Should I get faster Ram than 1600mhz for i7-3930k with RIVE?

[bcheese]

I bought 32gb of 1600mhz RAM, Corsair Dominator - 1600 - 10-10-10-27 - 1.5V CMP32GX3M4X1600C10 to go with the following build. Some people mentioned that with the GPU's and CPU, I should have selected faster ram - Is there a better RAM I should have grabbed, ie. 1866 or 2133 and perhaps G.Skill Trident or Corsair dominator platinum?

The build is:

Motherboard: Asus Rampage IV Extreme
CPU: Intel i7-3930K 6-Core 3.2GHz Processor
Cooling: < NOTHING YET >
GPU: 2 SLI x SAPPHIRE Vapor-X 100351VXSR Radeon HD 7970 GHz Edition 3GB 384-bit GDDR5 PCI Express 3.0 x16 HDCP CrossFireX
RAM: Corsair Dominator 32GB (4x8GB) DDR3 1600 MHz (PC3 12800) (CMP32GX3M4X1600C10)
Hard-Drives: 2 x SAMSUNG 840 SSD Pro Series MZ-7PD256BW 2.5" 256GB SATA III MLC
Extra Space: WD VelociRaptor WD6000HLHX 600GB 10000 RPM SATA 6.0Gb/s 3.5"
Thermal Paste: Arctic Silver 5
PSU: Corsair HX 1050 1050W ATX12V / EPS12V SLI CrossFire Ready
Blu-Ray: ASUS Black Blu-ray Burner SATA BW-12B1ST/BLK/G/AS
Case: COOLER MASTER Storm Stryker SGC-5000W-KWN1 Black and White Steel ATX Full Tow

The ram card's are good, you can get faster cards but the speed boost is insignificant. Also you have quad channel which already is fast.

The corsair dominator platinum series is insanely expensive so It is Judy not worth to get ram cards of higher frequency.

The added capacity at the time of purchase seemed like a better value than higher speed RAM. I just wasn't sure after some people commented that I should have gone with 1866 or 2133.

If you want better speeds just overclock your current card? Dominators are the best cards for overclocking offered by corsair.

That was originally my thought... I guess I'm wondering, is Overclocking the 1600mhz to 1866 a better option? Doesn't that limit OC the CPU?

 

[Xttony]

What do you mean by limit OC the CPU?

 

[bcheese]

I mean, if you OC the CPU, does that limit how much you can then OC the RAM?

For example, would it have been better to have bought 1866mhz RAM or is this RAM basically the same as 1866 except requiring manual OC?

 

[Xttony]

No you can overclock the CPU and the ram individually.
I have 1600MHz Vengeance cards which I have overclocked to 1866MHz and even 2000MHz and it ran without a problem. Dominator cards are far more overclockable than the vengeance cards.
To overclock I had to increase the voltage to get system stability. Now I'm currently running those cards at 1866MHz with the same timings and voltage 1.6v. All cards are being detected and running at triple channel.

Theoretically It is always better to get Higher frequency cards than to buy a lower frequency cards and overclock it. Since overclocking decreases the life of ram cards so it is not advisable to overclock, but since the real life of a ram card is hardly 4-5 years due to rapid advance in technology you don't need the extra life of the cards.

P.S. Sorry for the super late reply.
