Synology NAS Memory Upgrade Guide – 2020/2021 Edition

Everything you need to know about Upgrading Synology NAS Memory

Note – This article has been updated to the 2022/2023 to factor in the new DSM, new NAS models and updates to  available memory modules

If you have purchased a new NAS Drive in the last few months, then chances are that you would use it to the best of its abilities by increasing the memory to the maximum in order to run more apps and allow more users to access the device at any time. The latest 2022 Generation of Synology NAS is still not fully established (DS1522+, RS422+, DS2422+ and DS3622xs+ so far), but the 2020 and 2021 devices are still very much available and, much like the older gen devices, all arrive with the ability to upgrade the memory to 8GB, but some users like to push this limitation, using unofficial memory from brands like crucial or Kingston, installing bigger and faster memory. Generally speaking, Synology NAS has a long-standing reputation for being underpowered when compared to brands like QNAP and Asustor, at least out of the box, choosing to focus on their award-winning DSM software. This is changing back in 2020 with the Synology drives released then featuring improved hardware choices, but still, for many, it seems a little underwhelming. One potential benefit that’s highlighted to improve performance considerably for multiple users is to upgrade the RAM (Random Access Memory) in the Synology NAS drive. Today’s post will cover my thoughts on the usefulness of upgrading the factory-installed RAM, how to determine if a RAM upgrade is needed at all and exactly how to do this. Let’s start with the latter, do you need to upgrade RAM?

Do you Need to Upgrade the Memory on your Synology NAS?

If you have bought or are considering buying a new Synology NAS and it has an accessible RAM slot (such as at the base of the device in the DS1821+ or tucked into the side of the HDD bays as found in the DS920+) slot then it is incredibly easy to buy a DDR3 or DDR4 memory module and upgrade the RAM during the initialization of the NAS. Crucial RAM is remarkably cheap these days and if you’re buying a Synology NAS model that can be upgraded, the user will almost certainly grow to benefit from the RAM. If you’ve been using the NAS for a while, you can check your memory usage using the Resource Monitor found next to all your other applications. Like most modern operating systems, Synology Disk Station Manager (DSM 6.2, DSM 7.0 or DSM 7.1 depending on your choice) will maximize memory performance so the amount of “free memory” may seem unusually small. Fear not, this is because of the way Synology have geared their OS to be as smooth as possible and DSM will keep old information in memory, for as long as possible, for faster access if it’s needed again in the near future. It can then see when you need further memory for more current concerns and then free up the memory if needed.

In order to genuinely work out if your NAS drive needs more memory, you will need to utilise your Synology device for a while and look at the Memory Monitor during a time of heavy access and usage. Make sure all the apps are running, being accessed/monitored and run all the software, media streams and backups that you normally would on a daily basis. Look at the utilization percentage, not free memory – as this will give you a much, MUCH better understanding of the memory that is required. The reason for this is that the resource monitor will exclude memory buffers and caching that DSM knows it can free up later. If the percentage is near 100%, then you will definitely, definitely need to upgrade in order to future proof as you will clearly you’ll benefit from more memory in your Synology NAS.

Synology NAS Memory Utilization Vs Available

Another cool tip (thank you OSQuest) is that you should also change the “Type” filter at the top right of the resource monitor to Swap at look at its genuine utilization. If it’s not showing 0, then you are running out of physical memory at frequent times and Synology DSM is swapping to disk which hurts performance for all applications and users. Adding more memory will avoid this and improve performance across the board!

How to Upgrade Synology NAS RAM

Let’s get down to business. First off, it is hugely important that you know that replacing the factory RAM will likely void the manufacturer’s warranty. So if you have purchased a new Synology NAS with the intent to upgrade the default memory, be sure to run it for a week or so without upgrading first to field test the NAS and make sure there are no pre-existing hardware problems. You can upgrade with OFFICIAL Synology memory, which will not invalidate your warranty, however, it is worth mentioning that Synology official memory is more expensive than the Crucial or Kingston memory counterparts. Pretty much all the Synology Desktop NAS drives are upgraded the same, so you can watch my RAM Upgrade of the Synology DS920+ NAS below:

Upgrading the memory is often very simple indeed and simply a case of powering down the device, installing the new memory modules in the NAS (as long as you have access to them), then booting up the device. It may take a little longer than before to boot, as the new memory will be initialized, but you will not need to do any software configuration and the newly installed memory should appear in the resource monitor for immediate use.

IMPORTANT!!! PLEASE READ!!!!

