Sciencemark

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.

Sciencemark puts the DDR3 in its place. At stock speeds its not much faster than DDR2 modules, it's when we overclock and squeeze the extra bandwidth out we get better results.
