Can You Upgrade the RAM in Your Laptop?

Not every laptop lets you swap out the RAM. A lot of modern ultrabooks and all MacBooks with Apple Silicon have memory soldered straight to the motherboard. That means you’re stuck with whatever shipped from the factory. Before spending any money, check whether your specific laptop has accessible RAM slots.

The fastest way to find out is to look up your laptop model on Crucial’s System Scanner or the manufacturer’s spec sheet. Search for “maximum memory” and “memory slots” in the specifications. If it says “onboard” or “soldered,” the RAM isn’t upgradeable. If it lists SO-DIMM slots (usually 1 or 2), you’re good to go.

How to Check Your Current RAM

Before you buy new memory, you need to know what’s already installed: how much, what type, and what speed. This makes sure you buy something compatible.

On Windows

1. Press Ctrl + Shift + Esc to open Task Manager.
2. Click the Performance tab.
3. Select Memory from the left panel.
4. Note the total RAM, speed (e.g., 2400 MHz), form factor (SO-DIMM), and slots used.

The “Slots used” field is the one that matters most here. If it shows “2 of 2” and both slots are occupied, you’ll need to pull out the existing sticks and replace them with bigger ones. If it shows “1 of 2,” you can just add a second stick to the empty slot.

On macOS

1. Click the Apple menu and select “About This Mac.”
2. Look at the Memory line for total RAM and type.
3. For detailed info, click “System Report” then “Memory” in the sidebar.

If you’re on an Apple Silicon Mac (M1, M2, M3, M4), the System Report shows “Unified Memory” and no slot information. That’s because the memory is part of the chip itself and can’t be upgraded. Intel-based MacBooks from 2012 and earlier had upgradeable RAM slots, but those are pretty rare at this point.

What Type of RAM Does Your Laptop Need?

Laptop RAM uses the SO-DIMM form factor, which is roughly half the size of desktop RAM (DIMM). Beyond the physical size, you need to match three things: generation, speed, and voltage.

DDR4 and DDR5 are not interchangeable. The notch position on the module is different, so a DDR5 stick physically won’t fit in a DDR4 slot. Most laptops from 2020 to 2023 use DDR4. Laptops from late 2022 onward increasingly ship with DDR5. Check Task Manager or your laptop’s spec sheet to confirm which generation you need.

How Much RAM Should You Add?

For everyday use like browsing, office work, and streaming, 8 GB total is the minimum you want in 2026. Going from 4 GB to 8 GB gives you the most noticeable improvement. Jumping from 8 GB to 16 GB helps if you regularly juggle lots of browser tabs, run virtual machines, or edit photos and video. Going beyond 16 GB to 32 GB benefits video editors, 3D artists, developers running multiple environments, and anyone working with large datasets.

If your laptop has two RAM slots, use two identical sticks (same brand, same speed, same capacity). This turns on dual-channel mode, which roughly doubles memory bandwidth compared to a single stick. Two 8 GB sticks will outperform a single 16 GB stick in tasks that depend on memory bandwidth.

How to Install RAM in Your Laptop

This takes about 10 to 15 minutes and you’ll need a small Phillips screwdriver. Some laptops also need a plastic spudger or guitar pick to pry open the bottom panel. Work on a clean, static-free surface. A wooden desk is fine. Avoid carpet.

1. Shut down your laptop completely (not sleep mode) and unplug the power adapter.
2. Close the lid and flip the laptop upside down.
3. Remove the bottom panel screws. Some laptops have a dedicated RAM access panel (a smaller cover held by one or two screws). Others require removing the entire bottom panel.
4. Before touching any internal components, ground yourself by touching an unpainted metal surface on the laptop chassis. This discharges static electricity that could fry components.
5. Find the RAM slots. They’re usually near the center of the board, sometimes covered by a thin metal shield.
6. To remove an existing stick, push the clips on each side of the slot outward. The RAM module pops up at about a 30-degree angle. Slide it out gently.
7. Line up the notch on your new RAM module with the notch in the slot. Insert it at a 30-degree angle and push firmly until the gold contacts are fully seated.
8. Press the module down flat until the side clips snap into place. You should hear two clicks.
9. Replace the bottom panel and screws.
10. Power on your laptop and check Task Manager (or About This Mac) to confirm the new RAM is recognized.

If the laptop doesn’t boot after installation, power it off, reseat the RAM modules (remove and reinsert them), and try again. A failed boot usually means the module isn’t fully seated in the slot.

What If Your Laptop Doesn’t Recognize the New RAM?

A few things can cause this. The most common is an incompatible module: wrong generation (DDR4 vs DDR5), wrong speed, or a capacity larger than what the laptop’s chipset supports. Some older laptops max out at 8 GB or 16 GB even if the slot physically accepts a 32 GB stick.

Try these steps if the new RAM isn’t showing up or the laptop won’t start:

1. Reseat the module. Remove it and firmly reinsert it.
2. Test each stick individually to figure out if one module is faulty.
3. Update your BIOS to the latest version (check the manufacturer’s support page for your model).
4. Confirm the total RAM doesn’t exceed your laptop’s documented maximum.

If you’re mixing an old stick with a new one, the system will run both at the speed of the slower module. A 2400 MHz stick paired with a 3200 MHz stick means both run at 2400 MHz. For the best performance, use two identical modules.

Laptops That Don’t Allow RAM Upgrades

The push toward thinner, lighter designs has led many manufacturers to solder RAM directly to the motherboard. Here’s a rough guide to what you’ll find across the major brands.

Apple MacBooks (all models since 2013), Microsoft Surface Laptop, Dell XPS 13 and 15 (recent generations), HP Spectre x360, and most ultrabooks under 3 pounds use soldered RAM. Gaming laptops from ASUS, MSI, Lenovo Legion, and Acer Predator almost always have upgradeable SO-DIMM slots since they prioritize performance over thinness. Business laptops like the Lenovo ThinkPad T-series and HP EliteBook typically offer at least one user-accessible RAM slot.

Is it better to upgrade RAM or buy a new laptop?

If your laptop is otherwise working fine and just feels sluggish with too many tabs or apps open, a RAM upgrade is the cheapest fix. An 8 GB stick costs $20 to $35. Compare that to a new laptop at $400 or more. Upgrading makes less sense if the laptop is over 6 years old, has a slow mechanical hard drive (replace that with an SSD first), or has other hardware problems like a dying battery.

Can you mix different RAM brands?

Technically yes, as long as the generation (DDR4/DDR5), speed, and voltage match. Mixing brands can occasionally cause stability issues, but it usually works fine. For guaranteed compatibility and dual-channel performance, buy a matched pair from the same manufacturer. Kits from Crucial, Kingston, Corsair, and G.Skill are widely available and come pre-tested as pairs.

Will upgrading RAM void my warranty?

For most laptop brands, no. Lenovo, Dell, HP, and ASUS consider RAM and SSD upgrades to be user-serviceable. Their warranties specifically exclude damage to components you install yourself, but they don’t void the warranty on the rest of the laptop. Apple is the exception. Opening a MacBook yourself can void your AppleCare coverage. Always check your specific warranty terms before opening the chassis.
