The false negative rate is quite high, but the false positive rate is virtually zero. However, this makes it far from useless, because in cases like the question that started the thread, bad memory *is* extremely likely to be the cause, and a software memory tester is probably going to report that. Given the frequency with which messages on this list say "no, it can't be bad memory because it works under Windows," this is *extremely* useful.
