linux系统如何查看内存型号

在Linux系统中，您可以使用以下命令来查看内存型号：

```

sudo dmidecode -t 17

```

这个命令将会显示您系统中安装的所有内存模块的详细信息，包括制造商、型号、序列号、容量、速度等。请注意，您需要具有sudo权限才能运行这个命令。

如果您只需要查看内存的总容量，可以使用以下命令：

```

free -h

```

这个命令将会显示您系统中所有内存的总容量、已使用的容量、可用的容量等信息，但不包括内存模块的详细信息。

$ sudo dmidecode -t memory

执行后显示如下：

# dmidecode 3.0

Getting SMBIOS data from sysfs.

SMBIOS 3.0.0 present.
