群晖第三方内存兼容列表收录贴
一般不建议加内存，家用的话2g内存绰绰有余了，加多了没什么性能提升，机器的稳定性是否影响不好说。因为兼容性问题，群晖对内存的要求越来越苛刻，老机型系列的内存，市面大部分第三方内存都可以兼容，到20系列后，很多第三方内存都会翻车，遇到很多型号这台机器可以兼容，换到另外台机器又无法兼容，原厂内存又太贵，这里做个收藏贴，如果白群晖的同学，可以把自己加的内存发上来，到时候统计哪些品牌型号兼容性好，也算给后面同学指条路。
这是官方的内存参数，可以看出主流的型号DS920+、DS420+、DS720+、DS220+用的内存是一样的。
D4NESO-2666-4G4GB
DDR4 non-ECC Unbuffered SODIMM
EAN: 4711174723669
适用机种:
20 系列：RS820RP+, RS820+, DS920+, DS720+, DS420+, DS220+
19 系列：DS2419+, DS1819+
18 系列：DS1618+
内存不兼容几种情况：
1、加内存后无法开机。
2、加内存后可以正常开机，但是控制面板系统信息 无法显示增加的容量。
3、可以正常开机，也可以显示内存容量，但是系统事件会提示：检测到非Synology内存模块。
4、群晖助手DSAssistant检测内存无法通过。
可以按照下面方式回答：
群晖机型：
内存品牌型号：
可以的话附上内存照片
也可以SSH登录，获取内存信息，然后截图
输入下面命令切换到root权限
sudo -i输入管理员密码
然后输入下面命令，就可以查看内存详细信息
dmidecode -t memory
其中Manufacturer是内存品牌信息

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！
