If money were no object, 3200MHz CL14 Samsung B-die is the best memory for Ryzen.
If money were no object, I'd take the stuff binned for DDR4-4266 over anything else, and just downclock and tune timings. Might be able to get DDR4-3600 this time around and much higher on Pinnacle Ridge.
Aaaand here it is, in the Samsung E-die list
E-die doesn't clock as high as B-bie, but should be better than Hynix stuff at the very least. This is also dual rank memory, which doesn't clock as high as single rank.
I suppose there could be some tweaking to be made to stabilize XMP 3400MHz timings on 3000-3200MHz...
Dual-rank is harder, but in some circumstances it can perform better than single-rank RAM on Ryzen when compared at the same clockspeed.
With e-die you need different timings to get those clocks up there. Like instead of 16-18-18-38 you will be looking at maybe 14-20-20-52, plus you will want 1.40v vDIMM minimum to get that clockspeed to DDR4-3200. I would definitely look at some of the threads on the xs AMD forum about getting dual-rank Samsung b-die chips to play ball at higher memclocks. It will probably help with the e-die as well.
