DDR vs DDR2 testing
 

What would happen if you were to set the most aggressive timings on your DDR and DDR2 and benchmark it ? Our finding is that the difference is not that great as latency on DDR2 is hindering it. Thus if you use DDR400 and run it at CAS 2, 6-2-2, chances of getting the same scores as a CAS 3, 11-4-4 DDR2 module both running in Dual channel mode is quite high.
