How to upgrade memory in Synology DS216+ and DS216+II

UPDATE: This upgrade method applies to DS216+ and DS216+II models


 
Synology recently intoduced new, reasonably priced, 64-bit Intel processor based NAS model: DS216+. What makes it interesting to me is that this model support BRTFS filesystem and it also allow you to run Docker containers (among many other things) however memory is limited by 1 GB.

Synology also offers similar model with double number of CPU cores and double amount of memory (2 GB) for ~50% premium in price: ~$450 for DS716+ vs ~$300 for DS216+.

However, it is possible to upgrade memory in both models for up to 8 GB. Procedure for DS716+ is much simpler but cost of that unit is significantly higher.

Possibility to upgrade memory in DS216+ makes it a very good value for money: ~$335 for DS216+ with 8 GB RAM vs ~$485 for DS716+ with 8 GB of RAM.

Please note that some memory modules may not work with this unit. I strongly suggest to buy following module as it has been tested with DS216+ and DS716+:

Crucial 8GB Single DDR3 1600 MT/s (PC3-12800) CL11 SODIMM 204-Pin 1.35V Notebook Memory CT102464BF160B

Disclaimer: Memory upgrade most likely will void warranty. DS216+ unit disassembly is not as easy as in other models and you may potentially cause damage to it if you will attempt to follow guide below. Don't blame me if you'll break it.

But you will be fine. Just take your time and be gentle. It is not that hard to pull unit apart and then put it back together. It took me about 20 minutes but I spent most time figuring out how to remove various components and taking photos along the way. Again, don't rush. Take your time, be gentle and use common sense (don't apply too much force, etc).

What you need to do first is: power off unit, unplug it, remove plastic cover near hard drives and remove hard drives.

At the back of the unit unscrew 4 screws around fan and an extra screw in lower right corner.


Lay down unit on its side and take a look inside from side where hard drive were installed. See metal bar on top secured by 2 plastic clips? You will need to pull this bar slightly to "unlock it" and then push plastic cover slightly back. You should be able to pull it with just using your fingers. This is the only part in this guide where you need to apply little force but please be gentle. Take your time and be careful.


Red arrows pointing UP but you actually need to pull metal bar DOWN.

Then you should be able to remove that part of plastic cover completely. Just slide it out.

On a side of a chassis you will need to remove metal bracket secured by a single screw.


This is how it looks when removed



Just put it away for now. On other side on the unit you will need to remove plastic bracket which is "attached" to a fan. Again, you will need to unscrew just one screw.


Then you will need to remove fan which is connected to motherboard. Remove (pull) plastic connector from PCB and carefuly remove silver coloured tape attached to a cable. This tape is kind of "fragile" so be careful but its only function is to keep cable secure.


Then you need to remove 4 screw that hold chassis and plastic cover together.



Now is most delicate part. You will need to pull out chassis along with attached motherboard from plastic enclosure. Be careful, take your time and be gentle. Take a look from both sides and see how it is attached to enclosure.


On the back you will find 3 components that "stick out" from enclosure: 1) Ethernet and USB ports 2) eSATA port 3) Power connector. In order to remove motherboard you will need to gently push out all 3 of these components to "release" them from enclosure. Again, be gentle, take your time and be careful.


Pull out chassis along with motherboard. This is how it should all looks like when done

Motherboard still attached to a chassis but that is fine. Take a look at motherboard


Now you can remove Synology 1GB module


and install new Crucial 8GB module


Well done! Now you need to put everything back together in reverse order




Install your hard drives of choice.
 

I've used pair of SanDisk Ultra II 960GB drives. Something that you may also consider as reasonably priced alternative to mechanical hard drives



Power on unit and you should be able to see additional memory available


You may also want to disable memory compression in DSM as it probably no longer required.

Enjoy your new improved DS216+!

  3. Hi Andriy, great tutorial. I am thinking of upgrading my DS216+ also. Did you see any seal so that it will be visible that the NAS is opened?
    Not all photos on your blog are shown, but I think I will manage with the ones that are shown and the text you wrote with them.
    Is your system still stable?
    Many thanks!

    1. Hi greyhead2! I didn't find any "warranty" seals apart from a sticker attached to original Synology memory module which you don't need to remove anyway. However, silver coloured tape which is designed to secure fan cable is very fragile and once removed it will change its "appearance". It won't look "new" anymore and I think that just by looking at it Synology warranty technician will be able to tell if unit was disassembled.

      I am refering to these photos:
      https://3.bp.blogspot.com/-S0C26YE6ou4/Vs7Ytg4ys1I/AAAAAAAAUe4/lJjm6Jd5now/s320/2016-02-22%2B20.23.36.jpg

      By the way, I am not sure why you can't see all photos. They all hosted on Google's Blogger. I can send them all to you if you like, just let me know.

