Question/edit: If I have two sticks of DDR2 800mhz RAM and DDR2 533mhz RAM with both in dual channel, and both running at 266mhz (553mhz data rate), will the DDR2 800mhz RAM consume the same or less amount of electricity as the DDR2 533mhz RAM, assuming the same amount of RAM being used in both channels?
Original: If I run DDR2 800mhz rated RAM at 533mhz, still using 1.8 volts, will it decrease the required amount of electricity needed to run the RAM as compared to DDR2 533mhz rated RAM at stock speed and voltage, or will the same amount of electricity be used?
It could if I'm overclocking the CPU and GPU and am on a constrained electricrity limit due to the power supply unit, could mean quite a bit. 5 watts isn't much, but it's something. And it's knowledge.
