A friend of mine swears by this memory testing utility:
http://reality.sgi.com/cbrady_denver/memtest86/
Apparently it tries a bunch of diffrent test patters that are likely to find
memory problems that a simple test wouldn't find. It is cool because you
just just write the image to a 1.44mb floppy and boot from that to do the
test.
A major downside is how long it takes. It takes around 8 hours on my laptop
to do the full suite of tests. Not very useful for a production server..but
something that probably be done on every system you create before you move
it to producton.