      System is very stable, I didn't have any issues so far and I've built bunch of docker containers by now. Everything works as expected. Docker engine is a little outdated but it works fine.

      Good luck with upgrade! :)

  6. Thank you for the guide. I opened my brand new DS216+ successfully with these instructions and installed same Crucial RAM module. After that ran Synologys installation wizard and it installed DSM 6.0, no issues or error messages so far.

    In my unit that black plastic bracket had crack when I opened it.

    Amazon.de suggested me that very same Crucial CT102464BF160B memory after I put DS216+ into basket. I suppose some else also bought this combo.

  7. Hi,

    Just curious as why you went with the SSD? Is there a significant performance increase with a NAS? I just purchased a DS216+ and still trying to decide on which disks to go with.

    Thanks.

    1. Hi! I just didn't want to buy mechanical drives anymore. I've had 3 drives failed on me over last year and I no longer need very large capacity NAS. Instead I would prefer better I/O performance and better reliability. Low noise is also important factor for me. I hope that SSD drives will last longer. They definitely faster and they silent. I also use Docker engine within DS216+ itself so I/O performance is important, especially during docker build process.

      Delete
  8. Works well, thanks!

    WARNING: One thing to be very careful about whe reassembling the NAS is how much to tighten the four screws holding the motherboard in place. If the screws are tightended too much or little, the power button won't "click" any more and will be continually pushing. For me, this caused the NAS to randomly shutdown every 1-2 days.

  9. Hi Andriy, thanks for the write up.

    Could you give us some real-world examples of performance boosts from the memory upgrade?

    ReplyDelete
    Replies
    1. Hi Jay,

      For me this is more about possibility to run memory intensive application(s) rather than performance boost.

      Here's my example:
      I run 3-node cluster of Apache Cassandra database (via docker). Memory utilizaton is at around ~90%. Each cluster node requires ~2 GB of RAM. Without memory upgrade it would not be possible to run cluster.

      Of course not everyone need this and in real world it is not practical to run Cassandra cluster on Synology NAS but it is inexpensive and effective way for me to learn how distributed databases work.

      This is just one example and there are many other use cases with what you can do on DS216+ with 8 GB of RAM.

      If you need SAN to just serve files over CIFS/NFS, don't bother with memory upgrade. But if you also want to run various applications, memory upgrade is highly recommended.

  11. I've got some issues when I put the auto-off and auto-on enabled due to the fact that sometimes the Nas doesn't boot-up. I set the auto-off at 01.30 and the auto-on at 07.00.
    I only have this problem. Everything else is running well.

      I could not unscrew the two screws black color without damaging the screw slots: "extra screw in lower right corner" + screw related to "plastic bracket Which is" attached "to a fan". Well, I added a micro-drop of penetrating oil (WD-40, Valvoline, etc.) and screw out almost alone. Sometimes we get using our head what we fail with our hands.

    1. So after 2 weeks here's the update:

      DS216+II with latest DSM 6.0.1-7393 Update 2. Memory compression disabled.

      Running 7 docker containers, gitlab + mariadb + rabbitmq + 3 debian.
      Mem usage 19% xD

      3TB of transfers later and i found no issue whatsoever. 100% uptime. The speed feels the same. I don't thing it's "faster".

      This is perfect for those, like me, run a lot of docker images and other memory consuming applications. But don't expect a big increase in performance if don't use this kind of stuff.

      PS:
      I think we can mark kingston KVR16LS11/8 as a "certified" memory hehe :)

    1. I feel like it would be best to power the unit on once to ensure it is not a lemon, then to do the upgrade. I've ordered this unit, and am contemplating doing this upgrade to it off the bat. Once I've made sure it works :)

    2. Hi there! I agree with you, it make sense to power on unit first to ensure it is working properly and then upgrade memory. When I did uprade on my unit I did it straight away because I've got both unit and new memory module on the same day.

  26. Hi Andriy,

    Thanks a lot for the tutorial! I have DS216+II and consider to perform the memory upgrade.

    You suggest to use following memory:
    - Crucial 8GB Single DDR3 1600 MT/s (PC3-12800) CL11 SODIMM 204-Pin 1.35V Notebook Memory CT102464BF160B

    However, when I click on it - it takes me to amazon with following memory:
    - Crucial 8GB Single DDR3L 1600 MT/s (PC3L-12800) SODIMM 204-Pin Memory - CT102464BF160B

    Please note the difference in DDR3 vs DDR3L & PC3-12800 vs PC3L-12800.

    I found out that the difference between these two RAMs is nothing but the voltage consumption. The DDR3L RAM consumes lesser voltage compared to the DDR3. Also the lower the operating voltage, the faster the memory can theoretically operate.

