Bus/Core Ratio

[avijay]

What is Bus/Core Ratio. How is it calculated. What is the relationship between system bus speed and the operating frequency of the processor. Is the speed of the FSB the same as the system bus speed. For example, 2GHz processor with a FSB of 667Mhz, what is the bus core ratio.

Take Q6600 for example. FSB is 1066/4=266Mhz. Core ratio is x9. 9 x 266 = ~2.4ghz. The ram will default to 266 x 2 = ~533Mhz. You manipulate the FSB to overclock or underclock the cpu & ram.
