Here's one side-by-side you can watch with the same games being played on the same Zen-based system, but with varying RAM clock speeds: https://youtu.be/8H0DEkpEDCE https://youtu.be/8H0DEkpEDCE Generally, the highest-clocked RAM got the best average and min FPS in the games tested. I'm having trouble finding it now, but IIRC I also once saw a side-by-side comparing different RAM latencies, and the differences were not enough to outweigh clock speeds; i.e. overclocking with worse latencies was better than lower latency but lower clock. That being said I've seen non-gaming benchmarks that imply that there is a 3600mhz sweet spot. So it may vary based on workload. I haven't looked into that closely though — I was looking at benchmarks when building a gaming PC, so I had a specific focus :)
