Here we see that the Crucial modules run very closely with the G.Skill modules, even though the Ripjaws are rated for 1600MHz at CL8 timings. We also notice that dropping the timings down at the stock speed makes a bit of difference, but nothing significant. However, when we crank up the speeds we see that the bandwidth starts to make a considerable jump at speeds at 1600MHz and above.
