How to identify the installed Memory / RAM. Many people simply use free, which is available on every Debian system, to list the quantity of RAM installed (detected). Gnome users can install and use the hardinfo. KDE user can use kinfocenter. Check Available Memory Slots Linux impersonation of any person or entity, misrepresentation regarding any affiliation with another person, entity or association, use of false headers or other acts or omissions to conceal one’s identity from LV BET Check Available Memory Slots Linux. Later, I moved my role from supporting Solaris systems to Linux systems and I was struggling to get the same piece of info in Linux about the memory bank/slot and how memory is present in each memory bank. Today I got an audit work to validate the system data that someone has filled about Linux servers.

This is our sixth post on getting hardware information. In this post we will see how to get RAM details such as size, speed, make, maximum capacity allowed RAM etc. We already covered some hardware related stuff in this series so far as given below.
Get BIOS, Firmware, Hardware And Drivers Details in Linux/Unix

Example1: Find RAM size(Total, available, used) in Linux. We can use below five methods to get details.

Hi all,
I'm searching a PORTABLE way to get the available and total physical memory.
Something like 'getTotalMemory' and it returns the memory installed on my PC
in bytes, and
'getAvailableMemory' and it returns the available memory in bytes.
Do you know is there's a C function, a c++ Object or anything else that
compiles in Linux and Windows to get these data?

The POSIX symbols _SC_PHYS_PAGES and _SC_PAGE_SIZE could be what you are
looking for, at least for UNIX-like operating systems:
long phypz = sysconf(_SC_PHYS_PAGES);
long psize = sysconf(_SC_PAGE_SIZE);
Of course, you need to calculate _total_ physical memory by hand then.
Unfortunately I don't know a portable solution to obtain the _available_
physical memory the same easy way.
Windows does not support all of these symbols, so you will need to call
something like GlobalMemoryStatus() which fills a MEMORYSTATUS
structure, that itself contains a member dwTotalPhys containing the
_total_ physical memory for this system and dwAvailPhys indicating the
_available_ physical memory.
Suggestions and better solutions are welcome. Please let us know what
others would recommend.
