What is the best DDR5 RAM speed and latency for Ryzen 7000?

6000MHz with CL30 timings is the sweet spot for a 32GB DDR5 kit with Ryzen 7000. The memory controller runs best in 1:1 ratio with Infinity Fabric, which tops out around 6000MHz; going faster switches to a slower 2:1 mode that hurts real-world performance. CL30 is tighter than common CL36 with a small price difference, and two sticks are ideal. Don’t overpay for 6400 or 6800 kits.
