Synology DS218+ Unboxing and 8GB RAM upgrade

Synology finally released a new CPU refresh for their Intel CPU line, previously they have used the Intel Atom C2538 which has the dreaded Intel C2000 design fault unless you got the C0 stepping (Not available with Synology yet.). All B0 stepping CPU are effected but any DiskStation manufacture beyond February 2017 has the resistor fix. Here comes the Synology DS218+ recently released with the new Intel Celeron J3355, this CPU has only 2 cores compared to the higher tier Intel Celeron J3455 that has 4 cores but it is used in the DS718+ and the DS918+.

Just going to run through unboxing pictures for anyone that is keen on seeing what you get. Going to bundle this with Western Digital Blue 500GB and 640GB that I have available right now.





Contains

  • C2 Backup Free Trail
  • Quick instation Guide
  • Ethernet cable
  • 8 screws for 2.5″ HDD
  • PSU Adapter
  • Power Lead


  • Underneath has additional vents, there is also 6 pins that are accessible. Not sure what they are intended for….




    Quiet 12cm rear fan


    Screw-less HDD trays for Desktop 3.5″ HDD, there are four mounts point for Laptop 2.5″ HDD at the bottom.


    Easy accessible SO-DIMM slot to upgrade the RAM capacity of your DiskStation.


    Crucial CT102464BF160B 8GB DDR3L – 1600 SODIMM 1.35V CL11




    Insert the RAM at a angle then proceed in pushing it down to click into place. You may notice that the first SO-DIMM is blocked which has the default 2GB RAM configuration. I will add another post on how to remove/upgrade the first slot in the future.



    Slide the trays back into the slot, make sure you fully push the trays into the device.


    Then do a memory test using the Synology Assistant application, download from

    To enable memory test you must enable this through the settings (Cog icon), just tick Memory Test.


    Proceed in installing the DSM software onto your DiskStation, otherwise you can’t run the memory test.

    Once you are up and running, right click to do a memory test it will ask for your Admin password before you can proceed.


    There is no confirmation popup to tell you if it’s complete, if it’s beeps it has completed the test and reboot your system back online.

    Now to do a bench test………

      Hi,

      Do you think it’s possible to change the internal memory from 2 to 16Gb by adding tw 8Gb modules (Crucial CT102464BF160B 8GB DDR3L โ€“ 1600 SODIMM 1.35V CL11).
      I already know i have to disassemble the DS218+ to get this done.

      Regards,

      Marcel

      Hi, thank you for sharing your experience of a brand new NAS.
      Is DS218+ working normally on 2GB+8GB RAM?
      I am waiting for your further posting about upgrading RAM of this NAS.

      • poyu says:

        Works fine, you get better performance having matching memory modules. I’m in the progress in making a post to make it to 16GB

      Thanks very much for your blogs (this and replace 1st SO-DIMM).
      I’ve upgraded successfully my new DS218+ with 2x 8GB (Crucial CT102464BF160B 8GB DDR3L โ€“ 1600 SODIMM 1.35V CL11).
      Regarding to the post found in ‘https://forum.synology.com/enu/viewtopic.php?t=108102’ (by kipik ยป Thu Jan 07, 2016 10:36 pm) I’ve done the following things too:
      (1) disable the memory compression in Control Panel
      (2) connect to DS via SSH and change the line ‘ mem_default_mb=”2048″ ‘ in file ‘/etc.defaults/synoinfo.conf’ to ‘ mem_default_mb=”8192″ ‘
      All works fine.

      Hi!
      Thanks for sharing your experience!
      Do you get to use the 10gb?
      The official upgrade is 2+4gb and you are the only the only website who talk about using 8gb instead of 4gb in the extension bay without touching the main bay.

      Thanks!

      • poyu says:

        Hi, 2GB + 8GB worked fine, booted up fine and I did a full memory test. Ensure that you get the same model, you be fine.

