Hi everyone, This would be my first PC built, and I am reading up on overclocking ram, there's so much!!! Anyways, I was wondering, would it be better to get a 3600 CL 18 kit or 3200 CL 16 kit. Doing the latency calculation they come out the same, but I was wondering when it comes to "overclocking" or "tightening"(?) the timings which would be easier: - increasing clock speed: 3200 -> 3600 - lowering latency: CL 18 - > CL 16 The two rams I have in questions aren't my ideal choice, but I wanted stay within my motherboard's QVL. 1. Patriot Viper - PVR416G320C6K 2. G.Skill Trident Z - F4-3600C18D-16GTZRX Thanks!

There is a vagueness in that one I personally would like to see defined. The “sweet spot” for ryzen is 3600 cas 16. I have seen testing to see how much a speed changes the performance of ryzen, but what I haven’t seen is how much cas changes what. I’m not sure if this is because it’s a well known metric or what. I am curious as well.

Based on my research, both 3600/18 and 3200/16 yield the same result when calculated. It seems they should function identically. The optimal point appears to be around 3600/16, though you might find it simpler to adjust timing settings rather than change clock speeds.

I suggest checking out the Gamers Nexus video about Zen 2 RAM/secondary timing settings. Also, consider using the Ryzen RAM calculator; I’d opt for the lower CAS path since it’s not always reliable across all configurations. This video is really helpful—it boosted my low scores by about 2% in some AAA titles with secondary timings alone.
