2 x Dual Channel = Quad channel?

This is my RIG I am have already ordered:

*LGA 2011 intel Core i7 3.6ghz (turbo 4Ghz) 4960X Processor
*Corsair H100i
*ASUS rampage 4 black edition
*Cooler master Stryker full tower
*GSkill Trident X DDR3 - 16GB(8x2) or 32GB(8x4) 2400Mhz(depends on your answer)
*Cooler Master Stryker White
*Corsair TX 850W PSU
*1gb 560ti + 1gb 240gt GPUS (Using from my old pc build)
*1TB Segate HDD(Files) + 500GB Segate HDD(System)

My question is : In Market we see several Dual & Quad channel kits with different prices but we always purchase the best with reasonable price right?
So a 32Gb(8x4) Quad channel kits is priced at $480 Whereas a 16GB(8x2) dual kit only costs $200

so tell me If I wanted to do a Quad channel can I buy 2 pieces 16GB(8x2) Rams? cause that will be cheaper and i don't have to pay the extra $80.
If I am gettin the Gskills 16gb(2x8) 2400Mhz of 2 peices so will that make a perfect quad channel with my mobo?
How much chances are there that this is gonna be a perfect quad channel?

(so confusing right? lol anyways I hope someone answers.

PS....Almost forgot I am buying 32gb with (8x4) so will ramdisk work? my mobo is asus rampage 4 black edition i hope it should :p

hey mate i saw the prices but i am currently living in india so they ain't gonna be shipping it there......ebay has options, but it is taking huge shipping money....so i was hunting down all stores in india for the ram but they said in India they only got the 16GB(8x2) dual kit but i require the 32GB so the option i got is 8x4=32gb.... so will buying 2 pieces of trident X dual kits make my pc able to run quad channel?

If you want to guarantee that all four RAM sticks work with your two channel memory controller, the motherboard's manual will often specify that you need to buy a perfectly matched set (a 'quad' kit, 4x8GB).
Mixing RAM modules is frequently not quarantined to work.

RAMdisk software will always work with any amount of memory you have onboard, but your system will perform better with more RAM available, of course.

Consult your motherboard's manual for the types of memory that are compatible.

won't 2 pieces of dual channel work as an quad channel at all? the asus rampage 4 black edition supports it.

Theoretically, they can. But pl ensure that you are buying two Dual Kits with same exact serial number otherwise you'll run into compatibility problem or end up in spending too much for nothing or half the value.

I've searched flipkart but nothing there as such except G.Skill Dual Kit of RipJaws.

Read again. I've mentioned Quad/Dual Channel enabled RAM. Two Dual Channel Kits will work. :)

If you're in India, why did you list the prices you were looking at in dollars instead of INR? Also, why do you insist on DDR3-2400 memory? Even for a ramdisk, I'm not sure you'd notice the difference over DDR3-1600 or DDR3-1866, and you might have a better chance of finding a quad channel kit at those speeds for around the same price as two dual-channel kits.

To answer the original question, no using 2 RAM sticks will not give you quadruple-channel performance. Quad-channel means you have to have four RAM sticks installed (or, if your board has that many slots, in multiples of four), in order to operate in quad-channel mode; using 3 stricks drops you down to triple-channel mode, & using 2 sticks drops you down to dual-channel mode.

So, in terms of (at least theoretical) performance, the 4-stick solution should provide more RAM bandwidth than the 2-stick solution.

my bad friend... for not mentioning the Country currency value....but In India its very hard to find decent Computer parts.....The reason I insisted to go for 2400mhz is because I do rendering work I thought this would make my work a lot faster....parts take a lot of time to get around from here...I either have to buy quad channel of 4x4 or 2 pieces of 16(8x2) there are no other options in India :(

Okay so from what i understand that this is a 50-50 chance.....
If i buy Gskills Trident X 16GB(8x2) of 2pieces carefully with following values.....will it still not work...damn asian markets are getting bad here....

*Check cas latency values are same
*Check the RAM & FSB are same
*Volts are same

Yes, this region is really giving tough time to the gamers/enthusiasts. For your question above that by matching the timings, voltage, speed, Yes. What I mentioned earlier is that ensure the same serial number of the RAMs like CMD64GX3M8A2400C10 (Only for reference purpose). Ensure that serial number on both Dual Kits is same.

Caution: There is no guarantee that two dual kits will together or in terms of optimal compatibility.

Also, on QVL of this mobo, all listed RAMs are operating at 1.65V. So ensure the voltage as well.

no...I think u misunderstood wat I meant to say is I will install 4 ramsticks indeed but with 2 pieces of Dual kits (i.e-the Gskills 16gb(8x2) of 2 pieces....... so that makes 32GB so within that, what i want to know is will that work as quad channel? cause I am using different kits as quad channel of 32gb are not available in india

I got 8 slots in my mobo but rams are so messed up to be purchased correctly...

If you mean video rendering, the higher speed won't make anywhere near enough difference to justify the higher price, as you can see in this article:
http://www.legitreviews.com/ddr3-memory-performance-analysis-on-intel-x79_1779/4
If you mean 3d rendering, that will be done on the video card(s), and the speed of the system ram will make no discernible difference.

2 copies of the exact same model dual-channel kit has a decent chance of working (I don't know why EasyLover claimed they'd have to have the same serial number, that's not possible given how serial numbers work), but a quad-channel kit would be more reliable. Also, if you look at the previous page in that article I linked, running in quad-channel mode instead of dual-channel doesn't have a big effect on performance anyway.

Edit: @EasyLover, I think you're getting serial number confused with part number.

I do 3drendering + video Rendering so the ram was what I thought as the most import and and also as I was impressed by the feature of "Ramdisk" by Asus rampage IV Black Edition I gone with it...but I never thought finding the RAM would be this hard...I got the Mobo and Processor from Taiwan somehow but it was not possible for me to spend so much anymore...now RAM comes at a trouble as they are limited here in India!
Thus Fingers are crossed Hope my 16gb(8x2) of 2pieces works as quad channel! :p say good luck....

With 2x8GB you will get Dual Channel. You can add the RAMs later to create full quad channel. Risk of doing that has already been mentioned.

omg! thats a lot costly! where are u from? and well I still have a 50-50 on my luck now....its so freakin hard to get this rig set up right.
Fingers crossed lol Hope my Rig goes up to be a quad channel!

Okay, a couple of extra things to point out:
1. You don't need a special motherboard to run a ramdisk - there's free software that can do that regardless of what motherboard you have.
2. The 4960X is a lot more expensive than the 4930k for not much performance gain, and when overclocking the performance difference pretty much disappears. If you'd gone with the 4930k instead, you might not be so worried about the extra price of a quad-channel memory kit.

True indeed I foolishly spent extra with 4960X, I could have bought the 4930k but Then again I will overclock at times....and L3 cache is kind of thing might come in hand at a point....but despite that 'Hair sized' difference....I am more concerned How will this setup work :p I Bought each things with a big confidence but never once thought I could have such a bad situation with the RAMS!
however I searched the internet and some people did got lucky with the quad channel condition.... If the ICes doesn't change much in the chip my RAMS of G.Skills 16GB(8x2) 2400mhz of 2 Pieces will easily be a 32gb quad channel

Keep it up dear. Good Luck. Remember buy the dual channel kits with same serial number.
