NokiaXP: Just read the second post, after "Yes" and see what it says.
You ask questions that have been answered many, many times, I think you should start using the search feature. because all of the posts I've seen you post could easily be answered if you'd just use it.
Anyway, unless you want to unlock you can only overclock, any AthlonXP (Palomino, the t-breds are unlocked) you will have to use the FSB, because you can't change the multiplies on the XP. so if you're only planning on the system, get a board that supports 1/5 divider and get high quality ram and components