Although the Synology NAS memory upgrade process is very easy, it is also very easy to get wrong! It is worth remembering the following points

  • Some Synology units have the RAM soldered onto the main internal board, so upgrading these will be impossible (without careful and tricky soldering which will no doubt void the warranty. Examples of Synology NAS that cannot have memory upgrades are DS119j, DS218J, DS118 and DS115j NAS to name but a few.
  • If you are upgrading memory, it is always recommended to ‘pair’ the memory. So you should always have 2 equally sized (capacity) sticks of RAM in the slots. It is not necessarily the end of the world too, for example, mix a 2GB and 4GB Memory module (Synology themselves offer this as an official upgrade), but it is generally frowned upon.
  • It is always worth checking your CPU or internal architecture in advance on the Synology NAS, as it may well limit the maximum amount of memory you can install. Sometimes you can exceed this (i.e. the DS1520+ with its Intel J4125 CPU has an official limit of 8GB and an unofficial limit of 16GB), but if in doubt, use my free advice section on the right of this page and ask me first.

Important Considerations about Synology NAS and Unofficial Memory Upgrades

Now, let’s get serious real quick. A Synology NAS does not occupy the same importance in your hardware environment as a TV, sound system or even day-to-day PC. A NAS system will often be one of many backups of ALL your data! Therefore exercising caution on how your upgrade/tinker with it can have more dire consequences than simply breaking it – it can lead to the potential loss of genuinely irreplaceable photos, videos and more. Therefore if you are looking at upgrading the memory of your NAS drive and using hardware that is not on a recommended list by the manufacturer, you need to make sure you have your backups in order – have at least two backups (i.e 2 complete copies of your data OUTSIDE of the original file – one on your phone and one on a NAS only means ONE copy!). Additionally, if/when you install ANY new memory, it is highly recommended that you run a quick(ish) memory test using the desktop Synology Assistant application (for Windows/Mac) so that the NAS can check that the memory is good-to-go. Be warned, this process can take several hours (a relatively simple 2GB Transcend DDR4 2400Mhz SODIMM module in a DS920+ in my testing for a YouTube video took just over 1 HOUR and 40 MINUTES) and during that time, access to the NAS is largely impossible (plus the system will re-boot at least once). So ensure you do this during a quicker/downtime moment for your network. Below is a brief overview of where the Memory Test setting of Synology Assistant is and how to enable it:

So, let’s discuss 3rd party memory, Synology NAS and DSM 7.1 on some of the brand’s most popular systems for home/prosumer users – as it is these users who are less inclined to choose the official memory route.

Choosing the Right Memory for a Synology NAS Upgrade

So, you have decided to upgrade the Memory/RAM on your Synology NAS. It is worth mentioning that different NAS drives require different memory types. All too often there are factors that are as follows:

  • DDR3 – Easily the most common, this is a memory module that runs at 1600Mhz
  • DDR3L – A revision of DDR3, this memory runs at 1866Mhz
  • DDR4 – A Newer and high-frequency memory that is available to more modern CPU that runs at between 2133Mhz and 2400Mhz
  • ECC – Error Correcting Code Memory, this is a memory module that makes comparisons of data packets as they pass through the memory at the start and finish to ensure they are identical. If not, this memory will automatically heal the file and keep it moving
  • SO-DIMM – This is a smaller module of memory and traditionally found in smaller NAS that are 4/5-Bays and smaller. Generally available in upto 16GB in DDR3 and 32GB in DDR4. Larger sizes are available, but not supported in most NAS drives due to CPU memory limits. Outside of NAS, this kind of Memory is found in Laptops and portable hardware
  • LONG-DIMM / DIMM – Full-length memory modules that are twice the length of SO-DIMM, typically found in NAS devices of 8-Bay Desktop upwards, or most Rackmount NAS servers. Also available in much, MUCH bigger capacities in both DDR3 and DDR4 in NAS We are even starting to see DDR5 in large enterprise NAS servers too. Outside of NAS, this is easily the most commonly used NAS DIMM size.

Can I still use Unofficial/3rd Party Memory in DSM 7.1?

In short, yes, 3rd arty memory still works in Synology DSM 7.1. However, it also leads to DSM 7.1 displaying a warning notification in the software highlighting the use of an unsupported memory. There is also the fact that the brand might become less able to assist you in any warranty claims from reasonable system hardware failure if the issue can be stemmed in any way to memory. Now, when Synology released the latest revision of their software, DSM 7.1, there were some reports online of users stating that their system would no longer boot with 3rd party memory installed. Although I tested this on the NASCompares YouTube channel with mixed results, I have since RE-TESTED this (on the heavy request of users who did not experience any issues, who queried the results) and in that follow-up testing, ALL 3rd party memory modules worked (video embedded later in the article below). So, it looks confirmed that unofficial/3rd party memory STILL WORKS in DSM 7.1 at the time of writing, which means users still have a choice of choosing the 3rd party RAM route or sticking with the officially provided and branded memory. Below is a range of 10 different modules being tested with DSM 7.1 that was conducted in May 2022:

Is Upgrading the Memory on a Synology NAS worth it?

