I found this and thought you people here with Opteron Single and Dual core alike would find this interesting. This is not all of my own work so I cannot take full credit for this thread. The sources mentioned below deserve much credit. I felt one location of useful information would be beneficial.
The Following article contains information on the AMD Opteron 939 series
Please also take a moment to visit The Official Order of the Opteron
I now also Have an AM2+ thread for AM2 CPU submissions please visit

When submitting CPU OC info please include the following when possible

Now Lets tell you exactly what the Letters and numbers mean in a Stepping Code:
What do the letters mean?
For Example CCBBE
CCBBE
1st letter: "production/release code"
Pre-production or early samples have an "A" here where final production batches will be a "C" (for current chips). Some may recall that Venice samples where seen in the wild as "ABBLE" and current production runs are "LBBLE". While complete understanding of this is unknown at this time, it is clear that this has something to do with early samples.

While complete understanding of this is unknown at this time, it is clear that this has something to do with early samples.
CCBBE
2nd letter: "core cache code"
A = single core, 1MB
B = single core, 512KB
C = dual core, 1MB (each)
D = dual core, 512MB (each)
2nd letter: "core cache code"
A = single core, 1MB
B = single core, 512KB
C = dual core, 1MB (each)
D = dual core, 512MB (each)
Note: 'Toledo' cores (1MB) with half the cache disabled will still be coded as "C". Therefore, you can see earlie 4600+ samples as ACXXX with only 512KB per core enabled.
CCBBE
3rd and 4th letters/numbers: "memory controller revision"
Works like a counter using all letter of the alphabet and digits 1-9. 3rd letter increments when running though all available 'steppings' as noted by the 4th letter.

CCBBE
5th letter: "revision code"
C = rev C (as in CG Clawhammers)
D = rev D (as in D0 for CBBID chips....)
E = rev E (as in the rev E 'San Diego' core)
5th letter: "revision code"
C = rev C (as in CG Clawhammers)
D = rev D (as in D0 for CBBID chips....)
E = rev E (as in the rev E 'San Diego' core)
-FCG & s7e9h3n
0530, 0534, 0550, 0551, 0606, 0607, 0608, 1610 etc. etc. etc.
Simple,
the first 2 numbers (0610) are the year the CPU was made
the second 2 numbers (0610) are the week of that year that the CPU was produced (hence the highest it could ever be is 52)

MPMW, UPMW, VPMW, DPMW etc. etc.
These are some kind of packing code, it is beleived that the first letter (DPMW) has to do with the day the CPU was made, the details are still unknown.

Increasing the multiplier is unlikely to be the big problem in overclocking a
low-speed Opteron. Getting one capable of overclocking a lot will be. |

Trends are not absolute, no matter how much we may want to believe in them if they're favorable (or how much we may want to refute them, if not favorable). There is only one absolute law in the world of the dark art, and that is "Nothing is absolute." Theory and potential are one thing; results, observation, and reality are entirely different.  Hope this helps! |
I had to Quote this !
The Opteron 185 Dual core has been left out as i cant find the best stepping average for this CPU at current.
If people have New steppings to add for the Opteron 100 series both for Single and Dual core then send me a PM and ill add it with your average or maximum overclock and put your Username by it.
Hope this helps.
