Yeah, for high-end sticks right now, the 14-14-14-34 3200 MHz sticks from G.Skill are about the only ones that seem to work, since they are the right IC, and single-sided. The RGB sticks I just got (review soon) @ 16-16-16-36 3600 MHz also work just fine too. Those straight timings (14-14-14 or 16-16-16) at high speeds seems to be a bit rare (most brands do not offer such timings).
The unfortunate part about the Corsair sticks is that it seems they have two different versions, one has the right IC, the other does not. That sucks for Ryzen users, since there doesn't seem to be a way to know what ICs are present unless you can see the actual sticks in person and read the code on the stick itself.
Its situations like this that have me favor G.Skill for high-end sticks, actually.
But I have to say it now; X99, Intel's first DDR4 entry, had THE EXACT SAME PROBLEMS at launch, with broken memory dividers between 2666 and 3200. That is why although the problem with getting the right memory is a big one, it isn't that unexpected, and as such is relatively minor. Here's to hoping that AMD can get it sorted just like Intel did.
Or look at the picture of the board on the page I linked... you are reading the specs of the bottom M.2 port, which IS slower for sure, but the upper slot is a full speed PCIe 3.0 x4 slot.
