It should also be noted that there are several motherboards out there that
claim to support 1GB or more of RAM which just plain don't, causing problems
like this because the design is inadequate for the power requirements of that
many chips (I have, unfortunately, had to work with some of these). Sometimes
you can work around it using different types of RAM (buffered vs. unbuffered,
etc) but even this is iffy and not something I'd rely on for anything too
important.
