Thanks for the Info Nick. One of our data center guy tell me that longevity is not as big of a concern now, but he also said that may be because automated maintenance is part of the standard recipe they use now. In any case, more information is always better than less information.
I'm much better now in controlling my urges to tinker. I was a hermit for days when I first built this PC, trying to understand and safely apply all of the overclocking options available. Now, if it were to accidentally reset to factory settings, I'd probably just leave them there.
