Full review of Legion 5 Pro is here! th-cam.com/video/HIm8vTualEE/w-d-xo.html I've also tested x8 and x16 memory with DDR5 in 2022 to see if it matters as much as in this video: th-cam.com/video/v8g1_fjmReM/w-d-xo.html
Better yet don't buy a Legion 5 Pro, sigh... I always buy the worst products. All Legion 5 Pro's are basically defective. Even last years legion 5 supposedly had better memory.
In China, the issue is disclosed on 03/30 when Lenovo first launched R9000P. No surprise to me. Till now, all models shipped in China are 4 bank group (2sides), no this issue. Quite a information gap!
OMG this guy is unbelievable. he's got to be the best at it!! REVIEWS TO THE TINIEST DETAILS.... Or better, Reviews how they should be Thank you for this quality
I love a lot of hardware/laptop review youtubers, but this is definitely something that would only be detected and covered on your channel. Amazing amazing stuff, thank you so much for providing this information!
The length of what you went through to thoroughly test this and the collegiality shown is something to respect forever. Hat off to you sir, you deserve a lot more for your continued efforts. Thank you from all of us simps. Just... Wow.
One of the big reasons the performance is so different between these two memory kits is exactly the 1Rx8 vs 1Rx16 nature of the kits. This in particular relates to the bank group architecture used in DDR4. The short answer is that by only using 4 chips, each chip needs to provide 16 bits of data rather than 8, this reduces the amount of parallelism that is available within each chip and thereby driving up the latency of consecutive accesses. The longer timings certainly don't help, but they don't make all the difference. The long answer is that when running in x16 mode DDR4 chips normally run with 2 bank groups, this is in contrast to the 4 bank groups when operating in x4 or x8 mode. Bank groups allow DDR4 to increase parallelism by having multiple independent sets of banks muxed together. By ping ponging between the different banks on consecutive accesses the memory will use the tRRD_S timing, when accessing the same bank group, tRRD_L needs to be used. Having 4 bank groups gives you a 75% chance of being able to hit a different bank group whereas 2 bank groups only allows for 50% chance, sustaining long strings of RRD_S hits is even more in favour of the 4 bank group setup. For example: An access pattern BG0 BG1 BG3 BG1 BG2 BG3 would only hit RRD_S, there are many other possible access patterns of the bank groups that will only hit RRD_S, on the other hand the only access pattern that will exclusively hit RRD_S on 2 bank groups is BG0 BG1 BG0 BG1... It is also easier in terms of data mapping with potentially branching access patterns to guarantee hitting a different bank group on the next access. In short, don't buy memory with only 4 chips on it.
@@chris2214 2R, it means dual rank, see Hardware Unboxed among others for some testing of dual rank performance on desktop. There are similar gains when using JEDEC speed memory in dual rank over single rank.
Thanks for the thorough explanation! Quick question: if you pause the video at 2:52, you can see that both the x8 and x16 RAM sticks have 4 chips... or is the x8 stick dual-sided and hold another 4 chips on its hidden side?
This channel deserves millions of subscribers. I learned so much and I am so impressed with the presentation and how analytical and well-thought out everything is!!! Thank you!
It's because of different bank groups of RAM. 2BG and 4BG, Ryzen runs a lot better on 4BG. You can check your RAM's model by software such as AIDA64, or MemTest 64. For Legion 5 pro. two models of RAM were used: M471A1G44AB0-CWE is of 2BG, and M471A1K43DB1-CWE is of 4BG.
To explain this, you need to understand that a “memory rank” is a 64-bit row of memory chips on a memory module. 2R = two memory ranks per module. 1R = one memory rank per module. 2R memory is often called “dual sided”, as the chips for the different ranks are usually put on opposite faces of the module. Dual rank memory (e.g. 2Rx16) has lower latency than single rank memory, because the memory ranks can be accessed independently. Because RAM needs to regularly be refreshed, and all the data in a rank refreshes at the same time, having two memory ranks allows data to be written or read from one of the ranks while the other rank of the channel is refreshing, which means the CPU doesn’t need to wait for the memory to complete its refresh before writing data, as it can switch to the other rank. This way of switching between ranks between refreshes is called “interleaving”. Interleaving reduces latency and improves memory performance, but it also puts additional stress on the CPU’s integrated memory controller, which has to directly manage the interleaving process. Because of this, some older CPUs with weak memory controllers cannot run dual rank memory at the same frequency as single rank. There is a trade off between frequency and latency when choosing between dual-rank and single-rank memory. For modern CPUs (e.g. Ryzen 3000-series and newer, Intel 8th gen and newer) dual rank memory is usually best, as these CPUs can easily manage interleaving for dual-rank memory at high speeds (4000MHz+). If you have a motherboard with 4 memory slots, memory ranks can be interleaved between separate modules - for example, if you install 4 single-rank memory modules, you will have two channels with 2 memory ranks each, and you will get the same performance benefits as with 2 dual-rank modules. You can run triple-rank by using two 1R modules and two 2R modules, or quad-rank using four 2R modules, though the performance benefits from going above 2 ranks per channel is minimal, and it puts additional stress on the memory controller. The x8 or x16 refers to the bus width of the individual memory chips, and is related to the arrangement of the internal memory banks. As each rank is 64 bits, a 1Rx8 memory module will have 64/8=8 memory chips on it, and a 1Rx16 memory module will have 64/16=4 memory chips on it. Modules using x16 chips are usually cheaper but almost always slower than those using x8, due to having fewer banks, which effectively increases latency and reduces bandwidth because accessing data in different banks is faster than accessing data in the same bank, and also due to the use of higher-density nodes with lower manufacturing costs but worse stability at low latencies and high clock speeds.
@@igronDCi like how dude above has wrote the massive explanation text about haw ram works and that you appeared «naah, tldr. Long story short 2rx8 > 1rx8 > 1rx16»
Nice video Jarrod. I really appreciate the thorough investigation. This type of attention to nuances and details ensures that we get the best bang for the buck. Not many people have time or expertise to go through datasheets, so thank you for spoiling us with such useful information. :)
Thank you for sharing this info! I also have the 2021 Lenovo Legion 5 with the 3060 and a 5800H. My device also comes with the same Ram Memory as your device, mine is purchased from UAE. With your video now I am trying to find a suitable Ram Memory preferably a 32GB version.
Hi there! Really appreciate your video. You mentioned in the video that you weren't sure whether the performance increase was related more to the extended timings vs. the upgrade to 1rx8. I can confirm that it's almost entirely from the 1x8. Got a new Lenovo Legion 5 Pro with low tRFC 1rx16 memory (HMAA1GS6CJR6N-XN). Nearly a 10% CPU bench performance increase when upgrading to 1rx8 with identical timings (only difference was CL 22 -> 20).
Cheers for discovering this Jarod! I tried grid autosport was getting average of 100fps and minimum of 72fps. Upgraded to some Kingston hyperX and my average FPS was 115fps and lows of 95fps
My Legion 5 arrived yesterday, il be swapping out the RAM and getting the performance boost thanks to you. Just another reason why im now a patron. Your the best laptop reviewer there is.
I know this is a year old, but just got a L5pro on the cheap and yeah, huge boost in min FPS after I followed the advice here and got some 2rx8 RAM. Thanks mate.
Thanks Jared for the thorough investigation on this. Never seen changing memory kit for laptop with same speed and latency bringing that much performance difference. May be a deliberate attempt by Lenovo to downplay Legion 5 series compared to 7 series. Would you be checking this for the Omen 15 as well?
Hey, thanks for your advise. I followed the same tip for my Asus TUF A15 2021, which had the same slow Samsung RAM. I upgraded it to Crucials CT8G4SFRA32A which comes as dual rank and even better tRFC timings. The increase in performance is insane! I never thought that this tiny details can mean so much. Thanks again!
