这里可查CPU、内存型号
https://kb.synology.com/en-us/DSM/tutorial/What_kind_of_CPU_does_my_NAS_have

  • 群晖型号：DS218+
  • CPU ：Intel Celeron J3355 Dual Core
  • 架构： Apollolake(x64)：
  • 内存：DDR3L SODIMM 2GB

群晖 DS218+ 原装内存只有 2GB，机器内预留了一个内存插槽，准备再加一个。

看了网上说群晖的机子认内存，而且最大识别到8G，也有说16G的，可以命令查询。

查看群晖内存 sudo dmidecode -t memory：

可以看到 Maximum Capacity: 16 GB

我这里只考虑加个 4G 的就行了，总共 6G，目前需求不大。。。

京东随便买了一个：

  • 协德 (xiede)1.35V低电压版DDR3L 1866 1867 4G笔记本内存条

我去，安上去直接翻车了。。。群晖不开机。

家里有个老的 Dell 笔记本是 8G 内存（2 x 4G），有个金士顿的

把金士顿的调换过来，群晖可以开机了，笔记本也没问题。
