When you change the FSB you are altering several CPU parameters at once vs. just changing the RAM frequency. Increasing the CPU clockspeed is where the greatest gains are once the DDR3 RAM is at ~1333 MHz. or higher. How you get the RAM frequency isn't particularly important but getting the maximum CPU clockspeed will deliver the best system performance gains. The CPU does not care if you use the multiplier or the FSB to achieve the highest frequency. It's worth noting that you can skew things out of shape by changing the FSB if you are unable to control all frequencies independently however.
So the answer is: You must test to see what works best for your hardware Edited by AMD4ME - 6/27/12 at 3:06pm
