    I have bought some new type SDRAM (256Mb, 133, NCP) although seller
    told me it wouldn't work on pre-2001 motherboards (at that time I
    didn't know mobo was made in 2000). so it doesn't work. windows
    crashes on boot with blue screen and BIOS doesn't show text (!), only
    colored boxes :((((

    I was told by salesman it would work at least as 128Mb. Since it
    doesn't, does it mean SDRAM is broken? I got some guarantee, and
    hopefully they will give me new one but it will be of the same type :(
    If that new module works as 128Mb, is it safe to use it? (computer is
    online 24/7)

    BTW, I have only two slots and here are some details of my system,
    just in case it helps you to help me :)

    Sounds like you need low density RAM, PC100 or maybe even PC66. The
    PC100 should work, the problem is finding it. They're not making any
    more. (at least that I know of)

    Got an eBay ID ? You might find some there, but I would suggest
    corresponding with the vendor. I would also DL the manual for the mobo
    and see what it says about RAM. There may be a jumper or a DIP switch
    that'll allow you to use what you have, although as a 128MB stick.
    Don't hold your breath though, but I would definitely look into it.

    And try computer recyclers.

    EBAY is awash in computer stuff. Tons of 3-4 year old technology very
    cheap. More memory than you can shake a logic probe at.

    From some checking, the intel 810 takes up to PC100 memory.
    Here is a link to the PNY page:

    If you cannot find your MB number, do a search on a Intel 810E.

    Notice the note on the home page about PC133memory being no longer
    backward compatible with PC100. SO i would say you need true PC100
    memory. Maybe some further checking on single or double sided chips
    would be in order to. Some poking around the Intel site on the 810
    chipset specs might give you some more ideas.

    Also, i would strongly advice upgrading your Windows XP to SP2 and all
    the latest updates.

    You need LOW DENSITY PC133 memory. PC100 will not work as your FSB is
    133MHZ and what you bought will only be seen as half of its capacity. Do
    not know what would occur if you use it as it. Might be OK?? no
    experience on that one.

    I may have what you need if you are in the US.
