How to check how much memory a computer has

When using your computer on a daily basis, understanding your computer's memory (RAM) capacity is critical to judging its performance and ability to handle multitasking. Whether you are upgrading memory, running large software, or solving system lags, knowing how to check memory is essential. This article will introduce in detail how to check the memory capacity in Windows and macOS systems, and provide a structured display of related data.

1. How to check memory in Windows system

In Windows systems, there are many ways to check the memory capacity. The following are some common methods:

1. View through Task Manager

Press shortcut keyCtrl + Shift + EscOpen the task manager and switch to"Performance"tab, select"memory", you can see the total capacity, used amount and available amount of memory.

2. View through system information

pressWin+ROpen the run window and entermsinfo32and press Enter. In the system information window, find"Installed physical memory (RAM)", you can see the total memory capacity.

3. View through command prompt

Open the command prompt (CMD), enter the following command and press Enter:

wmic memorychip get capacity

This command will display the capacity of each memory module in bytes, which needs to be manually converted to GB.

2. How to check memory in macOS system

In macOS system, checking the memory is also very simple:

1. View through "About This Mac"

Click in the upper left corner of the screenapple icon, select"About this Mac", you can see the total memory capacity on the overview page.

2. View via Activity Monitor

openApplications > Utilities > Activity Monitor, switch to"memory"tab to view memory usage and total capacity.

3. Common specifications of memory capacity

The following is the current mainstream memory capacity specification table for reference:

4. How to determine whether memory needs to be upgraded

If your computer frequently freezes, programs respond slowly, or you frequently receive insufficient memory prompts, it may be caused by insufficient memory capacity. The following are several indicators to determine whether you need to upgrade memory:

1. The memory usage exceeds 80% for a long time.

2. The system slows down significantly when running large software.

3. Frequent crashes or freezes when multitasking.

5. Hot topics and content in the past 10 days

The following are technology-related topics that have been hotly discussed across the Internet recently, which may be related to memory upgrades or computer performance optimization:

6. Summary

Checking your computer's memory capacity is the first step in optimizing system performance. Whether you are a Windows or macOS user, you can quickly obtain memory information through the system's built-in tools. If you find that the memory is insufficient, you can choose an upgrade plan based on actual needs. The recent popularity and price drop of DDR5 memory have provided more choices for installed users, and the Windows 11 update has further optimized memory management efficiency.

I hope this article can help you easily master the method of checking computer memory, and provide a reference for subsequent hardware upgrades or system optimization!
