Synology Unofficial Memory Upgrades – 2023/2024 UPDATED

Everything you need to know about Upgrading Synology NAS Memory

Note – This article has been updated to the 22023/2024 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 (DS923+, 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.

      1. If you replace the memory with an unofficial stick, you apparently void your warranty. Does the NAS remember that it had unofficial memory in it, if you swapped back in the official stick while still in warranty?

      2. Thks Robbie,
        *For over a year it’s been the !DS1824+ or Bust!
        *However you finally tempted me one too many times.
        *The optimal (really least-worst) NAS for me is surprisingly the DS423+.
        *In a nutshell: DS423+ $500 4bays for RAID5 (>1.9Gb/s data xfr speed) ; NMVeSSDs (>1.6Gb/s quick boost cache) ; & upto6/18RAM
        *Plus I’ll connect a 8bay HDD/SSD USB3.0 enclosure $250 to it.
        *Total cost w/o HDDs is just ~$600.
        *If I ever need super high data xfr speeds for super large files ; I’ll attach a 4bay HDD/SSD thunderbolt3 external enclosure to my computer via software RAID-for-Speed & make the RAID-for-Speed into a Synology Drive.
        *Wish me luck

      3. Hi I bought the 923+ and it have Synology RAM D4ES02-4G – 4GB DDR4 3200 ECC . Do you have info about compatible 16GB RAM ECC ( I insert Kingston KTL-TN432E/16G and is a warning message regarding RAM )
        REPLY ON YOUTUBE

      4. Strange, i use a 4gb ddr4 2666mhz cruxial module. Although it has the same specs like the synology one it is unsupported, but i dont get this warning.
        REPLY ON YOUTUBE

      5. But on the product page of synology ds220+ there is written that only 4 gb ddr4 sodimm non ecc ram is suported. But synology has only ecc ram?????
        REPLY ON YOUTUBE

      6. Tried the Sabrent 8gb module, it worked for about a day then I got all solid blue lights and it didn’t respond again, unplugged, never started, removed hard drives, never started. removed memory, everything worked fine. plugged it back in, didn’t boot. so either I have a bad chip or it’s not compatible. I don’t have another way to test this chip so I’ll test another one.

      7. Synology DS220+ won’t start with Crucial SODIMM DDR4 16Gb 2666Mhz CT16G4SFD8266.C16FJ
        Blinking blue light and that’s all.
        I have DSM 7.2-64570 Update 1
        REPLY ON YOUTUBE

      8. As an electronics engineer for many years I am appalled whenever I see Robbie handling memory modules without any electrostatic protection – a recipe for disaster!!
        REPLY ON YOUTUBE

      9. The prices of Synology branded memory and drives are absolutely insane. I would understand if the price was like 5%-10% more than other brands but that is not the case. Also the specifications of many Synology NAS models are lacking compred to Asustor or QNAP, especially Synology continuing to use 1GbE on so many of their models when 2.5GbE should be the absolute minimum.

        As a first time NAS buyer this practice by Synology has me considering other brands which is a shame because the DSM software seems really nice.
        REPLY ON YOUTUBE

      10. Crucial works fine in all 7 of my synology devices on 7.2. Both desktop and rack systems. However, I respect the limits pointed out by Synology as well and don’t exceed what they state.
        REPLY ON YOUTUBE

      11. Is the warning about “non-Synology Recommended memory module configuration” cause by the 3rd-party memory modules or because you are running 2x 32GB modules and exceeding the 32GB max of the Synology specs? Did it appear with the Crucial 2x16GB? I have an RS2423+ and both Synology and AMD spec for the V1780B max RAM is 32GB, so I don’t think I can even exceed that. But obviously, I will be going with 2x16GB 3rd party ECC DIMM, so I was wondering if I will see that warning too or not.
        REPLY ON YOUTUBE

      12. 20 years ago I sold 3rd party computer memory. We had the same issues with Apple, Cisco and many other brands. Never once did my customers ever have a problem. Memory modules are built to a standard, once met, it just works. :):)
        REPLY ON YOUTUBE

      13. If you’ve purchased Synology RAM, then I’ve got some great additional components for you… I sell small self-adhesive ECC enhancement Crystals, just apply it to the outside of the NAS. Each Crystal enhances the checksum and healing capabilities of your RAM by 16%.. Protect your data with this small investment.

