I had problems on a laptop with memory -- I had two indivdiual DIMMs
that worked fine by themselves, but failed if used together. I
strongly suggest running memtest86. (You can find it in pkgsrc, but I
wonder if that's an older version -- the version at http://www.memtest86.com/
seems to run from a bootable CD, and the pkgsrc version runs from a
floppy.) There's also http://www.memtest.org/, which claims to be a
newer development tree, but I've never tried it.
