In this guide we will cover the following:

Overclocking is simply put, making parts of your computer go faster than they would by default. Overclocking is not always safe for your hardware, before attempting anything in this guide, make sure you have adequate cooling on the part of your pc that you will be overclocking (CPU or GPU).

The most commonly way used, and also the easiest and most foolproof method of overclocking ATI video cards, would be by using RadLinker.

The program is very easy to use, you simply use the sliders to adjust the clock speed of the core, and the memory. If you dont want to risk harming your hardware, i dont reccomend overclocking more than 25mhz for either the memory or core. If you want to take a risk, and you know you have adequate cooling, you could go up to, but no more than 50mhz over. If you have tons of cooling, such as watercooling or just a crapload of fans, you could possibly go over +50mhz if you arent getting artifacts before this point. If you start getting artifacts, STOP OVERCLOCKING AND LOWER THE CLOCK!!!!! Artifacts are a bad way of letting you know that the card is either oveheating, or damaged.

Coolbits is not really a program, but more of a registry hack, to unlock the overclocking feature hidden in the Nvidia drivers. Once downloaded and installed, you can right click on your desktop, go to properties. In that menu, go to the settings tab, and click advanced. Once in this window, click the tab at the top with your card name, and then on the left side, you should see clock and frequency settings, as seen in the screenshot below:

This operates much like radlinker, in that all you need to do is adjust the sliders to overclock. If you dont want to risk harming your hardware, i dont reccomend overclocking more than 25mhz for either the memory or core. If you want to take a risk, and you know you have adequate cooling, you could go up to, but no more than 50mhz over. If you have tons of cooling, such as watercooling or just a crapload of fans, you could possibly go over +50mhz if you arent getting artifacts before this point. If you start getting artifacts, STOP OVERCLOCKING AND LOWER THE CLOCK!!!!! Artifacts are a bad way of letting you know that the card is either oveheating, or damaged.

If your cpu is unlocked, and your bios support it, you can overclock your cpu through the bios. To access the bios, press either f2, del, f10, or f11 while your computer is posting on startup. the most common bios access keys are del and f2.

Once in the bios, you are going to look into the Advanced Chipset Features. In here, you can (sometimes) adjust the multiplier of your cpu, and the fsb. To overclock,

Adjust the fsb. Keep in mind that for ever 1mhz you overclock the fsb, it is multiplied by the cpu's multiplier. for instance, overclocking a cpu that runs at 2000mhz with a x15 multiplier, overclocking the default fsb (133 for the cpu in this example) by 1mhz, would make the cpu run at 2015mhz. Keep mind of the cooling requirements, if you do not have adequate cooling, you should NOT try to overclock. Also, the PSU comes into account when overclocking he cpu. a 350watt should be enough to overclock around 200mhz, but if you plan to go higher, i would reccommend a 400watt or higher.

Speedfan is a very useful program that can tell you temperatures, fan speeds, and plenty of other information about your computer. One of its other uses, is it can be used to overclock the cpu while in windows. It is done the same way as through the bios, by adjusting the fsb, the only difference is that it is doable through windows.

While in speedfan, select the tab at the top labeled "clock". from here, select your motherboard make and model at the top. to overclock, click an fsb down at the bottom, and hit set clock. be cautios about overclocking by large amounts through speedfan, as windows may become unstable.

Clockgen is another really simple overclocking tool to use. Whether or not you can use it depends whether or not a compatible PLL is detected. If it is, great, you can overclock, if not, well you wont be able to overclock with clockgen.

Overclocking through it is really very simple, just drag the appropriate sliders to clocks you see fit (though not too high or the system will become unstable) and hit apply, and POOF! youve just overclocked your cpu.
