Well, this does not make much difference for me as I am going to use XMP profile anyway, and they both guarantee 3200 MHz with 16-18-18-36 timings?
Also, for Ryzen 5 2600 with B450 the ram compatibility is not such a big problem as for the 1s generation of Ryzens.
So, in fact, there is no point in paying a little more premium, as they would behave just alike?
Or maybe some other forum user could shed some more light about the difference between those 2 sets?
