RAM Latency CL14 vs CL15 vs CL16

Hello there! I'm building my Ryzen 1700 PC for 5K motovlogging and I'm stuck with the RAM latencies. "Lower is better" is the most common but in Davinci Resolve what is "better"? 30 seconds? 5 minutes? no difference?
The costs of RAM has skyrocketed and now 32GBs of RAM cost more than the CPU+Mobo+Cooling fans

Have a look over here https://www.guru3d.com/articles_pages/amd_ryzen_7_memory_and_tweaking_analysis_review,1.html

DDR4-2933 CL16 is about the sweet spot from a price/perfomance standpoint.

Whats important is true latency, which takes into account CAS Latency and speed.

check out this page for a calculator, lower is better.

Quad channel DDR4-3200 CL14 is the best memory on the market currently.

The theoretical difference between Cl14 3200 & cl16 3200 is 12.5%. How much of that 12.5% you will see will depend on to many factors to give a definitive number.
