How to Determine if Your Laptop Uses DDR3 or DDR4 RAM: A Comprehensive Guide

Having trouble figuring out whether your laptop is running on DDR3 or DDR4 RAM? This guide provides you with several methods to identify the type of RAM you have, ensuring you can make an informed decision about timing, capacity, and performance. Regardless of whether you're a tech-savvy user or a novice, this article will equip you with the knowledge needed to diagnose your system. Let's dive in!

Methods to Identify DDR3 vs DDR4 RAM

1. Check System Information

A straightforward way to determine your RAM type is by checking your system information. Here’s how:

Windows: Press Win R, type msinfo32, and hit Enter. Look for details about your RAM version macOS: Click the Apple logo in the top-left corner and select “About this Mac”. Then, click on “System Report”. Inside the “Memory” section, you’ll see the RAM type

2. Use Third-Party Tools

For more detailed information, consider using third-party tools:

CPU-Z: Download and install CPU-Z to get comprehensive details about your RAM, including its type Speccy: This tool also provides detailed information about your hardware, including RAM type

3. Consult Laptop Specifications

Another reliable method is to consult your laptop’s specifications. Look up your laptop model on the manufacturer's website or in the user manual, where you can find the type of RAM mentioned.

For example, if your laptop model is a Dell XPS 13, you can easily find the details on the Dell official site. It’s a straightforward process and can save you the trouble of diving into your system.

4. Physical Inspection (Advanced)

If you're comfortable opening your laptop, you can inspect the RAM sticks directly:

Open your laptop carefully, as some models require specific tools. Examine the RAM sticks for any labels indicating the type, such as DDR3 or DDR4. Note the physical characteristics: DDR3 RAM has a notch at the 5th position, while DDR4 RAM has two notches around positions 7 and 8.

The wrong generation of RAM won’t fit into your RAM slot due to size and physical placement differences.

Additional Tips for Determining RAM Type

5. Check RAM Sticker

Often, a label on the RAM module will indicate the RAM type. Additionally, the notch position and height can help you determine the type. A notch in the 5th position points to DDR3, while two notches around positions 7 and 8 indicate DDR4.

6. Use Frequency to Identify RAM Type

Another simple method is to check the frequency of your RAM:

DDR3 frequency generally tops at 1600 MHz, whereas DDR4 starts from 1866 MHz.