@@shycreation9418 Well it did for me. But it depends on the limiting factor. If its the GPU you wont get much more FPS by switching the RAM. If its not the GPU and you are using the slow retail RAM, iam pretty sure you will get some more FPS.
Happy I put the exact same ram upgrade in my 5p runs so good!! 2x8gb crucial perfect! Definitely noticed it runs better than other exact laptops I’ve seen and I think this must be why!
I just got my legion 5 pro with 32 GB RAM (ordered in Germany) and my original memory has exactly the same timings as your upgraded memory. It seems that this is not a problem for all models.
Really superb videos. Sometimes I find the speed of speech delivery a fraction too fast, but really excellent in depth work and production. Congratulations and thanks to Jarrod.
Great work jarrod! I never expected similar memory to perform so different from each other, this raises a question How many more laptops can benefit from better memory since we don't know what kind of memory other OEMs have put in their laptops
@Jarrod’sTech thank you for making this video! I ordered the Legion 7 with an RTX 3070 and AMD R7 5800H. I opened it up to check the memory and surely enough mine came with the 1rx16 memory. So I was able to switch it with better memory for a performance boost.
I have the same laptop with 32GB RAM instead of 16 you use in this video. I also did the benchmarks of Shadow of The Tomb Raider, Farcry 5 and Battlefield 5 and got the same results you got with the new RAM. So there might be an issue in the 16GB configuration. Also here are the results from the ZenTimings software: tRRDS: 4, tRRDL: 8, tFAW: 34, tRFC(ns): 550, tRFC: 880, tRFC2: 560, tRFC4: 416, tSTAG: 9. I hope someone finds this information helpful.
I also tested Shadow of the Tomb Raider. I got 122 FPS in shadow of the tomb raider with stock RAM (32Gb) so also same as the better RAM. A shame that Jarrod makes it sound like the 32Gb version also suffers from the same performance loss. I've read a few comments of people with 32Gb RAM buying new memory for no reason because of this video.
Just received my Legion 7 with the 3080 and the 5800h this had exactly the same slower ram as you have reported. This laptop was bought in the UK. Update I replaced the memory with the CT2K16G4SFRA32A kit timings are exactly the same as your new memory. Thanks for the tip.
I updated my Aorus 15P XC 10th gen with 3070 from 16GB (2x8 1rx16 ) to 32GB (2x16 2rx8) and the uplift in FPS (11 games tested) is on avg 9.42%. The biggest gain came with Horizon Zero Dawn at around 13%. So it works :)
That explains a lot. I immediately swapped out my ram for 2 32gb sticks when I bought my legion 5 pro so I never noticed it was being bottlenecked by the memory. That's very informative.
@@How-IT-Do My 32Gb model got 122 FPS in shadows of the tomb raider, the best laptop on the list got 123 FPS. So I don't think you need to upgrade RAM on the 32 Gb model. For some strange reason the 32Gb model does perform better. (I've been spamming this everywhere after testing, lol). But no need to waste your money, unless you need more than 32Gb.
@@atnfn one thing to note is that having more ram increases gaming performance, especially on ryzen laptops, so you still might get better results with new and better memory than the stock ram but as you said it’s already performing great so no need to waste money. Also thank you for spreading the message
Upgraded to 32Gb of Timetec RAM. It's weird as it's definitely faster than the Samsung with the same TRFcs. All other values seen at 2:34 are faster (like 30% lower on avg). Passmark's Memory Mark gave me a 51% for the Samsung sticks where as the Timetec bumps it up tp 65%. So I think I'll settle with the Timetec for now. Crucial's stocks seem a bit low in Canada.
Makes me wonder if the better memory SKU was intentionally used in the legion 7 to create greater differentiation between the performance of the similarly speccd models. I'm not a laptop guy but considering it for the future... Is there no advance overclocking options for memory on laptops for things like sub timings?
Hello, thank you for (probably) being the first one to point out that potential problem, Jarrod! :) I'm currently located in Germany, got my Legion 5 Pro via campuspoint and my stock ram appears to have the same specs as the new ram you tested. Frame times look fine as well (more or less). Hope that might help some of you :)
When it usually comes to laptop memory, its important to note that all 32GB are always dual rank at 3200MT/s. So its never worth it upgrading 32GB laptops to some "faster" memory because they wont be faster even if you go from CL22 to CL18 JEDEC, difference is minimal, but if your laptop supports XMP configuration then SO-DIMM CL14 3200MT/s memory does in fact exist.
Great video! I got my Legion 5 Pro just 4 days ago. Can't Lenovo maybe fix this issue with an update or so? Because changing RAMs and paying 180 € extra defeats the purpose of this laptop being reasonably priced!!! Did Lenovo comment on this mysterious issue?
I'm still getting this with stock memory sticks, and maybe swapping them out later. A 10 fps difference for me is not that big of a deal when we're already getting around 120fps. A laptop has other benefits than just getting the highest fps. Anyway thank you so much Jarrod!
@@hectorgomez401 That 1% lows is just 1% of the time of that particular benchmark test. The other 99% of the time, game performs quite well. For example, let's say the max fps you get is 300 fps. Sounds great? Every 2 seconds, there is a dip to 20 fps. So, the min fps is 20, and max is 300. The average could still be very high, sounds really good but it isn't. 1% low is telling us that the worst 1% of the time, the game gets 112 fps. It really won't matter at High FPS. Maybe matters for an Esports gamer.
@@aryank3014 Improving 1% lows is much more important then improving overall average FPS because 1% lows are the big drops that feel like stuttering when you play, so boosting them gives smoother gameplay.
As did I, just went to Microcenter and bought the Legion 5 (non-Pro) with the 3060 and 1TB SSD ($1,299 USD), it has 16 GB and I planned to upgrade to 32 GB anyway so the RAM timings issue I found via these videos when researching the laptop was a non-issue for me since I know I will only be living with it for a short time until I can do the RAM upgrade.
@@mingyi456 The 32Gb model does not suffer from this performance loss, I tested it myself got 122 FPS in shadows of the tomb raider at 1080p high, higher than Jarrod's 111FPS.
Thanks for this info, I appreciate it. Do you think Legion 5 (non-pro version) has the same problem? I bought the 17 inch version. At this point I'm fine but one day when I start noticing slowdowns, I know RAM is worthy of an upgrade.
For what it's worth - I purchased the Lenovo Legion 5 Pro 32gb/3070 from Lenovo Australia, and the timings in ZenTimings is showing the same was your 'My New Memory' @ 2:32 - So it doesn't appear to be an issue anymore/with Australian variants. Copped it for
2 ปีที่แล้ว
Hello can you send here your Lenovo Legion 5 PRO producent code? For example 82JD00EAPB.
Just to put some more information out there, I just bought the Legion 7 with a Ryzen 5800H, two terabytes of memory, a RTX 3070, and 32 gigs of RAM for a little over 2k. This machine is a beast for one thing and has a beautiful display. Getting to the point, the 32 gigs of RAM in mine are identical to the new sticks (faster ones) that you put in the Legion 5 Pro this episode. Ive seen some folks saying the Legion 7 also has the slower memory and I'm thinking that could be true, for models with less than 32 gigs. Just something I wanted to know before I ordered but couldn't find any information on it.
@@woomygamer642 I think the performance is fantastic. I mean, you wont get current gen Desktop performance out of it of course, but its still really really good IMO.
Got my 82JQCTO1WW model today, which is the Stingray white version. Spec: 32GB 5600 3060 1TB SSD. I tested the ram it shipped with and all timings are the same as Jerrod's good ram. Very happy. The white version is really nice, so pleased I took a gamble on that since nobody seems to have one for video review beforehand.
Can I say that the memory problem is fixed? It's because it is. It was an issue with the first release of the Legion 5 Pro. Now the memory has decent secondary timings.
Question: Can I still get the max performance, if I use both the stock ram and new ram together, or do you need to replace the old ram with the new ram completely.
