Crypto Low latency is nice, but the speed you ram runs at determines overall bandwidth, and it's that bandwidth that you need more than anything. ago. Regardless on if one is a better die than the other. The modules can always run slower then the rated spec… That said matching is the preferred option, but not always possible. This isnt a clear question with a clear answer, it is (as anything PC) rich in nuance and detail. Going from 3600Mhz CL18 to 3600Mhz CL16 has negligible gaming improvment on 5xxx Ryzens. Ram is meant mostly for tasks like rendering or benchmarking. How much does CAS latency matter in ddr5 and in which games does it matter the most? Build Help. So the 3600 memory has the same CL latency and faster data rate, making it strictly faster. Generally a typical step down (Given an arbitrary value of 2) will make a kit equal to or greater than one with slightly higher speed and a higher latency. Those are not worth The speed/cas (3200/16 = 200) is essentially the responsiveness of the ram. For a comparable value between different memory frequencies you have to convert it into its true value in nanoseconds. Best rams I've found was like 3200 MHz, 14 CL with calculates into 8. Honestly you have to find the balance between CAS and frequency. RAM speed and latency has always mattered on every single chip to date. Display: Gigabyte M32U (144Hz IPS 4K) Samsung 970 EVO Plus NVMe M. A memory stick capable of running tCL 22 at 6000 MT/s, but has to run tRCD 50, tRP 50, and tRAS 80 will almost definitely perform worse than 30-40-40-50 for the same timings. CAS28 would make that exactly 10ns. You can show this quite easily: 4000/18 = 222 3600/16 = 225 There's 1% Mar 18, 2023 · In terms of timings, the number you actually want to look at for the overall latency is (tCL + tRCD + 8) * 2000 / data rate. If I'm understanding things correctly, it seems like for applications that do a lot of small reads (like games), CAS latency is far more important than raw frequency (because of the latency in getting that data out), so something like a 3200cl14 might perform better than a 3600cl16. I am looking to purchase G. When does CAS Latency matter? (RAM) Ask the community and try to help others with their problems as well. View full post. Edit: All things being equal though higher mhz should help more provided the CAS on it isnt super high. 3600 CL18 is equivalent to 3200CL16, both at 10. cas latency, mhz speed, and first word latency, from what I understand, the first word latency is some sort of combination of the cas and the mhz speed of the ram, and the lower it is the better the ram will perform. 25ns latency. If you're a tweaker, it's going to be Idk much about latency, is it a big difference if I get a pair with 18 CAS latency. The price difference between cl 30 and cl40 6000mhz ddr5 RAM in my region is like 40-50$ (100$ vs 140$). Some apps and hardware benefit more from higher clock speed. Aside from the latency difference, the former uses Samsung ICs and the latter uses Hynix ICs. a lower CL is not better if the frequency is too low, and high frequency is not an upgrade if the CL is too high. The lower the CAS Latency, the better. Latency measurements are taken from RTING website. 0 added Bluetooth LE to the mix, but LE Audio still isn't there yet and actually requires Bluetooth 5. 11. Alot of people harp on about low casand it is good, BUT benches show time and again that games like frequency. #8. Can't seem to turn Gear Down Mode off as it adds quite a bit of latency. For example, you should just ignore any DDR4 RAM below 3200MHz or above CAS latency 18. CL18 at DDR4-4000 is the same time as CL16 at 3600. Also get 16gb of ram. Great comment detailing it Good video and a great topic. Nov 24, 2020 · So i found ram sticks that are cheap ashell (and gud) but the only downside is theyre cl22 aka the cas latency is 22 instead of the usual 16-18. Feb 25, 2011 · Jun 15, 2011. When I was assembling my PC I just simply taken G. That should be the overall first word latency. CAS latency (CL) is specifically how many cycles it takes for your memory to access the first bit of a memory location when it has been requested. its multiplied by 2 because ddr technically runs at half the advertised speed. AFAIK low latency ram is currently only useful for overclocking as it can give you more flexibility with timings. If you look at DDR4-4200 with CL 19 and DDR4-3333 with CL 16 then it looks like the DDR4-3333 should respond faster because its latency is . 