Using Synology NAS, DSM 7.1 and Unofficial Memory Modules for DSx20+ series

NAS systems are not cheap and nor are the accessories! However, one area that many new/existing NAS buyers take issue with more than most is the cost of official NAS memory. It’s an unfortunate fact that any computer system that has been built/tailored towards a specific purpose, is going to end up costing more. This usually comes down to much more specific design requirements and NAS drives are no different. But when it comes to Memory modules, people are slightly less forgiving. When a NAS brand sells it’s branded memory, many are quick to raise that the brand rarely makes the memory itself and instead they are putting their branded labels on memory from the likes of Kingston, Samsung, ADATA or Crucial. Now, this is only partially true, as brands tend to test a wide range of memory in the development phase of their products and then settle on the best choice based on that system architecture (no doubt factoring cost of course too) and then THAT memory is made the brand’s recommended choice, labelling it brand-approved. Where things get murky is when brands start to become rigid on their system’s use of other memory and how that impacts brand support and how the system treats ‘other’ or ‘unofficial’ memory.

In the case of Synology, this can lead 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. Nevertheless, many users who look at Synology’s pricing for their official memory modules might be thinking “HOW MUCH???”:

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:

We conducted a wide range of tests of memory from Crucial, Transcend, ADATA, Kingston, Sabrent and ADATA DDR4 SODIMM memory. These tests were conducted with a Synology DS220+ and DS920+, each running DSM 7.1. Here are the results from a video over on NASCompares:

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.

Synology DS920+, DS220+, DS720+, DS420+ and DS1520+ NAS Memory Tested

Now, before getting to the confirmed working memory that works in DSM 7.1 on the popular Synology Plus Series NAS right now, it is worth remembering that official Synology memory is always going to be the ‘ideal’ choice for the NAS. Despite reservations of price and (in some places) availability, this is still the memory that is going to present you with the least hurdles in the event of ALL support claims with Synology. Additionally, official memory will ensure no ‘warning – incompatible/unsupported memory installed’ message being displayed in DSM 7.1. Most home users will be able to ignore this warning no doubt, but if you are installing a Synology NAS for a 3rd party (friends, family or professional installation), it might un-nerve the receiver. It is for reasons like these that you might still want to opt for the official Synology memory. In that case, you can find the official memory modules available from Synology here:

D4NESO-2666-4G

D4ES01-4G (ECC)

D4ES01-8G (ECC)

D4ECSO-2666-16G (ECC)

However, we have been testing ALOT of memory with the Synology Diskstation Intel J4125 and Intel J4025 series of NAS devices since DSM 7.1 was released (DS920+, DS220+, DS720+, DS420+, DS1520+) and the following 3rd party memory modules are all confirmed to work in those systems.

IMPORTANT

  1.  The Synology DSx20+ series of NAS devices all arrive with default 2GB or 4GB of memory internally that is attached to the controller board/PCB which CANNOT be removed. Therefore you will ONLY be able to install a single memory module to upgrade these systems.
  2. When installing a new memory module, the Synology NAS system may take longer than usual to boot that first time (as I found out to my somewhat embarrassing error!), so give the system upto 20mins to boot the first time you install a new memory module.
  3.  The Intel CPU inside these systems has a maximum memory support of 8GB and they recommend that all memory matches the frequency/speed (Synology provide 2666Mhz DDR4 on these systems). So, try to err towards 2666Mhz (though we have successfully tested both 2400Mhz and 3200Mhz). Additionally, having in excess of 8GB is not guaranteed to mean the CPU can actually use more than 8GB in its architecture internally.

4GB Confirmed to work on DS920+/DS220+/DS720+/DS420+/DS1520+

The following 4GB Modules of DDR4 SODIMM memory have been tested in the DS920+, DS220+, DS720+, DS420+ and DS1520+ NAS running DSM 7.1. The Links used below will take you to amazon (it SHOULD re-direct to your own country/storefront automatically) where this memory is available. HOWEVER, thanks to their site having a policy of substituting product links to something else in the event the original product is out of stock, MAKE SURE to check that the memory modules for 16GB and 32GB SODIMM modules are DUAL RANK or ‘DR‘, as Synology NAS typically have trouble with SR/SINGLE RANK modules above 8GB. When in doubt, use the model ID.