Many users will avoid updating default Memory on a Synology NAS server while it is still under warranty – thinking that “if it ain’t broke, don’t fix it”. However, If you are buying a Synology NAS that supports an official or unofficial user memory upgrade, there’s almost no reason not to do the upgrade. There are practically no disadvantages (none at all, if you buy official Synology Memory) and the benefits will be immediate. You can always wait till later on an upgrade when you notice a drop in performance, however, I would keep an eye on deal websites for your compatible DDR3 or DDR4 Synology NAS supported memory and then grab some when a bargain appears. I do wish some lower capacity NAS’ drives, such as the DS119j, DS218j and DS416slim (that arrive with much less memory soldered to the motherboard than their CPU can handle at maximum) were able to have their memory upgraded, as this becomes a tremendous bottleneck. There are cases where two drive bays are enough in terms of total available storage space (especially with 14TB Seagate and 16TB Toshiba NAS drives in-coming), so you will be able to run a lot of applications, for multiple users, but the rather comical 256MB, 512MB and 1GB memory available in these budget models is just not enough to run DSM to its full potential on these NAS and the result will be that most users will walk away with a very poor opinion of the Synology NAS experience.

Picking RAM

Synology lists the RAM compatible with each user-upgradeable model on their website. You can use this information to get the RAM specifications for your model Synology and then shop around for your preferred memory brand or a good price. Additionally, I have included lines to the third party crucial supported memory for a Synology NAS. Always be sure to check the compatibility before making your purchase, as Synology may have revised the hardware (see examples like the DS216+ and DS216+II).

VERY IMPORTANT – The Links used in the article below towards the correct unofficial memory are occasionally changed (beyond my control) as it will direct you to the site in your own region/country. MAKE SURE to check that the memory module (especially 16 and 32GB SODIMM modules) are DUAL RANK or ‘DR‘, as Synology NAS typically have trouble with SR/SINGLE RANK modules.

    134 thoughts on “Synology NAS Memory Upgrade Guide – 2020/2021 Edition

    1. I’ve just installed the same TimeTec 16GB RAM on my 920+ and it’s working just fine. First boot was quick (not much more than a minute for all solid green lights) and the RAM is showing in Info Centre.
      The standard 4GB at idle I’d often see the RAM use around 27% with the NAS just sitting there at idle with a few network devices attached. Now RAM use is 4% at idle so plenty of headroom. I’ll have to load it with some tasks to test it under load.
      This video gave me the confidence to do the upgrade.

    2. I installed a SAMSUNG M471A2K43CB1-CTD 16GB 2666V (made in China) into the DS220+, but it did not work. The NAS keeps flashing the blue lights for more than 20 mins. I guess not all the RAM are supported.

    3. Thank you for your great work!
      I installed a Kingston 8GB (KCP432SS8/8) into my 420+ and am pleased to report, that it is working.
      One curious observation is that the memory graph in the “Resource Monitor” is stuck at 5% utilisation while the “Memory Composition” bar more informatively shows the allocation of the 2+8GB RAM. When I copied a 20GB file from the 420+ to my laptop, the “Cached” segment went up to 8.9GB at one time. Hope that demonstrates the 420+ / Celeron could handle and make use of >8GB RAM.

    4. I upgraded my 1821+ to 7.1 today and it runs with no issues on “unofficial” 2x Crucial 32GB = 64GB ECC memory (so twice the max. oficially supported size of 2x16GB).
      REPLY ON YOUTUBE

    5. Corsair 16GB (2×8) DDR3-1600 MAC Sodimm 1.35V confirmed as working. Had to let the boot sequnce run till the green lights came on. First go, blue flashing light with both modules installed, no go, then tried old RAM and new RAM – booted fine (12GB total), then I tried my 2x8GB again, reseated a third time, rebooted, then went away and came back 20mins later and everything was up & running great! 🙂 Recognised 16GB Corsair!

    6. I use Synology 4GB DDR4 ECC Unbuffered SO-DIMM
      in my 920+. It’s recommended for RS1221RP+, RS1221+, DS1821+, DS1621+.
      I know they recommend non-EEC in the 920 but seems to work ok. Anyone know if this is ok?

    7. Have you ever tested G.Skill SO-DIMMs? Especially on a DS418Play? I’m looking at a set F3-1866C11D-16GRSL which have CL11-11-11-32 1.35v specs and wondering if it will work. They appear to be dual rank chips

    8. I have 16gb crucial in my 1819+ and it works fine. It used to say unsupported in the past but at some point it stopped giving the error. I had it since the unit came out. It’s up to date and still works great. Is it possible that if you had the ram before the update that it will bypass your do called kill switch? Or could this be more on the newer Synology units?

    9. I have the following all running 7.1 with 3rd party memory installed…rs3614xs+, rs2416+, rs18017xs+, ds2415+ and ds2419+. The ds2419+ is 1st gen and runs 32GB even though official support is 6GB – it does complain about non-Synology memory but is used 24/7 with virtual machines, camera feeds and TimeMachine without any issues. All have been upgraded from 6.x versions through to the latest 7.1 over time.

