I just read this post.

I always thought that the power consumption of ram is due to the size of ram and less so the number of modules. A 4gb ram has more memory chips than a 2gb ram so it would consume more power.

Does anybody know how much difference in power usage for 2x1gb vs 2x2gb ram? I'm thinking of going 2x1gb for my AMD fusion board since that is probably all it needs to run XBMC in Win 7. The computer will be on 24/7 and will serve solely as an XBMC htpc.

This link is also pretty interesting. Lower voltage ram can save a few watts, which is significant for an Nvidia ION or AMD Fusion system, which uses about 20watts or less.

one thing u need to know is that AMD fusion board
are not Dual-Channel Memory compatible per se...
So stick with 1 x 2GB if your going with windows....

somewhere between 1w-2w

I didn't know the AMD Fusion does not support dual channel memory. Thanks for pointing that out.

yepp! many forgets that

ROLF!



Both articles are so full of fail and ignorance...


First link and an example:

First take this module http://www.newegg.com/Product/Product.as...6820146744

Then this one http://www.newegg.com/Product/Product.as...6820313122

If you have 2 modules of the first and one of the second, wich have more memory chips?


Second link, there is no validity in making a comparison of memory power consumption using different modules of ram, as they use different quantity, quality and layout of chips, components, and specifications. To make a valid comparison of memory power consumption you need to use the same modules and vary the imputable values for the same and so maintaining as many variables as constant as possible. Even if the conclusions of link are right the methodology and analysis is a joke.




The FUD, ignorance and misinformation spread in allegedly tech sites and by individuals with no knowledge what so ever never stop to amuse me. Another nice joke is when people says given Intel or AMD product produce less or more heat based on the TDP of each brand product, whichisn´t true as they aren't measure in the same way, more over when they refer to TDP as power consumption which is even far from the truth that the previous assumption. And I'm not even addressing that taking only TDP into account is crap, as many other variables come into play, as how that heat is dispersed (time, area, others), other heat sources, airflow, and so many others. If you want to illustrate yourself in the matter of AMD or Intel TDP please read this article which is pretty much 100% accurate http://www.anandtech.com/show/2807/2.




To the topic on which RAM solution configuration to choose for your system, eskro already addressed correctly.
