Best stable OC'ing of the Asus P4S533

[Marc]

What is best level for this board with a 1.6a and how do I get it there?

I currently have it running at 2133, with just jumperfee bios settings, is there more I can get out of it and still have it be stable?

I'm a newbie, and don't really know how and what to adjust.
