Production Code?

post #1 of 6
Thread Starter 
Hey there. So after reading around I've noticed a lot of people mentioning CPU codes that are etched on to the CPU. How do you read these and what do they mean?

Eh, nice, but not exactly what I was looking for. Something about the lower numbers being better or something like that.

That doesn't really say much about the lower numbers. It's something about the lower numbers etched on the IHS being that of the number of the die. Lower number means the die is closer to the wafer, higher number means the die further to the out side of the wafer.

The problem I'm having is identifying which number set etched on to the IHS represents this. Anyone have any idea?

There is only one more set of numbers and it is the serial#.

Here's a few links discussing this http://hardforum.com/showthread.php?t=1575677 and http://www.sharkyforums.com/archive/.../t-262888.html

a couple of quotes from those links;

"Rafale
This whole theory that the chips at the center clock better is perfect nonsense. I work in the industry. I would agree the the dies at the very edge are more likely to have defects but the center ones are second worse for some of the manufacturing process steps. The best compromise would be to get the mid radius chips. "

"ditchmagnet
You will have the batch number on the box, and once a bunch of people buy these chips and makes lists of their OC results, then you can have a reference for good batch numbers. At this point its just luck of the draw."
