Type the following command and press Enter: “wmic memorychip get Capacity”
This command will display the capacity of each RAM module installed in your laptop, in bytes. To convert the value to gigabytes (GB), divide the number by 1073741824 (1GB = 1024MB, 1MB = 1024KB, 1KB = 1024 Bytes, so 1GB = 102410241024 bytes = 1073741824 bytes). For example, if the output shows “8589934592,” then you have an 8GB RAM module.
To get the total RAM, you can use this command: “wmic computersystem get totalphysicalmemory”
This command returns the total physical memory in bytes. Divide by 1073741824 to convert the value to GB.
Using PowerShell
PowerShell is another command-line interface that offers more advanced capabilities than Command Prompt.
Open PowerShell by pressing the Windows key, typing “PowerShell,” and pressing Enter. Like Command Prompt, you might need to run PowerShell as administrator.
Type the following command and press Enter: “Get-ComputerInfo | Format-List CsTotalPhysicalMemory”
This command retrieves the total physical memory in bytes. Divide by 1073741824 to convert the value to GB.
Another option is to use this command: “Get-WmiObject Win32_PhysicalMemory | Format-Table Capacity”
This command displays the capacity of each RAM module installed in your laptop, in bytes, similar to the Command Prompt command.
Checking RAM on macOS
macOS offers its own set of tools and methods to determine the amount of RAM installed in your laptop.
Using “About This Mac”
The “About This Mac” window provides a quick overview of your Mac’s hardware specifications, including the amount of RAM.

Type the following command and press Enter: “free -h”
The “-h” option displays the output in a human-readable format (e.g., GB, MB). The output will show the total memory (Mem: total), used memory (Mem: used), and free memory (Mem: free).
Using the “/proc/meminfo” File
The “/proc/meminfo” file contains detailed information about the system’s memory usage.
Open a terminal window.
Type the following command and press Enter: “cat /proc/meminfo | grep MemTotal”
This command displays the total amount of RAM in kilobytes (kB). To convert the value to GB, divide the number by 1048576 (1GB = 1024MB, 1MB = 1024KB, so 1GB = 1024*1024 KB = 1048576 KB).
Using the “dmidecode” Command
The “dmidecode” command decodes the system’s DMI (Desktop Management Interface) data, which includes information about the RAM modules. This method often provides the most detailed information, including the size, type, and speed of each RAM module. You might need root privileges (using “sudo”) to run this command.
Open a terminal window.
Type the following command and press Enter: “sudo dmidecode -t memory”
This command displays detailed information about each RAM module installed in your laptop. Look for entries like “Size” (which indicates the capacity of each module), “Type” (which indicates the RAM type, such as DDR4), and “Speed” (which indicates the RAM speed in MHz).
Interpreting the Results
Once you’ve used one of the methods described above to determine the amount of RAM in your laptop, it’s important to understand what the results mean.
The reported RAM capacity might be slightly lower than the advertised capacity due to reserved memory used by the operating system and hardware. This is normal and doesn’t indicate a problem. For example, a laptop with 8GB of RAM might show only 7.8GB available.
The type and speed of your RAM are also important factors. Faster RAM speeds (e.g., 3200MHz DDR4) generally result in better performance than slower speeds (e.g., 2133MHz DDR4). Make sure to choose the correct RAM type and speed when upgrading.
If you are considering upgrading your RAM, it’s crucial to check your laptop’s specifications to determine the maximum supported RAM capacity and the compatible RAM type. This information can usually be found on the manufacturer’s website or in the laptop’s manual.
Finally, consider your typical usage patterns. If you frequently run multiple applications simultaneously, work with large files, or play demanding games, you’ll benefit from having more RAM. A minimum of 8GB of RAM is generally recommended for most modern laptops, while 16GB or more is recommended for more demanding tasks.

Is it possible to check RAM without booting into the operating system?
Yes, it is possible, although it’s generally more complex. You can access the BIOS or UEFI firmware settings, typically by pressing a specific key (like Delete, F2, F10, or Esc) during startup. The key varies depending on the laptop manufacturer, so check the boot-up screen or your laptop’s documentation for the correct key.
Within the BIOS/UEFI settings, look for a section that displays system information or hardware configuration. The location of this information varies across different BIOS/UEFI versions. You should be able to find details about the installed RAM, including the total amount and sometimes even information about the individual RAM modules. This method requires a bit more technical knowledge but can be useful if you can’t boot into the OS.
How does the amount of RAM affect my laptop’s performance?
The amount of RAM directly impacts your laptop’s ability to handle multiple tasks simultaneously and efficiently. RAM serves as temporary storage for data that your computer is actively using. When you run applications, browse the web, or perform other activities, the data needed for these processes is stored in RAM for quick access. More RAM allows your laptop to handle more processes concurrently without slowing down.
Insufficient RAM can lead to performance bottlenecks, such as slow application loading times, sluggish multitasking, and frequent hard drive access, known as “paging” or “swapping.” This occurs when the system runs out of RAM and starts using the hard drive as temporary memory, which is significantly slower. Therefore, a sufficient amount of RAM is crucial for smooth and responsive performance, especially when running demanding applications or multitasking heavily.
What is the difference between RAM and VRAM?
RAM (Random Access Memory) and VRAM (Video Random Access Memory) are both types of memory used in computers, but they serve different purposes. RAM is the main memory used by the CPU to store data and instructions that are currently being used. It’s essential for running the operating system, applications, and performing general computing tasks. When the CPU needs to access data, it retrieves it from RAM, which is much faster than accessing data from the hard drive.
VRAM, on the other hand, is specifically dedicated to the graphics processing unit (GPU). It stores textures, frame buffers, and other data required for rendering images, videos, and games. The GPU uses VRAM to perform its calculations and display the results on your screen. Higher VRAM capacity allows the GPU to handle more complex graphics and higher resolutions without performance issues, particularly important for gaming and graphics-intensive applications.
Can I upgrade the RAM in my laptop?
Whether or not you can upgrade the RAM in your laptop depends on the specific model. Some laptops have RAM that is soldered directly onto the motherboard, making it impossible to upgrade without specialized equipment and skills. Other laptops have RAM slots where you can easily install or replace RAM modules.
To determine if your laptop’s RAM is upgradable, consult your laptop’s manual or the manufacturer’s website. You can also use online resources like Crucial’s Memory Advisor tool or similar services to identify compatible RAM upgrades for your specific laptop model. If the RAM is upgradable, be sure to purchase the correct type and speed of RAM that is compatible with your laptop’s specifications. Also, remember to take ESD precautions when installing RAM.
How much RAM do I need for my laptop?
The amount of RAM you need depends heavily on how you plan to use your laptop. For basic tasks like web browsing, email, and word processing, 8GB of RAM is generally sufficient for a smooth experience. However, if you plan to run more demanding applications like photo or video editing software, play modern video games, or perform heavy multitasking, 16GB of RAM is recommended.
For professional users who work with very large files, run virtual machines, or engage in intensive tasks like 3D rendering, 32GB or even 64GB of RAM may be necessary. Consider your current and future needs when determining the appropriate amount of RAM for your laptop. It’s generally better to have slightly more RAM than you think you need, as it can significantly improve performance and prevent bottlenecks.
