Hey! In this article I want to share some of my experience and knowledge. It`s about overclocking. Maybe this one doesn`t suitable for expert or enthusiast overclocker, it is just the basic of overclocking for anyone who wants to try overclocking. Shall we begin?
Ok. What is overclocking. Overclocking is a method to get more performance from a system as much as possible. How could it be possible? It`s possible because most of hardware today has a safety margin, so that hardware can be” pushed” to perform exceed the manufacture`s spec. For simple example AMD 3000+ normally runs at 1,8Ghz, but I can make it runs at 2,0Ghz without any problems , even I don`t have to change my CPU cooler but I gain more performance.
How to do it? I will explain the basics. There are some components can be overclocked: CPU, RAM, Motherboard, VGA Card. For this article I will just explain how to overclock CPU. The other components I will explain in separate articles.
There are some setting can be changed to increase the performance of CPU, they are FSB, Multiplier and VCore. The first one is FSB (Front Side Bus) will control the speed of the CPU. And together with multiplier , they are going to determine the clock of the CPU. For example my AMD 3000 has FSB 200MHz and multiplier = 9. So the CPU clock is 9 X 200Mhz = 1,8Ghz. Simple huh?
To increase the CPU speed you can change either the FSB or the multiplier. For example you can change the FSB from 200 to 220. So you get your CPU speed = 9 X 220 = 1,98 GHz. Or you can change your CPU`s Multiplier, but most of CPUs have their multiplier locked, so you can`t change the value of your multiplier. But some CPUs allow you to change their multiplier (AMD X2 5000+ Black Edition for example). For Example you changed the multiplier from 9 to 10 with FSB 200MHz. Your CPU`s speed will be 10 X 200 = 2.0Ghz. Or you can also lower your multiplier, from 9 to 8 for example, and your CPU will run on lower speed.
The other setting you can adjust is vCore. This the most “dangerous” part, because if you adjust the vCore too high, you can fry your CPU!!! Ah btw, vCore is the voltage supplied by motherboard to CPU. So Why do you adjust vCore? You adjust it as you overclock your CPU, your CPU needs more “supply” to keep the system stable. And remember, as you increase your CPU speed and vCore, the more heat you will have. So you have to keep your CPU cool to keep your system stable. You can change your manufacture cooler into aftermarket cooler with heatsink that will cool your CPU better. Or you can change your cooler with water cooling system and there are many other ways to keep CPU cool.
