Tip on Overclocking CPU

Overclocking your PC's system is not really recommended as it can void your warranty, but sometimes it can work for you if you need to push additional power out from your CPU. Here I have is some quick tip on overclocking CPU clock speed, but always bear in mind of the following guideline:

Always to keep the memory clock speeds within the rated frequency of the CPU.

The purpose of the above suggestion is to avoid data error. Different brands of processors provide different supports. For instance, Intel only allows overclocking of the CPU's bus speed.

(see example here to understand better...)

With a Core 2 Duo E8200 processor (2.66GHz running at 333MHz bus speed and a fixed 8x CPU multiplier) and a DDR2-800 memory, the maximum safe Front Side Bus (FSB) frequency that can be set is 400MHz, which is still within its specification. Alternatively, for a FSB base of 333MHz, the system's memory will run at only 667MHz. Therefore, on switching to 400MHz, the DDR2 memory will run at 800MHz. This will push the frequency to 3.2GHz (400MHz x 8).

The ultimate outcome is a 20% improvement in clock speeds! That will probably save you money without having to purchase a faster processor, yet getting ther power good enough for faster video transcoding and 3D rendering, etc.
