Official Socket 939 Opteron Most Overclockable Stepping Averages + Info

post #1 of 68
Thread Starter 
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
Official Socket AM2/AM2+ Opteron Most Overclockable Stepping Averages + Info

When submitting CPU OC info please include the following when possible

1.CPU Used
2.CPU Stepping
3.V-core in use at current Overclock
4.Current Overclocked speed


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.

CCBBE
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)

-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

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.

A brief explanation:

1st letter= production release C is for current

2nd letter= A = single core, 1MB; B = single core, 512KB; C = dual core, 1MB (each); D = dual core, 512MB (each)

3rd & 4th letter= memory control revision such as;
FX-55: XXA2X
FX-57: XXBNX
FX-57 (new stepping)/FX-60: XXB2X
3700+ (new stepping): XXB3X
Opteron 165/170:XXBWX, XXB1X, XXBBX

5th letter= is the revision code, like the E is refering to the San Diego Core

For a more detailed explanation read through this:

Opteron 165:
CCB1E 0550VPMW
CCB1E 0606VPMW
CCB1E 0608MPMW
CCBBE 0610DPMW

Opteron 170:
CCBWE 0550UPMW <- this one is the exception to the rule, this stepping actually has quite a few total duds that can't exceed 2.7ghz. Still, I myself have owned one that did 3ghz.
CCB1E 0550VPMW
CCB1E 0609FPAW

Honorable Mention:
CCBWE 0530TPMW -> most of them cant quite hit 3ghz, more like 2.9-2.95.
CCBWE 0546XPMW -> OK stepping, 2.85-2.9ghz average
CCBWE 0609FPAW -> Do not confuse with the CCB1E 0609FPAW, which is a better CPU. This CCBWE version seems to be a 2.9ghz average.

KNOWN steppings to AVOID if you want at least 2.9ghz:

CCBWE 0607_____(Any processor of that week)
CCBWE 0551_____(Any processor of that week)
CCBWE 0546MPMW
CCBWE 0543TPMW
CCBWE 0534SPMW

Sweet now when my opty arives today 03/16/07 i will be able to see what i am capable of... you rock man!
post #4 of 68
I've been having good luck with my 150, I can hit it with a 12X, 11X and 10X..I'll try 9X next..I really need to get a Lanparty board for it, if I can hit 3100 with it on this mobo I probably will...It's burning in pretty good, I'm having to use less V-Core and have been able to tighten the timings some...



150-CACJE 0603GPBW
BN-E4 Revision


EDIT: These are my newest OC's....I think I'm topped out now with it on this mobo and ram...Not that I'm complaining they have done very well for what they are it amazes me they have kept up this well...You got to love Micron....

I am hitting 2.8+ on my LCB9E 0652 WPMW, its at 1.4v right now orthos stable 8+ hours http://valid.x86-secret.com/show_oc?id=191042 . Mootfox and The Duke are also getting good clocks out of there LCB9Es. I think their at least better than most CCBWEs.


Edit: LCB9E 0652 WPMW http://valid.x86-secret.com/show_oc?id=193096 at 1.4v. Idle is 36c load is 52c for 1hour in Orthos. The LCB9E are turning out real good, even at lower voltage.

Great thread.. well the person mine from said this cpu does 2.7 on stock volts.
Yesterday I tried 1 of the saved CMOS and it was 2950mhz hehe but I dont want to try using the pc a lot because i have bad HSF not even the opty 165 stock one =\\ so I'm here looking for a new HSF

Nice one. Well I have now added you to the list. Sorry for the delay.

Well If I was to reccomend a cooler that im sure will help you would be the Thermalright 120 with a good 90CFM Or above 120mm fan.
