Thought i'd chime in here that I built a computer for a friend yesterday that had some 8GB sticks. I popped them into my R3E to see if they'd work, and the machine would not post at all. No 8GB density sticks for us.
Rampage III Extreme supports up to 6 x DIMM, Max. 24GB as per Asus Rampage III Extreme website, 8GB module x 6 would be 48GB, I don't think it will be able to run with the 8GB module.
