I've been toying with o'clocking my PII 450 and am trying to get a feel for what is all involved and what components are affected.

I understand how the FBS and multiplier work to get the MHz. I don't get what roll the voltage plays in all of this. How do you set it? How does it affect the FBS or MHz or anything else? What, if any, are the dangers of changing the voltage?

Also, I have an ASUS P2B-L motherboard, 100MHz bus, PC100 RAM, CL TNT AGP card. If I increase the bus speed, how does that affect the RAM and AGP card? Do I need to do something to counter the effects of the bus increase? I thought I read that you would need to set something to 2/3 bus speed. What is that something? Any help is greatly apprecitated. Thanks!
