Why is it recommended to have a 1:1 ratio of Front-side Bus and DRAM? Does it really affect the performance of the CPU?
Many people advice 1:1 ratio, but there are also testimonies for the opposite.
I quote from FSB:DRAM 1:1 ratio question:
This advice doesn't make any sense for processors with integrated memory controllers, this includes the latest Intel processor and AMD processors since the first Athlon 64 and Opteron processors.
With the memory controller on the North Bridge or Memory Controller Hub, higher frequency memory should still improve performance because:
The only way to really be sure is to measure the performance before and after the change with a trusted test, though.
