*sigh* It doesnt make it easier at all. It doesnt remove variables, it adjusts them. There is no more simplified/easier way of overclocking then simply pushing up the FSB. YES adjusting the multiplier can reap more benefits in the end, but it does not make it easier. Lets look at it this way...
Just FSB: adjust FSB to the max the chip will handle stably, and be done
Multiplier and FSB: Lower the multiplier to an insanly low number. Next, bump up the FSB to get the max from your memory, rather then your CPU. Lastly, slowly bump up the multiplier to gain the max from your CPU. Now, when your bumping up the multiplier, most people will end up hitting a "reserved" multiplier (ie: one that will not post with the CPU set to it). In that case, they have to reset the CMOS, and then go back into the BIOS, reset all their custom settings, and start again on the long haul up the multiplier trial and error.
Now, tell me again, which is easier
