DDR2 needs to evolve as high-end memory
 

DDR2 IS INCHING close to the 600MHz clock /1200MHz DDR throughput/PC9600 grading - let's use the correct description after a complaint from a Micron guy - but are all these complex looking heat sink and cooling systems really helping you crank up the last MHz?

The argument is that, to overclock more on the bandwidth side, you have to up the voltage, and so increase the heat output of the DIMMs - and yes, huge, finned heat spreaders or liquid cooling or whatever are needed to take away that heat.
