automatically increase the FSB also means to overclock the RAM used. It’s possible the motherboard and processor can work with a high FSB, but if the RAM is used not able Go, the system will hang or become unstable.
The increase factor (multiplier Factor)
No to all processors, but safe for other peripherals
One way that this can only be done with a processor that is still using the socket 7, AMD Athlon AMD K7 and K8. while intel, pentium II, since the launch, already do key value to this factor (multiplier) so that the business is only limited to overclock FSB only.
The advantage of this method lies in the not subject to AGP and PCI bus left the FSB remains at normal speed.Raising both (depends of the ability of the motherboard)
The combination of the two previous methods can be done to obtain greater performance again. Typically, this method begins with the increasing multiplier value. After that, the FSB speed increased gradually. This is done to make your clock to find the maximum and the maximum FSB your system.
In general, the FSB and multiplier can be adjusted via the motherboard. Thus, the ability of a processor depends on the ability of the board in the FSB and multiplier to provide the necessary. The motherboard provides a variety of options will FSB and multiplier, means the better the motherboard’s overclocking capability.

Note that the default processor speed is 1800MHz which is 200MHz (FSB) * 9.0 (multiplier) = 1800MHz
Then we will improve the speed of the processor is to add value with a 250MHz FSB speed so the processor will be 250 * 9.0 = 2250MHz

With this ability that has been in the computer overclock on the increase and the process can dilakuakan more quickly. As a consequence the temperature of the computer itself will be increased. Note the picture:
This is the temperature before the overclock
Temperature after the overclock
Can be seen in temperature before and after the overclock one degree centigrade rise
And speed of cooling fan cycles participated also increased, this is so because the resulting temperature is not too high so that the system performance
The increase in processor speed can be improved not only via BIOS only. Some of the motherboard that provides the features Overclocking on sales package will provide a special program so that the computer overclock overclock can be done via the desktop.
Before the overclock
After the overclock
If a system malfunction or system is not able to shoulder the burden so that hangs in the process of overclocking one solution is to reset the CMOS BIOS to its original position in a way to change jumpers on the motherboard. Or with the utility facilities in the motherboard provided by producers themselves.
