Check the amount of RAM on the server

rated 0 times [ 12] [ 0] / answers: 1 / hits: 21733 / 1 Year ago, mon, may 1, 2023, 10:28:31

Is there a way to check a server (without opening it up and physically looking) at the amount of ram that is in the box in terms of how many slots are free. Also I need to know how much ram it could possibly take?

I know I can check /proc/meminfo for the RAM but I'm really more concerned with the type of ram how many slots are free/taken. i.e. I need to know how much ram I can add and what type to add to a particular but have no idea how to go about doing so.

One nice tool (in addition to dmidecode) is lshw.

E.g.,

$ sudo lshw -short -C memory

H/W path               Device       Class      Description

==========================================================

/0/0                                memory     64KiB BIOS

/0/400/700                          memory     16KiB L1 cache

/0/400/701                          memory     1MiB L2 cache

/0/1000                             memory     2GiB System Memory

/0/1000/0                           memory     512MiB DIMM SDRAM Synchronous 400 MHz (2.5 

/0/1000/1                           memory     512MiB DIMM SDRAM Synchronous 400 MHz (2.5 

/0/1000/2                           memory     512MiB DIMM SDRAM Synchronous 400 MHz (2.5 

/0/1000/3                           memory     512MiB DIMM SDRAM Synchronous 400 MHz (2.5

Or

$ sudo lshw -C memory
