Checking if your RAM is DDR3 or DDR4 on a Windows 11 computer is straightforward. Begin by using the Task Manager to find out your memory type. If you need more detailed information, you can use third-party software like CPU-Z. These tools will help you determine your RAM type by inspecting your system’s hardware specifications.
How to Check if RAM is DDR3 or DDR4 on Windows 11
In this section, we’ll guide you through the process of finding out whether your computer’s RAM is DDR3 or DDR4 using simple steps.
Step 1: Open Task Manager
Press “Ctrl + Shift + Esc” to open Task Manager.
Task Manager is a handy tool for monitoring your system’s performance. You can also open it by right-clicking on the Start button and selecting “Task Manager” from the menu.
Step 2: Go to the Performance Tab
Click on the “Performance” tab at the top of Task Manager.
The Performance tab provides valuable information about your CPU, memory, and other components. Here, you’ll find details about your RAM’s usage and type.
Step 3: Select Memory
Click on “Memory” in the left sidebar.
Selecting Memory will give you specific details about your RAM, such as its speed, form factor, and more. However, note that it might not always specify DDR3 or DDR4.
Step 4: Use CPU-Z for Detailed Info
Download and install CPU-Z for more detailed RAM information.
CPU-Z is a third-party tool that provides in-depth details about your system’s hardware, including the specific type of RAM you have installed.
Step 5: Run CPU-Z and Check the Memory Tab
Open CPU-Z and navigate to the “Memory” tab to find your RAM type.
The Memory tab in CPU-Z will explicitly state whether your RAM is DDR3 or DDR4, giving you a clear answer to your query.
Once you’ve completed these steps, you’ll know exactly what type of RAM is installed in your Windows 11 computer. Having this information can be helpful if you’re planning to upgrade your RAM or troubleshoot system issues.