if you mix RAM the best case scenario is you run at the slower timings, worst case it won't boot and middle of the road case it runs at like 2133 Mhz's instead of 3200 Mhz.
@@Zentrious i have the l5pro and if you were wondering I have the same results as the new ram in the video with my stock ram. So either i was lucky or they fixed the ram problems.
Its true :-) The 1Rx16 modules have significantly lower bandwidth compared to the 1Rx8 variants. The more bank groups a memory module has, the higher the bandwidth is. Contrary to what the naming convention may suggest, the single rank x8 modules have twice as many bank groups compared to the single rank x16 variants.
He showed some people got the stock 32 GB RAM Lenovo sticks with same lower spec tRFC so I think it's not that easy to give you suggestion on that. Probably the one shown @4:25 on the right should be fine: P/N KHX3200C20S4 I guess.
I went 2x16 dual rank hyperX impact. They are cl20 jedec spec so a little tighter timings. Any faster ram (cl18) wont help as that is xmp profile, and not supported.
@@SYmotgang last I checked, Lenovo used insyde bios for their gaming laptops. Unlocking the full range of options only requires modifying some firmware EC bits, a lot of guys on bios modding forums do it, quite easy.
For anyone who reads this. I recently purchased a Legion 7 (2021) and it also has the slow memory (the one shown here for the Legion 5 Pro). My Legion 7 is configured with a Ryzen 7 5800H, 32GB RAM & 3070. So just to put it out there, I think the difference is not related to the model "Legion 5 Pro" or "Legion 7", but more having to do with the chosen CPU (5900HX vs 5800H). Now, not all of the timings are the same, some are lower, but tRFC (ns), tRFC, tRFC2 & tRFC4 are the same as the slower one.
I tested my 32Gb model in shadows of the tomb raider at 1080p High. I got 122 FPS. (Jarrod got 111 FPS, the best 3070 laptop on the list got 123 FPS) For whatever reason the 32Gb model does perform better. I was sceptical when I heard people say the 32Gb model performs better, so I had to test it myself. I've watched reviews before and having 32Gb rather than 16Gb never makes any difference. But somehow in this laptop it does. Perhaps the 2x16Gb models have more chips on them I guess and that somehow improves things. I have no idea. All I know it seems what people say that the 32Gb model performs better is true.
@@atnfn hope you are right..I just ordered 32gb version last week. If only Jarrod post this earlier, I would bought 8 gb ram stock and buy two newer and better ram which would save me money 💰💰
@@nuraizayoi3319 Well I'm half right. I tested with wrong settings, high instead of highest. There actually is a performance loss on the 32gb model as well. But it isn't as big, on highest I got 118fps. Better than 111fps on the 16gb model, but not as good as with better ram. Unless when he said highest he actually meant with all settings maxed. Cause the highest preset doesn't actually max all settings. But I think the performance drop is way too big if you max all settings, so I don't think he meant that.
Did some digging on this. From the Video, looks like the Legion 5 Pro has 4 chips baked in the module, 2GB each whereas the Crucial Module has 8 chips which means each of them has 1GB of memory. I think the performance difference is coming due to Memory Bank configuration (not to be confused with Memory Rank). Normally each of those chips are divided to multiple Banks and some of the banks from each chip makes a Bank group for the whole DIMM. This increased the parallel read and write capacity in the DRAM chip as Memory controller can access one row for each Bank Group parallelly. So, if a memory has more number of Bank Groups, with each group having less number of banks, the parallel read and write capacity increases. From those two memories, it looks like that the Crucial Memory having more number of chips (8GB is divided into 8 one GB chip vs 4 two GB chips in original Ram) and high chance that it has more number of Rank Groups. I have also checked Crucial official site and they mentioned to have 1024MB Chip size.
@@markmichaels5835 just bought it yesterday, I'm interested as well. I'm waiting to buy a new RAM as I want to test it first, some regions are lucky and got a better one, I live in Italy. Tomorrow it'll get here and I'll know what to do.
@@lambdacode1503 I did some digging and found the HX432s20IB2K2/32 by hyper impact, increased performance by 13% and its 32. Might be worth a look. I already put an order in so I can report back.
Appreciate your work - great investigation! I just received my Legion 5pro 3070/32GB and so far it is a great machine especially the display. Gonna test it with some games today,
On my 32GB Ram model i have combinations of both timings from your two different memory, tRFC from your stock, but every other timing from your new memory. Wierd
If you look at some photos, seems like the 2021 legion 5 (non pro) has last year's ColdFront 2.0 thermal system. Which makes me wonder how it will handle the optional 3070 gpu
@@azuraligthfeilt is it gonna be that bad in terms of thermals? If so the 1660ti or 2060 are better options? Sorry it's my first time to buy a laptop so i just want to be sure 😅
@@ciscasaclang3378 I'm not sure. So far, I haven't find any Legion 5 2021 review that has enough detail to give a comprehensive and objective conclusion. Last year's Legion 5 seems to handle 2060 well. I'm confident that the Legion 5 2021 will be able to handle 3060 just fine. But, I can't say for sure with the 3070. If I remember correctly, Lenovo did set the 3070 on Legion 5 (non-pro) to 130W which givez us hope that the CF 2.0 system *might* be able to handle the 3070 with formidable performance and minimum throttling. But, I honestly can't say 100% for sure.
I guess only you are that kind of a person to question, analyse and try to solve.... I've just bought Legion 5 Pro and I will definitely try this out, thanks!
This could've been fixed to some degree if they provided the option to tighten the timings in the BIOS like some other OEMs (MSI, sweaty laptop brands, etc)
IIRC no AMD Cezane laptop has RAM timings editable in their BIOS. I have a Tongfang laptop: Intel variant do have the timings, but AMD variant of the exact same model has not (presumably as the Zen3 Integrated Memory Controller forbids any change). The examples you provide are likely Intel variants..
somehow i doubt it, as it would make the other models perform worse than similar specced laptops from other vendors. I guess thay got a really good price on that OEM samsung ram and just went for it.
3 years after I purchased this laptop, I will attempt to replace the 1Rx8 SK Hynix RAM that it came with. Thanks for discovering this in the first place. I'm still very satisfied with the laptop
Interesting findings. I installed that software on my Legion 5 (from last year with 4800H and 1660 Ti) and the timings are exactly the same as the ones from the second memory kit you installed (the better one). The entire first two columns are identical. And these are the stock 2x8GB sticks that came with it. Thaiphoon Burner shows it's made by Ramaxel, and with Micron chips, same as yours and also 16 banks. I wonder if last years Legion 5 also had the same RAM timings discrepancy according to RAM supplier.
Thanks so much for this video Jarrod. I was wondering why my unit wasn't performing as fast as other brands. I'm from the UK and can confirm I have the same ZenTimings results as your default
@@JarrodsTech What would you think? The 32GB original RAM or 16GB new RAM with improved properties. What brings more performance. And do you think the increase in performance with the 32GB variant is as high as with the 16GB variant, if you use the better RAM? Thanks for short answer. ..
Impressive testing and follow up! I wish more notebookproducers would give users access to ram-tweaking. On my old clevo P651 (i7 6700hq and 1070) I had full access and overclocked the stock ram from 2133cl15 to 2400cl14 and lowered tRFC and a few others. 5-15% higher fps depending on game/setting. Holding ctrl+f while booting reset bios to default if I tweaked too far.
Just checked my one month old L5 pro RTX3060 32GB and stock it already has got the memory with the faster timing, just like in your "New RAM" table. (tRFC 350ns, tRFC 560) Really happy with it, it's a great laptop for my CAD/CAM purposes!
Appreciate this effort Jarrod , I am really delighted that you took the initiative and the effort. Keep up the good work man. Someday soon you'd have the wider recognition and praise you deserve.

