cooper Posted November 30, 2009 Share Posted November 30, 2009 Okay, so it's once again time to think about putting together a new system, and since the energy bill is starting to hurt I thought it might be smart to go with low power use this time around. For most parts of the system it's pretty easy to work out how much power they use, but a notable exception here are the memory modules. Voltage is being reported in the marketing material for pretty much all memory modules, but I can't find anything about the amount of ampere and/or watt they need. I read that DDR2 needs to dissipate 4.4Watt of power, but that was given as a ballpark figure and actual use can be very different. DDR3 was reported on that same page to require 30% less due to its lower operating voltage (1.5 vs 1.8) and other advances. I've recently come across an announcement that G.Skill will soon bring to market so-called 'ECO' memory modules that draw only 1.35 volts. The question on my mind is if the reduction in power use is sufficient to warrant possibly pricier memory. It'll be somewhat slower than top of the line of course, but 7-8-7-24-2N should do just fine for me. Thoughts? Quote Link to comment Share on other sites More sharing options...
