    Don't Jump the pool yet. Check out the following points to know if ur Sys meets the Overclocking Requirements:-

    The Motherboard

    The quality of the motherboard is crucial for successful overclocking! Due to the fact that the CPU produces fewer 'clean' signals in overclocked mode, reflections and other flaws on the bus can cause the system to crash or hang. The reverse situation is also true - in overclocked mode the CPU is more sensitive to unstable signals from the bus and will crash if the motherboard can't deliver clean signals. Always go for a branded motherboard!

    You will have to decide if you want to go for a higher bus speed or if you will stick to a maximum of 66 MHz.

    The board should obviously support a wide range of CPU supply voltages. Minimum are 3.3 and 3.45 V, for STD and VRE voltage. If you want to use P55C, M2 (the new M1/6x86), or the new K5/K6 CPUs, you will need support for 'split voltage'. This means that the core of the CPU requires a lower supply voltage than the I/O ports of the CPU. The latest boards all support 2.5 up to 2.9 V in 0.1 Volt steps. If the board offers you an even higher voltage than 3.45 as well, you should be happy, because this might be the last trick to get your CPU successfully overclocked.

    The RAM

    This topic is not new, but it is very important indeed. You will have to consider decent RAM if you want to run your system at bus speeds of more than 66 MHz. If you want to run an HX board, such as the Asus P/I-P55T2P4 at 83 MHz bus speed, you will require high-end EDO. I've experienced myself, that the marking of the RAM is less important than it's brand. Be careful, however, that you don't get second-rate chips from the manufacturers being sold in some stores. These chips still say Siemens, Micron, or whatever on them, but their quality won't live up to your expectations. In the case of high bus speeds always go for SDRAM if you can. SDRAM relieves a lot of the worries of running at 75 or especially 83 MHz, and runs flawlessly in any case.

    The Cooling

    My opinion is that you should go for a heat sink, and most importantly THINK BIG !! If a big heat sink still can't do the job, add a fan on top of it. If you achieve this cooling effect, you can be sure that any crashes which do occur are not a result of overheating. So how to get a decent heat sink ? Don't even think of finding anything in a normal computer shop. You'll find professional heat sinks only in professional shops which sell electronic equipment such as transistors, resistors, chips, etc. (e.g. Hobby Electronic Stores).

    You can tell how good a heat sink is by looking at the K/W value. K/W means degree Kelvin per Watt of power dissipation . K/W tells how hot the heat sink gets per each Watt of heating power of the device it's meant to cool. If you were able to follow that, you will understand that the smaller the value, the better the heat sink. If you can get a heat sink which has a value below 1K/W, you've found a good one. You'll need to make the surface of the heat sink that will attach to the top of the CPU match the size of your CPU (maybe the electronic shop will cut it for you, otherwise you'll have to do some sawing and grinding). Be careful that this surface stays completely flat, so that there are no gaps between the heat sink and the CPU surface. Finally, you only need to affix the heat sink to the CPU which is best done with some thermal compound (also available in every electronic shop). You can also use super glue, but it should be applied very sparingly with just enough to attach the heat sink. Do realize that you might not be able to remove the CPU from the heat sink if the super glue is good stuff. If required, attach a good (powerful + quiet) fan to the top of the heat sink (how, I will leave this up to your imagination).

    You should also use besides these hardware solutions some software solutions like Rain , Waterfall or CPU Idle. These utilities execute halt instruction during the idle priority thread and thus keeping the CPU cool. I recommend use of Waterfall because of small footprint, no VXD's, no drain of any system resources and above all it's free.

    Check In BIOS you should go into power management or voltage control and up the cpu frequency and you FSB (Front Side Bus) but becarefull overclocking can cause it to over heat alot faster and you might crack the CPU so dont amp it to high above the default level

    don't.... overclocking is harmful.... it's risk there may damage your PC
