How to Get Size of Memory DIMMs on AIX / Solaris / HP-UX / Linux ?

Solaris :

memconf – memconf reports the size of each SIMM/DIMM memory module installed in a system. It also reports the system type and any empty memory sockets. In verbose mode, it also reports information of banner name, model, CPU/system frequencies, address range and bank numbers for each module.

Usage:

memconf [ -v | -D | -h ] [ explorer_dir ]
v – verbose mode.
D – send results to memconf maintainer.
h – print help.
explorer_dir – Sun Explorer output directory.

Requirements:

One of the following Hardware and Operating Systems:
• Sun SPARC workstation or server running SunOS 4.1.X, Solaris 2.X or later.
• Sun SPARC workstation or server running Linux with sparc-utils and /dev/openprom.
• x86 system running Solaris 10 6/06 or later with /usr/platform/i86pc/sbin/prtdiag.
• perl installed in your path. Perl V5.X is recommended, but perl V4.X will work. You can download the Perl package for Solaris from Sunfreeware.com if you don’t already have it installed.

Installation:

# chmod 755 memconf.gz
# mv memconf.gz memconf

Sample output:

• On a Solaris Sun Fire V240  system:

# ./memconf
memconf:  V2.22 30-Jan-2012 http://www.4schmidts.com/unix.html

DMIDECODE COMMAND

Run the DMIDECODE command and look for the data where the word “Physical Memory Array” starts and go through each line to get detailed information. In some new systems you can also use the command dmidecode –s  memory and dmidecode –t 17 , where “s” means string and “t” means type. Let’s just use dmidecode here for now.

[root@nucnoovs50 ~]#  dmidecode -t 17
