I'll make it really simple and quick: I'm completing a PC Build with a 12400f, 6750xt. I had two choices when it came to buying the RAM: 1) DDR4 32GB 3200Mhz CL18 2) DDR5 32GB 5600Mhz CL46 Both were at the SAME price (i live in italy). I bought the DDR5 CL46 one, and now i'm worried for the High CAS Latency. For almost entirely gaming and a little video/photo editing, is my DDR5 5600 C46 better or worse than a DDR4 3200 C18? Have i really made that bad of a choice or it was the better one performance/cost wise?

I've been looking through some DRR5 Ram kits for Ryzen 7000 and have noticed a curious thing about the timings for the ram kits that I've found. I want to start by saying that I have no idea about the intricacies of Ram Timings and Cas Latency and how it truly works. The only I know is that Ryzen 7000 cpus have a tendency to usually favor Ram with lower latency and usually perform better because of that. So, I've mostly looked for Ram kits around the 5000mhz-6000mhz range and have been looking mostly for CL30 or CL32 kits. But when I looked at the specific timings for the kits, I noticed something odd. The CL30 kit starts off faster, but seems to increase in latency by quite a bit in its later timings as compared to the CL32 or even CL36 kits that I've seen. For Example, I've seen some DDR5 6000mhz ram kits from G.Skill with CL30, CL32 and CL36 timings. However, the later timings seem to be pretty mixed. There's [30-40-40-96], [32-38-38-96] and [36-36-36-96] timings listed in their respective specs list. 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. The CL32 kit goes from 32 to 38, which is a +6 in latency, while the CL36 kit stays at a flat 36 in its later timings (again, based purely on the timings listed in its specs). I'm not sure if this is just a little nitpick or fine detail that ultimately doesn't affect performance that much, but it's a weird thing that I just noticed and I'm curious if it has any affect at all in performance. So, does the Cas Latency Timing of DDR5 really matter for Ryzen 7000? And if so, by how much? What do you guys think?

I have a Apacer Panther DDR4 8gb 2400mhz ram stick on my H110-S2PH mobo. It's timing is 16-16-16-36(while on XMP2.0....The sticker on the ram also says it's 16-16-16-36) otherwise on default, it was on 17-17-17-39(xmp off). Because it's stock out and my budget, I have to go for a different brand stick. So the frequency(2400mhz) and capacity(8gb) will be the same but which timing should I buy(CL16 or CL17). And in worst case scenario, if I can't find any ram with similar timing. Then what should I do? Can I get a ram with different timing?

I have 2 8gb sticks of Corsair Vengeance LPX DDR4 3600, but I'm kinda getting confused with the Cas Latency. I want to buy the exact kit again but I cannot find it. CPU-Z Says my CAS# Latency (CL) is "15.0 Clocks", but NZXT-CAM says my ram model is labeled "3600C20" meaning the CL is 20. NZXT-CAM also says that the timing is 15-15-15-36, but I don't know what It means. The Newegg listing's specs said it had a CL of 20, but at this point IDK which one I should trust.

So I just built a new PC with a 3900X, an RTX 2060 (Yes, the GPU is quite anorexic. I had a budget and RTX 3060 Tis were sold out. I'm gonna upgrade once stock is back), MSI B450 Tomahawk Max and 32GB Corsair LPX 3200Mhz CL16 RAM. I know how to do XMP, tune timings, etc. However, I noticed that the CAS latency of my RAM, when XMP is disabled, is CL15 (15-15-15-15-36). What CAS latency does everyone else get when you disable XMP?

Hi, Recently i just upgraded my Gaming Rig & i only use my Desktop PC for 4K Gaming (No Streaming). Never play: COD Warzone, PUBG, CS, Apex, Valorent types of Games. Mostly Playing: FIFA and other story Based Games like Tomb Raider, Far Cry, Assassin Creed, Battlefield, TC Breakpoints, RDR etc. PC Spec: Motherboard: MSI MPG Z690 Carbon Wifi CPU: Intel Core i5 13600KF Cooling: Custom Liquid Cooling Loop RAM: G.Skill Trident Z5 RGB DDR5-5600 CL30-36-36-89 (16GB Single Stick) GPU: ASUS ROG Strix LC RTX 3080 Ti Display: Gigabyte M32U (144Hz IPS 4K) Samsung 970 EVO Plus NVMe M.2 SSD PSU: ASUS ROG Thor 850W Platinum OS: Windows 10 I want to change my DDR5 RAM, currently i am using 1 single stick of 16GB 5600MHz (CL 30 may be). I want to change to 8GB 2 stick 5200MHz (CL 40). I want to know that in DDR5, is there any performance difference issue in 4K Gaming if i switch to CL 30 to CL 40 Also want to know is there any performance difference issue in 4K Gaming if i switch to 5600Mhz to 5200Mhz Be informed that i only use this setup for 4K Gaming (No Streaming), so it doesn't matter if there is any performance difference issue in other cases like video editing, rendering, Streaming etc. as i don't do those things.

