OK, well, i'm i've seen many threads about overclocking since i have been here. Now i want to learn.

I have a AMD 4200+ with stock fan, is this overclockable?

If so, what do i need to know about OCing, what things do i need on my PC???

Even if i can't OC my CPU, i still want to learn
 
Before you attempt overclocking the CPU, you really should know what you are doing. Any CPU is overclockable, as long as the motherboard allows it. Overclocking usually means changing the FSB, or in some cases the multiplier but usually not. When you change your FSB sometimes you will have to change the voltage as well, but you never want to much voltage, or too little. This leads to a lot of stress testing and trial and error with the CPU. Is your computer a custom or manufacturer build? because a lot of the time with manufacturer computers the settings on the BIOS are locked, which allow you to overclock. You say you have a stock cooler, and that's okay, but you won't be able to OC as much as with a higher end cooler. Next time you boot your computer up trying pressing delete, or whatever button on your keyboard that allows you to access the BIOS and look for frequency/voltage control or something like that in the menu.

Read up on some of these guides first:

OK, well my motherboard is a Asus M2N X SE, when i reboot my PC / boot it up next time, i will have a look at the bios, also my PC is a custom build!

More details about my computer can be found here, there is also a link to details about my motherboard on the page
 
Umm... I assume your PC is custom built? Well you need to go to BIOS, and raise the system bus frequency, lower HT link multiplier (HT Link is at @1000 (x5) by default, going beyond that causes instability really fast, lower the multiplier to x4), and that's the basic stuff.

In addition, you may need to do some playing around with memory speeds&timings, if you can unlock the speeds (run RAM out-of-sync, not sure how this goes with AMD), you may need to do that. Not for performance reasons, but just for now to eliminate the possibility of memory interfering with your OC, so you can figure out how far you can push your CPU. After you're happy with your CPU OC, you can start playing around with memory speeds&timings.
 
unless its a black edition/fx processors for amd or extreme edition by intel, you have to oc by fsb(front side bus), but i have no real idea of how to actully do that :S

oh great, so does that mean, i can't do it?

No. Did you read my previous post? The HT Link is somewhat analoguous to FSB, both CPU and HT/FSB speeds are all dictated by the system bus. Rising the system bus frequency increases the CPU frequency, as well as FSB frequency (in case of intel rigs) or HT Link frequency (in case of AMDs).

However, you can't really OC the HT link. If the HT link speed goes beyond 1000MHz, it's not going to take it well. That's why you need to lower the HT Link multiplier.
 
If you want to be on the safe side. Dont know what speed memory your running but if you have DDR2 800 bump it back to 677 or if you have 677 bump it back to 533, you get my drift. Then set your Hypertransport from X5 to X4. Then start raising your Bus speed from 200 up a couple of mhz. at a time. When you finally get to the point it starts getting unstable either bump up your CPU voltage or back off the Bus.
