I have recently purchased 2 p2 x4 920 from newegg for 2 new systems, and interestedly found them to have 2 different stepping codes, one is 0901APMW, the other one is 0851CPEW, can anyone help me decode them?
First letter is the production/release code if this was an ES chip it would be an A. They are using the letter C for current production release chips although they don't always use C
2nd letter is the Core Cache code It will probably be different with lets say X3chips and X2's with less cache
3rd and 4th letter identify the memory controller revision. This apparently is a CV revision memory controller.
5th letter is usually a revision code
C = Deneb most likely in this case......
Next we move onto the 4 digit number code......
year and week
Now the last 4 has always been vague but i've always believed them to be the code that determined who tested, time of day, etc etc.....I really don't think its as pertinent unless the guy testing was half in the bag (not likely)