        2 Crystals per-pack, the MSRP is $699, for today only they’re available for the low introductory price of just $299, and if you buy 2 packs, we’ll chuck in a 3rd pack for free…

        In seriousness though, Synology are smoking some strong shit at the moment, their 800GB NVMe is still listed at over £300, their 18TB HDDs going for £650… and given the fact they’re branded and marked up by 3-4x the market value, this is price gouging.
        REPLY ON YOUTUBE

      14. I do have question, and I’m confused on, why is your DSM 7 says “Not secure” and my has a paddle Lock. Please explain the concept? I’m confused?
        REPLY ON YOUTUBE

      15. I am planning to wait a few more months before upgrading my DS1522+. I currently have 16 GB of Synology memory. What are the benefits of greater memory?
        REPLY ON YOUTUBE

      16. I upgraded my DS2419+ to 7.2, and it’s upgraded unofficial 32gb is working just fine. Occasionally I get a notification if I reboot that it detected unofficial ram, but I ignore it ????
        REPLY ON YOUTUBE

      17. Just because they work now doesn’t mean they always will. Synology is the Apple of NAS vendors. They’re all about vendor lock-in.
        I say this as the owner of a DS918+. But I don’t think I’ll ever buy another Synology device. I’d like to get another NAS and move everything over to it, then reinitialize this one to use for backups, but we’ll see.
        REPLY ON YOUTUBE

      18. If Synology blocks using third party memory or discs, I will not buy a Synology NAS when it comes time to upgrade. I already stopped buying Samsung products because of their OLED screen policy.
        REPLY ON YOUTUBE

      19. 1821+ owner here, I also upgraded to DSM 7.2 while using 32GB Crucial DDR4 no issues to date. Many thanks for all your knowledge and continued testing Robbie appreciated 🙂
        REPLY ON YOUTUBE

      20. i did buy the crucial memory accordingly, but when i do install the modules , the nas don’t boot up, keep frozen, and don’t show the beep up sound. any suggestion?
        REPLY ON YOUTUBE

      21. My comment ended up flagged/deleted? Kinda sad considering I was saying thanks for making this video. I don’t really understand YouTube at all. Hopefully you can review my comment as it had helpful info for everyone. I’m going to purchase some ram from one of the Amazon links in the description so, hopefully that helps a little.
        REPLY ON YOUTUBE

      22. Thank you for such a detailed review for ram on this machine! I couldn’t believe how much Synology’s own ram cost on these. Just insane. I do plan to get the DS1522+, and 32GB ram for it.
        REPLY ON YOUTUBE

      23. The crucial ram linked is for CT16G4SFRA266 but the referenced one in the video is CT16G4SFD8266. I bought the former one and it didn’t work. I will give the one referenced in the video a try.
        REPLY ON YOUTUBE

      24. I know this video is a few years old, but the Timetec 8 GB (2nd link from the top of the list) is not the same physical size. Its a little bigger and the notch does not line up.
        REPLY ON YOUTUBE

      25. Hello, I put into my DS923+ 2x16Gb ECC Memory modules and works. The P/N of model is Kingston KSM26SED8/16HD. Now I’ve 32Gb!!. ????????
        REPLY ON YOUTUBE

      26. Comparing this NAS with a TS453E would be a good comparison. The 453E is smashingly good, after using it a while and QTS 5.1 BETA with multichannel and QTIER with the faster slots turns it into the perfect system, no need to do a thing with it. Plenty of speed and power at the pricepoint. If you want more I prefer the true intel stuff at that point.
        REPLY ON YOUTUBE

      27. Kindly forget other brands that are not CL 19 x 3, Crucial is ‘Crucial’ in this search…LOL 😉 2666mhz. 16Gb…why go for less or why go for more? Thanks.
        REPLY ON YOUTUBE

      28. Great video! I did a similar test trying to find the limit on my AS6604T which is also J4125 based but has two RAM slots. It’s funny because while the Intel Ark says this processor only supports 8GB max, I found someone on the Intel forums talking about how they were able to get 16Gb working so I figured I would try. I was able to install 2 Hynix 16gb DDR2400 sticks for a total of 32GB of usable memory but definitely failed when I tried to go higher. Either way super happy with having that much usable memory on this little server for some in memory databases even if the CPU is pretty weak.

      29. Many thanks Robbie and Andy for your multifarious inputs….they have guided me well along with Spacerex etc., Your presenting style does leave me needing somewhat of a ‘frontal lobotomy’ or is that a ‘bottle in front of me’? Kindly and warmly said….any chance you could slow down to the speed of ‘light’? ????????????
        REPLY ON YOUTUBE

      30. Anyone watching this if the specific ‘dual rank’ 16Gb Crucial works? i.e. most folks probably would only ask for 16Gb + 2Gb Max ram, especially as this is NON-ECC memory. Very ‘sketchy’ results online elsewhere what specific model works over time without major issues. Specifically for the ds420+ and Celeron 4125 ‘match’. I’m planning to buy shortly.
        REPLY ON YOUTUBE

      31. Thanks for your input guys. Points of note are that you are 1) showing unsafe times to remove drives. 2) Dual rank and CL=19 requirements. 3) Longevity statements from users and yourselves over time. Not much point to have a ‘cavalier’ approach to this test for most possible DS-423+ buyers. ‘We’ (many perhaps) just want to know that the Crucial 16Gb…aka 18Gb total works over time. Cheers!

