Dual-rank DDR5 isn't worth hunting for gaming.

Probably not. The difference is usually 1-3% at best, and you’d only see it in CPU-bound scenarios with a very fast GPU at 1080p low settings. Real-world, sit-down-and-play? You will not notice.

Dual-rank sticks have more memory chips per module, which lets the memory controller juggle data a little better. In synthetic benchmarks and some workstation tasks, that shows. In games, the gains are tiny enough that you’d get more FPS by tuning your timings or enabling XMP.

The problem is dual-rank DDR5 is harder to find, usually costs more, and sometimes forces you into higher latency bins. If you trip over a good deal on a dual-rank kit and your motherboard handles it fine, go for it. But don’t pay a premium or spend hours hunting.

If you’re chasing every last frame for competitive shooters, spend that extra cash on faster RAM speed (6000-6400 MHz CL30 is sweet spot) or a better CPU cooler. That’ll do more for your game than swapping single for dual rank.
