Found it here, which also goes into some testing the Guild Wars guys did on their population of gamer PCs: http://www.codeofhonor.com/blog/whose-bug-is-this-anyway (scroll down to "Your computer is broken", around 1% of the systems they tested failed a CPU-to-RAM consistency stress test)
Both of them indicate intermittently defective components in running systems are way more common than anybody assumes.

Here's one for RAM in servers, from Google: http://news.cnet.com/8301-30685_3-10370026-264.html

This is very interesting
But when they say "Memory Error", even though it's something detected/corrected by ECC I'm not sure we can say 'the memory is defective'
It may be a combination of the conditions of power/load/data/time since last refresh and variance between modules.
Since Google appears not to show all the data they have, we probably are not going to get that from them though :/
