It is pretty clear to see that Ryzen can be fairly dependant on memory frequency, but it depends very much on the sort of test and the nature of the workload on memory accesses. On the benchmarks where it matters, our memory kit was above to push performance up and over 20%, although despite the few benchmarks where this happened, it was outnumbered by benchmarks that had zero or a very minor effect. Some gaming titles had up to a 5-10% difference in average frame rates, but others had zero change.
