That said, you did try to go up too high too fast. Start by trying to get your fsb up higher - that gives you the most gains, rather than upping the multiplier.
When you reach the limit of the fsb at one multiplier, one technique is to drop the multiplier DOWN and keep going on the fsb. That and messing around with the VCore (core voltage - more power going through = more stability - this is where you do need to be careful, unlike with just a plain overclock of the fsb/multiplier).
Overclocking is a lot of fun, but can be expensive if you want to get some massive gains. Takes a lot of research too. You'll learn a shitload about processors, ram, motherboards, silicone, pretty much everything. Just take it slow.

Although overclocking is generally safe, improperly overclocking can damage components, if you think there is no risk, you’re just kidding your self. if you take it nice and slow, with a good motherboard, RAM, cooling, etc, the risk is really low, however, in Chris H's case, his motherboard does not have the proper safety features, such as locking the PCI bus, or small increments for raising the FSB, Furthermore, he has an AMD xp 1800, with out physically altering the CPU itself, it can not have its multiplier changed from the standard 11.5. Going further to show the risk, by not having a method to lock the PCI bus to 33 MHz, by increasing the FSB to 166 MHz from 133 MHz (the smallest jump he can make) that increases the PCI bus to 41 MHz instead of the standard 33 MHz, in effect overclocking all device that resides on it, which is nearly all of them, so you are stressing everything beyond what they are designed for don’t forget that the AGP bus is on the PCI bus, and should be running at 66 MHz, but will be running at 82 MHz, if it is a 2x or 4x AGP slot, although the clock rate does not increase, the signals per clock do making a 4x AGP slot (my guess on what he has) would run effectively at 333 MHz instead of the standard effective rate of 266 MHz which can damage the card, theoretically, the system should halt before damage is caused, but safeties do fail. Further more, you are flat wrong about why overvolting increases stability, its not due to more power going through, it has to do with the speed it can change between the high and low voltage that the transistors are expecting.
Here is a wonderful thread about overvolting to expand your knowledge:

I’m not telling Chris H to never overclock, it’s a lot of fun, and as you said, and you learn a lot about the internals of a computer, however the system he wants to overclock is not overclockable.