Hi there I need to upgrade my laptop's memory capacity, and the only kit available for me right now is a 8GB PNY 2400MHz CL19 stick. My laptop is currently running a 2+4Gb at 2400 CL16. So I was wondering if I could loose too much performance in the switch. Thanks for your time

I'm sure this conversation has happened before. I tried to search for it, but I failed, so here goes: From a practical point of view in everyday application, is there any perceptible value in spending the premium for lower CL memory? Example: Let's say we have CL16 vs CL14 DDR4 memory, both running at the same speed, but the CL14 memory comes with a 25% price increase. Is the value there?

Generally speaking, I've built all my computers to have the lowest CAS latency RAM. In the days of DDR3 1866-2400 this wasn't really that big of a deal, just grab some CAS 12 or lower and slap those bad boys in. However, now we've got DDR4 approaching the 5000 mark, but with CAS latency of 15 or greater. Am I just being a dinosaur when I'd rather drop in a DDR4 2400 with a CAS latency of 10 versus a DDR4 4800 with a CAS latency of 18 or is the greater PC speed able to make up for the difference in latency after a certain GB threshold/performance point? I only ask because my pride has taken a hit a few times on certain subreddits when my builds get criticized for not featuring higher speed RAM despite them having greater latency and I'm admittedly not as knowledgeable about the topic as I'd like to be.

I overclocked my memory for the first time. I know 16-18-18-18 are pretty good timings for 3400 memory. The default XMP was 3200 16-18-18-18 so I was wondering if CPU-Z is always accurate because if it is i'm pretty stoked with this. Thanks for the help bros.

I live in America. So here is the deal, my cpu is definitely holding me back. The frame drops are just too much to ignore and not to mention that I have had this cpu for about 5 years ish now. So basically I am heavily leaning towards picking up a ryzen 3900x (and the other parts needed for it). I don't care that much about budget, but would like to keep the upgrades around $1,000 (max I would go is probably 2000) but keep in mind that I am probably going to keep my power supply, gpu, storage, pc case, peripherals and cpu cooler. When I built this pc I admittedly didn't know what I was getting myself into or how to choose parts. This time around however I am not cheaping out (within reason) and would like to be smart about upgrading my system. However there are several thoughts for consideration on my part... First is that I am thinking it doesn't really make sense to pick up a ryzen r9 3900x without a good gpu to match it, so I don't know how badly I will bottleneck things if I don't upgrade my gpu. Secondly I do a lot of heavy multitasking while playing videogames like watching youtube while playing battlefield 1 or whatever game, I will also start writing my own music soon, so a decent cpu and ram (and plenty of it probably) would be a good idea. Third I would like to overclock my system pretty heavily, so I might need to upgrade my power supply (not certain on that part). Fourth I will be starting to do artificial intelligince research sometime within the upcoming year (in other words I need a decent gpu and I am not sure if I should just upgrade it). Fifth I will be in college for my 3rd year of computer science, so this will be the system that I remote into and do 99.9% of my programming on. Sixth I am thinking about upgrading to an m.2 ssd for my main boot drive so that I have much greater performance (I think its worth it, but I would like your guys thoughts on it as well). Seventh I want really decent ram this time (and could use some help understanding cas latency and ram timings and how that affects real world gaming and work performance). Eighth I want a really decent motherboard this time as well so I could use some help understanding vrm phases and what to look for in a really premium motherboard (and what is just a waste of money) also on that note I have heard that vrm phases barely matter now because of the way ryzen is made. Is this true or am I mistaken? Ninth I am thinking about picking up a second duplicate dell 165 hz monitor (because I have heard that there are issues with having 2 monitors with separate refresh rates plugged into your graphics card). Tenth is it worth it to get 32 gb of ram for my use cases? Eleventh would it be worth waiting for the 3950x to come out purely from a gaming performance perspective? Twelfth should I just upgrade almost everything and start from scratch? Thirteenth should I just bear with it till I graduate and can just upgrade the whole thing in one big swath? Sorry for the wall of text, but as you can see there is a lot of stuff on my mind because there are a lot of things to consider as I am upgrading. Any help would be greatly appreciated...

