When choosing RAM, what are the things to look for?

I am comparing two products, each an 8GB DDR3 dual channel kit.

This first is the Corsair XMS3 Dominator 1600:
http://www.newegg.ca/Product/Product...82E16820145344
The timings are 8-8-8-24 and the clock speed is 1600Mhz.

The second kit is the G.SKILL Ripjaws X:
http://www.newegg.ca/Product/Product...82E16820231476
The timings are 9-11-10-28 and the clock speed is 2133Mhz.

These two kits are roughly in the same price range, and I'm just curious as to which is the better buy.

You need looser timings to support higher clocks which is why the G.skill's don't have as tight timings.

The timings between those 2 kits arent going to offset the speed difference. The set of 1600mhz RAM I have are running at CAS 6, that would make more of a difference. But AMD chips do not like much speed over 1600mhz at the moment while Intel does. Lots of stuff to consider, read that link above. The G Skills would def be better out of those 2 kits. They could probably do 1600mhz at better timings then the Corsairs can.

After visually scanning those articles, it would seem that the G.SKILL is the way to go. Clock speed is what matters primarily, but lower timings will separate modules at the same clock speed. Correct?

That's putting it quite simply, but yes.

Get the G Skill and you can run them @ 7,9,7 24 1T or even at lower timings possibly.

The Dominators will only do the 8,8,8 24 @ 1600Mhz and won't OC worth crap.