    10. I held off on updating my DS920+ due to previous video and just updated successfully after watching this video (Timetec 8G). Thanks for the follow up and all the great work you do!

    11. When I saw the title screen, I was momentarily confused because the most recent edition is only DSM 5. Then I realized what channel I was on and that this probably isn’t a video about the Diagnostic and Statistical Manual of Mental Disorders.

    12. So I bought yesterday a the Timetec 16GB Memory for my new DS720+, I have two iron wolf 8GB drives and try booting my NAS, without drive and its just stays there with the blue light blinking, left it for hours without any drive and it didnt boot. Then I have installed both drives and then installed the memory and still keep blinking for a while… how much should I wait?? Does will it actually work???

    13. Naaaah what a waste of money. Just Bought me a Timetec 16GB DRR4 76TT26NU2R8-16G. Doesn’t work on my DS720+!!!! This fellas said it was working before !!!! What a freaking shame , its doesn’t work, will see if I can ask refund to amazon

    14. Interesting! I have question about PS5 hdmi bandwidth which is 32gbps! Do you think Hardware wise Sony can uncapped the signal to 48gbps for 12bit 4.4.4? Since many people dont know to go with cheaper C1 G1 (40gbps hdmi) or C2 G2 which support 48gbps hmid bandwidth!

    15. Fantastic! Seeing this gave me the confidence to proceed with a DSM7.0.1 to DSM7.1 update on my DS920+ with 16GB Crucial memory upgrade (total 20GB).
      Success! Previous recognition was a good indicator of future recognition (within reasonable limits of probability). Ta!
      REPLY ON YOUTUBE

    16. To be fair to you, who would think that an electronic device that operates at billions of operations per second would take 15 minutes to be configured. And there is the question of why you didn’t seem to ever run into this prior to DSM 7.1. Without testing with the exact same revision that was used before there is no way to know if they updated something to mitigate the issue.
      REPLY ON YOUTUBE

    17. And this is exactly the reason why I pay close attention to Synology’s compatibility HDD/SSD lists. While everything seems to have work out fine here and the “right way” for RAM compatibility, the implications of it not having done so are very different to if that were the case for drives. For RAM you can put back the original memory and still operate, albeit in a limited capacity if you need the additional memory, especially if you’re well above the stated maximum. For drives though, the moment Synology decides that “oh we don’t do that no more” or “the compatibility list is clearly stated” can be massively problematic. One’s drives aren’t something that we can simply take out and put in something else.

      It’s all well and good that people on the internet saying things are fine but at the end of the day they’re not the ones covering your warranty nor fixing/dealing with your problem. Granted my perspective is probably skewed as I often deal with businesses. That said, I often find individuals are far more susceptible to incompatibility issues as their budgets are often more constrained.

      Memory is usually an easy fix, drives are usually not.

    18. Thanks for this update, your last video had me worried about updating DSM. I have a DS220+ which I have just updated to DSM 7.1.42661 and my 4GB Crucial memory is working perfectly. Model number CT4G4SFS8266.C8FF
      REPLY ON YOUTUBE

    19. Outstanding video mate. Very informative and one can imagine not the easiest to do. Not to criticize mind you, but it seems as if the RAM swaps were done with NAS power leads intact. It seemed to work fine if that is indeed the case but perhaps not something one would recommended to the unwashed masses,…

      Either way 2 thumbs up. Keep up the good work????????
      REPLY ON YOUTUBE

    20. I was cautiously concerned when I updated my 920+ to 7.1 as the Timetec 8GB Memory had been working. Thankfully no issues, and I ran the Synology Memory Test to be sure it was not going to throw any flags. Thanks NASC for your past advice and continued support!

    22. When I bought my two DS1815+’s, I upgraded the RAM in both to 16GB of Kingston, which is 8GB over the mfr recommended compatibility, but has worked fine all these years. I updated them both manually to DSM 7.1-42661 Update 1 today, and they both booted fine. Control Panel / Info Center shows 16GB. Running data scrubbing now, but so far, no issues. I did see that Synology states that 7.1 is the last update that will be available for the DS1815+.
      REPLY ON YOUTUBE

    23. This is simply not true, i just bought it and i tried a crucial CT16G4FRA266 in this one didn’t work since i didn’t know everyone had problems with it and didn’t know about type numbers yet, today i recieved my CT16G4SFD8266 and it basically instant worked, all on DSM7 cuz i never had any lower DSM version since i just got my system, so i can confirm this is total BS, ????????
      REPLY ON YOUTUBE

    24. I have had my 16GB stick in my 920+ (for a total of 20gb) for well over a year working fine. I was scared to update to 7.1 but I am glad to report at least on my NAS the upgrade did not effect my RAM
      REPLY ON YOUTUBE

    25. Well, that just right royally sucks. If that is the case then it looks more and more like my next NAS not being a Synology. Like any PC, I should be able to add any memory as long as it meets the minimum spces. Boo…

    26. Updated my DS416Play to DSM 7.1-42661 Update 1 today and the 8GB Patriot SODIMM I have installed (DDR3 1.35 V 1600MHz PC3-12800 CL11 PSD38G1600L2S) works just fine. No incompatibility warnings at all.

