This processor can be overclocked to some degree without any extra cooling (assuming you have the stock or better cooler and decent airflow). The general approach is to enter the BIOS and lower the HTT, RAM, CPU & NB multipliers to their lowest settings then increase the bus speed until you wont boot. Then increase the multipliers back up and lower the bus speeds til it boots again and see if it's stable. You will probably need to increase the voltages to gain stability.

Watch the temperatures while overclocking: I would not want to exceed 75*C load on that CPU.

For a more detailed explanation, I would look at guides such as:

the cooler is the normal one which came with the computer i havnt changed anything apart from adding extra ram and a graphics card

im reading the link you gave me, im stuck on the part "which is the recommended voltage for your memory" i have 2 different types of ram, one pair is elite team and the other 2 is the manufacteres one what do i do here?

Use a utility like CPU-Z and go into the memory tab and check to see if all of them have the same rated voltage.

first learner.. try ClockGen . works gr8 for me   I have the same brisbane 4400+ w/ efore 9500gt. " zxzx what do you think of that program.." got it from cnet free downloads.

ClockGen/CPUCool works fine as long as the right PLL is selected. Although it doesn't give the best oc and starts only after windows...BIOS would be best.
