Can't decide between...

G.SKILL 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Triple Channel Kit Desktop Memory Model F3-12800CL9T-6GBNQ and G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL7D-4GBRM.

The first one has 9-9-9-24 timings. second: 7-8-7-24-2N. 2N? can someone shed some light on what that means? planning an i7-930 gaming system. my question is, is there really a difference in timings? thanks

Information for the CAS timings can be read: http://www.memorysuppliers.com/caslatwhatis1.html

Yes, there is a difference in timings, but you don't see much of a difference in performance until you start to overclock.

But can you tell us what kind of motherboard you have?

From the looks of it the first kit of RAM is better because it is Tri-channel compared to the Ripjaws Dual Channel. Overall your build will run smoother with 6GB of RAM compared to 4GB of RAM. The only thing that tells me to go with the Ripjaws is that it is $55 cheaper.

I exactly have the same Ripjaws Series 4GB (2 x 2GB) for my current build. It is currently running at 1600 at 7-8-7-24-40 and stable so far. Even though you plan on an i7 930, it is not mandatory to get the triple channel Kit.

If I may go further, I won't even recommend the i7-930 for a gaming system at all. Read this:

It shows that for single GPU build, the X3 440 will be enough.

What GPU are you planning to get, anyway? And for what monitor resolution?