Hey, I'm planning on upgrading my RAM in my XPS 15 7590, that should arrive next week. I was looking for 32GB RAM total (2x16GB). These look good: HyperX Impac <-- Has low CL. But how do I know if these are compatible with the new XPS. Because some people say that not every RAM-module will work. Any advice? Kind regards

So yeah. I mixed two different ram sticks. One is a Crucial Ballistix 8GB 1600MHz and a Kingston HyperX Fury 4GB 1600 MHz Crucial is my original ram stick, it boots up very fast, I also have my OS in my ssd so no problems there. So when I put the other 4GB, the boot up is slower than ever. Any help on this? I searched a few and said that I should fix the timings and stuff. Any help? Thank you in advanced.

Before I say anything yes I have read the older post about cas latency not changing. Anyway I have set my ram's cas latency from 16 to 15 and changed the values that are usually 2nd and 3rd on ram timing specs (sorry cant remember what they're called) from 18 to 17. I have rebooted about 15 times after that has been set in the bios, not in software, and the only thing that changes are the other two values and not cas latency. Help?

I have 3 DDR3 RAM modules already installed in my system, all running at their rated 1600MHz with 11-11-11-28 timings. I am planning to get a fourth module, which may have lower timings. Can I increase timings on the last module to match my existing ones? I had 2 modules of a 2x4GB kit at first, then I bought another one which is running perfectly. Now I wanna fill up the last slot. There are many CL9 modules being sold, hence the question. System (just in case it matters): CPU - Intel i5 4590 Mobo - Asus H97 M-E RAM - 2 x 4GB Team Elite+ DDR3-1600, 1 x 4GB Team Elite DDR3-1600

I am trying to choose between two different kits of DDR4 RAM (2x8GB). A 3000MHz CL15 and a 2400MHz CL12. I'm not sure which to get especially since benchmarks show very little differences between kits like this and the 3000MHz kit is cheaper (only by a bit).

@MageTank its happening again... Dunno if you noticed, but @LinusTech made yet ANOTHER video spreading partially false information about the effect faster/better timed RAM has on even normal day to day tasks. In his video (availible on Vessel) link below: https://www.vessel.com/videos/f3JMXRNiP?tab=details He yet again claims RAM has near no impact on gaming performance. Whilst on average the boost may not be big, massively popular titles such as, but not limited to; Fallout 4, Ryse Son of Rome, GTA V and The Witcher 3 will see noticeable performance increases by going with faster ram, ESPECIALLY, on lower or mid end CPUs (Athlon 860k, FX 4/6/8/9 series, Core i3s, locked i5s, quad core no HT Xeons). Why is this? Because said CPUs have downsides to their performance, and any sort of decrease in access time will result in directly measurable performance increase. There has been several documented cases of how and when RAM speed and latency improvements offers benefits. By representing his video the way he does, Linus make it sound like the 5-15 USD more you pay for a kit of faster RAM is more like 50-150 USD more, by constantly referring to faster RAM as a "much more expensive choice". The fact that @LinusTech goes as far as to promote estetic's over performance, WHILST claiming that the "enthusiast" segment would agree that spending the money on higher speed is wasted is not just wrong. It is simply sickening. Anything that can increase performance without derailing a budget should be considered as a serious option. Picking slower RAM with LEDs on them offer no benefit at all. It looks ballin, but performs the same OR LESS due to generally worse specifications on kits with LEDs or other fancy effects. At the same time, Linus's builds sometimes feature faster RAM kits, which is often given as a sponsorship or has been bought at some point. But whenever faster RAM is mentioned, it is always brushed aside as if it has no performance benefit. So @LinusTech, Tell me. At what grounds can you claim that the performance increase you get with faster memory is not worth it after reading / watching the following documentation http://www.overclock.net/t/1487162/an-independent-study-does-the-speed-of-ram-directly-affect-fps-during-high-cpu-overhead-scenarios @Slick@nicklmg (tagging you guys too so this maybe gets read.) I also have one more grief with the video, that sounds dumb but to the unknowing computer user, it may not be obvious. When Linus was talking about AMD APUs using system memory and dGPUs (read: graphics cards) using their own memory, a slide of a Nvidia dGPU was shown. This CAN cause the misconception that AMD uses system memory which is slow and terrible and bad (blablabla insert fanboy arguments here). There should have been a brand-agnostic example slide not showing ANY logo, serial code or branding. OR both brands should have been equally represented with a slide each, as to not cause potential confusion and or misconceptions. Why can this cause misconceptions or confusion? Because @LinusTech never really explained what an APU is, he never clarified if it was a graphics card or a CPU with iGPU. Hell, even AMD doesnt clearly call it an APU. Nor does he explain what APUs are commonly used for or where you commonly find them. AMD APU products are labeled A6, A8 or A10 followed by four numbers representing the generation and tier within the product stack. By not being clear on this point, Linus is not being clear to his less knowledgable audience. I hope LMG edits said slide to remove the Nvidia branding before this goes onto "mainstream" platforms such as Youtube as to avoid any ignorant idiots using it as an real argument for or against a product or brand in a open discussion.