One of the big reasons the performance is so different between these two memory kits is exactly the 1Rx8 vs 1Rx16 nature of the kits. This in particular relates to the bank group architecture used in DDR4. The short answer is that by only using 4 chips, each chip needs to provide 16 bits of data rather than 8, this reduces the amount of parallelism that is available within each chip and thereby driving up the latency of consecutive accesses. The longer timings certainly don't help, but they don't make all the difference.
The long answer is that when running in x16 mode DDR4 chips normally run with 2 bank groups, this is in contrast to the 4 bank groups when operating in x4 or x8 mode. Bank groups allow DDR4 to increase parallelism by having multiple independent sets of banks muxed together. By ping ponging between the different banks on consecutive accesses the memory will use the tRRD_S timing, when accessing the same bank group, tRRD_L needs to be used. Having 4 bank groups gives you a 75% chance of being able to hit a different bank group whereas 2 bank groups only allows for 50% chance, sustaining long strings of RRD_S hits is even more in favour of the 4 bank group setup. For example: An access pattern BG0 BG1 BG3 BG1 BG2 BG3 would only hit RRD_S, there are many other possible access patterns of the bank groups that will only hit RRD_S, on the other hand the only access pattern that will exclusively hit RRD_S on 2 bank groups is BG0 BG1 BG0 BG1... It is also easier in terms of data mapping with potentially branching access patterns to guarantee hitting a different bank group on the next access.

