I've heard statements, though, that there ARE a non-trivial number of
motherboards that [fail to] do those sort of things (it probably saves
almost a deci-penny a board, after all). Me, I just stick with ECC
'cuz I like my data. I wonder, though, if anybody has run across
specific makes of boards that get in the way of running ECC; would be
nice to mention it on the motherboards page if so.
