At the beginning of the output you’ll see the maximum memory size allowed by your PC, which is important—you can’t put two 4GB memory modules into a machine that only allows a total of 4GB of RAM. Once you’ve scrolled down a little further, you’ll see the rest of the memory details for each piece of RAM that’s installed.
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.

It is essential that your Linux system runs at an optimal level. A few simple terminal commands provide access to all relevant information and help you monitor memory statistics.
In this tutorial, learn five powerful commands to check memory usage in Linux.
We also provide detailed explanations of what they do and more importantly, how to interpret the results. The commands will work with nearly all Linux distributions. In this instance, the commands and the results are presented using Ubuntu 18.04
*Access to a command line / terminal
*User with sudo privileges
*The apt package manager
Entering cat /proc/meminfo in your terminal opens the /proc/meminfo file.
This is a virtual file that reports the amount of available and used memory. It contains real-time information about the system’s memory usage as well as the buffers and shared memory used by the kernel. The output might differ slightly based on the architecture and operating system in question.
This is an example of what the /proc/meminfo file looks like in Ubuntu 18.04:
Pick the Right Casino. Players often ignore this all-important step, so I decided to start precisely with. Any trusted online blackjack strategy guide will start with basic strategy. This approach informs players, based on their hand and the dealer’s upcard, which action is most likely to win. Using basic strategy reduces the house edge of the game as much as possible, and in games that use only a single deck, gives players a slight edge over the house. Basic blackjack strategy is simple to understand, with only minor. Use the best blackjack strategy for real and take all you have to the real money tables to see them work. Now you have mastered the blackjack strategy table you’ll discover from our site the best casinos online that tailor for blackjack. Another strategy is to use online casino bonuses to increase your bankroll. Online blackjack tips and strategies in marketing. If you are dealt a pair of 8s or Aces, split them. A pair of 8s totals 16; it is the worst blackjack hand and the Basic Strategy will have you stand in most cases. Vice versa, a pair of 10-value cards totals 20; it is a good hand to risk it. Never stick to the ‘dealer rules.’ Dealers must hit on 16 and stand on 17. Online Blackjack Strategies and Tips Using Blackjack Strategy Charts Online. The good news about online blackjack is that there is no shortage of available. Advanced Online Blackjack Strategies. What you’ll find when you’re trying to learn how to win at blackjack online is. Adjusting Your Online.
The terminal displays the information in kilobytes.free Command to Display the Amount of Physical and Swap MemoryLinux Memory Slot Information Guide
Typing freein your command terminal provides the following result:Linux Memory Slot Information Check
The data represents the used/available memory and the swap memory figures in kilobytes.totalTotal installed memoryusedMemory currently in use by running processes (used= total – free – buff/cache)freeUnused memory (free= total – used – buff/cache)sharedMemory shared by multiple processesbuffersMemory reserved by the OS to allocate as buffers when process need themcachedRecently used files stored in RAMbuff/cacheBuffers + CacheavailableEstimation of how much memory is available for starting new applications, without swapping.
Compared to the /proc/meminfo file, the free command provides less information. However, it is easier to understand. The key figure being the available value as it displays how much memory is still available for running new applications.
The free command has multiple options to format the output so that it better matches your requirements. The table below lists the most useful variations of the free command.OptionsResult-boutput in bytes– koutput in kilobytes– moutput in megabytes– goutput in gigabytes– ldetailed low and high memory statistics– oold format (no -/+buffers/cache line)– ttotal for RAM + swap– supdate every [delay] seconds– cupdate [count] times
Note: As with most commands, entering man free displays an overview of all variations and descriptions of the results.vmstat Command to Report Virtual Memory Statistics
The vmstatcommand is a useful tool that reports virtual memory statistics.
vmstat provides general information about processes, memory, paging, block IO, traps, and CPU activity.
The detailed description listed below provides an explanation for each value in case you need assistance in analyzing the results.
*Procs
*r: number of processes waiting for run time.
*b: number of processes in uninterruptible sleep.
*Memory
*swpd: amount of virtual memory used.
*free: amount of idle memory.
*buff: the amount of memory used as buffers.
*cache: amount of memory used as cache.
*Swap
*si: memory swapped in from disk (/s).
*so: memory swapped to disk (/s).
*IO
*bi: Blocks received from a block device (blocks/s).
*bo: Blocks sent to a block device (blocks/s).
*System
*in: number of interrupts per second, including the clock.
*cs: number of context switches per second.
*CPU – These are percentages of total CPU time.
*us: Time spent running non-kernel code. (user time, including nice time)
*sy: Time spent running kernel code. (system time)
*id: Time spent idle. Before Linux 2.5.41, this includes IO-wait time.
*wa: Time spent waiting for IO. Before Linux 2.5.41, included in idle.
*st: Time stolen from a virtual machine. Before Linux 2.6.11, unknown.
The top command is useful to check memory and CPU usage per process. It displays information about:
*uptime
*average load
*tasks running
*number of users logged in
*number of CPUs/CPU utilization
*memory/swap system processes
The data is continuously updated, which allows you to follow the processes in real-time.
Aside from providing you with essential memory information, the top command provides a limited interactive interface. It is possible to manipulate and configure operations by using command-line options.
The man top command provides a comprehensive list of all available variations.
The information the htop command provides is similar to the top command. However, the real advantage to the htop command is its user-friendly environment and improved controls.
The command uses color for its output, provides full command lines for processes, as well as the option to scroll both vertically and horizontally.
The following output appears:
*
*The top segment provides summary information and contains graphic meters and text counters.
*The lower section structures the detailed data, per process. This allows you to perform actions on individual processes with ease.
*The shortcuts listed at the bottom of the screen will enable you to manipulate and customize the processes quickly and without the need to type specific commands.
Note: If you run into “Command ‘htop’ not found” message when trying to run the htop command, you will need to install the htop function first:
As an alternative, use the command below:
Using a graphical interface for server administration is not common practice. However, certain data sets are much clearer, with a visual representation of memory usage.
To access the System Monitor:
*Navigate to Show Applications.
*Enter System Monitor in the search bar and access the application.
*Select the Resources tab.
*A graphical overview of your memory consumption in real time, including historical information is displayed.
This guide provided several options to check memory usage on your Linux system. We learned that a single command provides an abundance of valuable data for future analysis. Learning to interpret the information correctly is critical.
Now you can administer your server more efficiently.
