ScienceMark 2.0 is a mathematical program designed to stress the memory subsystems of both desktop/workstation and server environments to determine the read/write latency as well as the overall memory bandwidth available between the CPU and the memory controller.
With all results sitting at around the 10.6 mark there is no really noticeable gain between the different setups, we can again see that the 375MHz FSB vs. 333MHz and 1500MHz memory speed give us a 1 second gain which equates to a 10% performance increase.
The molecular test that takes longer means that we can see a larger difference between scores. Again the biggest notes would have to be the fact that the DDR-3 running at 1066MHz and its default timings manages to lag behind the DDR-2 running at the same speed but at 5-5-5-15. However, when we get more aggressive on the DDR-3 and move it to 7-5-5-10 we see that it manages to be the fastest 1066MHz memory here. Again we can see that the increased FSB and memory speed shows us huge gains.
