Funny, I did it too. One of my favorite undergrad experiments, proves
relativity theory, and there is the always muon catalyzed fusion to muse
over as well.
I don't think memory is all that unstable, especially down where I live.
In Denver, maybe. I think you need a lot of RAM, for a long time, to
see a lot of radiation induced errors, or a source of high energy