8GB Confirmed to work on DS920+/DS220+/DS720+/DS420+/DS1520+

Now, when it comes to 8GB Memory modules on the DS920+, DS220+, DS720+, DS420+ and DS1520+ NAS running DSM 7.1, it is once again worth remembering that the CPU has that 8GB recommended maximum memory in place from both Intel and Synology. So, although all six of the tested modules below WORK, the jury is still out on whether you will be able to use them to their fullest extent. Additionally, remember that this will be paired with the 2/4GB of memory that the NAS has soldered to the controller board internally, so you will end up with either 10GB or 12GB of visible memory inside your NAS.

16GB Confirmed to work on DS920+/DS220+/DS720+/DS420+/DS1520+

Finally, we have the largest current memory that works in the DS920+, DS220+, DS720+, DS420+ and DS1520+ NAS running DSM 7.1 – 16GB in a single DDR4 SODIMM non-ECC module. For many users, the idea that a 16GB RAM stick for their NAS from Kingston, Crucial or Samsung will cost less than a 4GB official module is just too damned tempting! Much like the 8GB modules, it is really important to remember that these are substantially higher than the recommended maximum of the CPU by Synology and Intel, so although these have been tested and confirmed to work by both me (Robbie @ NAScompares) and many online sources, I would still ensure you have at least 2 backups in place of your data at all times regardless.

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 DS120j, DS220j and DS420j (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 18TB Seagate and 20TB WD Red 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 7.1 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.

      1. previously I upgraded to Kingston 8 gb KVR26S19S8/8 for 3 yrs and it’s working fine. now I decided to upgrade SK Hynix HMA82GS6AFR8N-UH 16gb 2Rx8 PC4 2400mhz. I bought it as used item. the seller agreed to my request, Test first before payment. so I brought my DS920+ to her store and it’s working fine for version DSM 7.2.1-69057. now I had 20 gb of RAM.????????????????????????????????
        REPLY ON YOUTUBE

      6. 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?

      8. I was able to upgrade my DS923+ (DSM 7.1.1-42962 Update 4) with 32gb for $150 using A-Tech 32GB (2x16GB) RAM Replacement for Synology D4ECSO-2666-16G, D4ES01-16G | DDR4 2666MHz PC4-21300 ECC SODIMM

        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…

      10. 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

      11. 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

      12. I have DS1821+ with 10Gbs network card. Running 6x 12TB discs in RAID6. I edit videos and pictures on the NAS.
        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?
        REPLY ON YOUTUBE

      13. Please make a video regarding the long-term effects! Of course I would be very happy to see only a short video as I hope there are no failures despite long-term usage.

      15. 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.
        REPLY ON YOUTUBE

      16. 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.

      17. 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.

      18. I installed the Timetec 16GB DDR4 2666MHz PC4-21300 Non-ECC Unbuffered 1.2V CL19 2Rx8 Dual Rank 260 Pin SODIMM memory in my DS220+ and it recognized it without any problem, the memory review took just over 7 hours and had no problems, my DSM version: 7.1-42661.
        Thank you very much @NASCompares for this analysis. Greetings from Mexico

      19. 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.
        REPLY ON YOUTUBE

      20. I have bought Crucial CT8G4SFRA266 8gb ram. (Single rank) It seems to not work on DS420+ with version: 7.1-42661 update 4 Or have I bought the wrong memory? i have this ram running around 1 hour nothing happens.
        REPLY ON YOUTUBE

      21. 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.
        REPLY ON YOUTUBE

      22. 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.
        REPLY ON YOUTUBE

      23. 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.

      24. 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).

      25. 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!

      33. 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?

      34. 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.

      45. 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!

      46. 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!

      47. 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

      48. 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.

      63. 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+.

      75. 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?

      76. 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.

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?

      82. 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).

      84. 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.

      87. 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.

      88. 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.

      89. 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)

      91. @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?

        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.

      95. 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.

      96. 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.

      98. 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.

        REPLY ON YOUTUBE

      102. 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).

      103. 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.

      109. 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.

      110. 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

      134. 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.