2 SSD: https://lmg. 75 ns theoretical latency. 25v vddq/IO 1. Do RAM timings/CAS latency values measurably matter at all for any of these? Finding test data that shows what sort of difference is probably going to be difficult (if not impossible) to find because there's just not much demand for it versus something like gaming. Crypto CAS is how fast is data gathered and stored in simple terms. If it is bandwidth sensitive (e. Note that 3200/16 is near identical latency to 3000/15 in that particular operation. You cannot start a new RAS until the PRE step is done. In theory in the only thing changing the performance out of those two variables is the frequency. 6v. Thank you!! But the Price at the moment just makes DDR5 a very bad deal. Usually better binned memory sticks have lower subtimings in addition to CAS which makes them perform better. I am deciding between G. RAM: G. On a fast cpu out can matter a lot. How much CAS latency will slow you down depends a lot on how your program is accessing memory, but the reason for L1 and L2 As long as the intended CAS latency the system is being run at is higher then the minimum spec of the modules it’ll likely be alright unless serous over clocking is intended. CAS latency has the best performance increase ability if you were to OC. 3200MT/s CL 22 is 13. I don't really want to run into too many issues with crashes, so I was a little apprehensive to go with the higher speed memory. Ram latencies in the days of DDR could provide a slightly better experience, but nowadays you're only talking a few percentage points in terms of frames at the very best. Whether it will make a significant enough difference for you to feel will depend on the specific usage. Pricing for the items goes like this in general: 3600mhz 18 CAS latency for $95 CAD plus taxes 3600mhz 17 CAS latency for $100 CAD plus taxes im going to build a pc soon, and when looking at the ram I got a little confused. So much so that it's I think the only benchmark on HWBOT that's still held by DDR4. A basic DDR4 3200 C16 kit at first seems slower but at C36 the DDR5 would actually be considerably slower. Bought a 2x 16 GB 3200 MHz CL16 (16-18-18-36) ram kit instead of 3200 MHz CL14, and I know lower latency is faster, so would this affect performance in any noticeable way? I couldn't find any 3200 MHz CL14 kits in stock, and even when I did the price was ludicrous, so 3200 MHz CL16 was all I could get to upgrade my 2400 MHz RAM. Mar 20, 2014 · Anyway, I think it is pretty clear, lower CAS Latency is bad. 3200 CL14 is 8. • 4 mo. In our testing, we found that whether higher frequency RAM improves performance or not depends heavily on both the application and the CPU used. But when comparing Zen1/Zen+ to Skylake/Kaby Lake and Zen 2 to Coffee Lake, the scaling is pretty much the same when sticking to settings that are attainable on both platforms. And if it is, does that mean that 5600mhz CL32 is actually faster than 6000mhz CL36 That 5600MT/s tCL 32 does have a lower CAS latency than that 6000MT/s tCL 36. They both matter, but rule of thumb is CAS lower, frequency higher. By how much is a different question. I also saw a reasonably priced DDR4 3733Mhz with 17 CAS Latency for $110 CAD. Building a PC for gaming only, I will be playing at 4K ultra. For general memory latency, PyPrime is super sensitive to latency. 6e9) = 9. 00ns of first-word latency. 0 actually add anything worth mentionning? Bluetooth 3. You want the lowest latency possible on your ram, I use the ram and cache benchmark on Aida 64 to test my latency. This is more or less the baseline of RAM that's both pretty good and CAS latency is measured in clock cycles and is therefore dependant on the frequency of the RAM. boddle88. Thanks for the info! I would have thought that higher CAS would lower the performance gap between D5 and D4, even though D5 is capable of much higher speeds. CAS latency on its own doesnt mean anything, but the combo of frequency + latency does. 99, i know the ram is overpriced in the first place but I Ddr5 6000 is only considered the sweet spot because the imc/uclk will stay 1:1 with the memory speed/mclk, allowing for the best possible latency. It'll keep the system from crashing but performance will be lower. • 2 min. The dimm size is 8gb with a speed of 2400 for the cas 14 one and 2400-2666 for the cas 19 one, depending on the dimm that is already in the laptop. the true latency numbers prove this is wrong. You should ignore any DDR5 RAM below 4800MHz or above CAS latency 40. You don't need more and you don't want less. CAS Latency is just as important as speed, for example: 2666 CL14 > 3000 CL 16 and 3000 CL 14 > 3200 CL 16. The comparison is important to look at for Intel. It does boast some new sound tech though and appears to specifically marketed as a compact bar with big CAS Latency 16 vs 18. 