Because there are two cores on...for instance, my AMD Athlon X2, does that mean that since there are two cores, the normal FSB for one core which would be 2000mhz, would be x2 so i can put in 4 sticks of pc 6400 at 800mhz? or does the FSB not change when you add another core? Also is there somewhere i can learn more about how the cores work together? Im pretty new to the whole concept. Thanks!
