The EDAC driver used to be hideously noisy (far worse than you're
seeing here), and it was quietened down quite a bit several years ago.
Still you're seeing quite a bit of action here, so I'd suggest the
following:

0. Pull and reseat all of your RAM.

1. Run a memtest for several hours, hopefully you'll get zero errors
(as these errors you're seeing are all Correctable Errors (CE). Any
errors means bad RAM.

2. Keep and eye on logcheck for a few hours - hopefully they go away.
If they don't, and everything keeps on ticking as normal, I'd ignore
them in logcheck.
