Question, how does a motherboard differentiate a sempron from an A64 on a socket 754 motherboard? the two processors handle memory clock settings differently dont they? Is the m/b by any chance preset for one vs the other or does it auto detect and set the settings to the appropriate stock? (I guess my biggest question would be, if a m/b was preset for a sempron but was housing an A64, could that be a potential cause for memory issues?)
