    I tried multiple 1GB PC3200 modules in various MDDs and they all caused the machine lock up in sleep. I'd recommend 4x 512MB.

    I shut this machine down at night so locking up in sleep doesn't matter.

    1) Would this work
    2) Would this make any difference to the reliability of this machine

    No, it will not work. The memory in your link is high density. Your Mac requires low density. Also, it's best to use 4 512MB modules.

    This is 1000% correct !

    You can NOT use high density ram, and 512MB is the max size per stick in that era of ppc macs............


    been there done that :) :)

    Actually, there have been reports of 2 x 1 GB configurations working just fine, though obviously not the OP's, since it is high-density.

    Also, I have successfully used ECC DDR in MDDs - it works, and in many cases it's cheaper than regular DDR because there's less consumer demand for it.

    Yeah, same here. I have a 1GB module (low density) in one of my machines and it works fine. I suspect (but am not certain) that the folks who report problems are using high density. Just in case, I normally suggest trying a 1GB module only when someone has a faulty memory slot. Of course, if you already have the ram, there is no harm in trying it. If you're making a purchase though, it's best to stay safe with something that you know will work.
