Noob Memory/Ram Questions.

[doofman]

Hey guys, I've been tossing up between a few different options for ram and have encountered a few questions.

1. What is the difference between 11-11-11-30 2N, 9-9-9-24-2N, 10-11-10-30-2N, what do they mean, which is the best?

2. Difference between a G.Skill Ripjaws X and G.Skill Ripjaws Z?

Thanks for your help.

Difference in timings is primarilay is in the first timing which is the CAS or CL, tells how long it takes to performa an action, so lower is faster, the Ripjaws are an ongoing series/model of DRAM, the X line came out with the Sandy Bridge CPUs and is slightly optimized towards them, the Z series was originally targeted towards the 2011 socket and true Quad channel and was expanded towards the IB line of CPUs