        • sorcerer says:

          Poyu,
          Can you recall how long your memory test ran?
          My NAS works normal but recently starts to hang every time when it runs a backup to another Synology box. When it hung, the box has to manually power down and power up. Synology support is out of idea what is going on after submitting log files and suggested I run a memory test. But warned me the memory test will run hours. I need to find out how long the test will run before I can schedule this last ditch test.
          Thanks in advance.

          • poyu says:

            Hiya sorcerer, it’s hard to remember the duration I believe is up to 6 hours. I haven’t really timed it, I left it overnight and the machine booted as normal with no errors. Wish you luck, not sure how many TB you are backing up. The more TB you have the more memory usage you need, otherwise the RAM be full and you be waiting for the RAM to clear in this case it would be never cause it waits for compiling the whole thing in RAM

    8. Adam says:

      Thanks for the guide. I added Crucial CT8G3S186DM 8 GB (DDR3L, 1866 MT/s, PC3-14900, SODIMM, 204-Pin) memory to my DS218+ and did 4 memtests – all passed successfuly. With the 10 GB in total, everything runs smoothly.

    9. poyu says:

      That’s great, glad you found it helpful. Seems like the Synology do like Crucial for mix and match setup 8GB + 2GB, check out my other post to change the default 2GB RAM with another 8GB. Have fun

    10. Dary says:

      Hi, why are you mixing the 2 GB default memory with 1866 MHz with another DIMM which has only 1600 MHz?
      source: https://www.synology.com/en-us/products/DDR3

      • poyu says:

        Hi Dary, I’ve already have a pair of 1600MHz RAM that I’ve used from my RS815+ which at the time was compatible on Synology website. Every RAM got a timing table to enable mix and match RAM modules, this mix and match was a temporary solution. The default RAM can lower the timing to 1866MHz to 1600MHz anyway, was planning to changed the default 2GB to a matching pair at a later date.

        The price of buying PC3-14900 1866MHz to PC3-12800 1600MHz, is not worth the extra money for. Check out my post on replacing the default 2GB RAM there are some benchmark result.
        How to replace the default 2GB RAM

        Here is an why I believe it’s pointless aiming for 1866MHz, check out the GeekBench link there is hardly any big performance gains. Save your money and just buy which ever speed is cheaper between 1600MHz and 1866MHz
        DS218+ 16GB (1600MHz) vs DS918+ 16GB RAM (1866MHz)

      Hi, hoping you can help?

      I’ve just added the Crucial CT102464BF160B 8GB DDR3L โ€“ 1600 SODIMM 1.35V CL11 to the free slot on my DS218+ but the system is still only showing 2GB. All boots up and works fine just not seeing the memory. Did I miss a step?

      Btw I also ran a memory test via the Synology Assistant and everything passed.

      Cheers
      Marc

      • poyu says:

        Hello Marc,

        You would need to re-insert the RAM into the slot, ensure that the RAM connector is fully inserted at 45 degree while pushing it down. Motherboard don’t tend to ignore memory, they would either beep with error or boot up with the additional RAM. There is no extra steps

        • Marc says:

          Thanks, a 3rd reseat done the job. Not too sure why it wasn’t fitted correctly the first couple of times as it looked good. The system now sees the full 10GB.

          Thanks again,
          Marc

    12. John says:

      Hi! What would you recommend, one stick 8Gb or two sticks at 4gb of ram each?

      • poyu says:

        Hi John best to get one stick of 8GB, disassembling the whole unit for 4GB isn’t worth it. Mis-match RAMs like the 8GB + 2GB should work, dual channel would gives you a better performance but to day to day usage isn’t noticeable.

    13. FXsan says:

      Hi
      Thx for the sharing.
      as the cpu handles two ram channels, for me so the best is to put twice the same ram capacity to get the best performance (doubling ram BW).
      Also the datasheet https://ark.intel.com/products/95597/Intel-Celeron-Processor-J3355-2M-Cache-up-to-2-5-GHz- indicates that the cpu also supports LPDDR4 up to 2400MHz, which is much faster than 1600/1866 MHz…
      Did someone tried those ?

