Thanks for helping me. Although, many parts were identified, but not the memory. |

Why not just open up the case and look at the RAM chips? Even laptops can be opened.
Alternatively, you should be able to download the manual for the motherboard from its manufacturer's website. That may not give you who manufactured the RAM chips, but it should include the specifications for them.

See if the lshw program is installed, it should give you what you need or does on my machine.

^ This (but I'd rather sudo lshw -C memory), or sudo inxi -am.

yes, it works witht that lshw command. I was using the first one you gave me lspci -vvvk. Thanks for your help. Do you know of a cheat sheet with all the commands like those?

I know you're asking for a command, but I honestly do trust real physical things.

The important bit is this - DIMM DDR3 Synchronous 1333 MHz - any manufacturer, as long as it this type.  |

Reviewing the man page for any command is always a good idea.
When I did that for dmidecode, I found:
Code:
dmidecode -t memory
However, the man dimdecode BUGS section says:
