What says an Intel batch code ?

[Fritz_the_germ]

Yo guys,
I got offered an Intel cpu (980X). The batch code says:
"3003B320". The first letter "B" means the plant code. In my case Costa Rica but I don't know the rest of the digits.
Could anybody please translate all these digits above?

There's "A" chips from Costa Rica as wel so i doubt the letter means plant code. For 980X "3003" means its from week 03 in 2010.

Thank you for the information.
What do you mean by "A" Chips. Are they good or bad?

Chip with 3031A241 code for example. "A" as in its letter, but also from Costa Rica plant.
