Thanks Albert. The memory chips are all the same speed and from the same source. When I returned the original stick I thought was causing the problems the source said sometimes the Mac doesn't like certain chips and sent a set made by a different manufacturer (Samsung this time, I think). He tested the original and said it passed. The guy I got the chips from has been extremely reliable and I have bought memory through his company for years. I will try the hardware diagnosis you recommended and try to find the link (I got this computer second-hand through work). I am currently running only two 512MB modules in the machine now and it has been stable except for maybe one instance. Thanks, Mike