    27. Thank you for everything you do. Your thorough testing methodology leaves basically no room for misunderstanding. I’ve got a 920+ with 4+8gb of ram currently that’s been running stable for months on dsm 7.0.x. This is exactly why I disabled automatic updates. Very disheartened to see synology go in this direction. Love your videos. Keep the great content coming ????
      REPLY ON YOUTUBE

    28. @NASCompares Have you compared the additional settings (CAS, Latency, etc) for your RAM modules match or exceed the configuration of the Synology RAM modules?
      REPLY ON YOUTUBE

    29. Reading everyone’s comments. This video has had a lot of chat in the unofficial synology Facebook groups as well as r/synology.

      In over 80 comments on Reddit and even more on Facebook this video has been called out as BS as not one single comment from anyone in the above groups where people are using 3rd party RAM have had any issues with the new DSM.

      Also given in this video the time given after the reboot is no where near long enough. I have seen synology units take up to 20min after the update to reboot and come online. This also fits in with what others are saying on Facebook and Reddit.

      So I have to wonder. Why NASCompairs are putting out false and fake information?

      Is it just to get clicks on the video???

    30. I’m rocking unsupported memory (32 GB) in my 1821+ which is currently on DSM 7.0 update 3. I’m not even sure where the original memory is located, so I better find it before attempting a DSM upgrade. The recent anti-consumer moves really concern me. I really like the Synology software. I suppose as long as my NAS is doing ok on 7.0, I’ll just keep it there – at least until I can afford to pay the Sinology tax.
      REPLY ON YOUTUBE

    31. I have 64GB of Crucial memory (Crucial RAM 64GB Kit (2x32GB) DDR4 2666 MHz CL19 Laptop Memory CT2K32G4SFD8266) in my DS1821+ and it is fully recognized and utilized. I got the kit for $239.22 delivered including tax which seemed a good deal at the time. Maybe I shouldn’t bother to upgrade to 7.1? It would really pizz me off if I upgraded DSM and then my NAS wouldn’t boot. Thoughts or comments?
      REPLY ON YOUTUBE

    32. I have not had any problem yet for my upgraded timetec rams after DSM7.1. But I really don’t like Synology doing this stingy stuff to their users like they did on higher end models claimed to target professional users.
      REPLY ON YOUTUBE

    33. Yeah, it sounds like Synology doesn’t like own customers aka business. If this is the case my 1019+ is going to be the last Synology product. They believe that making crippleware will make them more money.#mistake
      REPLY ON YOUTUBE

    34. I have on a ds920+ 16gb extra. So if 7.1 would not reconize this it would be very bad. I would be very angry. I would never by the original ram. To expensive and to low memory.
      REPLY ON YOUTUBE

    35. Everyone should just build their own server instead of Synology products. They’re greedy and anti-consumer these days. Don’t fear to build it with your own and I’m pretty sure it’s worth in the long run. Recommend Supermicro’s mini server and Windows Server 2022 OS for building file server/storage server (NAS).

      P.s. @NASCompares why did you delete my original comment. Did it hurt your feeling for recommending people for another choice or is your video sponsored by Synology themself?

    36. Synology doing it Best to shut down it’s business…. I used to recommend it, but given alternative as TrueNas even Ubuntu are now fairly Easy to manage, Synology becomes unnecessary except for exotic form factor
      REPLY ON YOUTUBE

    37. This will kill Synology for any discerning home users, if they don’t fix the issue within days. (Spoiler alert, they will not.) Too bad there’s no TrueNAS/ZFS unit that comes close to the same price range for 4-5 bays. I guess I’ll have to look at Asustor or something. I’m sure not touching QNAP with their history of lax attitudes on security. If someone could get the cost of a comparable (low power draw, 4-6 bays, compact) ZFS-capable unit down to around $750-800, I think it would demolish a large segment of the home storage market for these proprietary low-end NAS devices.

