If you're going for best performance and that last 2% is important to you then I'd go with 3200 CL14 or 3600 CL16, personally I would be willing to pay slightly more for tighter timing. If you're gonna use the four banks. 3200 CL16 and 3600 CL18 have the same access speed, so in the majority of applications and basically all games, they'll have the same performance. depending on what your ram is you can probably overclock to those anyways without having to waste money on a new kit, or at least overclock to 3600 cl18 infinity fabric can't go above 1933mhz on most ryzen chips so you're probably better off buying 3600 cl16 because it'll probably hit around the same speed as 4000 cl18 underclocked to 3866/3600mhz Get it as soon as Sun, Feb 14. CL stands for CAS latency. Any idea what that means? Now the Infinity Fabric clock, called FCLK works best when in sync with the memory clock (which is exactly half of the Effective Memory Speed). It works mostly in two banks memory. I know that 3600 Cl16 is faster but more expensive. The latency is identical on both setups, but you get more bandwidth and a 200 MHz increase to Infinity Fabric clocks (1600->1800). That being the case, we feel like DDR4-3600 is the sweet spot for the X models, all … Is cl18 really that bad? TEAMGROUP T-Force Vulcan Z DDR4 16GB Kit (2x8GB) 3600MHz (PC4-28800) CL18 Desktop Memory Module Ram TLZGD416G3600HC18JDC01 - Gray. Does the brand matter? Just save money. I figured I wouldn’t NEED to get cl16. Price is about the same for either. So I am building a PC with a ryzen 3700x and am trying to get my hands on a Rtx 3070. My kit is currently running on x470 chipset at cl16-18-18-36 1t at 3200 mhz and it is full stable. Press question mark to learn the rest of the keyboard shortcuts. Press J to jump to the feed. Inside the CPU there are chiplets containing physical cores, those chiplets and cores are connected with each other by a system called Infinity Fabric. Chances are you wont feel any difference. Higher speed benchmarks start at 4:52. For 16GB kits, it only costs $15 more than 3200mhz CL16, but it delivers up to ~5% higher fps in some games. 3200 cl16 vs 3600 cl18 reddit Also I am talking about identical latency CL16-16-16-36, so I know that the 3600 MHz one is faster in comparison but is it worth the extra. Meaning 3600mhz cl18 is better than 3200mhz cl16. How do memory speeds affect performance on the new Zen 2 CPUs? 4.8 out of 5 stars 4,695. I also just noticed the motherboard I was favouring (MSI Gaming Plus MAX) advertises support for up to 4133 MHz, however, in the specifications 3600 MHz are left out. The bigger “pipe” of the faster memory makes up for the higher latency (time to do something) As far as real world performance nearly every use case will show no difference between 3200 vs 3600 vs 3700 ram. Cookies help us deliver our Services. The crucial kits are likely a good bin of Micron E die while the 3600 16-19-19 kit could be Hynix. Hi thanks for the excellent reply. Would result is latency penalties. This is the place to ask! /r/buildapc is a community-driven subreddit dedicated to custom PC assembly. And with ryzen. XMP ~ 3600 MHz CL16-18-18 + XMP Sub Timings @ 1.35 V: ... Test Case 3 ~ 4800 MHz CL18-24-18 + Loose Sub Timings @ 1.50 V: As is the case with all overclocking adventures, your results may vary, so proceed only if you assume all risk. Lower latency is faster. DDR4 3600 CL18 vs CL16 Discussion I've searched around a decent bit but haven't found any benchmarks comparing ram of the same frequency but different cas latency with the i7 8700k. Can you advice me a 3600 32gb kit with similar timings and dual rank? 1 Like. G.Skill Trident Z Neo Series 32GB (2 x 16GB) 288-Pin SDRAM PC4-28800 DDR4 3600MHz CL16-19-19-39 1.35V Desktop Memory Model F4-3600C16D-32GTZNC 4.8 out of 5 stars 1,396 Amazon's Choice for ddr4 3600 … En till grej. I read that the formula for calculating the memory latency in nanoseconds is this: (CAS latency / RAM clock speed) * 2000 = latency in nanoseconds3200MHz cl16-> (16/3200)*2000 = 10 nanoseconds 3600MHz cl18-> (18/3600)*2000 = 10 nanoseconds Does this mean that if the Motherboard supports both 3200MHz and 3600MHz, it doesn't matter if you choose to use 3200MHz cl16 or 3600MHz cl18?
