| | Front side bus |
 | | For example, a processor running at 550MHz might be using a 100Mhz FSB; this means there is a clock multiplier setting of 5.5, thus the cpu is set to run at 5.5 times the Mhz speed of the front side bus: basically equating to 100Mhz x 5.5 = 550Mhz. |
 | | The speed at which the PCI bus is set at is a division of the front side bus's speed: eg, a 166mhz front side bus will mean the PCI bus is set to run at 1/5th of the speed of the FSB. |
 | | Usually a motherboard will have FSB speed increments at which these PCI dividers are designed with: typically 66mhz, 100mhz, 133mhz, 166mhz and 200mhz; meaning dividers of one half, one third, one forth and so on, to go with the standard bus speeds. |
