AGNGA is a new stepping, the original XP's were AGKGA's. Hmm... Newer steppings, usually mean better yields which in turn usually means better overclocking results! =) And on that topic, this little brown chip seemed to clock pretty high! Starting at 1.6 GHz, it went up to 1.8 GHz no problem! Any higher and system stability was a problem. Of course, since AMD is reaching the limit to clock frequencies on the .18 micron manufacturing process, you won't see 50% increases until the Thoroughbred core comes out later in Q1'02. That core will use a 0.13 micron process.
