That's not what the AMD spec
(http://www.amd.com/us-en/assets/content_type/
white_papers_and_tech_docs/24674.pdf , sorry if this link gets broken
up) says -- right on the
front page it says 200MHz DDR is max speed, and again it says so at
page 39 (bottom).

This DDR stuff is confusing sometimes ;-)
