DDR3 represents 3 generations of memory, DDR2 represents 2 generations of memory, different models of memory can not be mixed, the same generation of memory, frequency can be backward compatible.
At the same frequency, DDR3 data transmission is much ahead of DDR2, and its performance is better. The larger memory bandwidth means that the data exchange between CPU and memory quality check will be faster, which will improve the overall performance and smoothness of the system.
