Is it possible to change the RAM on a laptop to a more powerful one? Let's sort through the shelves

Introduction: why the issue of upgrading RAM is relevant in 2026

Modern programs and games place increasingly stringent demands on hardware, and RAM - one of the first components that begins to “slow down” performance. If your laptop has become slower with dozens of browser tabs or new versions Photoshop/AutoCAD, it's time to think about an upgrade. But here a key question arises: Is it possible to replace RAM on a laptop?, or did the manufacturers tightly solder everything inside the case?

The answer is ambiguous: more than 60% of modern ultrabooks (including models Apple MacBook Air, Dell XPS 13 And HP Spectre) have a sealed memory, while gaming and budget laptops often leave room for upgrades. In this article, we will look at how to determine your memory type, which models support replacement, and what to do if the upgrade is not possible. And also - detailed instructions for those who are ready to take up a screwdriver.

How to find out if the RAM in your laptop can be replaced

Before you run to the store for new planks, you need to figure out two things: does your model support memory replacement And what type of RAM is installed. Here are 3 reliable ways to check this:

• 🔍 Official website of the manufacturer. Enter your laptop model (for example, Lenovo ThinkPad T14 Gen 3) in search and find the section Specifications → Memory. Look for phrases like "upgradable", "user-replaceable" or "soldered" (soldered).
• 🛠️ Service manuals. On the sites iFixit or NotebookCheck They often post disassemblies of specific models with photos of the insides. For example, for ASUS ROG Zephyrus G14 It states that one RAM slot is sealed, and the second is removable.
• 💻 Software diagnostics. Utilities like CPU-Z (tab SPD) or HWiNFO will show the number of slots, memory type (DDR4/DDR5) and current frequency. If in the section Memory Only one slot is visible, most likely the second strip is soldered.

Pay special attention to laptops Apple: all MacBook since 2016 (starting from MacBook Pro Touch Bar) have a sealed memory. Among Windows devices, the “untouchable” ones are often ultrabooks labeled "Ultra" or "Slim" (For example, Acer Swift 5 or MSI Prestige 14).

Types of RAM: what can be installed instead of the old one

If your laptop supports upgrading, the next step is to choose compatible memory. It is important to consider here four key parameters:

1. Type (generation). Modern laptops use DDR4 (up to 3200 MHz) or DDR5 (from 4800 MHz). DDR3 found only in older models (before 2017). You can't mix generations!
2. Form factor. 99% of laptops use SO-DIMM (compact version of standard DIMM). The exception is some server laptops (for example, Dell Precision), where it can stand UDIMM.
3. Frequency. It is optimal to choose memory with a frequency supported by processor and chipset. For example, for Intel Core i7-12700H maximum - DDR5-4800, and for AMD Ryzen 7 5800H — DDR4-3200.
4. Volume and number of slats. For dual-channel mode (increases productivity by 10-15%) you need two identical strips. For example, it's better 2x16 GBthan 1x32 GB.

The table below shows the compatibility of memory types with popular processors:

Processor	Supported RAM Type	Max. frequency (MHz)	Max. volume (GB)
11th generation Intel Core i5/i7 (Tiger Lake)	DDR4 or LPDDR4X	3200	64
AMD Ryzen 5000 (Lucienne/Cezanne)	DDR4	3200	64
Intel Core i7/i9 12th generation (Alder Lake)	DDR4 or DDR5	4800 (DDR5)	128
Apple M1/M2	Sealed LPDDR5	6400	24 (M2 Pro/Max)

Important: if your laptop already has LPDDR4/LPDDR5 (often in ultrabooks), it is impossible to replace it - this type of memory is always soldered to the motherboard. You can check the type in CPU-Z on the tab Memory → Type.

Step-by-step instructions: how to replace RAM yourself

If you are convinced that an upgrade is possible, and new strips have already been purchased, it’s time to start replacing. You will need: Phillips screwdriver (usually PH0 or PH1), a plastic spatula (or pick), an antistatic wrist strap (optional), and patience.

Unplug the laptop and remove the battery (if removable)

Work on a non-carpeted desk (avoid static electricity)

Prepare a container for screws (such as a magnetic cup)

Take a photo of the position of the strips before removing them

-->

Step 1: Access the RAM slots. In most laptops, the memory is located under a separate cover on the bottom (often with a RAM icon). In game models (for example, ASUS TUF or Legion) it may be necessary to remove the entire bottom panel. Carefully unscrew the screws and pry off the cover with a plastic spatula.

Step 2. Removing old planks. The RAM strips are secured with latches on the sides. Gently move them apart - the bar will rise at an angle of 30°. Grasp it by the edges (without touching the contacts!) and remove it. If the slot is empty, check it for dust - if necessary, blow it with compressed air.

Step 3: Installing new strips. Insert the memory at the same angle until you hear a click. Press the bar until it snaps into place. Make sure that the contacts are completely seated in the slot - even the slightest misalignment can lead to boot failure.

