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

  1. I can confirm that DS920+ with DSM 7.1-42661 Update 1 and 16GB Crucial CT16G4SFD824A.C16FJ works fine and without non-official memory message.

  2. user comment: I populated the DS920+ with four WD Red Plus 14TB drives, two Synology SNV 3400 and even tried a M471A1K43CB1-CTD Samsung memory module 8 GB DDR4 2666 MHz from my laptop which works.

  3. Riporto la mia esperienza:

    DS920+
    Crucial CT8G4SFRA266 8GB DDR4 2666 MHz CL19: funzionante
    Crucial CT16G4SFRA266 16GB DDR4 2666 MHz CL19: luce blu lampeggiante, no boot

  4. Does it have to be 2666 mhz to work with the 920+?
    I bought a 16gb 3200 mhz Crucial CT16G4SFRA32A and it doesn’t boot with it installed but just keeps flashing blue.
