Fair enough chaps - the board and CPU I'm looking to pair the Dark Team specifically to is the ASUS Edition 10 / 6850k so although not on the QVL for top end speeds (which I understand is that risk) it should still function towards that threshold. If there is going to be a x4 8gb flavour of the 3000/3200 Quad Team Group Dark available then I might take a punt on those - equally though would putting several Dual Channel x2 4gb sets together be wise/unwise as an alternative? I'll be honest that I'm being drawn to them more on an aesthetic level for my project.
Yes this also works fine.
People need to understand there is no such thing as a dual or quad channel only kit. You can buy a quad channel and split it for two different systems for example. You can buy two dual kits and run them quad channel.
The reason manufacturers list quad channel separately is because quad channel is more demanding on the IC and CPU, as such say a dual kit that runs 4600MHz in dual, if you buy two 4600MHz dual kits and then install in quad channel, you won't get 4600MHz because the IC of the CPU is not capable of achieving this.
However if you buy two dual 4133MHz Samsung B die, they would most likely run 4133MHz quad channel.
So buying the 8 Pack 3200MHz dual kit x2 to create quad channel is absolutely fine, it will run 3200MHz in quad channel without breaking a sweat, in fact its good for around 4000MHz with slack timings.
As myself and 8 Pack keep saying, Samsung B die it the bees knees, it is one of the best IC's in memory to come out, it has such amazing flexibility, crazy tight, or lax with crazy frequency, loves both dual and quad setups, its simply a superb IC and Samsung know it, hence why they charge us so much more for it, but in this instance you really get what you pay for.
