There are several methods that people have used to overclock their processors:

1. Crystal Oscillator - A crystal oscillator is a small electronic component that generates a steady clock signal, expressed in MHz or KHz (ex. 27.1432 MHz) or. By replacing the clock signal with one that generates a higher clock (ex. 29.7265 MHz), you would make your processor also run faster. Although still possible, this method is more awkward on modern motherboards, because of the high internal multipliers and numerous buses running at lower speeds (curse you, PCI!). This method is still useful on many game consoles and portable devices, however.

2. Adjusting Front Side Bus speed (jumpers) - The processor always runs at a multiple of the Front Side Bus (FSB) speed. By increasing the FSB speed, the internal speed of the processor would also be increased. For instance, if the FSB speed is at 66 Mhz, and the multiplier is 3, the processor runs at 200 MHz. If the FSB is increased to 100 MHz, the processor will run at 300 MHz. This method has been largely replaced by doing it in the BIOS, since after the Socket 7 era.

3. Adjusting CPU multipliers (jumpers) - Adjuisting the multipliers for the CPU was a slightly easier and more reliable way to overclock, since it did not stress any other components, such as PCI or ISA. If the FSB was at 66 MHz, and the multiplier was at 3, the processor would run at 200 MHz. If the multiplier was changed to 4.5, the processor would run at 300 MHz. Intel locked the multipliers on all their processors after the Socket 7 era.

4. Adjusting Front Side Bus speed (BIOS) - Starting with the Pentium II era, Intel processor were multiplier-locked. The only method to increase the processor speed was to increase the FSB speed. This could be done in the BIOS of many non-OEM (ASUS, Abit, Tyan, DFI, and not Gateway, HP, Dell, or Acer) motherboards. Although it stressed the other buses slightly doing so, the higher multipliers in processors made even a small increase in FSB speed a large boost in clock speed. This method is still commonly used today.

5. Adjusting CPU multipliers (BIOS) - AMD left their multipliers unlocked for a long period of time. Even when they began locking them, they left them in a way that was easily unlocked again. Jumpers on the motherboard were replaced with settings in the BIOS. This method is not common today, although AMD still has some unlocked CPUs, and even Intel has begun unlocking their high-end enthusiast (Extreme) chips again.

6. Adjusting Front Side Bus (software) - The FSB speed, along with the other buses, is controlled nowadays by a chip known as a PLL. The crystal oscillator still exists, but it primarily serves as a reference clock signal for the PLL. The PLL is more often controlled through the BIOS, but special programs running in Windows are also available. This method is the only overclocking option available for many OEM motherboards (though some may still not work through this method). You will first have to reboot you computer into the BIOS ( usually by pressing the Delete key during start up). go to the Frequency Voltage control menu, find the entry called CPU FSB Clock, and increase it by the smallest amount possible (2MHz is usually a reasonable increment). Don't get impatient and try for a large jump, you'll have only yourself to blame if you fry a very expensive chip. Finally, save the settings and reboot your PC. Be aware that increasing the speed of the front-side bus also increases the speed of your system RAM, which could prove the limiting factor.

There are many ways to overclock, and there are a lot of resources available on the internet. With that said, it is possible to overclock a device through utilities, possibly through human ingenuity, (for example, the pencil trick for computer motherboards) and much more.

What is the correct configuration management process to overclock my processor?

The correct configuration management process to overclock your processor is going into the BIOS settings, and increasing the power of the motherboard. This is the safest way as well to overclock.

What causes the processor and memory speed to overclock?

That condition occurs when the motherboard clock settings are not set properly for the processor.


Which switch increases speed of processor?

There is no such physical switch on common modern cpus that increases the speed of cpu. To increase cpu speed one has to overclock it. Overclocking depends on the cpu and the motherboard. It is generally not preferable to overclock as it reduces the life of cpu and the motherboard, and can even lead to complete destruction of either or both of the components in worst case.


You do not overclock but you play games what motherboard should you get?

If you are a heavy gamer, you should opt for a DDR3 ram supporting motherboard. Also, if you want a future ready machine, opt for a motherboard which has SLI orCrossfire support so that you can add a second GPU when your single one feels 'dated'.


How would you normally overclock the CPU?

First of all you need a AMD processor, them you need a motherboard to run such processor. Once you have that up and running, use the disk that comes with the motherboard. Run the utility to overclock but be cautious because the processor running faster overheats easily, as well as the rest of components. Make sure you have a good cooling system, with two or more three -wire fans.


Is there a way to add 5ghz compatibility to a computer that can't use it?

No. If your computer's motherboard cannot overclock and if you do not have enough power and cooling for overclocking, you won't be able to do it. At the worst, you will burn out your computer parts.


Will overclocking my GPU hurt my computer?

If done incorrectly, overclocking can only damage the part that you tried to overclock (resulting in a burned-out chip which will almost always require replacement) or prevent the computer from starting up (not enough power to start up the computer).

Can you overclock a Mac?

You can overclock it, bit you can't put a new board in. If it's one of the older Macs that used the motorola processors (g4, g5, etc), overclocking will require some soldering and other hardware mods. If it's an intel Mac, there are apps that will allow you to overclock.
