CPU Host/3V66/PCI Clock
Possible values of an option:
Depend on motherboard model, there can be a variant [Default]
The option description:
Defines frequencies of the front-side bus, bus AGP and bus PCI for the synchronous chipsets (chipsets at which frequencies of all buses are rigidly connected with each other). In this case the magnification of frequency of the front-side bus inevitably involves also growth of frequencies of buses AGP and PCI that can negatively affect stability of operation of the videocard and expansion cards, therefore at acceleration it is necessary to show the raised care.
Regular frequency of the front-side bus depends on model of the processor, bus AGP and PCI on frequencies of 66 and 33 MHz, accordingly (66.67 and 33.33 MHz if to be more exact) by default work. If among possible values of an option there is a variant [Default], it corresponds to nominal frequencies of all buses.