      34. I upgraded my aging DS716+ quite a while ago from 2 to 8GB (the max officially supported by the N3150 inside) and even without any VM’s or Docker’s this makes a major difference. I really can’t get it that Synology does not ship it’s plus models with at least 8GB of memory (and a more modern processor). I would upgrade to a new plus model today if only they were shipping it with decent hardware… Now the difference is just too small.
        REPLY ON YOUTUBE

      35. Kingston do provide ECC memory – I have one stick of KSM26SED8/16MR in my 923+ and will hopefully have another one arrive tomorrow. How important are matched memory modules anyway – I know some models only have one accessible slot?
        REPLY ON YOUTUBE

      36. Just purchased a DS1821+ and so far, so good. However, the difference from a Drobo (Drobo FS, 5D, Pro or 5S) doing a name search on a Mac through finder for a file vs the Synology doing a search through finder is like night and day. The Drobo reacts much like a attached hard drive with results coming up quickly, where the Synology always takes 5 to 8 minutes before results start showing up and many times are incomplete. So, will RAM or M2 MVME help to speed this process up or is this just something I am going to have to live with.
        REPLY ON YOUTUBE

      37. Hi, great job.

        One question, because of the processor in the ds423+ the memory can only go to 16GB non ECC, or can we use 32Gb ECC?
        Have a nice day. Best regards.
        REPLY ON YOUTUBE

      38. Fix the description!!!!!!!!
        The “Crucial 16GB CT16G4SFD8266” link is leading to a “CT16G4SFRA266”, which doesn’t work!
        I bought this one and now I have to return it…
        REPLY ON YOUTUBE

      39. My understanding of RAM use, is that when you upgrade, it is advisable to use equal sized modules in each slot. It is also important, when adding a different sized RAM module, to ensure that it’s specification match those of the module already installed. Have I misunderstood this?
        REPLY ON YOUTUBE

      40. Great Investigative video. I’d like to share my system memory configuration with you.

        Synology DS918+ (came with a Single Synology 4GB SODIMM module), Intel Celeron J3455 CPU running at 1.5Ghz
        I am running DSM 7.1.1-42962 Update 3
        I removed the Synology 4GB module and installed a Crucial 16GB Kit of 2x8GB SODIMM Modules, of DDR3L-1600 CT2KIT102464BF160B
        I elected to use the Crucial memory modules as a great deal of research suggested that Crucial was a close a match to what Synology specification as I could get.

        I am running 4 HGST 4TB 7200RPPM NAS drives and the system has worked flawlessly.

        Is there a reason why a DS920+ should function any differently that mine.

        Always great and useful videos. Thank you. Cheers from Canada

      41. How come the sticks which worked in your DS3622xs appear to be non-ECC and some of those that failed appear to be ECC?

        I’m just looking at M471A2K43CB1 and M471A1K43CB1 in the table above and they are non-ECC sticks. You cannot typically mix ECC and non-ECC memory.
        TS256MSH64V4X, which failed, is ECC.

        Is it possible that Synology might have shipped non-ECC sticks in that NAS?
        Has anyone found non-Synology ECC 16G sticks which worked in the DS3622xs?
        Also, according to Intel, the Xeon D-1531 supports up to 128Gb RAM, has anyone tested 32Gb sticks in the DS3622xs?
        REPLY ON YOUTUBE

      42. If I bought the 923 and added a 16gb non ECC stick, would I likely have 20gb useable memory, albeit without any ECC functionality? Ultimately I’ll likely also replace the original 4gb with a second 16gb stick, but initially ideally I’d just like to throw in the single extra 16gb
        REPLY ON YOUTUBE

      43. One minor point is that they have said that they will support your warranty if it wasn’t that part (e,g. the RAM) that caused the fault. A specific example that they have stated is that if your PSU blew up (or something unrelated to the RAM went wrong), they would still assist. Their page also states, contrary to this video, that “Synology does not provide complete product warranty or technical support services if non-Synology memory modules are used for memory expansion”. It doesn’t say anywhere (at least at current) that they do not provide any warranty service (read: void warranty) if unofficial RAM Is used.

