Solar Cluster: Wondering why the effort in sourcing ECC RAM?

Seems I’ve vindicated my decision to chase ECC memory modules for my servers, inspite of ECC DDR3 SODIMMs being harder to find. (Pro tip, a 8GB ECC module will have an organisation of 1Gbit×72.)

Specifically mentioned, is that ECC memory is more resistant to these problems.  (Thanks to Sebastian Pipping for forwarding this.)
