Would I see benefit if the RAM is faster than the processor’s FSB

computer-buildingddr3intel-core-i5memory

I always thought processor's FSB was the limit of how fast the RAM could be. However, while configuring a Lenovo laptop, I see options for RAM that's faster than the CPU's FSB

CPU = Intel® Core™ i5-560M Processor (2.66GHz, 3MB L3, 1066MHz FSB)

RAM = 8 GB PC3-10600 DDR3 SDRAM 1333MHz SODIMM Memory (2 DIMM)

Best Answer

  • In short, no, some benchmarks may reveal a small advantage, but its nothing you would notice in the real world.

    This answer does not include overclocking the cpu fsb, which is another subject all together.