      • poyu says:

        Hello FXsan, the DS218+ has LDDR3/DDR3 RAM slots, you can’t interchange to DDR4 or LDDR4. The datasheet states that the CPU memory controller can handle LDDR4/DDR4 but it requires the correct RAM slot and motherboard chipset which this model does not, reason why they don’t choose the better generation? just cost issues. Hope this helps

        • FXsan says:

          Hi
          Sure if the cpu may support it, still the chipset and motherboard must do too, so onlyDDR3L in the DS218+.
          Finally I put 2x4GB 1866MHz CL13 in the NAS (from a Mac), with pairing the two cpu ram channels, but if the results are much better than with only one ram, like you well explain, I’m a bit surprised that results are not so good as yours (using same docker bhcopeland/docker-geekbench4) :
          https://browser.geekbench.com/v4/cpu/11611574
          strange that during tests cpu is only 15 to 35% (even in multi core)
          Anyway if latency difference self explains (your CL11 against my CL13), max bandwidth and mem copy are disapointing (-16%…?).
          So maybe there is something to configure better ram access, but is seems it confirms that the less expensive 1600MHz will be the best compromise for upgrade.
          For those like me who had a doubt ;- )
          Now there are 1866MHz CL11 also (like HX318LS11IB/4 ), but not in the budget I defined…

          • FXsan says:

            Hi
            after testing the 2x4GB 1866MHz MEMMWY0061, I was able to test the 2x4GB 1600MHz ref M471B5173QH0-YK0.
            Result on https://browser.geekbench.com/v4/cpu/11757839
            Conclusion, the 1866MHz is indeed slightly faster (but not in the frequency ratio, due to longer access time (135ns vs 130ns).
            But the 2x8GB you have is faster than my 2x4GB. I assume yours are dual bank while mine are single rank, hence the difference ? So in terms of perf I would rate
            -2x8GB 1866MHz
            -2x8GB 1600MHz (best compromise)
            -2x4GB 1866MHz (2911, 13.3 GB/sec)
            -2x4GB 1600MHz (2892, 13.1 GB/sec)
            -initial 2x1866MHz + any additional ram
            -initial 2x1866MHz
            BR
            FX

            • poyu says:

              Thank you FXsan for doing those benchmark, there isn’t much performance gain from this system once you get dual channel.

              Hence why for anyone reading this you should save your money, the 1%-2% performance boost between the 1600MHz CL11 and 1866MHz CL13 is not going to slow your system down. You should get higher rated RAM if they are the same price or cheaper, or you are planning to re-use the RAMs for another system that can utilise the extra speed.

              People shouldn’t stress out which speed to get either the 1600MHz and 1866MHz, while the default RAMs are rated 1866MHz CL13 they can reduce speed to 1600MHz when mixing two different RAM. Just make sure that you get matching RAM to get the most out of your Dual-Channel performance.

      As of Jan 2019, Amazon has the 1866 MHZ 8GB SODIMM for less than $3 more than the 1600 MHZ version so no need to downgrade the speed with this upgrade. This will probably also eliminate the need to disassemble to install and second 8GB module as I assume the performance improvement is minimal (but I would like to see the difference if anyone can benchmark).

      • poyu says:

        Hi Dan, if the pricing of the 1866MHz is just as cheap as the 1600MHz then you might as well get the fastest. But in benchmark it isn’t much of a performance upgrade check this comparison https://browser.geekbench.com/v4/cpu/compare/4725933?baseline=4787522

        DS218+ with 1600MHz vs DS918+ with 1866MHz look at Memory Copy, Memory Latency and Memory Bandwidth, not much speed gain. Hence why people shouldn’t really worry about faster RAMs only if the RAM is cheaper or you need every single drop of performance.
