There you have it
Here are the details:
AthlonXP 1600+ Palomino core
Green substrate
Stepping AROIA-Y
Week 13 2002
This is in my watercooler. The chip is from newegg, and is a very close realative to the previous 2ghz 1600+ I was running.
This isn't stable unless it's running below 95F, which is achieved by the arctic weather ;). The other CPU will only do 2050 about with these temps.
