Add a RAM Module on Synology NAS
The optional Synology DDR3 RAM module is designed for Synology NAS memory expansion. Follow the steps
below to install, check, or remove a RAM module on your Synology NAS.
To install a RAM module:
1 Shut down your Synology NAS. Disconnect all cables connected to your Synology NAS to prevent any possible
damages.
2 The RAM modules are located at the bottom of DS620slim.
3 Remove the 4 screws that secure the bottom panel. Lift up the panel and place it to the side. You will see a
pre-installed 2G RAM module.
Important: When you remove the panel, the sensitive internal components are exposed. Avoid touching anything
other than the memory assembly when you remove or add a memory module.
4 Insert the new memory module into the slot:
a Align the notch on the gold edge of the module with the notch in the slot.
b Tilt the card and insert the module into the slot. Make sure the module is properly inserted.
c Push down on the memory module with moderate pressure until you hear a click.
Note:
• Hold the memory module by its edges, and do not touch the gold connectors.
• Synology will not provide complete product warranty or technical support if non-Synology RAM modules are used
for memory upgrade.
