There are serious problems with DDR as main memory... messages.yahoo.com "DDR-200 may or may not be practical in a PC. The DDR noise problem is not a fiction of Intel, it is fundamental physics. Specifically, Faraday's Law, one of Maxwell's equations, tells us that the inductive currents (noise) generated is proportional to the voltage swing. RDRAM uses voltage steps of 0.4 volts at a time; DDR uses 2.5 volts/step. This is why RDRAM can run faster and yet be cleaner. DDR-266 is quite improbable in a PC setting. Unfortunately for DDR, basic physics cannot be finessed." Much of the potential useful lifespan of DDR will be consumed before any platforms with serious volume potential are produced if they are ever produced.
