The performance tab of task manager shows a majority of memory details including the total amount of RAM, how much is in use, committed/cached and paged/non-paged amount of RAM, RAM speed and frequency, form factor, hardware reserved and even how many slots are being used in the system. The number of memory devices in the results of sudo dmidecode -type 17 is equal to the number of memory slots, so the command to print the number of RAM slots is: sudo dmidecode -type 17 grep 'Memory Device' -count The results of this command will be one integer number equal to the number of RAM slots.
