Hi Goutama Sai Kantamaneni; It turns out that DDR DIMMs get pretty much the same bandwidth per signal pin, and considerably more bandwidth per module pin than Rambus RIMMs. I'm about to post a complete accounting over on the Rambus board.

This is a great example of how improvements to a small part of a system don't usually result in much improvement to the system overall.
