The difference in the memory speed is due to an increase in your Front Side Bus (FSB), ideally your FSB:DRAM would be 1:1, or as close to that as possible. Some motherboards allow you to limit the RAM speed and help you achieve that 1:1 ratio. As long as your system is stable and your memory doesn't over heat there is no problem with the higher memory speed but perhaps you could maintain tigher CAS timings at a lower frequency.
