[心得] DS218+ 升級 8G RAM

晚上收到了 DSL DDR3L 1866 4G, 趕緊裝上去測試
DS218+ 分解前建議先看過前人的 YouTube
免得拆了沒必要的螺絲

安裝後實測結果如下: (使用 dmidecode 指令查詢)

從 type 20 的數據看來, 這兩條 RAM 並沒有跑雙通道
(Interleaved Data Depth: 1)
需要再研究一下有沒有辦法解除封印
不過目前暫時不怕 docker 把 RAM 榨乾了

$ sudo dmidecode --type 17,19,20
# dmidecode 3.2
Getting SMBIOS data from sysfs.
SMBIOS 3.0.0 present.
