Concept of Overclocking
The process of running the computer system at higher clock speed than their original speed is termed as Overclocking. (E.g. a CPU is running at a speed of 1.4GHz which is supposed to work at 1.2GHz or 200MHz CPU at 233MHz). Core i7 have some significant components which needs further improvement in traditional processor’s overclocking.

Focus and Manipulation
Most of the regular user buys low speed computer components and they overclock to higher speeds. They mainly focus their efforts on computer components like Processor, Chipsets, Motherboards,  Video cards and Random Access  Memory (RAM) during the clocking. But to be more concentrated, Manipulation on the motherboard front side of bus and especially on the CPU’s multiplier is done for major overclocking to impact. It is done till it reaches the required frequency. It can be done by replacing the Front Side Bus with the QPI (Quick Path Interconnect) because Intel Core i7 have its maximum use & often this is called the Base clock (BCLK).  Also overclocking in Core i7 is much affected by CPU multipliers, bus dividers, voltages, thermal loads & cooling technology.

Overclocking Consideration for Core i7:

1. The clock rate should be having the low speed than the CPU’s speed.
2. Ensure that component should supplied with proper power supply
3. Excess power can also damage the component.
4. Perfection in tolerance is must.
5. Expensive mother boards need advanced settings that computer enthusiasts are likely to use that will also have built-in overclocking capabilities.

Advantages
Due to overclocking there is faster access of the data on the hard disk.
On the cheaper component we can increase the speed.
Overclocking itself is an engaging body and supports dedicated online communities.

Some bottleneck system where overclocking of component carries full potential than the limiting hardware is overclocked.
Improved performance in Gaming, Encoding, Editing with no additional expenses. Overclocking can increase the time before upgrade is needed.

Overclocking increase the speed of the Core i7 system significantly. Cooling techniques can reduce damage due to overheating. Even the graphics cards can be also clocked .The other option to clocking is flashing and unlocking to video cards. It has to be noticed that Core i7 have not only introduced new technologies like Turbo boosting and Quick Path, But also have totally new Nehalem microarchitecture, these factors will lead to serious changes in traditional overclocking techniques.

So folks, take proper precautions before overclocking this Nehalem Based Processor.
