no it is not correct the fsb will be 1333 the ram will be 1600 these two numbers are not dependent on each other. it is diffrent things the 1333 is cpu related frequency 1600 is compunication speed between the cpu and ram..
as per I know there is north bridge chip between cpu and ram. Bus between cpu and north bridge is FSB(front side bus), and bus between ram and north bridge is called memory bus. If memory is of 1600MHz and CPU is of 1333MHz then I think ram will deliver data to north bridge faster than the time on which cpu will get the data from north bridge(though the motherboards FSB is 1600MHz but CPU's max FSB is 1333MHz), because cpu can access data at 1333MHz speed. Now am I correct??
