检测RAM通道数

20

我正在尝试确定（实际上无法访问计算机）它支持的RAM通道数（单，双等）-以及是否将其配置为使用该设置，例如具有四个插槽和双通道RAM，您如果将RAM插入正确的插槽，则只有双通道。

我知道如何确定插入了多少个RAM模块，我也不知道如何获取通道数。

ram

20

运行dmidecode。“交错数据深度”给出了通道数。

双通道内存的交错深度为2。

谢谢，如果“ Interleaved Data Depth” =“未知”怎么办？

错误的交错数据深度是“在一次交错传输中访问的来自参考存储设备的最大连续行数”。它与存储通道的数量无关。交错和通道是不同的事物，尽管使事情变得更复杂，但除了通常的库交错之外，通道也可以交错。DMI类型37提供了通道数量（但不提供通道安排）。有关更多信息，请参见SMBIOS规范。

执行dmidecode命令，但指定要使用的类型，如下所示：

$ sudo dmidecode -t memory | grep Size

这是我系统的输出，我总共有四个通道，而atm则使用两个。

这将显示DIMM插槽的数量，而不是通道的数量。

我尝试了dmidecode

dmidecode -t memory

幸运的是，该行Bank Locator: SOCKET 1 CHANNEL 7 DIMM 0告诉DIMM 170位于通道7中。该计算机支持32个DIMM，共有8个通道。下面列出了相应的频道：

您可能需要澄清您的答案，因为它目前似乎并未真正解决问题中的问题。

我成功使用了demidecode，发现我的机器有8个DDR通道
