  You make a good point. If I see an error infrequently, not in the
same location, I can accept that as a soft error. If I see failure at
one location, even only a few times a year, I assume that it is a
marginal part.

  There are several programs which allow changing the refresh rate on a
PC style machine. I find that "soft errors" go away when memory tests
are run on a system with slowed refresh, and the marginal parts are
replaced. I talked to the repair guy again, and he said that people are
not reporting intermittent errors. I don't know if that means they don't
mention them, or the memory tests find them. We do tend to replace
memory as bad if the error rate is non-zero, easier now that prices are down.
