Memory Performance Information
Memory performance information is available from the memory manager through the system performance counters and through functions such as GetPerformanceInfo, GetProcessMemoryInfo, and GlobalMemoryStatusEx. Applications such as the Windows Task Manager, the Reliability and Performance Monitor, and the Process Explorer tool use performance counters to display memory information for the system and for individual processes.
This topic associates performance counters with the data returned by memory performance functions and the Windows Task Manager:

How To Check RAM Details In Windows 10RAM is one of the most crucial factors influencing the speed of your computer. When you notice that your system is running slowly even though you are using a good system and a fast SSD drive, you should probably examine the amount of RAM in your system. What is RAM memory?Random Access Memory, or RAM, is a type of memory that is used by processors to store data that is currently being used. Examples of these include running Operating System files, device drivers, application data, etc. As soon as the computer is powered off, the data in RAM is erased. Checking the complete RAM details using WMIC command
Get RAM details using systeminfo commandHere is another way to find the RAM details for your system through systeminfo command.
Get RAM details using PowerShellIf you want to get complete RAM details, you can use the following PowerShell command: This command will give you a wealth of information about your memory. How do you see how much RAM is in your computer?You can easily check the details of RAM in Windows 10 using the Task Manager. The task manager performance tab shows the majority of memory details including the total amount of RAM, how much is in use, committed/cached and paged/non-paged amount of RAM, RAM speed and frequency, form factor, hardware reserved and even how many slots are being used in the system. To check how much RAM you have on your computer, open the Task Manager by pressing Ctrl + Shift + Esc keys and go to the Performance tab. Select Memory from the left hand pane. The right hand pane will open RAM details. If the RAM usage is more than 90%, you should think of upgrading the RAM capacity in your system, reducing the memory load, and bringing it below 80% for optimal performance. To check how much RAM you have using command-line, open Command Prompt and run the following command: This will show the RAM capacity of all RAM modules separately and in bytes. To check the total RAM capacity in your system, run the following command in Command Prompt: This will show you the total physical memory installed in Megabytes. If you are using PowerShell, you can run the following command to get the RAM size: How to check RAM speed?Windows 10 Task Manager gives the option to check RAM speed with ease. To check RAM speed, open the Task Manager by pressing Ctrl + Shift + Esc keys and go to the Performance tab. Select Memory from the left hand pane. On the right hand page, you should see the Speed of RAM in MHz. Check RAM speed in Task Manager Please note that if you have multiple RAM modules, Windows 10 will report the operating RAM speed which is the lowest of all installed modules. If you want to check the speed of each individual module, just hover your mouse cursor over the slots used. This will show a pop-up with the speed of each module. Speed of each RAM module To check RAM speed using command-line, open Command Prompt and run the following command: This will show the speed of all installed RAM modules. If you are using PowerShell, you can run the following command to check the speed of RAM modules: How do you check what type of RAM you have? DDR3 or DDR4?Unfortunately, the Task Manager doesn’t give very useful information about the RAM type. We can use PowerShell commands to accurately determine the RAM type. To check the RAM type from command-line, open PowerShell and run the following command: This command will give you a number. This number corresponds to the appropriate RAM type. Here are the codes and their corresponding RAM types:
RAM type codes For more information on these codes, you can refer to Microsoft documentation here. You can also use wmic MEMORYCHIP command in Command Prompt to check the memory type: Please note that wmic MEMORYCHIP is an old command and does not always detect the correct RAM type. If you see 0 as a memory type code, it means MEMORYCHIP command was not able to determine the RAM type. Using commands is a very convenient, time-saving method for any task. It is as simple as typing a command and getting the task done. Use the commands I described above to get detailed information about your RAM. Upgrade the RAM if your system is slow or has insufficient RAM, so that all operations will be performed smoothly and rapidly. |
