<< blue Core = Copper interconetcts(sp) in the Chip
Green Core = Aluminum
Blue is from Germany and Green is From Auston Texas
All Athlons above 1 gig should be blue core
Duron are from Auston
Don't mind my spelling I don't feel well

Just thought it should be known that has long since been proven to be false. Their are MANY different colored cires on both Duron's and Athlon's.
I've seen purple, blue, green, yellowish, beige, etc etc.
I've seen all of the above on Athlons and Duron's of varying clocks. Simply put the color of the die is nothing more then the polish that was used in the fabrication plant at that given time.
And die polish has been known to change on an almost weekly basis.
