It isnt really a matter of how long youv been doing computer, more or less a matter of how well you understand overclocking. Gotta know about multipliers,fsb and voltages. your clock speed = multiplier*fsb. and usually when you up the fsb, ya sometimes gotta increase the ram voltage, and when you increase the cpu clock speed, ya gotta increase the cpu voltage. Just use common sense when you do it. everyone has there own way of doing it.. the way i do it... i slowly increase the fsb a few mhz each time, and in between, i do a burn in test to make sure its stable. I try to knock back the multiplier to keep the cpu around the default speed while doing this.. Once the fsb is as high as i can get it without crashing, i increase the ram voltage a little bit and try increaseing the fsb more. Once it crashes after youv done a voltage increase, back the fsb off a lil and you got your fsb.. The i slowly up the multiplier on the cpu until it fails the burn in tests, then i up the voltage a lil bit. And so on so on, when it is as high as it can go with a voltage increase, back it off like .5 and whamo there ya go, system is as fast as it will go.
But if you are gunna overclock, make sure you have a good heatsink on your cpu. Heat spreaders on the ram dont hurt, Heck, a better heatsink and fan on the northbridge dont hurt either.
