First steps into overclocking

Hi folks, brand new on the forum.
I have been running my Duron 1.1 at a bus speed of 110 to give 1.21GHz...nice speed "one point twenty one giga watts" ala back to the future.
Anyway, as I said only adjust bus speed and can go no further and be stable. What are my options to increase????
gigabyte ga7vax, pc2700 512Mb, 450w psu.

Any help or advice much appreciated.....
Ben.
P.S. athlon XP 2400+ or 2600+ purchased soon to go with my new build!!!!

Dear me...rookie error..posted in the intel forum..disregard!!!!!

Improve cooling and give the voltage a little bit of an increase. That system ought to run at about 112 to 115 FSB.

Make sure u keep it cool though.
