Asus ROG Strix Scar II (GL704GW), i7, RTX 2070, 16 Gb Dual-Channel

This is a modified Asus ROG GL704GW that I configured with an extra 8 Gb RAM module. It is clear that Dual Channel config improves considerably the gaming performance (even in greater magnitude than the FPS difference between RTX 2060 and 2070). Have you tested this improvement in your own PCs or laptops? Had you the chance to measure different Latencies (CLs) of your RAM?
What I "researched" is that CLs are not that important for gaming at least, there are some comparison in YouTube. We have to take into account that grater frequencies have also grater latencies.
