Is there a real difference between a quad,triple, or dual channel RAM kit?

Ok, I have read endless threads that seemingly end up just showing performance charts. Others have said that the renaming is just a sales gimmick. So, is it renamed just for the number of dimms that are being used is really what I need a "definitive" answer for. I'd rather get 2 triple channel kits and have an extra set for less basically. If the performance is just based on the IMC and chipset...theorectically it doesn't matter what the RAM is right?

I'm not sure if you're asking if the actual sticks are different, but they're not. As far as being any real world improvement between dual channel and triple channel, there isn't any because the systems currently can't eat the bandwidth enough to make a difference. As far as quad channel, two dual channel sticks parked into 4 slots would achieve the same thing if it's ever released.
Edit: Kits are guaranteed to work together since they've been tested as such. Even though single sticks work together, they haven't been tested. In your specific scenario, buying two triple channel kits will yield you 3 dual channel pairs that haven't been tested and aren't guaranteed to work, but they will.

Already knew that...thanks bud!

So it's just that the sticks haven't been tested together...shooooot. Bought to save myself a little bread then...because in all reality the RAM is going to do what I want it to do...and possible what it doesn't want me to do with it lol.

IIRC ram is ram, you can use tripple or quad channel on a dual channel platform but you will only utilise dual channel due to the IMC and chipset configurations.
for example
x58 borads utilise tripple channel
z68 utilises dual channel
x79 utilises quad channel
so how many channels comes do to the IMC, chipset and as seen below the slot configuration

that would be on an x58 platform? 3 dimms will give you tripple channel, 2 dimmis would give you dual channel right. but sandy bridge only supports dual channel so if you run 3 x 4GB dimms you get flex mode which is 2 dimmins in dual channel and one dimm in single channel.. so it comes down to the cpu IMC and chipset right..

it can get confusing lol as being paltform dependent

No, he is not planning on using only three sticks of memory. If you read the op you would know he is planning to get two triple channel kits and is going to be using four of the sticks, the extra two sticks are spares.

So, to summarize the only difference between a dual channel memory kit, triple channel memory kit or quad channel memory kit is the number of dimms included in the kit.

ok, then try it for us:

run your memory on tripple channel, then bench with http://www.maxxpi.net/pages/downloads/maxxmemsup2---preview-multi.php

then remove one memorystick, to reduce channels to dual. bench again with MaxxMEM² - PreView Multi.
(both same timings)

...and show us your results

yeah i read that about the OP, but just becuase he uses 3 dimms doent not mean he has tripple channel, unless the platform supports it and the IMC then yes.. as far as i can tell he has a sandy bridge platform which will only support dual channel even with 3 dimms you will not get tripple channel but mayb e flex mode where 2 dimms are in dual while one runs in single channel. i run 4 x 4GB dimms in my rig and its dual channel becuase its sandy bridge so just becuase i have 4 dimms doesnt make it that i have quad channel

Yes - Going by his sig rig and what he said, he's buying 6 dimms, and putting 4 of them in his z68 board People are confused because they think he's talking about dual channel vs triple channel performance of an IMC. But he's simply asking if you have to buy specific triple channel or dual channel memory. You don't, a DDR3 stick is a DDR3 stick (ignoring ecc and all that jazz). Manufacturers claim you need to because they "test' it, but most cheap memory isn't even tested at rated speeds, so it's disengenous to say that. You can even mix and match speeds of memory, but you'll be limited by the slowest set you have in there. For example I had 3x2gb 1600CL7 and 3x4gb 1600CL9 all running happily together at the slowest speed (1600CL9).

yes, you can run tripple channel, quad channel ram on a z68.. yes a DDR3 stick is a DDR3 stick so it doesnt matter which you run on a sandy platform, so maximum that can be run is dual channel.

and yes on an X58 that supports tripple channel you will see a difference in proformance.. just to add a quick test for fun guys

this is 4 x 4GB RipjawsX 1600 CL8 on a z68

i think wires were crossed along the way too

@OP, it doesnt matter which DDR3 ram you run, the performance will always revert back to your IMC and platform and configuirations shown in the link i posted in post # 5, thats it

Re-read the op and do it slowly.

I'll be using the second rig in my sig...so f i use 4 random sticks it will still run them quad right?

its a x79 SB-E then yes aslong as they are placed in the correct slots the modules should be in quad channel mode tho can be random sticks but should meet this critea
Quote:
Quad channel mode
This mode is enabled when four, or a multiple of four, memory modules are identical in capacity and speed, and are placed in quad-channel slots. When two memory modules are installed, the system will operate in dual-channel mode. When three memory modules are installed, the system will operate in triple-channel mode.
