I personally regard both of those as neat tricks, but nothing I'd rely
on.

First, if you have even a suspicion that some of your RAM might be bad,
then in my view the situation's urgent enough to justify running a
dedicated RAM-checker for a day or two.  Second, if you _do_ determine
that a stick of RAM is partially bad, in my view, you really need to
throw it awayarather than try to skirt around the bad area under the
questionable assumption that adjacent RAM is and will remain perfectly
OK.
