Solved Does DDR2 800 or DDR3 1066 use more power or create more heat??? Tags: Heat Build Power Components Last response: December 1, 2010 11:43 AM in Components Share ahthurungnone November 24, 2010 2:00:51 PM 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. More about : ddr2 800 ddr3 1066 power create heat Best solution sportsfanboy November 24, 2010 2:52:56 PM 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.