      45. By mistake I bought crucial CT8G4S266M instead of CT8G4SFS8266. I tried them instead of factory memory. They work without a problem, NAS had no problem running.

        I am running 2x 4GB of official Synology RAM. I am tempted to upgrade to 2x 16 GB of unofficial. I have two questions:
        1. Will my warranty be void when using unofficial RAM?
        2. Can anyone detail performance increase when going from 8 to 32 GB in my usage scenario?

      49. How important is the ECC memory? What would your suggestion be between (2) 16gb non-ecc modules from Kingston or Crucial (~$52 each) or (1) 16gb ecc module from Arch Memory ($155.00).
        REPLY ON YOUTUBE

      50. You mention the MB vs GB when you talk about how much memory is shown in the Ubuntu vs what you assigned in the Synology GUI.
        I think the more correct way of describing it is the binary vs decimal way of counting the bytes. Meaning 1024 vs 1000 .

      52. I had the Timetec 76TT26NUS2R8-16G dual rank 16GB stick installed in my DS920+ running DSM 7.1 for a week now without issue. Passed the ram check overnight also.

      53. I ordered the Timetec 4GB module and installed and when I checked the total it was saying 20GB! I checked the package the module it came in and it said 4GB. Then after further examination, it showed that the sticker that said 4GB was on top of another sticker. I peeled it off and looked at it……I was sent a 16GB, not 4GB! So that worked out in my favor. Somehow it got mislabeled. I only paid for the 4GB. BTW: it works fine, no issues.

      54. 920+ DSM 7.1.1-42962 upd2: Crucial CT16G43FRA266 (16Gb) didn’t work, NAS couldn’t start. I downgraded system to 7.0.1.-42218 upd5 – Crucial module still didn’t work. So I changed Crucial module to Kingston KCP426SD8/16 (16Gb). Boot process successfully finished after 2-3 min, Kingston module works fine. Upgrade to 7.1.1-42962 upd2 also finished well.

      58. Bought the crucial 16GB Module, and inserted it into my brand new 920+. I couldn’t get it to boot up, removed it and all was well…. but a it miffed I couldn’t get the ram to work. I saw this video and thought it I may be able to get it to work, but no such luck. I just keep getting the flashing blue light. In this state, how do you get the NAS to close down other than doing what you were doing…. ie holding down the power button until it switches off.

      61. Maybe it helps others, but the Timetec 8GB ECC 2600MHz memory on Amazon works in the DS1522 quite well and allows you to double your memory from 8GB to 16GB using the existing module installed and is under $35. Can’t seem to post a link to Amazon without it getting rejected…

      62. 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.

      63. 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.

        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.

      79. A couple of notes for anyone trying to do the memory test. Synology Assistant is a Desktop application (not a DSM app) – so you need to download it to your laptop. This app will show you the NASes on your network. Second, you need to change the settings for your NAS in Synology Assistant and check the “Memory Test” checkbox. This will give you a memory test button as shown in this video.

      81. 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

      82. 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.

        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.

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.

        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.

      107. 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.

      109. @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.

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.

      119. 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).

      120. 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.

      121. 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.

      122. 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.

      123. 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”… ????

      124. 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

      125. 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

      126. 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.

      127. 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’

      129. 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.

      130. 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
        REPLY ON YOUTUBE

      131. 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.
        REPLY ON YOUTUBE

      132. 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.
        REPLY ON YOUTUBE

      133. 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!
        REPLY ON YOUTUBE

      134. 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.
        REPLY ON YOUTUBE

      135. 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.

      136. 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

      137. 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?

      138. 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

      139. 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.
        REPLY ON YOUTUBE

      140. 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.

      141. I just got this as a upgrade tried going to custom route backplane was doa. I even converted a QNAP TS496 Pro to use Unraid and cool thing is it saw the full 4gb of ram I upgraded it to. The default is only saw 3GB.

        Is there a DOM built into this as well where the Synology os is installed incase we ever wanna try say freenas scale or unraid?
        REPLY ON YOUTUBE

      142. Interesting…. because I slapped a couple of cheap non-ECC 32’s (for a total of 64gb) into the DS1821+ and they work perfectly. That said, 64gb is major overkill as the system uses 90% of the memory for caching. Super annoying that the 3622xs+ limits the memory type

      144. Important Question: On the Amazon site, they have 8/16 versions of TIMETEC which are higher priced than the ones via the links on the NASCompares sites (for 220+). What is the diff between the ones linked and the more expensive ones that Amazon shows on the sale site for the official one. Speaking specifically about TIMETEC modules.

