Hi, after a post I've seen from the ASUS rep on their official FB channel, getting 64gb 6000 is quite hard. Maybe the latest AGESA updates can change this as I'm starting to see 6400 stable on 32gb with some tweaking. But I wouldn't have this expectations right from the start.
Do you really have the need for that much ram?
As for the Aorus, I really don't know but I think its the same.
