first of all, do not overclock by straps (200, 266, 333, 400, 533). unless you're very familiar with your motherboard and processor then overclocking by straps is easy but something i wouldn't recommend since you don't have an idea yet.
start by manually setting the ideal voltages of your components (dili auto). set the processor according to VID. MCH or NB is 1.1 volts for P45, 1.5 volts for CPU PLL, 1.2 volts for CPU VTT or FSB Termination, 1.5 volts for SB. leave the memory voltage, frequency and latency and the CPU multiplier at stock. increase FSB by 5 or 10. after every increase do a 15-30 minutes Prime95 Small FFTs or OCCT Small Data Set stress test. The Small FFTs and Small Data Set stress test are tests exclusively for the processor only so any instability found is isolated to the processor only - di ka mamroblema sa uban components.
now, if mo fail gani after an increase at some point, increase CPU Vcore by 1 step and test again. continue increasing FSB and voltage and stop until you're no longer comfortable with the voltage (max = 1.55 volts for 65nm, 1.45 volts for 45nm) or you're hitting the extremes of your temperature. once you've reached the highest overclock of the processor, stress test for at least an hour. of course, more is better.
now that you know how high your processor can go at a specified voltage, you can move by trying to different combination. for example, kung imong overclock is 3.2 GHz (355 x 9), you can now try out different combinations by adjusting the CPU multiplier and increasing the front-side bus. 3.2 GHz can also be attained with 400 x 8.
at 400, i'm sure the CPU VTT voltage would require additional voltage pero start with what i'm telling you then let us know how high you can go so we can move on to the next step which is optimizing your overclock.
**EDIT**
start a thread about your overclock worklog para dali ra mag trace sa imong mga settings.
