That is, without a doubt, one of the "silliest" things I've ever heard.
Bad RAM is possible, but a majority of memory errors aren't cause by
manufacturer defects, they're caused by small power fluxuations, solar
radiation, etc. You may simply not be aware of these problems because
the instances of a bit flip are so rare in the life of the machine.
But the bottom line is that if you really cared about your data, you'd
use ECC RAM, period. If you don't invest in ECC RAM, then your data is
going to be subject to these problems.
Everything else is hand waving.
