Overclocking the AMD Athlon XP 2500+

I have an AMD Athlon XP 2500+ (1.83 Ghz)
My system specifications are as follows:

Athlon XP 2500+ (1.83Ghz)
AOpen AK77-8XN Motherboard (1Mhz stepping for Overclocking)
40 GB HDD Seagate Barracuda @ 7200
1 GB Simpletech DDR Memory @333Mhz
Gainward Geforce4-Ti4600 128MB

................................
I want to overclock my Barton 2500+
and dont know how to.
I am using the conventinal cooling solution that came with the Barton Processor.
Now if i want to overclock do i need a good fan. Can u advice which fan can be good for overclocking the Barton 2500+.
AND how much can I overclock it.
I am running the Barton at the standard 1.83 Ghz.
I want it in the range of 2.2 GHz or above. As upgrading to 3200+ doesn't make sense if i can make the 2500+ to overclock and look like a 3200+... please advice.


~AMD=RULES~

Read newbie guide to overclocking first. But yes manuhard is right.. you will want ddr400 memory with good low timings for a solid oc to 3200 speeds(2.2ghz)

For cooling it depends if that's as far as you want to go or not.
Thermalright heatsinks are amazing, but also costly.
As well you will most likely want to purchase a nice airflow case.
Although i'm pissed at antec the super lanboy is a good setup for cooling. I'm not recommending it just showing examples.
You will also want a good psu.
