Cache Control X allows you to view and configure your backside cache settings. The included utilities allow you to enable or disable the cache "on the fly", change the speed at which your backside cache operates and automatically enable the cache at this speed at boot time. There are also options to disable speculative access (a problem with OldWorld machines that originally did not ship with a G3 or G4 processor) and enable dynamic power management. Altivec support is also automatically enabled.
