Just that, wanted to know which one is better for my build (Asus M5A99X Evo R2.0 + Amd FX-8320) and if is compatible with my Mobo. Thanks.
 
Solution
The 1866/8 Ripjaws X, the higher bandwidth gives it the edge over the 1600/8 and the 1866/9 sets are same freq but take an an clock tick to perform each action compared to the 1866/8

What I do is score each set of RAM like so:
Mhz / Cas latency
And the more points, the better.
So a chip with a cas latency of 10 @ 1600Mhz (160 points) would be better than a chip with a cas latency of 11 @ 1650 (150 points)
