I am looking for RAM of any size 2gb or less and frequency 667mhz or less in an attempt to find another module that this computer can start from. I need a backup in case the one and only module that currently works dies at some point. I can't find any specs to differentiate the one that works from the ones that don't, so I'm just trying to collect random modules in the hope I will get lucky. If you have any old 256mb or 512mb sticks that are not doing anything, I would be grateful to have them. I am also happy to pay for postage plus something more for larger modules.