7200 CL34 is 9. Skill TridentZ RGB DDR4 3600mhz ram for my R7 3700x rtx 2080 super build, But i am having trouble finding cas latency 16 in stock, does the cas latency really matter because the cas latency 18 is about 94. You want high bandwidth and low latency, that's why I like to do perf = speed / latency. All else held equal, higher frequency will always be better with the same CAS latency. CAS -- Step 2: tell the RAM which COLUMN to select. Most apps want both. Yes, there is a measurable difference. 2 SSD. Tighter timings and higher frequencies on memory do increase IMC stress. Best I can do is 6200 28-35-30-30 SoC 1. Buildzoid has a relatively short rant on the topic. CAS 13 trying to work at CAS 11 speeds would be considered an OC. I have my eye on the new Ultimea Nova S50, but im concerned about its 15" form factor with my 65" TV. Cas latency used to be like 2 back in the day but RAM was slow AF back then. 2400 CL 14 -> 11. Hardware Unboxed has a couple recent videos on the subject. But there is another important factor affecting the performance of RAM, that is RAM speed. The tRCD+tRP (middle two primary timings) tends to have mixed results, but the majority of benchmarks that look into that timing seem to reach the consensus that it does improve performance. Just wondering if this difference in latency would matter for competitive games such as Apex or Tekken 7. For first word latency, not really because it's sorta overrated and doesn't actually matter that much. I'm only running XMP how much does die type matter when compared to one another? Doesnt really make much difference, at the end of the day you're gonna be running the timings advertised on the kit of RAM. But really less noticicble in just everyday use and gaming. The Data fabric runs at Memclock, the performance differences between 3200 and say 3466 (highest stable memory speed on I haven’t seen any DDR5 comparable to 3200C14 for that matter. You'll never be able to directly compare DDR4 and DDR5 on Ryzen so it's kind of pointless to fret about it. Does soundbar length matter? My Hisense soundbar completely died after 6 weeks of basic use and have been looking at getting a replacement. 75 nanoseconds. As we’ve covered here, mixing memory, in general, isn’t ideal Memory access has a few steps: RAS -- Step 1: tell the RAM which ROW to select. lotsa people think that the higher cas is offsetting the faster clock, so theres no reason to buy fast sticks at all. Does it matter what latency and timing the new RAM has? Can I just go with and 3000MHz CAS 15 RAM… A good gpu and low latency monitor are where you should be focused if gaming is the priority. However much you wanna spend. That said, assuming you are running 18-22-22 timings, moving to 16-19-19 is gonna net maybe 5% best case, and then another 5% perhaps moving to 14-14-14. 5 and 18/36=0. It might be a good bench to add. Data -- Either give data to the RAM, or the RAM gives data to the CPU. 3200 CL 16 -> 10. Jul 3, 2023 · Based purely on these numbers alone, the CL30 kit seems to start off faster, but afterwards the latency seems to increase by quite a bit in the middle (it jumps from 30 to 40, a +10 in latency) while the CL32 and CL36 kits seem to be relatively consistent in comparison. Award. Is that money worth the FPS boost? Sort by: Lazy_Whereas9000. The CAS does not matter very much. r/pcmasterrace A chip A close button. Also on something like ryzen the fabric speed being tied to memory speed matters, and many cpus may have trouble hitting 4000MT/s on Jul 14, 2020 · Jul 14, 2020. Hey there everybody! Super lucky to have just got in a set of Trident Z5 RGB 6000mhz C40! Just learning and this is my second Planning on building a computer but need some advice? This is the place to ask! /r/buildapc is a community-driven subreddit dedicated to custom PC assembly. But latency isn't the whole performance. It's a nice upgrade. Even DDR4 vs 5, you probably get like 10 frames which is not really noticicble. 444 ns, almost the same as 3200 CL15 which is pretty good. CAS(n) - n is the number of clock cycles needed to access an arbitrary memory location. 