I've seen a video clip suggesting that upgrading the RAM over the officially supported threshold confuses the way DSM manages caching. Would be beneficial to try an unofficial upgrade with the NVMe caching.
Did some testing with 32GB modules before I found this video. I ended up using a 16GB 3200MHz module instead of 2666MHz because there isn't much of a cost difference. The NAS works well with a bit of speed up using the 3200MHZ module as its more to do with the increase in RAM. The 16GB DDR4 module I used is a Samsung M471A2K43DB1-CWE with a memory arrangement 2RX8 (dual rank). Be sure to buy dual rank for your Synology memory upgrades, supposedly they work better.
Thank you! But there’s question - can all available memory be fully utilized? Can you please run multiple virtual machines for full memory utilize and run stable check for about day?
Very interesting with the success of the 16GB module. Curious why you never test a 8GB module since there maybe a greater success rate 🤔 The 220 and the 420 have the same processor and base ram. Perhaps just a matter of time before the graphical distortion begins to appear 🤷🏼♂️
By looking at the screen shot of memory utility, it looks like the 16 GB RAM doesn't get utilized by Synology, all 16 GB RAM free, not even cached works. Only the 2GB RAM came with the device works. I installed the Kingston 4GB RAM non ECC CL19 and all 6GB RAM got utilized. Synology only supports up to 6GB RAM so extra RAM might just be a waste. Intel Celeron J4025 CPU only supports 8GB RAM on this NAS.
@@darkftforce I don't know... in the video shown the value of memory composition in resource monitor with Used 772 MB, Buffer 187.5 MB, Cached 619 MB and Free the whole 16 GB. This is a similar value that I used to have when I had 2 GB RAM that came with the box. Then I installed 4 GB RAM for the total of 6GB which is the max DSM can support, I saw all values increased Used 1.3 GB, Cached 4.1 GB Free 326 MB on the idle system. It means the additional 4GB RAM got utilized by DSM. I suspect the whole 16 GB RAM here does not get utilized at all because it's way over the max supported of 6GB RAM so I think the 16 GB RAM could be a waste and useless. Better to install the 4GB RAM to be safe and match the spec.
@@thachvu6665 He has another video from several months ago with this exact unit The OS has no reason in this case to be using that much - in that video you can see the full allocation of RAM is usable as he boots up VMs with 8gb and 14gb The 6GB max spec is only as they have not validated the stability any modules higher than that, Just as a Desktop system has a Qualified Vendor list There is no issue with detection or utilization by the OS that I've seen
Few commenters stated that the CPU for this DS420+ Intel Celeron J4025 which actually supports only 8GB according to Intel datasheet. There is no point of upgrade more than a single 4GB module. Yes you can add more and it may works as it boot up but the OS can't use more than what the CPU can't handle. To truly test usability, log in the shell/terminal and forks of threads and see if you can actually allocate more memory than 8GB. Highly doubt it.
It actually can use more than 8GB though. My QNAP with a J4125 says the same - 8GB but the 2x8GB modules I have work fine and the system can and does use more than 8GB at times. I have had many systems over the years where I have had more RAM than is officially supported by the CPU. I imagine that is just what is officially tested at the time of the CPU being released.
It followed your directions with the ddr4 16 gb, but it was not accepted.... I can not figure out why. You think they adapted the DSM to no longer accept foreign RAM?
Same here. Already had my DS420+ and DS220+ running fine with 8GB extra but neither boots up with the 16GB installed. Wasted some good money on memory that I can't use now.
It is very Appleish of Synology to only support their overpriced RAM modules. There are only three major memory manufacturers in the world. I'd be interested to know how Synology can justify the price and warranty stipulations.
Intel Celeron J4025 only supports max 8gb of RAM. I can not see it using more than 2gb with 16gb stick. This video smells fishy... Not sure why synology installs only 2gb and offer 4gb as upgrade.
@@martynaslukas4340 No. CPU will work ok with more memory, but Intel supports only 8GB. If you want support for more memory you have to buy the more expensive Xeon procesor.
Graphical inconsistencies almost certainly done on purpose so when a customer sees it they think its bust and contacts them with it they can id it even if the additional ram is removed. Shoddy anti consumer practice if you ask me. Glad to see maybe they learnt this time.
I can't think of a more stupid thing Synology can do than this (only its own branded RAM)!!! I have had 3 Synology NAS units at home and it's time for me to find an alternative brand!
If the pricing of their branded DIMM would be comparable, even twice as expensive, I would accept... but it is 10 times more expensive than compatible named brands. Ridiculous
that crucial 16 will be looking real nice in my 920+

answer is no

I get the blue flashing like you get with a 32gb with 8GB and 16GB sticks
Hwo is suppling ram to synology (oem) ?? 🤔
The cpu does not handle 34gb of ram? Unsolder the 2 gb and you may get luck with the 32gb 🤔🙄✋🔆🔆🔆
Do you have a link to the 16 gig module?

You can change the disks order no problem thats why the disks trays are not numbered. Qnap its different at least in ooder models 🤔🙄🔆🔆🔆

You should test if you can use all that memory. Just because it shows up that you have that much memory it doesn't mean you can use it all.
