The FSB of the CPU linked to the Frequency of the RAM via the MCH Strap (CPU/Mem ratio). As people increase FSB, the memory frequency goes up as well. People really like 1:1, which is FSB = Memory Freq. So for example, 400mhz fsb on a Q9450 would equal to 800mhz effective on the memory using 1:1 ratio. Therefore, purchasing 667mhz RAM would be a bad idea.