    My question: Can both of these memory types be used for upgrade? Very likely yes, but what do you think?

    Thanks again.
    Cheers, David

  32. Hi Andriy,

    I did this upgrade some months ago (even made a comment on here earlier), but have run into some issues over the past couple months. Whenever there are any DSM updates or I simply restart the NAS, the unit hangs and fails to respond. I will then need to physically remove the power from the unit, then manually power back up.

    I reached out to their "support" and this is the first thing they pointed out to me...the additional RAM. They told me to remove the 8GB stick, replace with the original 1GB and monitor. They claim that the additional RAM can damage the hardware, which I think is crap, but it's an easy out for them.

    Have you, or anyone you know, experienced instability issues of this nature after upgrading?

    Thanks!

    1. Hi Justin,

      I had issues with DMS upgrade few times as well when system didn't reboot and I had to power cycle it. I was not sure it was related to memory upgrade but after your post I think it might be.

      It may sound strange it is technically possible for vendor to introduce artificial 'issues' on software level for systems with non-standard memory configuration. I don't think Synology will ever do this on purpose ...

      Last DMS upgrade (DSM 6.0.2-8451 Update 1) went well for me and system rebooted automatically as part of upgrade process without any issues.

      Delete
    2. I have had issues on rebooting too even without the ram upgrade, that the 216+ would fail to reboot automatically without physical reset. I got in touch with Synology's support and it seems to be a problem with the BIOS. You can try upgrading it to the latest BIOS from Synology.

      Delete
    3. Thanks, man! I've raised service call with Synology to get latest BIOS version.

    4. Thank you very much for this info! I've raise a call with Synology, they sent me 2 files to perform BIOS update. After update my NAS can reboot properly (don't need to powercycle anymore). By the way, I didn't have any issues submitting service call for my upgraded Synology unit.

      Makes no sense to use CPU in compression, when you have 8GB of RAM. The NAS barely uses the whole memory.

    Replies
    1. Hi Sausmaster,
      Hardware (CPU) appears to be the same, most likely memory is upgradable. However, keep in mind that procedure described above won't apply for DS416Play. It may be easier or potentially more complicated to disassemble DS416Play comparing to DS216+.

    1. No, I don't think SSD will provide any performance benefits for NAS throughput. However, SSD will definitely outperform mechanical drives for I/O intensive tasks running within NAS unit itself (docker containers, databases, etc).

  47. Perfect instructions. Took about 10 minutes. The "most delicate part" is the only place I was stuck a bit. And putting the cover back on. Need to align the groove. Thank you very much for the detailed instructions!

  49. Great tutorial!

    I'm currently owning a DS216SE and was interested in upgrading to DS216+ II but this tutorial made me wonder if the DS216SE memory is also upgradeable. Synology lists all three models (DS216SE, DS216+ and DS216II) as non memory upgradeable.
    I wanted to ask if you know anything about my unit and its memory.

    Thank you

    1. Those models don't have memory slots, the chips are soldered to the logic board. In general, only the + models have the slots.

  50. Thanks for this quide. Went great. I added the following - Kingston HyperX Impact Black 4GB 1600MHz DDR3L CL9 SODIMM 1.35V Laptop Memory (HX316LS9IB/4)

    No issues. Well overkill for my uses, but it allowed me to turn off memory compression and it's super responsive. Big step up from my 213j!

  53. Thankyou for the info
    Just up'd ram on my MacBook Pro mid 2012 to 16G as it happens the ram is the same as that on DS216+II so i repurposed 1 -4g module to DS216+II seems to be working properly. I am brand new to the NAS world your instructions were easy to follow and all seems to work good. Ram is hynix 4GB 2Rx8 PC3-12800S-11-12-F3.

  57. Hi Andriy, thanks for great tutorial...
    I wonder how it works after upgrade to DSM 6.x and all this time in use... Would you do anything different? One more question: where you see benefit of SSD mostly (which use cases), cause buying ˜ 1TB SSD vs 6TB HDD is big difference in capacity, so I wonder if speed difference is really so important here... Thanks

    1. Hi Ewoks,
      It's been more than a year since I've upgraded memory in my Synology unit. No regrets so far, system is super stable and reasonably fast. For me main benefits of SSD is reliability and I/O performance when I am running services within NAS unit itself (docker, databases). SSDs are silent, very light and they don't generate much heat. 6 TB HDD could be a good choice if you really need that much storage.

  61. Thank you Andriy for this guide.
    I upgraded memory module in DS216+II with Crucial DDR3 4GB 1600MHz (CT51264BF160BJ). It works great and first thing I noticed is that NAS is more responsive now.
