Embodiments of the invention relate to a memory control hub (MCH) clock master of an MCH. Typically, in a computer system, a processor is coupled to the MCH by a front-side bus (FSB). Further, an input/output control hub (ICH) is typically coupled to the MCH by a back-side bus or Hub Link. In one embodiment, a host phase locked loop (HPLL) of the MCH clock master receives an FSB clock signal transmitted on the FSB and generates a local synchronous clock signal based upon the FSB clock signal. A delayed lock loop (DLL) of the MCH clock master also receives the FSB clock signal and generates a system clock signal. Particularly, the DLL synchronizes the system clock signal to the local synchronous clock and drives the system clock signal to many different devices on the board.