So my ram is 2 sticks of 4gb Kingston Hyperx 1866mhz that should run at 1.65V (KHX1866C9D3/4G) But I can't enable XMP-profiles for some reason, but i manually set the ram to 1866mhz @ 1,64V but then my timings went worse. Then upped it to 2133mhz @ 1,7V and got even worse timings. Why is all this? 1333mhz 1.5V @ 9-9-9-24 1866mhz 1.64V @ 11-13-13-34 2133mhz 1.7V @ 11-14-14-36 Will this impact performace in any way? http://www.kingston.com/datasheets/KHX1866C9D3_4G.pdf Why am I not getting the right timings? Thanks in advance!

Hi guys, I currently am the owner of an Intel Core 2 Quad Q8400 processor, and due to a problem with my old motherboard, I had to buy the MSI G41M-P33 Combo. At the moment I only have 4GB of RAM (2x DDR3 2GB 1066MHz), however I am willing to upgrade to 8GB and I've encountered a couple of problems regarding the sticks I should buy. I've seen tons of people with the same motherboard that have problem with 1333MHz memory (three bips, doesn't POST), which is acknowledgedly supported by the mobo. I went to Crucial's website to see which sticks they would recommend and I was quite surprised. They recommend a 1600Mhz 4GB UDIMM stick (http://www.crucial.com/usa/en/g41m-p33-combo/CT5651464) but since so many people had problems with 1333 memory I got a bit suspicious. If it is correct, I am considering buying two 4GB UDIMM 1600 DDR3 Adata sticks (http://www.adata.com/en/dram/specification/152), that have the same specs (including CAS Latency of 11). Do you think it is compatible?

Is it correct so say that G.Skill's Trident X DDR3 RAM which is 2400MHZ at only CAS 9 is much better than the new Kingston (or any other brand for that matter) HyperX DDR4 RAM that's 2133MHZ but 14 CAS latency? Everything about DDR4 says higher CAS latencies than DDR3, but surely the newer generation must be better even with higher latency right?

