    well i got an old test computer p2 400 with an abit board on it pc100 ram, i bought a 512 pc133 ram chip and in installed it in that bad boy and it saw but only 128 of it :( now even though its 133 shoulden't it be backwards compatible and should work on that board at pc100 and the worst case it should be not read it but its only reading 128 of it, is it cuz the board is not 133 or cuz the ram chip could be bad ??? and also it can hold up to 1g so i see why it can't see the hole stick :(

    has someone heard of this before lol or tried this before

    thanks

    Some 100mgz boards have problems with 133mgz ram but most are ok with it. Anyway, have you tried it in different slots to see what happens? If not, I'd try that.

    Also, I assume you don't have the PC100 stick still installed but if you do, remove it.

    Have you checked for BIOS flash updates that might be available for the motherboard at the ABIT website? If not, that's the next thing I'd try.

    Important Announcement
    PC133 Modules are NO LONGER backward compatible with PC100 Machines. To determine the correct memory upgrade for your machine, use the PNY memory configurator.

    What OS?

    If you are using Win98 / start / run / msconfig / General tab / Advanced / make sure there is no limit set on memory

    :D

    A single 512MB chip is probably too much for that board. the maximum amount for a board is determined by the number of slots times the amount per slot. ie 1Gb = 256Mb x 4

    And as stated above, PC 133 is no longer backward compatible. The new chips are manufactured differently. Updating the BIOS may help, but not guaranteed, nor likely.

    Two of my PII400s are limited to 256MB of RAM total. Not many around that would accept one 512MB stick.

    it won't work. i just ran into that problem this past week. putting a 133mhz module in my 100mhz max bandwidth caused some problems. so i sent it back. i'm waiting for another one from crucial. can't wait to put that one in!

    I doubt compatibility is the issue because I would think the PC wouldn't even run if that were the case. I suspect it could be the size of the strip as mentioned by Triple6. As far as PC133 not being backward compatible, that's true for some of the major manufacturers but there are still plenty of PC133 strips that are backward compatible. You need to check with manufacturer before buying to be sure.
