If you set the FSB to 150MHz and set the memory ratio to 1/1, the memory and FSB are both running at 150MHZ. If you set the FSB to 150 and the memory ratio to 4/3, the FSB will run at 150MHz and the memory will run at 112.5MHz. The FSB is how fast the CPU "talks to" the chipset, the memory speed is how fast the memory "talks to" the chipset.
50% of the instructions that make up the typical X86 multimedia application are of the load/store variety. So yes, you will see a nice little boost in performance. However a 10% increase in memory speed does not give a 10% increase in memory bandwidth, more like 2-3% it seems.
maybe a tad more.
