You didn't have a very big sample size. Here's what Google had to say about the topic based on their systems[1]:
Our first observation is that memory errors
are not rare events. About a third of all
machines in the fleet experience at least
one memory error per year

- baruch 12y agoI don't have a fleet of systems like Google but on the several few thousand servers I look over, I see the number of ECC errors is lower than that. It is however a strong power law distribution, many servers (>70%) see no errors at all, and a few have so many that they are unusable, some are in between and have undetected performance or other impact.
