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. -- Matthew Fuller (MF4839) | fullermd@over-yonder.net Systems/Network Administrator | http://www.over-yonder.net/~fullermd/ On the Internet, nobody can hear you scream.