      146. It wasn’t clear from your video if you had removed the base 16GB that comes with the 3622xs. If not, these tests were guaranteed to fail. Unless Synology is using some sort of very exotic memory topology, you can’t mix ECC and non-ECC DIMMs on the same motherboard as far as I know (with the caveat that my knowledge is dated). This has nothing to do with Synology—this is a limitation of the CPU.
        REPLY ON YOUTUBE

      147. Great video Robbie. I installed Kingston 16G KSM26SED8/16HD ECC memory in my DS1821+ to give me 20G in total. Works perfectly. I had a complaint upon first boot-up that it was not official Synology memory but after that it was fine. I ran a full memory test and it passed perfectly. The 16G stick direct from Kingston’s website was £112. The same from Synology would have been about £380 and that is frankly preposterous. I have installed a Synology 10G card (£150) and paid £300 to Synology for 8 x Surveillance Station licenses. I would very much liked to have put in Synology memory and if it were even 2x the cost I would have done. But 3.5x is a complete rip-off.

        The big test will be if they decide in some future software release to stop supporting 3rd party memory, even in the prosumer series.

      148. I just don’t get why Synology’sown memory is so expensive. In the admittedly limited research I’ve one, I can find zero difference between their memory and Kingston for example. Works fine on my DS1621… if it just price gouging? I there a real reason?
        REPLY ON YOUTUBE

      149. Taboo? On Synology’s part maybe. For everyone else living in the real world this is a no-brainer. I also have a hard time believing that this (and also their HDD BS) would even remotely fly in the EU, if it weren’t for the fact that NAS’ are such a niche product.

      150. The Synology HDD is double the price to the same capacity WD HDD in my place. And even the price is so high, it is simply out of stock. So that I finally change to build a unraid server other then buy the new Synology NAS. Just because If HDD cannot be buy easily. It is risk to the data the if one HDD down, it will be so hard to replace a HDD.

      151. There is a program “Thaiphoon burner” that can modify/burn SPD info for memory.
        I wonder if Synology uses a simple “name tag” check for memory initialization, thus providing a way to use a modified stick

      152. I have DS322xs with 2 more official Synology memory (2 x 16G to a total of 48G) and the system still says that the memory is unofficial. I found out that the DSM 7 is still not so stable (I had a lot of problems with the system freezing, giving a lot of errors etc.). Let’s hope they will update the DSM in order to make it stable.

      153. Tried a Kingston 4gb ram module on a 720+. Tried to march specs to one pre-installed, 2666 MHz, cl19, non-ecc. No joy, system did not boot on DSM 7. Ended up using their original ram module. Expensive upgrade, but I guess it is the safer way. And given cost of nas and importance of data I think going for Synology ram kiiiiiiinda makes sense. Probably one of the reasons why Synology is not quite keen on dropping their prices.
        REPLY ON YOUTUBE

      154. In the UK, Synology would have to prove that the failure causing the warranty claim was due to the unofficial memory and nothing else in the device. Only they could they get away with not fixing it under warranty. Good luck proving that Synology. Just return your device with the default memory in place should you need a warranty replacement.
        REPLY ON YOUTUBE

      155. This is pretty much a reason to boycott Synology. They’re rebranding and locking down the system for no reason but to make their own customers’ usage harder (difficult to source upgrades) and more expensive (+400%).

      156. Your timing is amazing. Just did this on my 920+. Given that Synology memory is 115$ and Timetec memory is 27$, I opted to risk it. It works perfectly. Even did the memory check right after. Glad they’re less restrictive on the prosumer models. If Synology had been more reasonable on the pricing, I definitely would have paid a little extra for some peace of mind. Hell, if it had been JUST double the price, I would have paid it.

      157. My Synology ds1621xs crushed and can’t boot up after I upgraded 2X16 timetec ram into the two slots. Blue lights flashing continually on the first power up. When I swap it back to the original 8G Synology ram, it is still not booting and flashing blue light. Now can’t go into DSM to setup. Pulled all attached devices , HDD and cable line, it is still a brick. The timetec ram is compatible for this model and checked before on the seller website in amazon us. Is there anyway to boot NAS up before send it back for RAM? Anyone had same experience?

      158. I was tempted to buy the 1621+ but decided for the TS-653D from Qnap after I found out that the Synology doestn support Plex HW transcoding. But I wish I could use the 64GB on the Qnap to be honest.

      160. I spent a fortune on the official Synology RAM for this device and it STILL didn’t boot – thankfully Amazon being Amazon are sending a brand new unit less than 24 hours after contact (have to send the other one back) – although I’m tempted not to bother upgrading again, seems far too much hassle and VERY expensive.
