Does DDR2 800 or DDR3 1066 use more power or create more heat???

So I want to build a very small computer using a thin box to install under my TV to steam movies. I must work with a 300watt supply, so I need low power consuming components that also do not build up much heat.

The standard for ddr2 not overclocked is 1.8v, the standard for ddr3 not overclocked is 1.5. So ddr3 will use less power and there should be less heat to dissipate because of the diminished voltage.