    39. I own a DS213j (yes, still rocking!), a RS814+ and was considering upgrading to a RS1221+. But after following recent posts and videos about these hardware soft locks, it really make me worry about my future with Synology.. a real shame.. Here’s hoping other vendors never follow this tactic.
      REPLY ON YOUTUBE

    40. Bit the bullet and went for a DSM 6.2.4 to DSM 7.0.1 upgrade on my DS920+.
      After a successful login, Control Panel Info tab still shows 20GB RAM. Yay!
      Despite letting me download the .pat file for DSM 7.1, 6.2.4 would not let me install it directly (for incremental upgrade reasons), so I went with 7.0.1 as the lesser of two weevils/seagulls.
      I think I’ll let that settle for a couple of weeks and see if there’s any more in-depth news about what DSM7.1 has against certain RAM modules. Fingers crossed for the next round.
      REPLY ON YOUTUBE

    41. I’m getting more and more annoyed with Synology. I had a 4GB memory module from Crucial in my DS918+ working flawlessly for years. With the DSM update I started getting frequent crashes. Found a Synology supported memory and took out the old memory. It’s working perfectly again. It looks to me like they put a bomb in their code to crash the NAS when a non-supported memory module is detected. With this and the probable lack of 2.5Gbe in the 22 series, I’ll be moving to QNAP for my upcoming upgrade this year.
      REPLY ON YOUTUBE

    42. I have a 220+ with an extra 4GB Crucial stick in it, but still currently on 7.0.1 . Great machine, but what does 7.1 give the average user if I was to upgrade to it? Would it be worth it for extra features and possibly lose the 4GB , or stay on the current 7.0.1 and benefit from the extra RAM. ( I haven’t heard of anyone testing 4GB of crucial in one yet)
      REPLY ON YOUTUBE

    43. @NASCompares I have a supplementary question. Have you tried the situation where an unsupported memory configuration, e.g. 4+16GB in DS920+ on DSM6.2 fails during an upgrade to DSM7.1? Is any record of the prior memory configuration retained in non-volatile memory between boots?
      I note your tests all started with no additional memory and already had DSM7.1 installed.
      Is it possible that an upgraded installation with prior memory upgrade could behave differently?
      REPLY ON YOUTUBE

    44. Wow. The Crucial 16GB dual rank SODIMM is exactly what I have in my DS920+ working prior to a DSM 7.0 upgrade, let alone 7.1
      Initially, I was sent single rank memory, due to a vendor SKU problem, which, of course, did NOT work, once they sorted that out, it was recognised and I have 20GB RAM recognised.
      Nice to know (or not) that it may not work following a DSM 7.x upgrade.
      REPLY ON YOUTUBE

    45. I just got a 16GB stick of Crucial, am updated on the 920+, and had no problems. Had to wiggle it in and press firmly to seat fully, which was kind of a pain. But it works great with Docker and everything else. Turned off memory compression as well as it’s performing the best it ever has.
      REPLY ON YOUTUBE

    46. I have 16GB timetec working in my 918+ working in 6.9 and current 7.0. This is worrying if I upgrade and my 16GB will no longer work. I have a lot of docker containers and the 4GB standard will not cover that I need. The timetec was the 2nd try, after my initial crucial 16GB didn’t work, and sat in a draw till recently when I put it in a QNAP(running truenas) I was given that I could use that. I would hate for my timetec to become ewaste and I play the Russian roulette of trying other modules.
      If Synology offered their ram at a reasonable price, people would buy it, but their costs are on there verge of extortion.
      REPLY ON YOUTUBE

    47. Synology are just contributing to e-waste generation.
      When you upgrade the memory of a laptop you are left with a couple of sticks of small memory. A great home for them historically had been the upgrade slot of a NAS.
      Now the only place it can go is the bin… good job Synology.
      This and the Synology only HDD lockdown are pushing me out the door… they may make more money per unit but lose market share not typically the way you try to increase revenue but hey… what do I know.

    48. Synology will destroy themselves if they do this. My 1520+ is running fine on 7.01 with a dual rank crucial 16GB module. Hasn’t auto updated to 7.1 yet. If Synology bricks my system, I will burn their playhouse down.

    49. I’ve got DS920+, DS720+ and DS416Play. All have been upgraded (->20GB, ->10GB and ->8GB) and are running DSM7.1-42661 Update 1 with all of the memory available. None of the memory has been selected based on Synology recommendations but budget 🙂

    50. For what its worth both of my DS620slim units with 16GB RAM (Kingston HyperX Impact 8GB x 2 – well above the stated 6GB RAM maximum) boot and run no problem with DSM7.1 and DSM7.1 Update 1.
      REPLY ON YOUTUBE

    51. It is not a case of Synology validating RAM (the CPUs require very basic RAM) it is a case of Synology ‘Blacklisting’ any major RAM manufacturer that either does not provide the Synology ID code or is actually listed on a blacklist in DSM. This was cunningly labelled as a ‘Memory Blacklist’ in the code with all the other manufacturers named. It is a con that enables Synology to charge 3 or 4 times the price for basic Samsung RAM with a new sticker and a changed ID code.
      Blacklisting in this way is illegal in the UK. I have yet to hear from Samsung regarding their position on their RAM being sold via Synology in this way, with a new ID code burned in by them, given the prevailing laws on both competition and consumer rights.
      Regarding the logging, the memory check goes in the diagnostic log and Synology will use this as an excuse to deny warrant claims, even if the issue is clearly not related to RAM (or drives, or NICs).
      REPLY ON YOUTUBE

    52. You didn’t wait long enough for the Crucial 16Gb stick to finish booting. The first boot with new memory installed always takes a while. I’m running that exact same Crucial RAM in a 220+ (18Gb total) under 7.1 with no issues and no “Incompatible RAM” warning. Note that it’s essential to use “Dual Rank” RAM in Synologys. Single rank often will not work.

