Upgrade RAM on a Dell Inspiron 5580 laptop

The easiest way to do this is to visit the Crucial site, and scan the computer if you use Windows. However, on Linux, find out details about the RAM installed open a terminal window and enter :
$ sudo dmidecode | more <enter>

And scroll through the list till you get to the DIMM block. Here the details of the RAM are mentioned as shown in sample below.

The RAM manufacturer serial number is also there with the model of the RAM. Both can be searched on the internet to find out more details.

I upgraded the Dell Inspiron 5580 RAM to the Crucial CT16G4SFRA266 and it works fine so far. Note that this model of RAM is dual rank, so it could be a tad slow, but unnoticeable. If the laptop has a SSD and also 16 gb of RAM, it won’t be discernible.
