What is the best DDR5 RAM speed and latency for gaming?

6000MHz with CL30 timings is the sweet spot for gaming, especially with Ryzen 7000/9000 or Intel 13th/14th gen CPUs. Ryzen’s memory controller runs best at 6000MHz, and CL30 keeps latency low without instability. Faster speeds like 6400MHz offer only 1-2% gain in games, not worth chasing. Avoid slower speeds like 5200 or 5600, which will bottleneck a high-end CPU.
