RAM upgrade myths & realities: Can you boost your laptop?

Many customers come into my workshop complaining that their laptop feels sluggish, hoping a simple RAM (Random Access Memory) upgrade will make it run like new. There is a common belief that more memory automatically equals more speed.

While additional RAM is one of the most effective hardware upgrades you can perform, there is a lot of misinformation out there about what it actually does and whether your memory is actually upgradeable.

Let's look at the realities of laptop RAM upgrades.


Myth 1: "More RAM will make my laptop twice as fast"

RAM acts as your computer's temporary short-term memory. It holds the active files and data for open applications like Safari, Word, or Chrome tabs so the CPU can read them instantly.

  • The Reality: RAM acts like a desk. If your desk is piled high with folders and you run out of space, your work slows down as you shuffle things inside storage drawers. Adding more RAM gives you a bigger desk so you can have more folders open at the same time.
  • The Catch: If you only ever have three Chrome tabs and Word open, your desk is already big enough. Going from 8GB to 16GB won't provide any noticeable speed boost because you aren't bottlenecking your RAM. A slow laptop with adequate memory is usually suffering from a slow hard drive or processors, not a lack of RAM.

Myth 2: "Every laptop can be upgraded"

Ten years ago, almost every Apple or Windows laptop shipped with standardised memory slots, allowing you to pop open the bottom cover and slide fresh memory sticks inside.

  • The Reality: To make modern laptops incredibly thin, lightweight, and power-efficient, manufacturers now permanently solder the RAM chips directly onto the main motherboard. This is standard on every Apple Silicon MacBook (M1, M2, M3) and most ultra-slim Windows PCs (like the Microsoft Surface).
  • The Catch: If your laptop has soldered memory, it is physically impossible to upgrade. What you buy on day one is what you are stuck with for the life of the machine.

Realities of RAM upgrades: What to check first

If your machine is lagging during multitasking, check your real memory pressure before spending cash on hardware.

On Windows:

  1. Press Ctrl + Shift + Esc to open Task Manager.
  2. Select the Performance tab and click on Memory.
  3. Look at your memory consumption. If your memory use is constantly resting above 85% or shows heavy "paging" to your hard drive, an upgrade will provide a massive, noticeable difference.

On Mac (Intel-based models only):

  1. Open Activity Monitor (via Spotlight or Utilities).
  2. Select the Memory tab at the top.
  3. Look at the Memory Pressure Graph at the bottom. Green means you have plenty of room; Yellow means your desk is getting full; Red means your Mac is out of memory and swapping files to your drive, indicating it is time to upgrade.

Get an honest assessment

Before purchasing random RAM sticks online, bring your laptop to my shop. I can check your exact model number to see if your memory is upgradeable, recommend the correct speed and capacity to prevent hardware crashes, and fit clean, fully compatible chips for you.
