Let’s use two useful parameters that can be added to the free command: free -ht The last line belongs to the swap memory, which is reporting around 1GB of usage.īut this byte based numbers are not easy to read. It is normal to see lot of cached memory in the buff/cache on Linux operating systems, this memory can later be freed and used if really needed. Then you have the Free colum that is showing around 1GB, and the others called ‘shared’, ‘buffer/cache’ and ‘available’. The second colum called ‘used’ shows the the RAM used by the operating system, in this case around 9GB. The total OS RAM in bytes is 32753636, which can be translated to 32 GB of RAM installed on the system. Total used free shared buff/cache available The free command is the most classic terminal based tool to check memory usage on Linux / Unix operating systems. Here is the list of the top 5 commands that can be used to find LInux RAM size in Linux. How can I Find RAM size in Linux operating systems?

Lot of times, because of order mistakes, dedicated servers providers will give you less hardware resources than the ones you purchased. On this post, we will find out how to find RAM size in Linux / Unix operating systems with 5 useful commands. See man proc for more detailed information on the meminfo file.When you order a dedicated server or cloud server with your web hosting provider, there is one thing you must check always when you first login into your system: your hardware must be exactly the same as ordered. Therefore, MemAvailable is the total memory minus the memory used by currently running programs. The kernel won't reallocate the memory used for currently running programs, but it will reallocate memory used for caching to programs that need it, because it can just read that data back from the hard disk if it's needed again. MemAvailable is the amount of memory that can be given to programs to use. MemFree is the total memory that's not being used for any of those things. The Linux kernel allows memory to be used for caching frequently-used files so that you can access their data faster in addition to currently running programs. MemFree is the amount of memory not being used by your system at all. It's not unusual for digital storage to have less actual capacity than advertised capacity, so this is most likely in line with what dmidecode reported - that is, the advertised capacity of your RAM. In your case, it says that you have 3467664 kB total RAM. MemTotal is the total usable memory in your system. proc/meminfo reports current memory usage on your system, along with some other information about your memory. Thanks to this table, you can retrieve this information without having to probe for the actual hardware.

This table contains a description of the system's hardware components, as well as other useful pieces of information such as serial numbers and BIOS revision. Most likely, your motherboard came with support for more RAM than was originally installed.ĭmidecode is a tool for dumping a computer's DMI (some say SMBIOS) table contents in a human-readable format. The official specifications for your laptop don't list a maximum RAM capacity, just that it came with 4 GB of RAM. I would guess that this is most likely correct. In this case, it is reporting a maximum 8 GB of RAM. Your BIOS should correctly report the maximum supported RAM on your computer.
This program attempts to gather information about your hardware from your BIOS. Where are they? And what do MemTotal, MemFree and MemAvailable precisely represent?

I think the pc has a 4GB memory card mounted, but neither with Gibibyte or Gigabyte unit system I'm able to sum up and find those 4GB here. Then again, the file /proc/meminfo tells me this: MemTotal: 3467664 kB I was thinking my HP 15g-207nl supported at max 4GB of memory, but there I see an 8GB as for the maximum capacity. Memory Array Mapped Address Handle: 0x0016 Type Detail: Synchronous Unbuffered (Unregistered) Looking for information about total memory on my laptop, I've found the following but I have some doubt about the meaning.įrom the dmidecode command I obtain: Handle 0x0010, DMI type 16, 23 bytes
