How do you read AMD stepping codes??

Hi everyone.

I love Intels processor web page. Does AMD have anything like this?? I have some chips that are clocking like mad, and I'm curious what I have here. The 1.4 Duron has no problem @ 2.2 with a 200bus.

XP 1700+
AXDA1700DUT3C
JIUHB 0313SPMW

Duron 1.4
DHD1400LV1C
MIXIB 0343TPMW

Someone help me with these codes! Thanks ~Jim

Xp1700 = Week 13, 2003
Duron = Week 43, 2003

Anything else you want to know?? I can't recall what the alphabets are all for but I know the xp1700 is 1.6V by default. :D

Which ones are the good OCers?
How can you tell if its a "B" core that everyone is talking about? Are all the "B"s 1.5V?

Also, the other top right set of numbers that you didn't post contain the model that the chip was originally marked down from among other data. Not that that implies it will run at that speed, but you may have a good chance to hit close to it or at it with a little extra voltage. My 1700+s were actually a "2600+" and "2700+"(the numbers don't neccesarily correspond to any actually released part and that may be a reason some are marked down.)

Edit: added an example:

if we have a CPU with this info:
AXDA1700DUT3C 9367337260464
JIUHB0302WPMW M C 1999 AMD
the 8th and 9th digits in the upper right block are the original model number. This particular chip was intended to be a 2600+ t-bred and was later relabbelled as a 1700+. We don't know if it will actually perform as a 2600+ or if it failed validation and was speed-binned down. However, its usually better to have a chip that started out life higher all else being equal.

THANKS for all the info guys.
Thats a great link Dustswirl, wish you could check Durons too.

I've never seen that proven, as far as I know it's only speculation.

Even if it is true, it has at best dubious bearing on whether the chip will reach anywhere near that speed. Still, I'd take any edge I can get in hand picking an OC chip.

Especially considering the majority of XP2500's were downgraded from high speed ratings. When you think my XP2500 that does 2.2 Ghz on default voltage has a "25" in those two digits, it makes you wonder if there's any truth to the rumor.
