Rambus, and most of it's imitators, use an AC termination scheme. That means they have a resistor and a capacitor in series to ground. b.t.w they did not invent this, it's a well documented technique from at least 1985, probably much earlier. This means that power is dissipated in the resistors only when something is changing on the bus, and not when it is static. I thought Rambus always used a 28 Ohm impedance bus, which was one of the factors which made motherboard design a challenge to start with. So the answer is that on a heavily loaded bus the dissipation is proportional to the clock speed, and PC1066 will therefore dissipate more. However since it's voltage swings are lower, the problem both with dissipation and RF radiation is less bad than trying to make DDR go faster.