So lets get down to business, I am setting the clock backwards to the old DDR2 age. I have two different memory sticks, one 1gb Patriot PSD21G6672 PC2-5300 (667 Mhz) and one 2gb Hynix HYMP125U64CP8-S6 AB-C PC2-6400 (800 Mhz) on an old ECS 945GCT-M motherboard. Since that motherboard can only operate in a frequency of 667 Mhz at 1.8v, the Hynix safetly clocks back to 667 Mhz. I've also studied both memory timings on both the modules and figured out that both have the same timing of 5-5-5-15. Usually when you combine two modules together, the board will operate the memory into single-channel mode; but since both have identical timings at the same frequency, they both operate in dual-channel mode. Earlier today, I tested out to see if I can run Team Fortress 2 in this new configuration. I have ran the game before with the Hynix memory and a GEIL 1gb stick; it operated fine without problems, but in different timings and in single-channel mode. I got concerned about the GEIL's specs and thats what caused me to switch and use the Patriot memory. But anyways, when I launched TF2, I immediately searched for a public server. When the map was right about to load, the computer blue screened showing the memory dump loading. I panicked and assumed it was the memory. Link to dump file: https://www.dropbox.com/s/sdkfp0rra0g3037/020715-33406-01.dmp?dl=0 I used memtest86+ to test both modules and both are clean. I tested them separately and together. It seems to me that the memory is probably not the issue, but just in-case, I wanted to ask anyways. I am wondering if the different memories caused the blue screen issue. And does timing really matters for channel modes? Will this configuration effect performance? Will this cause the memory modules, or other parts, to fail in the future due to them being different? Is there any considerations I can take note of? Am I asking too much questions? I know this is such an odd and frequently asked question, because I have searched around and have not seen anyone go to this extent (or maybe there is someone who asked before, but I have not seen anything about it), and I wanted to go into further detail and learn what would happen if I do this kind of experiment. Sorry for such a long paragraph, but thanks in advance for your comments and answers Further Specifications: MOBO: ECS 945GCT-m (Bios AM Inc Ver. 080012 - 04/26/2007) CPU: Core 2 Duo E4500 - 2.20ghz MEM: 1gb - Patriot Patriot PSD21G6672 & 2gb - Hynix HYMP125U64CP8-S6 AB-C GPU: BFG Nvidia 9800 gt 1gb PSU: 350 Watt (some company idk) HDD: ST9160310AS ATA 180Gb @5400 rpm

I was looking on Newegg and I saw this 2 CAS latency DDR3 memory. I was very intrigued by this as the lowest common latency seems to be 6. 2GB stick @ 1333mhz http://www.newegg.com/Product/Product.aspx?Item=9SIA3VM22H4520 4GB stick @ 1600mhz http://www.newegg.com/Product/Product.aspx?Item=9SIA3VM22J6488 8GB stick @ 1600mhz http://www.newegg.com/Product/Product.aspx?Item=9SIA3VM22J7038 Is this for real? Has anyone had any experience with this RAM/This company? The company has very questionable reviews on Newegg, and seems only capable of engrish. I also couldn't locate a forums search feature, so sorry if this has been covered before.

So Corsair makes a set of 16GB (2 x 8GB) RAM sticks running at at 1600 MHz with a Cas Latency of 7. Is anyone using this RAM set and how do they perform? Does anyone know how they compare performance wise to the other 16GB Dominator Platinum sets? For example 1600 MHz C7 vs. 2133 MHz C9 vs. 2400 MHz C11? I know that the performance difference won't be that much however, I'm still curious because the Cas Latency is so low on the set of 1600 MHz RAM. THANK YOU IN ADVANCE!

Hello, I am looking into some different RAM's at the moment and I am focusing in on some Crucial Ballistix Tactical Tracer that I think I will end up going with. My first question is what is the important of low CAS latency? I have seen Linus' video about RAM and RAM speeds and he used different RAM's with higher and lower latency's and speeds and the ones with the lower latency's did relatively better. The normal I have seen on newegg is around CAS Latency 9 but the one I want to get is and 8 so what difference will it make with performance and overall will it have any effect on anything I'm doing? My other question is unrelated to CAS latency. I have found the memory I think I will go with but the triple channel version is not in the led configuration I would like. I have found single sticks of it that seem to be the same just not in triple channel packs and I wanted to know whether it was safe to buy 3 single RAM sticks or look for another RAM set altogether. Link's below 1. http://www.newegg.com/Product/Product.aspx?Item=N82E16820148514 this is the link to the single stick 2. http://www.newegg.com/Product/Product.aspx?Item=N82E16820148523 this is the link to the triple channel set *the one I want to avoid the only difference is the LED's ... I would like the Blue ones Thanks! -Nick

As part of my part time job, I have to order parts online which include memory. However, looking around the market these days, a set of dual 4GB CAS 10 1600MHz kit seem to quite cheaper than the standard CAS 9 equivalent. This brought up a question. Yes I am aware that lower CAS is better, but what are the real world benefits? How much of a difference in real world scenarios does a CAS 10 kit differ from a CAS 9 kit? And is it worth saving £4 a set for a CAS 10 kit? Also, on the topic of memory, the same questions go for memory frequency. Which specific applications is it useful to have a high frequency? And at what is the rough point for diminishing returns? 2133? 2400?
