I'm just learning about overclocking for the first time and I'm getting used to the terminology as I design my new system. I'm looking at the X2 specs and I notice they have an FSB of 2000MHz?? Would this mean the multiplier is x1 then for the 3800+ to achieve its clock speed of 2Ghz? That seems kind of wierd from my reading so far, but maybe I'm not understanding something... can someone clarify this?
The newer Athlons don't have a FSB at all. They have a HT (Hyper Transport). It has the speed of 1000MHz but in order to make a fair comparison with other systems the effective frequence of 2000MHz is used.
The reason the Athlon64s don't have a FSB is because the memory controller is integrated in the CPU core. All other systems has the memory controller in the northbridge chipset on the motherboard. This difference is also the reason AMDs newer CPUs kicks ass with all other CPUs.
