Review: G.Skill RipjawsX DDR3-1,866MHz RAM on Intel and AMD systems

Power consumption - AMD

Power-draw figures are understandably lower for a processor-only system. Again, there's little to be gained here, and one would need to invest in a low-voltage DDR3 kit - 1.25V or 1.35V - if shaving a few more watts is important to you.
