    What do the letters associated with Opterons and Athlon64s mean?

    I keep seeing people say they've got an Opteron "CABNE" or similar and today I just saw someone on an american forum list their Athlon64 3500 as "LBBLE 0525". WTF? and how do I find out what my A64 3500 is and in what way is it relevant?

    TIA

    The numbers and letters, as far as I know, refer to the size of the cache, the manufacturing group it comes from, the place where it was made and volatges. I'm sure theres other stuff as well, I've never been able to find a place that can actually tell you what the letters mean though.

    Some batches of processors clock better than others sometimes. Maybe because the manufacturing process was better quality at a certain fabrication plant or at a certain time.
    Pyles got it. The letters indicate the "stepping" or revision, of a processor. Much like programs, processors have small updates (revisions) and so a newer version is released. It may be (as is the case with the opteron) that one revision is more overclockable than another.

    The revisions don't have a big impact for off-the-shelf users, who aren't overclocking, as the updates only fix small problems within the processors, they don't introduce new features. 99% of all users and manufacturers who don't have overclocking in mind won't even take notice of this stepping.

    They just sometimes overclock better.

    Okies?

    Am i correct in saying that in years gone by (back in the original Pentium days) you needed the same stepping of processor for Dual systems? These days it doesn't matter though (just like you used to need the exact same revision of hard drive for a RAID volume)

    the cabne code I believe (I might be wrong) relates to wafers and actual location
    that the die came from on a wafer. and the numbers are date of production
    so 0525 = week 25 of year 05

    The other set of codes describes the processor
    which you can enter into this to describe what you have....
