Overclocking a passion ... yes ...its also an art, fine balancing components via increasing FSB, SB, Volts in small increments and this can mean many hours of benchmarking, and can go something like (eat - sleep - overclock - eat - sleep - overclock

), Myself i have pushed components to there limit and it is exciting (a buzz), if you intend to try Overclocking >
1. Study and understand what you are about to do, preparation is important.
2. Patience is a main factor.
3. Don't Overclock what you can afford to replace.
4. Check your temperatures
A good quote > While pushing a system might start out problem-free, several months down the road when components have aged due to use and temperature changes, instability can crop up.
