Lots of manuals on the Web (https://unix.stackexchange.com/questions/215206/detect-number-of-ram-channels, https://serverfault.com/questions/564268/how-do-i-get-my-memory-channelsingle-channel-dual-channel-etc-type-in-linux, https://superuser.com/questions/1092324/cant-get-dual-channel-memory-status-from-linux-why) suggest that one can get the information about the single/dual channel mode through dmidecode. Let's try what they suggest:

roo@host:~# dmidecode | egrep -i "(dual)|(single)|(channel)|(bank)"
Bank Locator: Not Specified
Bank Locator: Not Specified
Bank Locator: Not Specified
Bank Locator: Not Specified
root@host:~# dmidecode -t memory | egrep -i "(dual)|(single)|(channel)|(bank)"
Bank Locator: Not Specified
Bank Locator: Not Specified
Bank Locator: Not Specified
Bank Locator: Not Specified
root@host:~# dmidecode -t 17 | egrep -i "(dual)|(single)|(channel)|(bank)"
Bank Locator: Not Specified
Bank Locator: Not Specified
Bank Locator: Not Specified
Bank Locator: Not Specified
root@host:~# dmidecode -t 37 | egrep -i "(dual)|(single)|(channel)|(bank)"
root@host:~#

Am I doing anything wrong or am I out of luck?
