hey ...

now that my 6400 finally got here ...
ive decided to try and speed up my old system.

Its a 433 celeron on an ASUS p2b-f (440 bx)

I guess what I'm goin to start with is :-
1. up the fsb to 100

Question : do i need extra cooling for this ? or can i just change the jumpers and let it go ?

thanks chosenfool ...

ok ... i'll be sure to get extra cooling then ..

lets see what this baby can do ...

You might want to add another case fan too. It will make things easier on your CPU fan.
Remember that you might have to bump up the voltage on your CPU, don't go up very far and remember that it generates extra heat.

What evilcyclops said was absolutely on the ball. You'll probably want to up your voltage by .05 or .1 volts. Doing this usually makes overclocked chips run more stable with a tradeoff of producing even more extra heat than just overclocking alone. The default voltage for a 433 celeron is probably 2.0 volts, so if your system seems unstable, bump the voltage up to 2.05 or 2.1 volts, if it is still unstable, you could possibly go as high as 2.2 volts, but don't go any higher than that, and hope that you don't have to go that high. If it still isn't stable at that voltage, first, make sure it's getting cooled enough, and then finally, if it still isn't stable, you're probably out of luck.
If everything goes well, leave the system at that higher voltage for good amount of time. This amount of time varies depending on how much your system is turned on and how much you use it. If your system is turned on 24-7, and you use it frequently, after a month or two you should be able to try lowering the voltage back down towards the default (2 volts in this case)(less useage means more time before lowering voltage). You may need to do this in steps, such as going from 2.1 to 2.05 and leaving it for a while. What you've effectively done is to do what is reffered to as "burning in" a processor. It's a phenomenon that helps a processor "get used" to running at a higher speed than it was intended to.
Oh, one final note, make sure to get an extra case fan or two, your processor is going to be dumping quite a bit of heat into the case, and its a good idea to get that extra heat outside your case.
Hope this helps,
