Official Socket AM2/AM2+ Opteron Most Overclockable Stepping Averages + Info - Overclock.net

**ENTERPRISE** · 09-02-07

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 AM2/AM2+ series

Please also take a moment to visit The Official Order of the Opteron

I also have an Opteron 939 CPU submission thread. Please visit
Official Socket 939 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?

( Not all of this info will apply to AM2 )

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.

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 !

Socket AM2 (940)

Quote:

AM2 processors are incompatible with 939 motherboards and vice versa, and although it has 940 pins, it is incompatible with Socket 940. DDR2 can transfer more data per clock cycle, but suffers from higher latencies, while drawing less power than DDR memory, which the previous Socket 939 supported. AnandTech reported that Socket AM2 system performance was 0-7% faster than Socket 939 equivalents, with most applications about 2% faster, despite having over 30% greater memory bandwidth due to DDR2 support.

The first processor cores to support socket AM2 are the single-core Orleans (Athlon 64) and Manila (Sempron), and the dual-core Windsor (Athlon 64 X2 and Athlon 64 FX). Most processors on Socket AM2 include SSE3 instructions and were developed with 90 nanometer technology. Recent models feature 65 nanometer technology.

Socket AM2 will support upcoming AMD Phenom processors.Socket AM2 is a part of AMD's next generation of CPU sockets, along with Socket F for servers and Socket S1 for mobile computing.

There are also single-socket Opteron processors available for AM2

AM2 Specifics

Socket AM2+

Quote:

Socket AM2+ is a CPU socket which is the immediate successor to Socket AM2 currently used in several AMD processors such as Athlon 64 X2. Socket AM2+ will be a mid migration from Socket AM2 to Socket AM3 and will be fully compatible with Socket AM2, so processors designed for Socket AM2 will work on Socket AM2+ motherboards and vice versa. Socket AM2+ will have some differences however that will be used in AM2+ chips, there are two main features in Socket AM2+ not in Socket AM2:

HyperTransport 3.0 operating at up to 2 GHz
Split power planes: one for the CPU cores, and the other for the Integrated Memory controller (IMC). This will improve power savings especially with integrated graphics if CPU cores in sleep mode but the IMC still active.

AMD confirmed that AM2 processors will work in AM2+ motherboards and AM2+ processors will work on AM2 motherboards. However, due to the lack of support of HyperTransport 3.0 and separated power planes in Socket AM2 motherboards, AM2+ chips will be limited to the specifications of Socket AM2 (HyperTransport 2.0 at the speed of 1 GHz, one power plane for both Cores and IMC). AM2 chips will not benefit from faster HyperTransport and separated power planes on AM2+ motherboards as they do not support them, AM2+ motherboard then fall back to compatibility mode using AM2 specifications.
According to confirmations from AMD, Socket AM2+ will have a compatibility path with Socket AM3, AM3 processors will work in AM2+ motherboards; however, AM2+ processors will not be compatible with AM3 motherboards.

AM2 and 939 thread seperated.

You can find the 939 version here : http://www.overclock.net/amd-cpus/12...ml#post2679767

This is a new thread and is currently under construction !

AmericanNightmare · 09-02-07

Very nice! I look pretty silly sitting there by my lonesome....hopefully there will be some people to contibute to the steppings/overclock list i know there are a few with 1210's floating around OCN.

**ENTERPRISE** · 09-03-07

Yeah I hope we will see some contribution soon !

Norse · 09-03-07

i Doubt many people will go for the opteron when the brisbanes Overclock so nicely and the fact K10 is starting to come around so not many are gona upgrade

**ENTERPRISE** · 09-03-07

We shall have to see. When these products become cheaper you may find people will be more inclined to get an AM2 opty and just overclock. Thats what happend at the end of the Opty 939 era.

The K10 processors won't likely become affordable in comparsion to the K8 for quite awhile. As far as the 1000 series Opterons go they are already fairly inexpensive for a 1210 or 1212 and doubtless will become more so in the near future.

As far as overclocking goes although there is admittedly little information regarding the Brisbanes vs. the Santa Ana's what is availible does not indicate that the Brissy's have any advantage aside from affordability.

http://hwbot.org/hardware.compare.do...39_1&id=1171_1

As more people adopt the AM2 platform and start overclocking the 1000's more i think we'll see that 1000 series Opty's perform as well or even a bit better than the Brissy's but as Enterprise mentioned we just have to wait and see.

swiftshinobi · 09-03-07

The 12xx series Opterons are less popular here because of their high price compared their 5xxx series counterparts and Brisbanes. The only exception to that is the Opteron 1210 (still expensive compared to Brisbanes and the 3800+). It's a shame too. I want a very overclockable processor for cheap. The Opteron seems like a good choice because of the extra cache, but they cost anywhere from $100 to $200+. I could easily get a 5200+, 5600+, or 6000+ if I want the extra cache.

AM2 65NM Brisbane core now listed.

Got this last night after a Vcore mod. Currently testing at 3002mhz/300 x 10/1.5v
