There needs to be a breakdown of MHz vs CL, again... again :-/
Just seems like everyone always forgets of the relationship between MHz and CL. For example, 2133MHz CL9 ~/= 2400MHz CL10 ~/= 2600MHz CL11 in certain applications and MHz can win over CL in others. Point is, you may NOT see any benefits from getting that nice n fancy 3733 CL17 and can possible see a regression. There is a difference/balance between bandwidth (MHz) and speed (CL) and they do affect each other of course. Intel having all their cores connect on chip don't see a large benefit from very fast ram, but AMD does have a history of being more ram speed sensitive including Ryzen with the Infinity Fabric of course directly utilizing system RAM.
