If I recall correctly, the Power PC guide described a few options. They were all based on the system clock and a circuit called the "phase lock loop". All subsystems on an AS/400, including the main CPU have this circuit that is synchronized with the system clock according to a "multiplier". One option is to install a system clock that runs at a speed X. The other option is to set the multiplier for the circuit. The multiplier is set via low-level software API. Nathan M.
