Re: Motherboard help
The front side bus connects more than just the ram to the CPU it connects all of the rest of the hardware to it as well. The front side bus also determines the speed of the system overall with the use of dividers and multipliers.
For example the data from the PCI buses carry information to the FSB in order to transfer data from the PCI devices to the CPU. This is why when you increase the front side bus speed it also increases not only the CPU frequency but your memory and other components as well. This is why each individual part in an AMD system has what is known as a dividers and multipliers. So when you increase the front side bus you can lower the divider for things such as ram so that they are not affected by the raise in the front side bus.
Although it is not used by the newer CPU's to communicate with the memory it is still used in determining the frequencies of the hardware.
