Upgrading memory of a Synology DiskStation DS716+II

The Synology DiskStation DS716+II comes with 2gb as standard, but can be easily upgraded to 8gb. This helps with access times and allows the unit to keep more of your frequently opened documents in the fastest RAM rather than searching it on the HDD's

I currently use a DS716+II with 2 WD Red NAS Hard Dsics. It has ran flawlessly and 100% reliable since the day i purchase it.

Recommended RAM is Crucial CT102464BF160B 8 GB DDR3 PC3-12800

And can be purchased from Amazon for a reasonable price... see the link below...

How to Upgrade and Install new RAM to your DiskStation DS716+II

Start by shutting down your DiskStation through the web app interface, when it has fully powered down, remove the power and ethernet cables.

You are going to need the keys for opening the drive slots that would have come with your unit.
Unlock each bay to release the handle

Carefully remove each drive and store them safely! Ensure you make some kind of physical or mental note as to where each one goes back!

Locate the original memory module on the main board of the unit. Its a small green circuit board right at the front.
Next, remove the two screws in the base to remove the from facia, this gives a little more room to work with.
With the two screws remove the facia will start to pull away, be aware there are two clips at the top edge inside the case, you will likely need to gently push on them with (ideally) a plastic implement to help them release. Don’t force the facia or you may snap them.
Remove the facia, makes getting to the memory module clips a great deal easier...
FROM HERE ON! Follow static caution! Either use an earthing strap or remain near a radiator or other earth metallic item for the duration. Occasionally touch the item to discharge any static electricity from your person. Static can be a killer of electronic equipment!
Next, use something plastic… I’m using a screw driver here for pointing purposes only! Gently prise the white clips apart from the memory module...
Gently work each side of the clips and the module will eventually ‘pop’ out and spring up slightly...
Using your plastic tool, gently push the module ‘backwards’ out of the slot...
Eventually it will come free and you can slide it out...
Note the stern warning on the memory module that Warranty is Void if removed, therefore you carry out this change at your own risk and expense if anything goes wrong.
Next acquire your new memory module, and store the original one in the packaging and put somewhere for safe keeping.
Installing the new module is the reverse removing, very carefully line up the new module with the gold contacts pointing into the slot.
Take note of the notch on the contact strip, this ensures the memory will only go in one way.
As you manoeuvre the module into the slot you will need to give it a reasonable amount of force to engage it back into the clips, they are pretty strong and you will get a very defined ‘click’ when they engage. If you do not feel the module lock in properly the contacts will likely have a poor or non extant connection will will cause your unit to fail or become damage… again… only carry this out if you are confident!
Job done...
Replace the front facia of your unit - Reverse of removal
Replace your drives - In the same slots the came from!
Plug in your DiskStation and boot it up. Wait for it to fully initialise. The blue light will flash for a minute or so and you will hear the drives start up.
When the blue light goes solid, attempt to login to the unit.
Open the Resource Manager within DiskStation and you should now have 8GB registered at the bottom.
As you now have 4x as much memory than you started with, go to Control Panel > General and disable Memory Compression so your memory is running with optimum file size rather than using resources to compress files within the RAM. You don’t have to do this, but seeing as you have gone to the trouble of expanding the units memory you may as well exploit it as much as possible.
Your unit will require a reboot if you do disable Memory Compression.
And thats how to upgrade your Synology DiskStation 716+II memory module. Again…. only attempt this if you are competent with electronics and computers, and do be aware it will affect your products warranty.


  1. DSM 6.0.2-8451 Update 2 and a Synology DiskStation 716+II and the Crucial CT102464BF160B 8GB DIMM runs perfectly!

    1. No problem, also running DSM 6.0.2-8451 Update 2 here and been running flawless now for over 3 months.

  2. Hi !
    Today, 09/09/2017, I performed this operation without removing the facia, [but I have little fingers ;)], on my DS716+ii, DSM 6.1.3-15152 Update 4.

    No problem, even after disabling memory compression.

    Many thanks.

  3. Great post - but it's even easier if you unscrew the back over (two screws + one above rear usb ports - and simply slide off the main cover. Makes it a piece of cake. Rebooted with 8GB ram and feels much faster/responsive already.

  4. GREAT post - I did this last night following this and it worked beautifully! No need to remove the front cover, 5 min job to install the thing. Thx man!

  5. I just did this yesterday - I now have Virtual Machine Manager running with a Win 7 VM working perfectly! Thanks for the tip on which RAM to use.

  6. Thanks for the post! .. just bumped my DS716+II to 8GB.
    With DSM 6, the memory compression has moved to: Control Panel > Hardware & Power > Memory compression.

  7. How do I get to the two clips holding the front facia in? The one is exposed but the other is covered by the slots that are holding in the two hard drives.

  8. Thanks for an awesome walk-through! Especially appreciated the static caution, would have forgotten about it otherwise... :)

  9. Will Plex perform better after this mem upgrade?

  10. One year later...

    After my first comment (09/09/17), no problems, even after several updates of DSM.

    Again many thanks to Rob.

  11. Thanks for the guide! Just upgraded my device and working beautifully!
