I know DDR has a bus clock multiplier of x1, DDR 2 = x2, and DDR 3 = x4. But what exactly is a bus clock multiplier and how does it work? Is it similar to a CPU multiplier?
I have CPU question which is off topic but might as well ask while I'm posting...
When overclocking older CPUs like Core 2 Duo which still utilized a FSB, why exactly does increasing the FSB affect the CPU speed? From my limited knowledge, FSB is just the pathway for data transfer that connects the CPU to the Northbridge right? So how does increasing the FSB have any impact on the CPU when they are separate components?
And one last question about the bus that connects the RAM to the MCH (memory bus?). Does this bus always operate at the same speed as the FSB or can it be independently adjusted? Is this what a divider does? How bout all the other buses in the system (PCI, PCIe, ect), are they affected when you increase the FSB? I guess what I'm trying to ask is if all the buses on the motherboard are connected or are they independent?
Thanks!
