hello, i`m trying to choose between those 2 ram`s. it`s for an in building system , based on i3 530 cpu and gigabyte h57 board. kind of multipurpose usage , light to medium gaming. can`t find a clear cut recommendation for it. some say that the eco will run with lower temp, designed especially for the 1156 Intel`s, and due to the low voltage, it`ll have room for ram oc/tightening timings. others, that the ripjaws should be potentially more performance ram. the ripjaws come with a slight better "stock" timings (7-7-7-24 vs. eco`s 7-8-7-24) the eco 1.35 v and ripjaws 1.6 v. i`m planning to work on the cpu with Scythe ninja 2 passive cooling. help please.