Thanks for the thorough explanation! Quick question: if you pause the video at 2:52, you can see that both the x8 and x16 RAM sticks have 4 chips... or is the x8 stick dual-sided and hold another 4 chips on its hidden side?
This channel deserves millions of subscribers. I learned so much and I am so impressed with the presentation and how analytical and well-thought out everything is!!! Thank you!
It's because of different bank groups of RAM. 2BG and 4BG, Ryzen runs a lot better on 4BG. You can check your RAM's model by software such as AIDA64, or MemTest 64. For Legion 5 pro. two models of RAM were used: M471A1G44AB0-CWE is of 2BG, and M471A1K43DB1-CWE is of 4BG.
To explain this, you need to understand that a “memory rank” is a 64-bit row of memory chips on a memory module. 2R = two memory ranks per module. 1R = one memory rank per module. 2R memory is often called “dual sided”, as the chips for the different ranks are usually put on opposite faces of the module.
Dual rank memory (e.g. 2Rx16) has lower latency than single rank memory, because the memory ranks can be accessed independently. Because RAM needs to regularly be refreshed, and all the data in a rank refreshes at the same time, having two memory ranks allows data to be written or read from one of the ranks while the other rank of the channel is refreshing, which means the CPU doesn’t need to wait for the memory to complete its refresh before writing data, as it can switch to the other rank. This way of switching between ranks between refreshes is called “interleaving”.
Interleaving reduces latency and improves memory performance, but it also puts additional stress on the CPU’s integrated memory controller, which has to directly manage the interleaving process. Because of this, some older CPUs with weak memory controllers cannot run dual rank memory at the same frequency as single rank. There is a trade off between frequency and latency when choosing between dual-rank and single-rank memory.
For modern CPUs (e.g. Ryzen 3000-series and newer, Intel 8th gen and newer) dual rank memory is usually best, as these CPUs can easily manage interleaving for dual-rank memory at high speeds (4000MHz+).
If you have a motherboard with 4 memory slots, memory ranks can be interleaved between separate modules - for example, if you install 4 single-rank memory modules, you will have two channels with 2 memory ranks each, and you will get the same performance benefits as with 2 dual-rank modules. You can run triple-rank by using two 1R modules and two 2R modules, or quad-rank using four 2R modules, though the performance benefits from going above 2 ranks per channel is minimal, and it puts additional stress on the memory controller.
The x8 or x16 refers to the bus width of the individual memory chips, and is related to the arrangement of the internal memory banks. As each rank is 64 bits, a 1Rx8 memory module will have 64/8=8 memory chips on it, and a 1Rx16 memory module will have 64/16=4 memory chips on it. Modules using x16 chips are usually cheaper but almost always slower than those using x8, due to having fewer banks, which effectively increases latency and reduces bandwidth because accessing data in different banks is faster than accessing data in the same bank, and also due to the use of higher-density nodes with lower manufacturing costs but worse stability at low latencies and high clock speeds.

