Well, that's not confirmation that it works, though.
Am I not to take key AMD people words as truth for their own products?
That's no marketing slide we're talking about.
The ones I've read say pending motherboard support, and so far most motherboard manufacturers explicitly said no ECC ram support. We'll need a few days to get first hand user accounts whether the motherboards actually support ECC RAM or not.
Sure, it's all too green right now. As the dust settles down, we'll see how it turns out.
