I've been looking over some RAM to purchase, and I've gotten a bit uncertain after the latest info regarding dual rank RAM for the Ryzen 5xxx line CPU's.

Would a dual rank 3200mzh CL16 2x16 GB be in a better spot than 3600mhz C17 4x8 GB (two single channel sets)? This is the best CAS latencies I can find within my budget, unless I go lower for something like 3000mhz CL15 2x16 GB, but that particular kit is a corsair running at 1.35 V so I'd perhaps imagine that the 3000mhz would be the max. (havent really done any OC before on RAM)

I also recall seeing a benchmark video where it was said that 3600mhz CL16 is an ideal sweet spot. But I'm sort of curious where best function transforms into diminishing returns and bragging privileges. That being said the rig would be used for gaming and video/audio editing. Which is why I'm thinking about going 32GB rather than 16. My current 6 year old rig for the same purpose is using a single 8GB 1600mhz RAM, due to the fact that I forgot to upgrade it. So I'd imagine anything I pick would feel better on the new rig.
 
Solution
There are certain conditions where the ranks of RAM play a vital role.
  1. Do you have a high end GPU > RTX 2080?
  2. Do you game at high refresh rate 1080p?
If the answer is YES for both, then get 3200Mhz CL16 2x16GB Kit assuming your motherboard has daisy chain.

If the answer is NO, then get anything within your budget as it won't offer any significant performance gains as games would be GPU bound.

Note: Ryzen 5000 series will support 2000Mhz FCLK so get sticks which are capable of overclocking to 4000 to the minimum. If you do not wish to overclock then at least get a 3600Mhz XMP Kit.

All very interesting points to consider. I hope to get an RTX 3070 when they are available again in my country, meanwhile I plan to use my old GTX 970 from my old rig as a placeholder. Currently I game at 1080 60ghz, but I am planning to buy a monitor with higher refresh rate and something like freesync or gsync, depending on what I can find. I'm waiting for my B550 MSI Gaming Edge WiFi to come in the mail, and from my understanding it is daisy chain /fly by, based on a list of motherboards that I found.

I am not really an overclocker, so a kit of 3600mhz 2x16GB that I could afford would have CL18 on it. So I'm not so sure that is a good idea in terms of CAS? However this might change with black friday being around the corner.

The list of 3200 I can pick from based on my budget currently is:

Kingston HyperX Predator DDR4 3200MHz 2x16GB (HX432C16PB3K2/32)

Corsair Vengeance LPX Black DDR4 3200MHz 2x16GB (CMK32GX4M2B3200C16)

G.Skill Aegis DDR4 3200MHz 2x16GB (F4-3200C16D-32GIS)

Corsair Vengeance LPX Black DDR4 3200MHz 2x16GB (CMK32GX4M2D3200C16)

G.Skill Ripjaws V Black DDR4 3200MHz 2x16GB (F4-3200C16D-32GVK)

Corsair Vengeance LPX Black DDR4 3200MHz 2x16GB (CMK32GX4M2E3200C16)

HyperX Fury Black DDR4 3200Mhz 2x16GB (HX432C16FB4K2/32-KO)

Corsair Vengeance Black RGB LED Pro DDR4 3200MHz 2x16GB (CMW32GX4M2C3200C16) (Dont really want this since it has RGB)

Corsair Vengeance LPX Black DDR4 3200MHz 2x16GB (CMK32GX4M2Z3200C16)

Just to share this as well.

If you are gaming at 1440p or higher get 3600cl18 kit there isn't much difference when you calculate latency between 3200cl16 vs 3600cl18. If you are not going to overclock then get the 3600 rated kit.