This is awesome. Definitely what I subscribed for. Hopefully people will be able to solve this issue.
Hi there! Really appreciate your video. You mentioned in the video that you weren't sure whether the performance increase was related more to the extended timings vs. the upgrade to 1rx8. I can confirm that it's almost entirely from the 1x8.
Got a new Lenovo Legion 5 Pro with low tRFC 1rx16 memory (HMAA1GS6CJR6N-XN). Nearly a 10% CPU bench performance increase when upgrading to 1rx8 with identical timings (only difference was CL 22 -> 20).
That's a very advanced explanation !
Big Salute Jerrod you're pure👏
Cheers for discovering this Jarod!
I tried grid autosport was getting average of 100fps and minimum of 72fps. Upgraded to some Kingston hyperX and my average FPS was 115fps and lows of 95fps
Your reviews are so interesting! I bought myself a legion 5 from 2020 after looking at ur video a couple times last year
My Legion 5 arrived yesterday, il be swapping out the RAM and getting the performance boost thanks to you. Just another reason why im now a patron. Your the best laptop reviewer there is.
Well, check ram before you actualy do it. Because I have legion 5 PRO too and my test shows same numbers as he has with new ram.

I know this is a year old, but just got a L5pro on the cheap and yeah, huge boost in min FPS after I followed the advice here and got some 2rx8 RAM. Thanks mate.
Thanks Jared for the thorough investigation on this. Never seen changing memory kit for laptop with same speed and latency bringing that much performance difference. May be a deliberate attempt by Lenovo to downplay Legion 5 series compared to 7 series. Would you be checking this for the Omen 15 as well?
Why this happening only for change the same ram?

