AMD CPU numbers

[Phelios]

On the overclockers.co.uk website they have two Barton xp2500 cpus listed - (CP-039-AM) and (CP-040-AM) what do these mean? Also, i read a great article somewhere on how to understand the long numbering sequence/serial numbers on the Athlon cpus - does anyone know where to find this?
Thanks.

One is OEM, the other is Retail. So one is the chip, the other is the chip and Fan.

AMD Is An Anagram Of MAD, Intel Is An Anagram Of INLET, Cyrix...Ah Who Cares?