    53. Crucial 2666 MT/s SODIMMS CT8G4SFRA266 DDR4 Memory, Green 8 GB works fine on my DS920+ and DSM 7.1-42661 Update 1. I’ve had it running since late december 2021 and always with DSM 7.
      REPLY ON YOUTUBE

    54. The Arche branded 16GB DDR4 I purchased with my RS1221+ is still moving along no issues. When buying RAM from Synology NAS I tend to look for a brand that says its tested specifically for Synology. May cost a bit more than others but definitely less than Synology branded and hasn’t failed yet.
      REPLY ON YOUTUBE

    55. This sucks. Was planning to buy Synology just to replace Google photos with simple to use solution for our whole family but their anti-consumer attitude is sickening. Purposefully blocking ram upgrades with firmware/software and forcing enterprise user to use their own branded HHD’s, like what?! It’s almost as if car makers would force you to use only tires that are their own brand just because “it’s not safe to use any other brand”… ????
      REPLY ON YOUTUBE

    56. running DSM 7.1-42661 updaet 1. still got my Crucial 16GB running without issue, nor I got any notifcation for unsupported ram. I personally dont mind buying supported ram/harddrive. I can see the benefit to have a throughtly tested ram/harddrive as it rule out some unknown factor for troubleshooting. but the current price tag of rebranded product (ram/harddrive) is just … too heavy for the normal consumer.
      REPLY ON YOUTUBE

    57. For me this kind of blocking isn’t a good way. Synology should give only guarantee with their own memory and allow to use what ever we want – without guarantee. So it would be up to each user to decide what to do. But this restrictions are bad for the company reputation. Ja, they might not care about as they selling so many systems… but if you have a bad taste in your mouth, it’s hard to get rid of it. Thanks for that good video. Take care. Stephan

    58. Hmm, that’s discouraging. But I did just recently upgrade my ds1821+ to 32gb and didn’t even get any warnings, it’s working just fine. My ds2419+ has 32gb also, it initially gave one warning about unsupported ram and that was all… it’s been running for 2 years like that. Both are fully upgraded to 7.1.

    59. Looks like I’ve been lucky – DS920+ with 16G added in Dec 21 and still works fine after ugprade to 7.1
      I ‘get’ that its not supported, but if helps anyone, I’m using ‘Crucial RAM CT16G4SFRA266 16GB DDR4 2666MHz CL19 Laptop Memory’

    60. Thankfully I couldn’t buy a NAS yet, so now I know a little better what brands to skip. Unfortunate that I’ll have to start my research from zero again

    61. hi, so I was right, tested on 220+ and 1821+, Crucial and Kingston on DSM 7.1- its soft lock by Synology. We can use 7.01 only, after that its bricked. I have no words for this. Anyway, tx for confirming my testing in your video. I appreciate your work.

    62. DS920+ with Kingston 16GB(1x16GB) DDR4 2666MHz SO-Di (manufacture code KCP426SD8/16) and DSM 7.1-42550 still works like a charm. Although it tells me that I’m using non recommended modules. Have rebooted several times without any issues. Had this module also with DSM 6

    63. I feel like if Synology could, they would start branding HDD’s the same way they do memory and just force people into that. I’m already surprised they don’t do this with NVMe drives. The reality is, if the platform you built is THAT unstable that a RAM module can completely tank it, maybe rethink your architecture? Other companies sure have figured it out.

    64. Yeah, I have a DS418play and have come to regret it more and more. It was a good “baby’s first nas” but the anti-consumer practices are really getting to be too much.

    65. I am a basic NAS user (backup and media home sharing)… own a Synology DS1817+… works fine… but I don’t see myself buying any more Synology devices. Locking me to their HDD and Memory is just no acceptable.

      I also have a QNAP… and will keep using QNAP or move to building my own NAS with TrueNAS.

      Stupid move Synology!

    66. This is terrible news and I hope Synology fix this situation ASAP, because pricing and general availability for Synology RAM is insane.

      One example for the DS220+, a 4GB Synology DDR4 stick (D4NESO-2666-4G) is $169 in Australia (US$119) vs the 4GB Crucial DDR4 stick $38 (US$27) CT4G4SFS8266 from the same seller.

      If Synology sold their RAM for 25% more than the same product from Crucial instead of 340% more, then of course I’d buy it and not even think about it.

    67. Synology is just trying to destroy their own business being greedy. There’s no technical reason for this policy as they use standard components like memory and hard drives. When it comes to upgrade my NAS or recommending to others I’ll look for a different solution. Thanks a lot for this video.

