its the other way around. you don't need 4gb of ram to fully utilize 64bit cpus. instead, you need 64 bit processors to page more than 4 gigs of ram. what you need to fully utilize a 64bit processor is a native 64bit os with native 64bit programs.
too many people adopted the optys and athlons with the 64bit extensions because of the fact that the k8 architecture offered considerably better performance with 32-bit applications.
its amd's implementation of DCA (Direct Connect Architecture) that made the platform revolutionary. the incorporation of an on-chip memory controller would almost be useless (fsb limited) unless paired with an extremely high performance point to point interconnect (HyperTransport).
