AMD CPUID Stepping

AMD's CPUID stepping on my 2100+ indicates EAX Stepping is 2. Does this mean it is a Palamino core or a Thoroughbred-A, or something else?

TIA

  1. ummm dunno. try wcpuid.
    if its 8 - 0 then its a tbredA
    if its 8 - 1 its an even better tbredB!

    So is the shape of the core square or rectangular? (or dont you know)
    and does it run at 1.75v or 1.65v
    1.75v = old palomino core = square
    1.65v = newer tbredA or B = smaller and rectangular.

  2. Re: shape of the core.

    Shape doesn't seem to be a good identifying factor.

    Yes, the square core is the palamino. No question.

    Yes, the rectangular core is the tbred. No question.

    Yes, the longer rectangular core is the Barton.

    I have 2 athlon based systems at home for my personal use. An 1800+ and a 2100+. Neither of them do I care to open and pull the processor to just check. :)

    Instead, because I work on alot of computers and I don't always feel inclined to pull the cooler off and examine the core, I choose to use a different method to identify them, hence, I went and got the *AMD* specific cpuid program.

    I will go check for the wcpuid program and look at the values.

    Thanks for the info though.
  3. yep.. there is very little to distinguish between a tbredA and B.

    And looking at the core is just incase you have them lying around :smile:

    the only identifyable differences between the A and the B is the CPU id number and the core stepping code, alo found written on the top of the chip.

    TbredA's have codes like AIURA or AIUGA... the tbredB's have codes starting with 'J' it seems.

    but once again you have to look, thus a program like WCPUID is the best, though u have to know what to look for. (and i cant remember off hand the ID code for the new bartons)

  4. wcpuid 3.1a (from MajorGeeks.com) shows:

    family 6 model 6, stepping id 2 (standard)
    family 7 model 6, stepping id 2 (extended)

    Am I missing something here or mis-interpreting what you are saying in your post?
  5. interesting... ok...
    i just checked mine,
    my XP1700+ tbredA reads:

    family 6 model 8 stepping 0 (standard)
    family 7 model 8 stepping 0 (extended)

    i thought stepping 1 was tbredB... but it might be 2 instead... in anycase, you DONT have a tbredA, so its either a B or a Barton :smile:

    In other words... its GOOD.

  6. Unfortunately the information is somewhat confusing, nonetheless, it indicates that this is the palamino core.

    I will ensure, from this point on that I indicate to the vendor that I am unwilling to accept those chips when I go to buy them.
