linux系統如何查看內存型號

在Linux系統中，您可以使用以下命令來查看內存型號：

```

sudo dmidecode -t 17

```

這個命令將會顯示您系統中安裝的所有內存模塊的詳細信息，包括制造商、型號、序列號、容量、速度等。請注意，您需要具有sudo權限才能運行這個命令。

如果您只需要查看內存的總容量，可以使用以下命令：

```

free -h

```

這個命令將會顯示您系統中所有內存的總容量、已使用的容量、可用的容量等信息，但不包括內存模塊的詳細信息。

$ sudo dmidecode -t memory

執行后顯示如下：

# dmidecode 3.0

Getting SMBIOS data from sysfs.

SMBIOS 3.0.0 present.
