想請問下大家,加左條crucial DDR4 2666 16GB RAM 後有一直閃藍燈大約十分鐘都入唔到系統
升級RAM後係咪較長時間先入到系統? Thanks

有無試過淨係用條16G？

唔支援單條16GB

Bought one 16GB memory CT16G4SFD8266 but unfortunately did not work for the DS720+ (blue light is flushing and is not booting up).

睇咗幾個feedback /report , 就算係同一牌子, 同一容量, 都有機會用唔到.

Which RAM to Buy For DS720+ NAS
Answer: Samsung 8GB DDR4 CL19 2666MHz CL19, 1.2v Product Code: M471A1K43CB1-CTD
The author said:
"The original preinstalled RAM, which is the D4NESO-2666-2G, is bound to the motherboard in your DS720+ NAS (they're actually welded together) and is CL19 Samsung manufactured"
"Blogs and forums recommend the 16 GB or 8 GB RAM from Crucial. However, the Crucial CL19 RAM memory has some incompatibility issued with the original preinstalled memory on your DS720+ NAS in some cases the crucial memory will not be able to read SSD-NVMe M.2 cache also DSM will show a notification listing the Crucial or HyperX RAM as non official at every start up/reboot"
"You will not receive any messages in your DSM System event notifications if you install the Samsung 8GB DDR4 CL19 2666MHz Product Code: M471A1K43CB1-CTD because I've tested it myself on my DS720+ and I can say with certainty that it's 100% compatible and perfect work with different SSD-NVMe M.2 brands."
"There are people on YouTube and Forums who have unknowingly and naively installed 16 GB of RAM in their Synology DS720+ and DS220+ but they do not understand that the processor will never use the excess memory. Even if their system detects 16 GB of memory, it will never be used by their CPU."
Regarding 2+8GB ram ... "Out of a total of 10GB, you will be using only 8GB. The remaining 2 GB won't be used"

I think not only Samsung ram is compatible with 720+. However the more important part of the article is, " the processor will never use the excess memory". Really
... believe it or not 
Could anyone (using 2+8 or 2+16) show us the DS720+ memory utilisation screen capture, usage exceeding 8GB
ps. The article refers to DS720+ and DS220+ only. DS920+ might be in a different situation.

有人試過celeron j4125 maximum 可以用32GB ram, 遠多於官方網頁的8GB~
https://nascompares.com/2020/07/ ... installation-guide/
另外有人用ds220+測試（同ds720+硬件差唔多一樣）加16G 同32G....16+2正常亦可以用到，而32+2就已經入唔到DS

最近淘咗條三星16gb ram俾DS720+，少少波折但最後成功。賣家講咗個技巧，我分享俾大家參考：
“长按电源键关机，然后拆掉内存，用橡皮擦下内存金手指部分，重新安装内存，不要安装硬盘，注意是一块硬盘都不要安装的，然后开机，等待30分钟直至SATA灯变绿即可关机，装硬盘开机即可。”
一開始我同其他師兄一樣開唔到機一直閃藍燈，閃咗超過半個鐘都冇反應。跟住關機再用咗上面個方法，2分鐘唔使就聽到嗶一聲，再插返HDD再關機就得了。
