Dont count on Kingston hitting 150MHz FSB, they wont even rate any of their DIMM's CAS2at 133MHz, although some may force it succesfully. Nor Crucial really, Crucialwill not rate any modules at above spec, and PC150/PC2400 is not a standard (it wont ever be, PC166/PC2700 will however). Mushkin and corsair are the only major players in the overclocked memory game (KingMax gets honorable mention).
