Best alternative RAM will be from Crucial.  It is important to not mix different frequency/ speed RAM modules. You need to replace both RAM sticks in some cases to match this.

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 Press and hold the power button until you hear a beep sound to shut down your DiskStation. Disconnect all
cables from your DiskStation to prevent any possible damage.
2 The RAM modules are located at the bottom of DS1618+.
3 Remove the 2 screws that secure the bottom lid. Lift off the lid and place it to the side. You will see one 4GB
module pre-installed.

4 Insert the new memory module in the slot:
a Align the notch on the gold edge of the module with the notch in the memory slot.
b Tilt the card and insert the module into the slot. Make sure the module is properly inserted.
c Push the memory module with moderate pressure into the memory slot until you hear a click.

5 Replace the bottom lid. Replace and tighten the 2 screws you removed in step 3.
6 Reconnect the cables you removed in step 1, and then press and hold the power button to turn on your
DiskStation.

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.

To remove the RAM Module:

1 Follow step 1 to 3 of the “To install the RAM module” section to shut down your DiskStation, disconnect the
cables, and then remove the bottom lid.
2 Push the levers on both sides of the memory module outwards. The module will be released from the slot.
3 Hold the memory module by its notches and remove it from the slot.

4 Replace the bottom lid. Replace and tighten the screws removed in step 1.
5 Reconnect the cables removed in step 1. Now, you may turn on your DiskStation.

  1. Ah x2, according to this page the Crucial ct8g4sfs8266 should work with a DS1819+ but I still get memory warnings….. Sigh.
    IT seems as if these recommendations cannot be trusted anymore which is really sad.

  2. Ah, I just realized I experienced a copy-n-paste fault when ordering this mem. I managed to order the same mem model as for my DS1621+….
    Well, nice to know it works even in DS1819+ even though mem waring shows.
    So, back to the drawing-board and do it right this time.

  3. Are any/all of the above mentioned memory types CONFIRMED working, without the memory warning, in DSM 7.x and in the mentioned models?
    I ask since I got a Crucial CT16G4SFD8266 16Gb (mentioned in another page in here) to my DS1819+, running on DSM 7.0.1, but it pop-ups the memory warning….
    AND, it doesn’t seem to show directly, it took a while before it popped up.
    Seem to be working but not ideal to have the warning everytime it boots.
    None of the other upgrades I have done have any warnings/pop-ups (yet) and I’ve done my fair share of them. DS216+, DS216+II, DS218+, DS718+, DS1515+, DS1815+, DS1621+, no warnings. So, when this started…
