Possible values of an option:
Depend on motherboard model, [Disabled]
The option description:
Defines, whether owe frequencies of buses AGP, PCI and interface SATA synchronously to change together with frequency of the front-side bus ([Disabled]), or AGP, PCI and SATA should clock independently from remaining buses (you can select a suitable variant among the presented values of an option). The second variant is more preferable — it is recommended to fix normal working frequencies of buses AGP (66 MHz), PCI (33 MHz) and interface SATA (100 MHz) that provides stability of operation of the videocard, expansion cards and a disk subsystem without dependence from a level of acceleration of the front-side bus.
