AMD 64's are not like the older processers.
They really dont have a 'Front Side Bus' that you simply overclclock. The CPU actually has an integrated memory controller for itself, which is seperate from the ram. This is important because you dont want to mess up your config options in the bios.
Your 'FSB' say, times your HTT multiplier, should never be over 1K. that is why if you increase from 200, you need to put it down to 4x, from 5x.
Someone has a really nice guide for those of you new to overclocking it, I'm terrible at explaining, but dont just dive right in...
