AMD Ryzen: 4 vs. 2 Sticks of RAM on R5 5600X for Up to 10% Better Performance

This benchmark started as an AMD Ryzen 5000 memory timings and frequency benchmark (like of 3600 vs. 3200, 3800, with FCLK changes), but morphed into a 2x8GB vs. 4x8GB benchmark.

Now, with Zen 3 and the AMD Ryzen 9 5950X, R9 5900X, R7 5800X, and Ryzen 5 5600X, it’s become clear that 2x8GB vs. 4x8GB can impact performance, although this may not carry to other capacities as you exit single-rank configurations.
