Hey there,
So, Ryzen does like dual ranked ram over single. However the difference isn't all that much anymore. And specially so with DDR5. The main benefit is slightly faster latency. For DDR4 there used to be a bigger performance gap. For dual ranked DIMMS in terms of gaming performance, there would be an improvement in 1% lows, but not a whole lot.
Ideally the best set up is 2 x 32gb Dual ranked at whatever speed.
