    I have two memories sticks and don't know what speed they. They came out of
    a old PC running Intel Celeron 500 Processor...
    There is a white sticker behind both of the sticks which says:

    for the first one:
    28092101
    100 64
    For second one (this one has a sticker in from that says its 64M SDRAM)
    28061401
    100 64

    There are florescent sticker on the back of both with "warranty void if
    removed" on them with the following numbers
    for first one: (the letters 'CC' written in black marker on top of the
    sticker)
    X1312
    warranty void if removed
    000921
    for the second one: (the letters 'CC' written in black marker on top of the
    sticker)
    X1214
    warranty void if removed
    000608

    The ICs on the first one have the following markings:
    TECHLab
    TLS39S6480T-75
    0032

    The ICs on the second one have the following markings
    Tlnnovation
    TC81V66841TL-8
    0023

    any ideas on the speed? (PC???)
    I know the second one is 64M any clue on the first one?
    Does the white sticker mean that they are PC100?
    last question....
    I have a new pC which uses PC133 memory sticks.. what would happen if I used
    PC100 sticks in them?

    Seems like they would be PC100 if they say 100 on them.
    I upgraded a Dell GX-110 with memory, and the BIOS said it was PC133,
    but the specs call for PC100. So maybe the PC100 will work ok if you
    try it out in the PC133 machine.

    Most likely PC100, based on the 100 on the stickers and the 7.5 and 8
    ns timing on the chip part numbers. I also don't think PC133, 64M
    dimms were very common.

    You could probably use the chips on a PC that calls for PC133 if you
    set the memory timing in the bios appropriately (ie, slower).

    My guess. like yours, is that they are 64MB, PC100 sticks.
    I have some PC100 memory sticks which work fine at 133, and some that
    don't.

    Google for Memtest86, which is a free downloadable memory tester. With
    it, you can test them yourself without taking a chance of messing up
    your OS. The current version is 3.2.

    Memtest86 creates a bootable floppy disk that all the tests are done
    from, so this is all done without involving your hard disk or the OS
    on it.
