Random-access memory is a form of computer memory that can be read and changed in any order, typically used to store working data and machine code. In this writing, ways to view computer memory (RAM) of window system and Ubuntu Linux system. How to view Random-access memory (RAM).
Open the system window. You can use multiple methods to quickly open this window. Firstly, press the Win+Pause key combination, which will open the system window. Second, open the start menu and right-click “Computer”. Select “Properties” to open the system window. After that, open the start menu, select “Settings”, then “System”, and then click “About” (Windows 10 system).
After that, find the “installed memory (RAM)” item.
It will tell you the amount of memory installed and the amount of available memory recognized by Windows.
Note: The “Available Capacity” item under the “Installed Memory” capacity. Because the computer hardware reserves part of the memory for its own use, Windows cannot use this part of the memory, so the amount of available memory in Windows will be less than the amount of installed memory. For example, when you install 8 GB of memory, Windows can only recognize and use up to 7.88 GB of available memory.
Use the command prompt to understand the details of the memory.
If you want to know more information about memory, such as operating speed or capacity of each component, you can use the command prompt to get more detailed information.
Open a command prompt from the start menu. You can also press Win+R to open the run box, and then enter cmd to start it.
Enter the command ‘wmic MEMORYCHIP get BankLabel, DeviceLocator, Capacity, Speed’ and press the Enter key. Several columns of information will then be displayed.
The BankLabel column will tell you which slot the memory module is installed in. The Capacity column will display the capacity of each memory stick, measured in bytes. The DeviceLocator column is another way to display the memory installation location. The Speed column will tell you the operating speed of each memory bank.
View the current memory usage. You can use Task Manager to view the current computer memory usage. Press Ctrl+Shift+Esc to open the task manager.
Click on the “Performance” tab. If you don’t see this tab, please click the “Details” option at the bottom of the window.
Select the “Memory” option (Windows 8 and later) and this will allow you to view memory usage.
Ubuntu Linux system
Open the terminal. You can use the system information window to view the memory information. However, the terminal can be used to view it more quickly and conveniently. You can press Ctrl+Alt+T to open the terminal.
This method is suitable for Ubuntu Linux system, but it should also be effective in other Debian systems.
Type .free -m and press Enter. This will read and display the basic information of the installed memory.
Find the amount of installed memory
Used memory, and available memory. The free -m command will display information about memory usage
The Total column will display the total amount of installed memory in MB. This may deviate from the capacity indicated on the memory stick. For example, an 8 GB memory stick will display 7997 MB installed capacity.
The Used column will display the current memory usage, and the Free column will display the available memory capacity. Memory is supposed to be used, so even if you see that the computer has used most of the memory, don’t worry about it.
Learn why Ubuntu does not display all the memory. Since there may be several reasons why Ubuntu cannot display all the memory you have installed:
If your operating system is 32-bit, Ubuntu can only recognize up to 4 GB of memory. Therefore, no matter how large and large the memory stick is, it will not help.
After that, check whether all memory modules are running at the same speed.
Mismatched memory modules will cause system problems and various malfunctions.
Finally, make sure to insert the memory module. The Linux system cannot recognize the memory correctly If do not plug in the memory stick.
Above all, there is how to view Random-access memory (RAM) of the window system and Ubuntu Linux system.
