I think we agree that spread spectrum clocking is almost a cheat - a way of passing emissions tests without actually reducing the emissions. Everyone seems to do it now. Spread spectrum does reduce the interference from computers. The energy is transformed closer to white gaussian noise which is the least harmful interference, closest to background or thermal noise. Yes, it is exactly the same amount of total energy. Look at it from FCC's viewpoint, as long the neighbors can watch TV, they won't get any calls. And single frequency (non-spread) energy is much more likely to get into tuner and demods. What does this have to do with DRDRAM? Well, the clock is the signal that is the largest EMI problem in any system and a 4X clock is more of a problem as the traces for any given length look more and more like antennas. I also wonder if SS is even possible for DRDRAM systems, the timing is so tight that any drift in the clock may have deleterious effects. Why doesn't Xilinx support RSL? 'Coz it will be a brisk day in heck when they are willing to pay royalties to include the RAC in their general purpose chips.
