they do have it working, but there is probably some sort of small electrical thing on it that isn't within spec or something. And well it can't be because the 1ghz wasn't out since, it was out at launch, all the other boards can do a gig certified. I think they need to have a 20% margin of error for extreme cases so like a board certified for 900 can probably still run a 1000 , but they aren't going to tell like compaq or HP that that is "certified" without making modifications .