    68. I have two of these in my DS1821+ Samsung 16GB M474A2K43BB1-CTD DDR4-2666 ECC SODIMM 2Rx8 OEM Compatible Memory I will wait to upgrade to 7.1
      REPLY ON YOUTUBE

    69. without any experiments or testing: just add unofficial RAM similar in spec to official synology sticks. Official synology ddr4 sticks manufactured by samsung with 2666mhz speed and CL19 latency. Intel J4025/4125 cpus dont support more than 8GB anyway. Thank me later?

    70. one of the motivation i’ve always used qnap… can’t understand those decisions from synology to be honest, and i can’t understand how people are comfortable to be that controllable and install ONLY their memories
      REPLY ON YOUTUBE

    71. Great test… it’s really unfortunate that Synology is enforcing these policies. They seem purely arbitrary and not based on the what the technology is capable of. It’s starting to seem like a pattern with them. It’s definitely putting my future with Synology in doubt… which is unfortunate.

    72. 2 minutes into the video I’m thinking. What i you have a model that has no soldered on memory? I have a ds1821+ on 7.1 and the Kingston 2 x 16gb ECC works no problem. BUT I do get a notification that there is unofficial ram installed. So I’m thinking, if you have a model that has no soldered memory by default it will have to use the unofficial ram to even get to the point to boot the system and see the ram is not officially supported. Or am I wrong?

      Also, check out if you can spoof the memory serial numbers. I think there might be a hack worth investigating here.

      Also I think that this is something Synology should NOT be doing. It’s like buying a Mercedes car and if you don’t use their mercedes brand Oil (which is the same as any other w213 oil for example) the car just won’t start? Heck no. This is BS. I would understand not honoring warranty or that you get a notification, but just killing a setup like thisi is NOT RIGHT! We’ll see what happens when Synology gets a taste of a bunch of people like Louis Rossmann. I would also start investigating how to get some lawmen involved into this, because this really is walking the line. I understand if you’d buy a new device and it was CLEARLY said that ONLY that WILL work. But they specifically mention just warranty and technical support for DS1821+ for example. Like I said, NOTIFICATION is fine, COCKBLOCKING IS NOT FINE! Especially 1 year later with a software update that is specifically made to do just that (among other things)! To Cockblock you.

    73. I ordered a 16GB Crucial CT16G4SFRA266 module bit that seemed DOA. My DS1520+ )with DSM7) wouldn’t even power on. Tried it in my XPS laptop and that also didn’t boot.

      Tried one Kingston KHX2933C17S4/32G module of a 32GB set and that worked without problems.

      1. I can tell you that Synology only gets along with the Crucials in my opinion, but then it also depends on the model of the memory chip.
        Use Amazon so if it doesn’t work, return it… 😉
        Ciao… 😉

    74. I got a 16GB Crucial CT16G4SFD8266 for € 75 and it works perfectly on my DS220 + (as does others).
      In my opinion it is a problem with the card model.
      I have DSM 7.0.

    75. Tried to upgrade my DS420+ with 16 GB Kingston kcp426sd8/16 (witch worked for others) and I got the blinking blue light for 1.5 hours. It may be DSM 7’s fault? I planned to have a VM, but that is on hold for now…
      Maybe you could revisit the RAM upgrades tests for DSM 7…
      Thanks.

    76. I just mounted on the DS220 + which I took 2x IronWolf PRO 8TB ST8000NE001 and 1x Corsair CMSX16GX4M1A2666C18 16GB.
      The blue led is flashing and I have not heard any error beeps (I don’t know if Synology gives error beeps like a PC …).
      How long does the blue LED flash?
      How do I notice that it has left, do I notice it because I reach it via the network?

    77. Bought Kingston 8GB which seems NOT to work with DS220+. Memory exact type 8 GB SO-DIMM 2666MHz DDR4 (KCP426SS6/8). Tested with and without extra memory few times. Without extra memory DS220+ boots in about 2 minutes. With extra memory I waited both test times 20 minutes and blue led just keeps blinking.

      1. Bought today a new module with 4 GB capacity. Exact model KCP426SS6/4. Specifications otherwise similar to previous but size 4 GB instead of 8 GB. This works perfectly.
        Still Synology reminded me with a warning email ”Detected non-Synology memory module. Please refer to our official website and select authentic Synology memory modules for better system reliability.”

    78. Hello,

      I just received a DS920+ and a 16 GB Crucial memory module referenced here. I place it in the DS920+ and nothing seems to happen, just a blue blinking light. I remove it and the DS920+ boots up fine. Is there something else I need to do to get the memory to be recognized?

      Thank you,

      Bret

    79. Hello,
      do you know when the DS720+ (and other 20’s models) are going to be released?
      Is the COVID-19 pandemic affecting the releases date?
      Thanks
