Just to add to some information for the following RAM:
Crucial 16GB (2 x 8GB) DDR3L 1866 (PC3L 14900) Unbuffered Memory for Mac Model CT2K8G3S186DM

System wouldn't boot on initial install with the RAM, re-installed original RAM back in (4GB), setup DSM - powered down installed new RAM (16GB) - System booted with no problems, and ran for 24 hours while transferring and loading files. Mysterious improper shut down in the middle of the night while idling. I removed one stick of RAM going back to single channel 8GB and the system has been stable for the last 40 hours, will post back if system crashes again on that particular RAM sku again.

DSM 6.1.5-15254 Update 1
Fully populated machine:
3 WD Reds -SHR
2 ADATA SX6000NP NVMe Cache Drives R/W
1 WD Purple - dedicated to Surveillance Station

**Edit: System is connected to a UPS

I have the same Crucial RAM on mine, no issues at all.

I just ordered my 918 +, in conjunction with it I ordered two CT8G3S186DM and two MZ-V6E250BW, as soon as everything will come I will tell you how it behaves

I'm interested in doing this too using the Crucial 2 x 8GB ones that folks have mentioned above - from this post and general Googling they seem to work perfectly.

The Synology website states: "Synology will not provide complete product warranty or technical support if non-Synology memory modules are used for memory expansion" (see https://www.synology.com/en-global/products/DDR3)

Does that worry anyone or am I being a scaredy cat?

I only just purchased my DS918+...in reality 16GB is probably overkill for me but an official 4GB extra one costs more than one of the 8GB Crucials so it just doesn't make a lot of sense to me to buy the Synology one!

Oh, and if anyone is interested, I found a neat little how to guide here (it's very basic...for those of us who are terrified of touching the inside of our machines!):

Nah, it's super simple to swap out memory sticks on these boxes. The older chassis (412+, 415+, 916+) was pain to get in there.

Adding one more data point:
[*] Corsair Vengeance 16GB Kit (2x8GB) DDR3L 1866MHz (CMSX16GX3M2C1866C11) does NOT work!

The DS918+ fails to boot with both, or just one stick inserted. I confirmed the sticks were OK in a laptop with memtest.

Failing to complete the installation of a new Windows 10 VM with only 4GB (in the end it was probably the USB3 driver rather than the lack of memory that kept crashing Win 10, and Ubuntu apparently), I thought it was time for a big upgrade, and given the limited availability of the the big Crucial chips in my part of Europe I ended up with V7, or VSeven, or whatever that is supposed to be pronounced.

16GB DDR3 1866MHZ CL13 16GB DDR3, PC3-14900, 1866 Mhz, CL9, 204PIN SO-DIMM
(V71490016GBS-LV)
Modelnr.: V71490016GBS-LV

I added it to the system 4GB, and my 20GB system seems to be running 2x8GB VMs wihout problems. There was some excitement immediately upon powering up the box, at first it declared the volume "migratable", claiming the disks came from another Synology, then promised me a reboot that ended up in failed power up, the power button would simply go blue for a few seconds and then off again, I removed cables, plugged in cables again and, voila, after a longish startup I am on!

May I know can it fully use the 32GB since after your insert of 2x 16GB crucial RAM (CT204864BF160B) the dmidecode result shows "Maximum Capacity: 16 GB".

Ended up getting 16GB working with no problems at all with this RAM:

Would you like to be more specific about "fails to boot"? My system has various behaviors like blue blinking for maybe 10 seconds and then off, or blue blinking for ever, or blue blinking for a minute perhaps and then powering up.

Oops, spoke too soon, my VSEVEN RAM worked OK for a few days but does not pass the RAM test. On the other hand, I found some older Kingston DDR3, in fact with bad benchmarks, that passes the test in 2x8GB https://www.memorybenchmark.net/ram.php ... .A00LF+8GB .

In fact I was curious if the DDR3 would slow down my VMs, so I Geekbench my Win 10, 2GB RAM, 2 core VM, and found that DDR3 scored around 2200 while DDR4 scored around 100 points lower. For what it's worth, running the same VM with 8GB RAM produced this https://browser.geekbench.com/v4/cpu/7761051

I concluded that when there is a RAM failure, like I said in my case a failure after days of operation, not a boot failure, the box will not boot again until there is a change in the RAM configuration. I was not getting past the blinking blue light until I removed a RAM chip, and actually I removed the working one from Synology, not the iffy VSEVEN that caused the crash. The system booted happily and was operation, but would not pass the memtest with VSEVEN installed.

I'm using Kingston HyperX Fury Black 16GB (2x 8GB) DDR3L 1866MHz Memory which works just fine and without any issues at all for my 918+

When purchasing the RAMs please note that 918+ needs DDR3L, those DDR3 RAM will not work properly due to the Voltage different.

For my DS918 + I bought one crucial CT102464BF186D.
After installation the DS shows weird errors. He closes himself and starts with flashing blue LEDs, but does not come online.
Quite the same errors as Tonycollinet. Does anyone have an solution?

As mRNACheng notes above, the DS918+ needs DDR3L rather than DDR3.

I understand the Crucial CT102464BF186D is DDR3...that is probably the issue. Also, are you mixing different sizes - like the stock one and your new Crucial? I read somewhere that you should have two the same...