Well it did for me. But it depends on the limiting factor. If its the GPU you wont get much more FPS by switching the RAM. If its not the GPU and you are using the slow retail RAM, iam pretty sure you will get some more FPS.

Happy I put the exact same ram upgrade in my 5p runs so good!! 2x8gb crucial perfect! Definitely noticed it runs better than other exact laptops I’ve seen and I think this must be why!

Really superb videos. Sometimes I find the speed of speech delivery a fraction too fast, but really excellent in depth work and production. Congratulations and thanks to Jarrod.
Great work jarrod!
I never expected similar memory to perform so different from each other, this raises a question

Amazing mate!! Never would've imagined that!!!
Glad we could help, Jarrod!!😊
You helped..?
@@GhostSlayerYT He is an early owner and also provided info to OwnOrDisown when the 5 pro hit the market.
@Jarrod’sTech thank you for making this video! I ordered the Legion 7 with an RTX 3070 and AMD R7 5800H. I opened it up to check the memory and surely enough mine came with the 1rx16 memory. So I was able to switch it with better memory for a performance boost.
I have the same laptop with 32GB RAM instead of 16 you use in this video. I also did the benchmarks of Shadow of The Tomb Raider, Farcry 5 and Battlefield 5 and got the same results you got with the new RAM. So there might be an issue in the 16GB configuration. Also here are the results from the ZenTimings software:
tRRDS: 4,
tRRDL: 8,
tFAW: 34,
tRFC(ns): 550,
tRFC: 880,
tRFC2: 560,
tRFC4: 416,
tSTAG: 9.
I hope someone finds this information helpful.
I also tested Shadow of the Tomb Raider. I got 122 FPS in shadow of the tomb raider with stock RAM (32Gb) so also same as the better RAM. A shame that Jarrod makes it sound like the 32Gb version also suffers from the same performance loss. I've read a few comments of people with 32Gb RAM buying new memory for no reason because of this video.
@Bevda Fucker i have the same memory and specs, i can confirm the ram is 1rx8
Just received my Legion 7 with the 3080 and the 5800h this had exactly the same slower ram as you have reported. This laptop was bought in the UK.
Update I replaced the memory with the CT2K16G4SFRA32A kit timings are exactly the same as your new memory. Thanks for the tip.
I updated my Aorus 15P XC 10th gen with 3070 from 16GB (2x8 1rx16 ) to 32GB (2x16 2rx8) and the uplift in FPS (11 games tested) is on avg 9.42%. The biggest gain came with Horizon Zero Dawn at around 13%. So it works :)
Can you provide me with a link to that ram
Can ask for the serial number of Rams? I still confused to buy single rank or duel rank.

Just letting you know guys that I just got my 2021 Legion 7 with the 3070, and it has the slower samsung RAM. So it affects Legion 7s too.
Upgraded to 32Gb of Timetec RAM. It's weird as it's definitely faster than the Samsung with the same TRFcs. All other values seen at 2:34 are faster (like 30% lower on avg). Passmark's Memory Mark gave me a 51% for the Samsung sticks where as the Timetec bumps it up tp 65%. So I think I'll settle with the Timetec for now. Crucial's stocks seem a bit low in Canada.

Makes me wonder if the better memory SKU was intentionally used in the legion 7 to create greater differentiation between the performance of the similarly speccd models.
I'm not a laptop guy but considering it for the future... Is there no advance overclocking options for memory on laptops for things like sub timings?
Pretty sure the legion 7 suffers from the same ram issue
Hello, thank you for (probably) being the first one to point out that potential problem, Jarrod! :) I'm currently located in Germany, got my Legion 5 Pro via campuspoint and my stock ram appears to have the same specs as the new ram you tested. Frame times look fine as well (more or less). Hope that might help some of you :)
This dude is f-k-i-n amazing. I wish you were in millions
Damn. Very well done Jarrod. Great job finding the problem and showing us all how to get this machine optimized.
When it usually comes to laptop memory, its important to note that all 32GB are always dual rank at 3200MT/s.
So its never worth it upgrading 32GB laptops to some "faster" memory because they wont be faster even if you go from CL22 to CL18 JEDEC, difference is minimal, but if your laptop supports XMP configuration then SO-DIMM CL14 3200MT/s memory does in fact exist.
Informative and quick as ALWAYS.
Great video! I got my Legion 5 Pro just 4 days ago. Can't Lenovo maybe fix this issue with an update or so? Because changing RAMs and paying 180 € extra defeats the purpose of this laptop being reasonably priced!!! Did Lenovo comment on this mysterious issue?

I'm still getting this with stock memory sticks, and maybe swapping them out later. A 10 fps difference for me is not that big of a deal when we're already getting around 120fps. A laptop has other benefits than just getting the highest fps. Anyway thank you so much Jarrod!
same here
The increase is not 10fps, it's 10% in average fps and potentially more than 10% in 1% lows.
@@hectorgomez401 That 1% lows is just 1% of the time of that particular benchmark test.
The other 99% of the time, game performs quite well.
For example, let's say the max fps you get is 300 fps. Sounds great? Every 2 seconds, there is a dip to 20 fps. So, the min fps is 20, and max is 300. The average could still be very high, sounds really good but it isn't.
1% low is telling us that the worst 1% of the time, the game gets 112 fps.
It really won't matter at High FPS. Maybe matters for an Esports gamer.
@@aryank3014 Improving 1% lows is much more important then improving overall average FPS because 1% lows are the big drops that feel like stuttering when you play, so boosting them gives smoother gameplay.
As did I, just went to Microcenter and bought the Legion 5 (non-Pro) with the 3060 and 1TB SSD ($1,299 USD), it has 16 GB and I planned to upgrade to 32 GB anyway so the RAM timings issue I found via these videos when researching the laptop was a non-issue for me since I know I will only be living with it for a short time until I can do the RAM upgrade.

