Help overclocking AMD 64 2800+

[markysparky]

There is unfortunately no overclocking options on my bios on my pc, however I have been thinking that maybe I can adjust the multiplier to overclock, I have a few questions though
*Firstly is the multiplier on the AMD 64 cpus locked
*Secondly if so then how can I unlock the multiplier
*Finally does anybody have any programs that they would recommend to adjust the multiplier

P.S. I have found a program that lets me adjust the multiplier but it seems I can only adjust it downwards

anybody know if the trick with the pencil works with these like it did with the previous and cpu's