2. few large transfers) the much higher transfer rate is going to benefit you. First and second gen Ryzens would be measurably better with better cas latency Nd faster clock speed, with the sweet spot being 3600MHz. The closer they are to the original stick the better. Skill DDR5 6400 with a CAS latency of 32. • 2 yr. 75 ns of FWL if that matter ] and I wanted some help to know if it's worth it or if I should look for something with less CAS LATENCY. 3200 c16 isnt great and is lower to the bottom of the barrel binning. SKill RipjawsV DDR4 (1x16 GB) 3200 MHz, 16 CL with obviously calculates into 10 ns latency (don't throw stones at me for buying 1x16 GB only, I've run low on money). Depends a bit on the CPU as well. Generally, 32GB is way more important than faster memory for rendering and video editing. Frequency is how many cycles are done essentially. The CAS alone does not determine that. Further gains can be achieved by tuning subtimings but you can also do that with your current kit. Anything in games will be fine if the priority is video editing, the difference is only massive at CPU limited games, ultra high refresh rates and lower resolutions or quality settings. Ideally you'd have a good mix of both. ago • Edited 2 yr. But I can't get anything 6000 and up stable without no matter voltages. CAS 11 should work with CAS 13, at CAS13 speeds. 0 pretty much only improves on BLE Apr 24, 2022 · ~edit: Performance benefits depend on how latency vs bandwidth sensitive your use case is. Take the mhz and divide by the cas latency to get a general idea of how fast the ram is. 7 ns first-word latency. #1. In this article, we will answer: I'm trying to look for 2x8 GB sticks for a PC and I was wondering how much CAS LATENCY would affect it, I'm currently looking at a Silicon Power SP016GLLTU160N22 16 GB, which says it has 11 CAS LATENCY [ and 13. Memory speed matters for gaming. Business, Economics, and Finance. (for gaming) Aug 30, 2021 · Make sure it's rated to run at 1866 or better Some sticks are rated to run at 1600, 1866 would be considered an OC. On 3600 MHz, everything below 18 is fast, everything below 16 is really fast. Whether it's major and worth the extra idle power consumption - probably not, I really can't tell you, depends on the About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features NFL Sunday Ticket Press Copyright 6. Next number would be the timings. Short answer, not really. Ram doesn't matter much on gaming as many people think it does. With that formula the 6600cl32 is 10% "better". Obviously it won't have much of an impact, considering the major fact in video performance is the video card and, to a lesser extent, the CPU (in terms of a bottleneck for the video card). no lmao not even close cas latency only matters if the speeds are the same a 2400mhz ram will never be as good as 3200mhz not even close why are you even considering Welcome to the official subreddit of the PC Master Race / PCMR! All PC-related content is welcome, including build help, tech support, and any doubt one might have about PC ownership. CL16 at 3200 is exactly the same latency as CL18 at 3600, because 16/32=0. And also note that it doesn't apply between generations, so between ddr4 and ddr5, ddr5 first word latency will be higher, but it will still likely have better performance. 75 ns latency (but optimized for AMD builds). CPU: Intel Core i5 13600KF. However, you can force uclk to match mclk and go up to 6200-6400 ram without a latency penalty. 2666MT/s CL 19 is 14. Ram does matter if you are comparing something like ddr4 3000 and ddr5 5600. My 3000mhz c14 kit hits 3600 c16 overclocked. The CL number states latency in terms of "number of clock cycles". Is Mixing RAM with Different Latency, a Bad Idea? Yes. I'm not very good at overclocking to be honest. The CAS Latency of RAM indicates the number of cycles it takes to get a response from memory once the memory controller sends over a column it needs to access. If you can afford the c14 then do that as it will most likely be samsung bdie and have even further overclocking potential. It isn't significant, but the cas 36 would be faster. kermityfrog. Others (Photoshop) also saw a benefit, but not to as significant of Fclk is not directly related to cas latency - it's the speed of the interconnect between the cores, IMC and other stuff in the CPU. Note: Reddit is dying due to terrible leadership from Cas latency doesn't matter Great video for you from buildzoid himself . Can't speak for Intel CPUs but there are likely tests out there as well. As long as voltages are stock I wouldn't think decreasing timings would decrease lifespan of memory by much. Feb 7, 2022 · In simple terms, CAS latency is the number of clock cycles delayed between the moment your CPU sends a data request to RAM and the time this data is available. 