Optional Synology memory modules are designed to expand the memory of your Synology NAS. Follow the steps below to install, check, or remove a memory module on your Synology NAS. The following table shows the memory configuration for best practice:
To remove the memory module
1. Shut down your Synology NAS. Disconnect all cables from your Synology NAS to prevent possible damage.
2. Remove the drive trays from the drive bays. The memory slots are located on the inner-right side of your Synology NAS. You will find a memory module that is pre-installed.
3. The memory slots are numbered as shown below.
4. Push the levers on both sides of the memory module outward. The memory module will be released from its slot.
5. Hold the memory module by its edges and remove it from the slot.
6. Insert the drive trays back into the drive bays.
7. Reconnect the cables removed in step 1, then press the power button to turn on your Synology NAS.
To install the memory module
1. Follow step 1 to 2 of the “To remove the memory module” section to shut down your Synology NAS, disconnect the cables and remove the drive trays.
2. Insert the new memory module into the empty slot:
a. Align the small gap between the gold connectors of the memory module with the notch on the empty slot. Insert the memory module into the slot. Make sure that the module is properly inserted.
b. Gently push down the memory module until you hear a click.
3. Insert the drive trays back into the drive bays.
4. Reconnect the cables removed in step 1, then press the power button to turn on your Synology NAS.
To make sure your Synology NAS recognizes the new memory capacity
1. Install DiskStation Manager (DSM). Please see “Install DSM on Synology NAS” for more information.
2. Sign in to DSM as admin or a user belonging to the administrators group.
3. Go to Control Panel > Info Center and check Total Physical Memory.
If your Synology NAS does not recognize the memory or does not start up successfully, please make sure that the memory module is installed correctly.
Hi,
Have you run into any problems running Kingston KSM26SED8/16HD sticks listed in the article? Do they work in ECC mode properly?
I am considering an upgrade for my DS923+ and the utopian vision of spending merely 125 eur for two Kingston 16GB ECC sticks rather than 170 eur for single Synology 8GB ECC stick looks very tempting.
Also huge thanks for running this site and the YouTube channel. Great work! 🙂
