There are probably multiple ways to get it, but the first one that comes to my mind involves the 'hwinfo' command, from the package of the same name. I don't remember exactly how I invoked it, but I have a historical trail of files listing the hardware specifications of my last few machines as they've changed over time, each generated from the output of that command. If I search the latest such file for "DIMM", I see two entries, each for a different DIMM (i.e., "RAM stick"), each with multiple data items. The fact that there are two of them gives you the "number of sticks used" you asked for. Those entries are sub-entries of a larger entry called "memory", which has a data item called "size", which is the "total RAM" you asked for. One of the data items in each sub-entry is "product", which appears as if it might be the "model number" you asked for. (It certainly looks like a model number, anyway.) Another is "vendor", which appears to be the "manufacturer" you asked for. Another is "size", which gives you the "amount of RAM on each stick" you asked for. Another is "clock", which is the "speed of RAM" you asked for. Another is "description", which at least in my case specifies (as part of what appears to be a freeform string) that the DIMMs I'm looking at are DDR4. I don't see that information specified anywhere else in the listing. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
