群晖1819+关于ecc内存检验的方法疑问
最近升级 了1819+的内存，原装内存是4G非ecc内存，在后台使用dmidecode -t memory命令查看显示的是root@oldtime:~# dmidecode -t memory
# dmidecode 3.2

不论我使用的是原装内存还是三星266616G的ecc内存检测结果都是这样的，所以问一下有没有大佬遇到同样的问题，我这个是否是ecc内存模式，按照B站上“”“科技宅小明”的验证方式是要显示mulit-bit ecc才算成功，所以我是不是买到了假的ecc内存，或者其他什么原因导致，希望各位高手帮忙解答一下，谢谢啦！

相同问题，原来的4G非ECC2400+4G非ECC2133原装条，显示的single，Total Width是64 bits；这次买了山寨三星ECC16G×2，还是显示single，换家店入了hynix ECC，继续显示single，但Total Width都变72 bits。
