Amd steppings and what they mean.........

Here's AMD's explanation of date codes. It's still a mystery to me.

makes sense. i know it has been posted earlier. also does anyone have any info on how the cpu dies are numbered on the wafer? many say that they are numbered from the middle outward so if you get a 0001 chip then you got the middle of the wafer. this doesn't really make sense and i have heard that they just number it normally from the top left corner left to right.

I only read the first post.

I graphically compiled a small amount of FX chips for you all to investigate.

They're mostly review samples so they have the same week, 5 and 4-letter codes so it probably doesn't help much. To be honest, finding a good clocker is probably just a matter of getting lucky.

yea thats what i think too. the batch number isn't affecting anything and same with the steppings.

These are all xPMW CPUs. The P and the W are always the same because these CPUs made in Germany (Dresden). The M letter is always a good sign. For example the MPMW stepping always signs good OCing modell.
