The regular DDR2 controller does not restrict you to half the storage (that would be a pretty useless controller). The main difference between the old DDR2 controller and the HP controller is the introduction of the altmemphy megafunction in the newer controller. You no longer need the feedback clock in the newer controller. Also, with the new HP controller, I believe they have made some efficiency improvements in the control path.
