    How can I tell that a 90nm cpu is 90nm?

    Ok I am buying a 90nm from zipzoomfly (googlegear) but they say that specs can change without notice. Currently the specs are at 90nm but I don't want them to ship me a 130nm one.
    So how can I tell via visual inspection (without using CPUZ without pluging the chip in) that a 90nm is a 90nm? (what serial number should I look for?) And finaly what dates are the best chips? (which week)

    Cheers,

    if they say it is 90nm, it is. all the better retailers have different prices for .13 parts.

    if it is a 3000 or 3200 there is no guessing.

    I can't find the webpage at the moment, but when looking at the codes on the chip you'll see something like:

    ADA3500DIK4BI

    Note the DIK, the I between the D and the K indicates a 90nm part. A 130nm Newcastle will be DEP So if you part arrives as ADA3000DEPXXX (last part a number and two letters), then you have a 130nm Newcastle. The K and the P indicate the voltage level.

    This is not true, here is the correct OPN definitions:

    AMD Athlon64 3500+
    ADA3500DIK4BI
    ADA = AMD Athlon64
    3500 = Model Number: 2200MHz
    D = Package Type: 939 Pin lidded OµPGA(Organic Micro Pin Grid Array)
    I = Operating Voltage: 1.4V
    K = Case Temperature: 65° Celcuis
    4 = L2 Cache Size: 512KB
    BI = Core Revision CG (Winchester)

    The I can be used to distinguish between 130nm and 90nm parts, BUT does not indicate 130nm or 90nm.

    Re: How can I tell that a 90nm cpu is 90nm?

    Since 90nm parts run at a different voltage than the 130nm parts, are there any "I"'s that are 130nm?

    Just curious, because while it does indicate voltage, I was under the impression that there were no Newcastles with an I on them.

    The DTR socket 754 chips would be "I" i believe. They run at 1.4v.
    But they ship without heatspreaders, so you'd know immediately

    90nm run at 1.4v default and they do run cool you can tell by looking at the die

    Re: How can I tell that a 90nm cpu is 90nm?

    Well mine is running anything but cool and anything but fast.
    My 754 A64 NewCastle ranned a lot better then this POS. The NewCastle ranned at 2.5Ghz with temp of 38C and at 1.65 volts. (Different mobo ASUS K8NE).
    This one on MSI K8N-Plat runs at 2.4Ghz tops on 1.7Volts and 52C!!!! I mean WTF? Same water cooling setup. (DangerDen).
    The other one on air runs at 47C!

    Actually the DTR chips(81.5W) run on a voltage of 1.5v (E), where as the true Mobile Athlon 64's(62W @ full power) run on a voltage of 1.4v (I), and the Low Voltage Mobile Athlon64's(35W @ full power) run on a voltage of 1.20v (Q).

    As for the desktop chips, Only the winchestor cored run on a voltage of 1.4v (I).