6600cl32 -> 6000/9. g. I guess i have 16CL which is crazy lol if you wanna go with lower go ahead. Well 3200 has much shorter/faster clock cycles than 2400, so even though the CL number It matters on all platforms. With most things ram, it's noticicble if you have a hard number like in a benchmark. PC Spec: Motherboard: MSI MPG Z690 Carbon Wifi. If my 16GB of ram was CAS 11, I might not notice it (as much) but with 8GB I would want more speed, especially when running memory intensive applications. yes you want cl 30. CAS doesn't even matter anymore. They're showing the impact of CAS latency in system memory on video performance. It matters the least on chips with massive caches, like the 5800X3D. CAS latency can be referred to in several different ways. Some (Neat Video) showed a fairly substantial benefit going up to DDR4-3600 with both the Core i9 9900K and Ryzen 9 3900X processors. CAS is latency in cycles, not time, so the higher frequency nullifies the additional cycle required. Reply. Planning on building a computer but need some advice? This is the place to ask! /r/buildapc is a community-driven subreddit dedicated to custom PC assembly. A RAM kit with a CAS latency of 16, for example, can be described as CAS 16 or CL16 or as having If you have the money for a 7800X3D then you have the money for at least 32GB of 6000 C30. Get the combo and either return the RAM (some MCs will allow it; some won't) or consider selling it. It‘s just a crude simplification, but it really isn‘t that important either. That said, 2400MHz would mean your FCLK would only be 1200 instead of 1600 which can make a difference. PRE -- Tell the RAM to start charging up the next ROW. Solution. 7 = 619 points 5600cl28 -> 5600/10 = 560 points. Theres a lot of timings besides CAS many of them matter more than it too. 0 added high-speed transfers over Wi-Fi direct, but again, does that change anything audio-wise? Bluetooth 5. I've noticed that different keyboards have different input latency with most sitting around 20-10ms and "gaming" keyboards at under 10ms. com/lttHow much does RAM Jun 30, 2022 · What does the CL mean in RAM Memory? CL means “CAS Latency”. I would prefer lower latency if the price is only like 5-10$ more. Buy a Samsung 970 EVO Plus NVMe M. It depends on if you can still get your money back on the sticks, but it is worth it. Noob here. I would urge you to spend the extra few dollars for 6000 CL30 if possible. Can somebody Does cas latency really matter for gaming? Help. As long as its ddr4 3200, you're good tho. Would the higher CAS latency actually be a DOWNGRADE. Nov 20, 2022 · CAS latency has an effect only when you are doing non-sequential reads. I'd go 3600 18 and itll likely overclock or can reduce cas by 1 . Crypto Cas 19 is obviously cheaper, but the cad 14 is not a problem. gg/FZkszSign up for Linode to get your $100 in 60-day credit at https://linode. For any standard user that this video is catering to it won't matter. 00 ns CAS latency. Cas latency in and of itself rarely matters.

And then you get more than double the bandwidth. This could matter too as sometimes a system can seem stable (no crashes, BSOD) but it appears at least that the on chip ECC can kick in. But higher frequencies will always have also higher CAS, but does not mean it is slower. 8M subscribers in the buildapc community. I don't think those are particularly good benchmarks. Also keep in mind that if you are in gear down mode CL17 will be CL18 and that is quite slow memory both in latency and clock speed. Right? Business, Economics, and Finance. You also need to take bandwidth into account. For those that don't understand why it's true that the CAS timing doesn't have much impact on performance: Your modern CPU's (by modern I mean since the Pentium 4) don't normally read a single address then begin another RAS strobe and CAS strobe sequence. My question is: does cas latency matter much for the ryzen 3750h? If not, I’m going for the cas 19 ones. I tried combos of my ram from 3200 cl14 to 3733 cl18 andr the 3733 got the best average and min fps. i am building a pc (r 7 7700x + 6800) and the ram comes in a bundle with the mobo (b650 x ax) and cpu, its ddr5 6000 cl38.
