Questions & Answers
What is Synology Memory & RAM?
Synology Memory & RAM are certified modules designed to enhance the performance and stability of your Synology NAS by increasing multitasking capabilities and reducing data processing latency.
Which Synology NAS models support memory upgrades?
Most Synology Plus and XS series NAS devices support memory upgrades; refer to your model’s specifications page on Synology’s official website to confirm maximum capacity and compatible module types.
How do I check the current RAM installed in my Synology NAS?
Log into DiskStation Manager, navigate to Control Panel > Info Center > General, and review the System Memory section to see installed and available RAM.
What are the benefits of upgrading RAM in my Synology NAS?
Upgrading RAM improves file transfer speeds, enhances virtual machine performance, accelerates database queries, and boosts caching efficiency for smoother multitasking.
Can I mix Synology RAM modules with third-party memory?
For optimal stability and full warranty coverage, Synology recommends using only Synology-certified memory modules; mixing third-party modules may cause compatibility issues.
What is ECC RAM, and does my Synology NAS require it?
ECC (Error-Correcting Code) RAM automatically detects and corrects memory errors. Synology RackStation and FlashStation models often require ECC modules for enterprise-grade data integrity.
How many memory slots does my Synology NAS have?
The number of memory slots varies by model. Check your NAS’s hardware installation guide or Synology’s specifications page to identify how many DIMM slots are available.
What is the maximum memory capacity for my Synology NAS?
Maximum RAM capacity depends on the model; typical Plus series NAS support up to 32 GB, while XS and RackStation models can handle up to 128 GB or more—verify on Synology’s website.
How do I install new RAM modules in my Synology NAS?
Power off and unplug the NAS, open the chassis, align the module notch with the slot key, press firmly until it clicks, then close the chassis and reboot your device.
Will upgrading RAM void my Synology warranty?
Upgrading with Synology-certified memory modules does not void your warranty. Using non-certified modules may void warranty coverage, so always choose official Synology RAM.
How can I verify that newly installed RAM is recognized?
After rebooting, open DiskStation Manager and go to Control Panel > Info Center > General to confirm that the total memory reflects the newly installed capacity.
Does Synology offer a warranty on memory modules?
Yes, Synology provides a limited lifetime warranty on its certified memory modules. Refer to your region’s warranty policy for specific terms and coverage details.
Will additional RAM improve my Plex or Docker performance?
Yes, increasing RAM allocates more resources to applications like Plex and Docker, resulting in faster media transcoding and smoother container operations.
How do I troubleshoot memory-related errors on my Synology NAS?
Check the Resource Monitor for unusual RAM spikes, reseat modules, update DSM firmware, and run memory diagnostics in Package Center to identify faulty modules.
Are memory speed and latency important for Synology NAS?
Yes, faster memory speeds and lower latency improve data access times; always choose modules that match or exceed your NAS’s specified frequency for peak performance.
Where can I purchase Synology-certified memory modules?
You can buy Synology-certified RAM directly from Synology’s online store, authorized resellers, or certified e-commerce partners listed on Synology’s official website.
