Check if those are all coming from DIMMs, as opposed to other subsystems (on-die caches).

A few errors per day seems much too frequent, unless you live at a high altitude.

Normal good DIMMs, at least when new, should not have errors more frequently than one error per many months.

Frequent errors may appear with memories that are not seated well in their sockets, or which are old, at least several years old.

Frequent errors may also be caused by more general computer problems, like a bad power supply unit.

Isn't that a lot? I see them only when heavily over clocking .
