    • Locate those 2 tabs on the left side inside the device.

    • Lift them up off the metal brace

    • You may have to bend the metal support bar to remove the case. Bend it back if you do.

    This step could really use a better illustration of the removal technique. The plastic here is extremely stiff and it can be hard to bend it enough to move the tabs.

    This is the best technique I found, that will avoid damaging the plastic facing of the case. I am using the iFixit photo as a guide. Take a flathead screwdriver and place it down within the DS412, head facing up. Stick the head in between the metal bar and the plastic casing, and at the midpoint between the two tabs. Apply gentle pressure.

Hi is it also possible with a Synology ds216play? Or is the RAM not modular in this Drives?

Very nice guide. Thank you!

Thank you for the guide, just to ease it up a bit for everybody following, the best way to pull the two tabs from step 4 was to use small spoon (or anything metal) and use it as a crowbar from the inside (do not try to put force from the outer rim, but really from inside of the Synology itself (against the metal beam the tabs are holding to).

did these steps and now my DS412+ won't boot anymore. just the blue power light for a few seconds, no hard drive or fan will turn on.

after putting the old RAM in the slot nothing changed. cannot find any error, how do I find out what's wrong here???

This guide was great. Thanks for posting it!

I upgrade to 2gb RAM last night with no problems. I used "Kingston Technology ValueRAM 2GB 1333MHz DDR3 Non-ECC CL9 SODIMM SR X16 Notebook and Portable Memory KVR13S9S6/2" from Amazon.

System is humming along nicely now.

Thank you for this guide.

I upgrade my RAM without any trouble.

The use of two tea spoon to lift the tab in step 4 is very useful.
