I want to know what type of my memory channel in Linux, Single or Dual or etc..

  1. I try find it by check /proc filesystem, but didn't success. And then
  2. I use dmidecode to get system informations, and check, also didn't find.

How can I get it?

Search the dmidecode output for Interleaved Data Depth. Dual-channel memory has an interleaved depth of 2.

    What if I don't have the `Interleaved Data Depth" line at all there? – Dzmitry Lazerka Apr 19 '15 at 23:41

    And what if I have "Interleaved Data Depth: Unknown"? – Jay Jun 21 '16 at 23:58

    IDK whenever this is a reliable way to distinguish single vs. dual memory channel/support. Some systems will report Unknown while others might report 1 even though BIOS itself and other tools (i.e. CPU-Z) reports dual channel mode. – stamster Jan 22 '18 at 19:16
  • Hi, I'm using ASUS X99-E WS/USB 3.1 motherboard, but my dmidecode couldn't report any interleaved depth number. Does it mean my motherboard isn't using its quad-channel feature? – Clock ZHONG Jul 9 '18 at 15:30
