How to do it:

Add a RAM Module on DiskStation
The optional Synology DDR4 RAM module is designed for DiskStation memory expansion. Follow the steps
below to install, check, or remove a RAM module on your DiskStation.
To install the RAM module:

1 Shut down your Synology NAS. Disconnect all cables from your Synology NAS to prevent possible damage.
2 Remove the hard drive trays from the drive bays. An empty memory slot is located on the inner right side of
your Synology NAS.

3 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.

4 Insert the drive trays back into the drive bays.
5 Reconnect the cables removed in step 1, then press the power button to turn on your Synology NAS

To make sure DiskStation recognizes the new memory capacity:
1 Install DiskStation Manager (DSM). (See the next chapter for more information.)
2 Log in to DSM as admin or a user belonging to the administrators group.
3 Check Total Physical Memory in Control Panel > Info Center.
If your DiskStation does not recognize the memory or does not start up successfully, confirm that the memory is
installed correctly
