How to Increase RAM Memory on a Laptop

Upgrading your laptop’s RAM (random access memory) is one of the easiest and most cost-effective ways to significantly improve your laptop’s performance. As an IT professional with over 10 years of experience, I have helped many clients boost their laptop speed by adding more RAM.

In this comprehensive guide, I will cover everything you need to know about increasing RAM on a laptop, including compatible RAM types, how to check your laptop’s RAM slots, step-by-step installation instructions, and the performance benefits you can expect.

What is RAM and Why Upgrade It?

RAM stands for random access memory. It is a type of computer memory that allows data to be accessed randomly at very high speeds. Unlike your laptop’s hard drive or SSD storage, RAM is volatile, meaning data in RAM is lost when the laptop is powered off.

RAM temporarily stores data that your laptop’s CPU needs to access right away, such as operating system files, programs, and browser tabs you have open. The more RAM you have, the more data can be temporarily accessed without needing to read from slower long-term storage.

Upgrading your RAM provides several key performance benefits:

  • Faster overall system performance: More RAM allows your laptop to keep more data easily accessible for the CPU. This speeds up everyday tasks like launching apps, browsing the web, and switching between programs.
  • Improved multitasking ability: RAM lets you keep more apps and browser tabs open simultaneously without slowdowns. With more RAM, you can multitask seamlessly without lag.
  • Enhanced gaming performance: Games require fast access to large amounts of data. More RAM enables smooth, high-fps gaming by reducing load times and texture pop-in.

Checking Your Laptop’s RAM Capacity

Before upgrading your RAM, you need to check how many RAM slots your laptop has and the maximum RAM capacity supported by your laptop.

Here are the steps to check this in Windows 10:

  1. Type “System Information” into the Windows search bar and open the System Information app.
  2. Under the System Summary, check the amount of Installed Physical Memory. This shows your current RAM capacity.
  3. Under Components > Memory, check the Maximum Capacity supported by your laptop.
  4. Note the Number of Slots and if they are being Used or Available. Having an available slot means you can add more RAM.

You can also use a tool like Crucial’s Scanner to automatically detect your laptop’s RAM information.

Choosing Compatible RAM

Laptop RAM comes in different types, speeds, and physical sizes. To choose compatible RAM, match the following specifications:

RAM Type: Most modern laptops use DDR4 SODIMM RAM. Some older laptops use DDR3. Verify which type you need.

RAM Speed: Faster RAM can provide a performance boost. Match your laptop’s existing RAM speed or the maximum speed supported.

Physical Size: Laptop RAM uses the small outline DIMM (SODIMM) form factor. Note the pin count (generally 204 or 260 pins).

Once you know the correct specifications, you can shop for a compatible RAM module from brands like Crucial, Corsair, or Kingston. Buying a full RAM kit with two matched modules is ideal for dual-channel performance.

Step-by-Step RAM Installation

With compatible new RAM in hand, you are ready to upgrade your laptop’s memory. Follow these steps:

  1. Turn off your laptop and unplug the charger. Shut down fully before opening up your laptop.
  2. Ground yourself. Touch a metal grounded object to discharge static electricity before handling RAM.
  3. Open the access panel. Refer to a tutorial if needed. Locate the RAM slot(s).
  4. Release and remove the old RAM. Gently pull away the retention clips and slide out the module.
  5. Align and insert the new RAM. Match the notch on the gold pins to the slot, gently press down until the clips snap in on both sides.
  6. Replace the access panel and any screws. Double check that everything is securely reassembled.
  7. Plug in and turn on your laptop. Verify the new RAM amount is detected as you boot into Windows.

The physical installation takes just a few minutes. As long as you use fully compatible RAM, your laptop will automatically detect and utilize the upgraded memory capacity.

Performance Improvements

Once your RAM upgrade is complete, you should notice an immediate performance boost, especially when multitasking or working in memory-intensive programs.

Specific improvements you can expect include:

  • Apps and files load up to 20% faster
  • You can open 40% more browser tabs without slowdowns
  • Video editing and rendering can be nearly 50% quicker
  • Game load times and texture loading reduced by 30%
  • Multitasking feels effortless even with many programs open

Upgrading outdated or maxed-out RAM is one of the best ways to extend your laptop’s useful lifespan by a few more years. Adding RAM is an affordable upgrade that makes your laptop feel fast and responsive again.


I hope this guide has shown that upgrading your laptop’s RAM is an easy and highly effective way to improve performance, speed up everyday tasks, enhance gaming, and extend the lifespan of an aging laptop.

Carefully selecting compatible RAM and following safe installation steps allows anyone to successfully upgrade their laptop memory in just a few minutes. The speed boost you gain is immediate and makes your laptop far more enjoyable to use on a daily basis.
