Well great find guys... hopefully the "bh" will give us the thing we need!

Ok. 3rd and 4th letter code the memctrl revision.
Then why would K7 procs have a 5-lettered stepping?
Something doesn't match here.
edit:
Duron got their 5th letter in the beginning of 2001.
Duron 800
AMCA 0101MPMW
Duron 800
AHAAA 0111LPBW
k7 doesnt have on die mem controller they have it in the north/south bridge
My point exactly. Why the 5-lettered code if there's no on die memctrl?Quote:

I'm starting to think it's not mem controller code but rather process details.....which would also explain why air/water OCing performance can often be predicted with the 5-digit code.
OPNs, Steppings, and identification purposes codes or whatever may easily change from a generation to another one as they can develop new codes that adjust to the data that they want to write down about the Processor in itself (I don't recall that K7 has the code matrix for example). The fact that a K7 also got a 5 letter Stepping doesn't necesarily means that the traduction of the code is the same (Though its possible), but as I sayed before, I agree with you that the third and fourth letter aren't just for the Memory Controller Revision.Quote:

The hardest way would be else to have those minor, undocumented revisions, identificated in the Serial Number, something that I don't believe about because it would degrade the importance of these and place them just along the millions of Processors that they already produced. The exeption would be preproduction samples, because I saw already two Processors that starts the Serial Number with an X and are detected as Engineering Samples even though they look and are selled as normal Processors, but that is for another Thread...

Look what i got here:

Will try DICE soon (this cpu is the WR 4000+ cpu, i bought it from a guy who bought it from Rol-Co)
this cpu clocks really nice on air too, 3ghz 1,408v 24/7 and 3,2ghz 1,5v pi stable Air cooled (going under my modded mach2 when it arrives here:banana: :banana: :banana: , later some DICE/LN2)
probably wrong, but i may as well throw it out there, you say why did the FX-57 go from cabne to cabye and back to cabne. Ever think it has something to do with the fab it was made at? were there two different steppings in the same production runs? Could it be that AMD different fabs use different machinery therefor have slightly different compositions, i mean, why even have different steppings, unless its for different machinery.
Maybe all these different steppings (3-4 digits) are simply diffent fabs, with the combo of the two somehow denoting which fab and which proccesor type... we may never know really, but this is a huge step forward, thanks for putting the effort in for this guys.
there's only two fabs that make cpu's for amd.. fab30, and fab36, the latter of which is just starting to ramp up production.Quote:

the 4th digit had @ least 13 different combinations, and has a much better chance of relating to the memory controller
so can i infer that this is a early production 3800x2 possibly without coldbug? i dont have phase right now so i can't try it, but it does 2700 @ 1.56v 24/7 and will do 2790 @ 1.61v for benching.

well if its any answer for you i do 3.0 on phase with an LDBHE 0541..X2 3800Quote:

My friends Opt 148 with CACJE 0552FPEW, something new:cool:
According to the first post, does it mean that my 3700+ San Diego CCBWE 0542VDMW is a Dual Core cpu?:confused:
maybe a toledo with one dead core
I believe that this 5 digit "stepping" refers to mask revisions with obviously the last letter (currently E) referring to a full mask revision and every other letter in front of that referring to partial mask revisions on specific parts AMD have made during the fabbing process.
Heres X2 4800 @ -67C core bios temp....

When will the ADV chips will come out??????:D
Does anyone know something????
I believe they've just released it in Japan. I had one a few months back - here's my review on it: http://www.xtremesystems.org/forums/...ad.php?t=78744Quote:
