Bad choice of wording based on old(er) information on my part.. in the past Single Rank/Dual Rank was commonly used in conjunction with Single Sided/Double Sided ram. In fact "rank" actually refers to how the memory is organized (structured)/accessed.
A rank is a data block typically a width of 64 bits (72 when using error correction)

Dual rank usually = slower due to having having to access 2x
Best described here

"As an example, say a chip has eight memory lines, eight chips are required to reach the 64 bits. A single-rank module therefore needs eight chips. the same configuration in dual rank, twice as many chips must be present in order to enable 64 bits. For the same module capacity this would require twice as many memory chips with half the capacity would be sufficient to achieve this goal."

Are the (2) 16 gb G.Skil modules I just purchased dual ranked or single ranked? I have no idea.

No word yet if its a limit of AMD's memory controller (on die) or of the 370 chipset (designed by Asmedia), however currently only single sided/single rank DIMMs in Dual Channel mode support 2666+

What's the point of the ram if ASUS is saying that AMD locked the frequencies out 😄
I just wonder what is the reasoning of this nanny state like attitude towards memory frequencies?
OCing is not guarantied as well, yet we don't see hard locked multi at 40x? It is especially weird to see these hard locks on ROG motherboards.
I bought Corsair 4000Mhz modules for Ryzen release. They did not even dropped a sweat when I clocked them to 3200Mhz. So clearly there is not much need to be waiting for AMD AMP coded modules to arrive. Though seeing RAM prices now I wouldn't blame anyone for waiting for better prices and more variation on RAM modules.
