Jun 14, 2020 20 3 15 I'm about to get RAM for my PC, and I was wondering what are the differences between these? The shop I'm getting my parts from has a G.Skill Trident Z Neo 16 GB (2 x 8 GB) DDR4-3600 CL18 Memory but doesn't have a CL16 kit, are there any differences between these two? Solution It depends on what speed your MB will actuallly run them at. If your computer will actually run them at say 2800 then they both may have differnet timings like CL14 at that speed, and unfortunately I've never seen these figures published. But lower is better. I would get the ones with the lower CL and hope for the best. It won't make a big difference either way. Sort by date Sort by votes

So would a 3400MHz 16CL will be better than a 3600MHz 18CL?

I have a Tomahawk MAX motherboard with a Ryzen 5 3600 and a RTX Super 2070. I also have a choice between a Trident Z Neo 3600Mhz 18CLI and a Trident Z RGB 3466Mhz 16CLI, Should I get the Trident Z RGB Instead? Also are there any difference between the "Z RGB" and "Z Neo"? Also there's a Corsair Vegeance RGB Pro 3200MHz 16CLI for like 30$ less. Last edited: Jun 20, 2020 Upvote 0 Downvote W

Sep 22, 2010 3,789 101 30,340 Here's the math on this. It should be valid since your system can use the full speed of those modules. https://www.techpowerup.com/forums/threads/ddr4-frequency-vs-latency.232240/ Upvote 0 Downvote

If you don't mind doing a manual overclock, you could get a DDR4 3866 or 4000 2x8GB kit for $90-130. Your MSI motherboard should have the bios menu for memory overclocking called Memory Try It! that has presets for memory speeds and you should be able to just set it to 3600 CL16-18-18. Check your bios for Memory Try it! before you decide. https://www.newegg.com/p/pl?N=10000...4 600006072&LeftPriceRange=80 130&Order=PRICE I don't really recommend getting these faster kits unless your motherboard has presets in bios already or you are familiar with at least basic memory overclocking. I know that Patriot Viper Steel Series DDR4 3866-4400 kits use Samsung B-die and the G.Skill kits probably have B-Die as well, but I have no idea about the other brands.
