Upgrade Synology DS1819+ RAM to 32GB

Recently got my hands on a Synology DS1819+ which offers a number of great features, one of which is the ability to support 32GB memory! Giving me more than plenty of resources for all kinds of Docker containers, virtual machines, and Synology applications.

In this quick guide I’ll detail how to upgrade your Synology DS1819+ to 32GB of RAM.

How to upgrade DS1819+ memory to 32GB

  1. Power down and unplug your Synology DS1819+
  2. Next turn the NAS unit over and remove the two screws

  3. Remove the factory installed 4GB memory module.

  4. Now install the Crucial 32GB kit memory cards into the DS1819+.

  5. Finally re-install the memory cover on the bottom of the NAS and power it back on. It may take the DS1819+ a few minutes to completely load while it does its memory check the first time.

It’s that simple. I certainly like how easy it is to access the memory slots compared to older Synology NAS models. A very welcomed improvement indeed.

  1. Simple compared to older Models.
    But I think the biggest news is that this is the first “budget” Synology NAS that can make use of ECC-Ram. No silent Data-corruption from Bit-Errors in Memory anymore.

  2. I was wondering if the DS1819+ will take 64GB of RAM – I have a DS1815+ that was suppose to max out at 6GB, but I saw someone had a link for Crucial memory to bump it to 16GB (2 x8GB). I have been running that configuration for a few years without incident. I’m looking to build a new DS1819+ setup with 8x8TB, 64GB and SSD caching (still working on some of the other details and I already have my 1815+ networked with LACP with all 4 ports – will continue that). Crucial has 32GB modules as does Samsung – I’ll let you know if I get to it.

    1. Peter,

      I believe the Synology DS1819+ only supports up to 32GB of RAM and that’s the highest I’ve tried. If you do get 64GB of RAM to work I’d love to hear about it!