Its true :-) The 1Rx16 modules have significantly lower bandwidth compared to the 1Rx8 variants. The more bank groups a memory module has, the higher the bandwidth is.

Since it's what you'll keep for the lifetime of the laptop (probably), get the best kit you can (for ddr4-3200 sodimms, I think it's CL18)
I went 2x16 dual rank hyperX impact. They are cl20 jedec spec so a little tighter timings. Any faster ram (cl18) wont help as that is xmp profile, and not supported.

For anyone who reads this. I recently purchased a Legion 7 (2021) and it also has the slow memory (the one shown here for the Legion 5 Pro). My Legion 7 is configured with a Ryzen 7 5800H, 32GB RAM & 3070. So just to put it out there, I think the difference is not related to the model "Legion 5 Pro" or "Legion 7", but more having to do with the chosen CPU (5900HX vs 5800H).
Now, not all of the timings are the same, some are lower, but tRFC (ns), tRFC, tRFC2 & tRFC4 are the same as the slower one.

I tested my 32Gb model in shadows of the tomb raider at 1080p High. I got 122 FPS. (Jarrod got 111 FPS, the best 3070 laptop on the list got 123 FPS) For whatever reason the 32Gb model does perform better. I was sceptical when I heard people say the 32Gb model performs better, so I had to test it myself. I've watched reviews before and having 32Gb rather than 16Gb never makes any difference. But somehow in this laptop it does. Perhaps the 2x16Gb models have more chips on them I guess and that somehow improves things. I have no idea.

Cause the highest preset doesn't actually max all settings. But I think the performance drop is way too big if you max all settings, so I don't think he meant that.
If your ram is 2rx8 then you are good. (16 chips per module)
Did some digging on this. From the Video, looks like the Legion 5 Pro has 4 chips baked in the module, 2GB each whereas the Crucial Module has 8 chips which means each of them has 1GB of memory. I think the performance difference is coming due to Memory Bank configuration (not to be confused with Memory Rank). Normally each of those chips are divided to multiple Banks and some of the banks from each chip makes a Bank group for the whole DIMM. This increased the parallel read and write capacity in the DRAM chip as Memory controller can access one row for each Bank Group parallelly. So, if a memory has more number of Bank Groups, with each group having less number of banks, the parallel read and write capacity increases. From those two memories, it looks like that the Crucial Memory having more number of chips (8GB is divided into 8 one GB chip vs 4 two GB chips in original Ram) and high chance that it has more number of Rank Groups. I have also checked Crucial official site and they mentioned to have 1024MB Chip size.
Imagine cheaping out on the memory to the point where performance suffers this much. How many customers did they lose to save a few dollars per unit?

This could've been fixed to some degree if they provided the option to tighten the timings in the BIOS like some other OEMs (MSI, sweaty laptop brands, etc)
IIRC no AMD Cezane laptop has RAM timings editable in their BIOS. I have a Tongfang laptop: Intel variant do have the timings, but AMD variant of the exact same model has not (presumably as the Zen3 Integrated Memory Controller forbids any change). The examples you provide are likely Intel variants..

I installed that software on my Legion 5 (from last year with 4800H and 1660 Ti) and the timings are exactly the same as the ones from the second memory kit you installed (the better one). The entire first two columns are identical. And these are the stock 2x8GB sticks that came with it. Thaiphoon Burner shows it's made by Ramaxel, and with Micron chips, same as yours and also 16 banks.
I wonder if last years Legion 5 also had the same RAM timings discrepancy according to RAM supplier.
Thanks so much for this video Jarrod. I was wondering why my unit wasn't performing as fast as other brands. I'm from the UK and can confirm I have the same ZenTimings results as your default
Glad I could help!

What would you think? The 32GB original RAM or 16GB new RAM with improved properties. What brings more performance. And do you think the increase in performance with the 32GB variant is as high as with the 16GB variant, if you use the better RAM? Thanks for short answer. ..
Very helpful in term of performance comparison thanks 👍👍
No problem 👍
Impressive testing and follow up! I wish more notebookproducers would give users access to ram-tweaking. On my old clevo P651 (i7 6700hq and 1070) I had full access and overclocked the stock ram from 2133cl15 to 2400cl14 and lowered tRFC and a few others. 5-15% higher fps depending on game/setting. Holding ctrl+f while booting reset bios to default if I tweaked too far.
Just checked my one month old L5 pro RTX3060 32GB and stock it already has got the memory with the faster timing, just like in your "New RAM" table. (tRFC 350ns, tRFC 560) Really happy with it, it's a great laptop for my CAD/CAM purposes!
Crazy follow up that shows the effort and knowledge he puts into his content. Keep it up!
Appreciate this effort Jarrod , I am really delighted that you took the initiative and the effort.
Keep up the good work man.
Someday soon you'd have the wider recognition and praise you deserve.
This was really insightful! Thank you.
