The Front Side Bus is the connection with the CPU and RAM (with chipset in between because it has the memory controller)
On K8 CPUs, the memory controller is part of the CPU. So the FSB is inside the CPU. This means that you don't have to worry about it. The northbridge now connects to the CPU vire Hypertransport bus.
Hope this helps
