Need help with selecting memory for South Bridge system

Wow, memory is confusing.

I’ve more or less decided on most components of my system and it’ll be something like this:
i7-2600k
ASUS Maximus IV Extreme P67 Mobo
2 x HD 6950 in Crossfire
Crucial RealSSD C300 128GB SATA III SSD
Western Digital WD2002FAEX 2.0TB 7200RPM SATA III HDD
Corsair Professional Series AX1200 PSU (I want a beefy PSU for future proofing, and incase I decide to go with a 3-way SLI/Crossfire setup at some point)

But the memory…. I have no idea.

I think I want to go with 8GB (2 x 4GB), but after that, I’m lost. Newegg has 8GB DDR3 memory at prices ranging from $85 to $320

What do I focus on?

Speed? That goes from 1066 to 2200.
CAS Latency? That goes from 7 to 9?
Is voltage important? Is higher or lower better?

So what is most important, or do I find a balance of these things? What would be best for my setup? I’ll just be using my system for gaming, and I will be overclocking.

Thanks

  1. That motherboard is sexy.

    Memory performance scaling at aything above 1600 isn't much impressive, low latency favor gaming alot more than high frequency.

    These'd be great: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231401&cm_re=8gb_1600-_-20-231-401-_-Product
  2. What are the differences between Ripjaw ($160), Ripjaw X ($200), and Trident + Turbulence ($200)?

    They all have the same speed and timings. The only difference in specification is the Trident + Turbulence is 1.65v versus 1.6v for the other two - is Trident +Turbulence better for overclocking?

    The Ripjaw X is listed as specifically for Sandy Bridge and I am getting a P67 system, but without any different specifications listed, its hard to believe that is more than a sales pitch.

    Here are the three options in neweggs comparison tool:

  3. All that "i5 compatible, i7 compatible, AMD Black Edition" memory is pure marketing gimmick, as long as it's not over 1.65v and withing mobo specification it will work without a problem, Just get the one that's cheapest

    What happens if its over 1.65v? Is 1.6v better than 1.65v then?
  5. No it's just that some chipsets have voltage limitations for the memory (at least on paper), for example p55 according to intel supports up to 1.65v memory, but many people run 1.75-1.8v memory on it just fine. Not sure about P67, but don't worry about it that .05 v won't make any difference at all , $40 more is a joke for the 0.0001% less power consumption
