I have always considered DDR266 as a "non-option" for systems which are stable enough for real commercial use, as opposed to gaming. The reason is fundamentally that at this speed the PCB traces are transmission lines, and need to be properly terminated. If you pretend they are not, or apply some empirical termination scheme (a la DDR) which is not thought through, then noise, jitter, crosstalk and reflections will mean that the system fails under certain hard to define conditions. The Rambus termination scheme is properly designed. If people build it right it will work 100%.
