Is it possible to get information in the terminal in which mode the memory works. When you enter the command "sudo lshw -C memory" produces:

Where is the information about single or dual channel mode? If it's not there, how do you get it?

Look at the value of the "slot" parameter. You have A0 and A1 there, which means that the mode is two-channel, pusho the first letters (channel) are the same. It would be A0 and B1, then there would be a single-channel mode.

You can definitely find this out only in the BIOS, since the physical location of the bars does not guarantee the mode of operation - it can be locked manually.
