What can we see? First, 6800 Ultra is fully based on the reference design, as was expected. Second, GeForce 6800 design is close to 6800 Ultra, although there are some significant differences, especialy concerning the PSU as the card contents with one power connector. Third, both cards have memory chips only on their front sides, while the back ones feature no sockets for additional chips and are therefore not made for such purposes. But note that the company's engineers installed a large copper heatsink onto the card's back side.
