I found a 64GB model with CL38, though the only CL30 option was a 5600 that was a trade-off.

This applies to gaming scenarios. In games, reduced latency can boost frame rates to single digits. It's worth considering since the cost remains comparable between options.

CAS Latency is measured in clock cycles, not just the smaller number being better. DDR5-6000 CL38 matches the performance of DDR5-5600 CL35 practically. DDR5-5600 CL28 and DDR5-6000 CL30 are actually similar. Therefore, yes, DDR5-5600 CL30 offers lower latency and may be worth it for gaming, but don't assume a faster clock speed always means better overall.

Offers improved response time which matters more for gaming. However, remember that 5600 MT/s with a 30 ns CAS delay is actually higher in absolute latency compared to what 6000 MT/s CL30 would provide. Latency is expressed in clock cycles, meaning a larger number at a faster rate is preferable. For completeness: 6000 MT/s, CL38 → 12.66 ns; 6000 MT/s, CL30 → 10 ns; 5600 MT/s, CL30 → 10.7 ns. Outside benchmarks, such differences are usually unnoticeable.