Step 4. Assembly and testing. Close the lid, tighten the screws and turn on the laptop. If the screen does not light up, check:

• ⚡ Are the strips inserted correctly (try reinstalling).
• 🔌 Is the battery connected (some laptops will not start without it).
• 🖥️ Memory compatibility with the processor (if the laptop beeps, the frequency may not be supported).

After a successful download, check the amount of RAM in Control Panel → System or through CPU-Z. If the system does not see the entire volume, update the BIOS - sometimes firmware is required to support new modules.

What to do if the laptop does not turn on after replacing the RAM?

1. **Remove all the brackets** and try to start - if the laptop beeps, the problem is not in the RAM.

2. **Check one strip** in each slot in turn - this will identify the faulty module or slot.

3. **Reset BIOS**: Remove the CMOS battery (coin on the motherboard) for 10 seconds or use a jumper CLR_CMOS (if any).

4. **Update the BIOS** from a flash drive (instructions are on the manufacturer’s website).

Common mistakes and how to avoid them

Even experienced users sometimes make mistakes when upgrading RAM. Here TOP-5 problems and their solutions:

1. The laptop does not see the new memory.
   ✅ Reason: incompatibility of frequency or type (for example, you are trying to install DDR5 into the slot for DDR4).
   ✅ Solution: Check the motherboard specifications on the manufacturer's website.
2. The system is slower than with the old memory.
   ✅ Reason: single-channel mode is enabled (for example, set 1x32 GB instead of 2x16 GB).
   ✅ Solution: add a second bar or buy a kit of two modules.
3. The laptop randomly turns off under load.
   ✅ Reason: lack of power supply power (relevant for gaming laptops with an upgrade to 64 GB+).
   ✅ Solution: check whether your power supply supports the increased load (information in the manual).

⚠️ Attention: if you upgrade your laptop from Intel 12th generation and older, please note support DDR4/DDR5. Some motherboards (eg. MSI Katana GF66) have two types of slots — you cannot mix planks of different generations!

Another common mistake is ignoring memory timings (signal delays are designated as CL16, CL18 etc.). If the new sticks have higher timings than the old ones, performance may drop. Optimally select memory with lower or equal values (for example, CL16 instead of CL20).

Upgrade alternatives: what to do if the RAM cannot be replaced

If your laptop is one of the 60% of models with sealed memory, don't despair. Here 4 ways to optimize your work without replacing RAM:

• 🔄 Cleaning startup. Disable unnecessary programs in Task Manager → Startup. For example, Discord, Steam And OneDrive can “eat up” up to 2-3 GB of RAM in the background.
• 🖥️ Using the swap file. Set up virtual memory in Control Panel → System → Advanced Settings → Performance → Settings → Advanced. Optimal size - 1.5×[RAM size] (e.g. 24 GB for 16 GB physical memory).
• 🛠️ Lightweight software versions. Replace “heavy” programs with analogues:
  • Photoshop → Photopea (online) or GIMP.
  • Chrome → Firefox with disabled tabs in the background (about:config → browser.tabs.unloadOnLowMemory).
  • MS Office → OnlyOffice or LibreOffice.
• ☁️ Cloud solutions. For resource-intensive tasks (rendering, code compilation), use services like Google Colab, AWS WorkSpaces or Shadow PC (virtual PC with 32 GB RAM for $30/month).

If even these measures do not help, consider purchasing an external GPU (For example, ASUS XG Mobile) - part of the load will be transferred to the video memory, unloading the RAM. Or take a closer look at upgradeable laptops: in 2026, stand out among them Framework Laptop 16 (modular design) and Dell XPS 15 (up to 64 GB DDR5).

FAQ: answers to popular questions

Is it possible to put memory from a PC into a laptop (DIMM instead of SO-DIMM)?

No, this is physically impossible. Planks DIMM (for desktop PCs) are longer and have a different arrangement of keys (cuts). Even if you find an adapter, this will lead to overheating And unstable work due to different voltages (SO-DIMM usually works for 1.2V, and DIMM - on 1.35V).

Is it worth upgrading the RAM in a 2018 laptop?

Depends on the model and tasks:

• ✅ Worth: if you have 8th/9th generation Intel Core or AMD Ryzen 2000/3000, and you use a laptop for work (for example, 16 GB → 32 GB for video editing).
• ❌ Not worth it: if the processor is weak (for example, Intel Core i3-7100U), - the bottleneck will be the CPU, not the RAM.

Check your processor's benchmark for UserBenchmark - if it is in the “red zone” in terms of performance, upgrading the RAM will not give a noticeable increase.

How do I know how much maximum memory my laptop supports?

There are 3 reliable sources:

1. Official documentation. On the manufacturer's website in the specifications section (for example, for Lenovo ThinkPad P1 Gen 4 maximum indicated 64 GB DDR5).
2. Database Crucial. Go to Crucial website, select the laptop model - the system will show the supported maximum.
3. BIOS. Some laptops (eg. HP EliteBook) in section System Information displayed Max Memory Capacity.

⚠️ Attention: Sometimes manufacturers underestimate official limits. For example, Dell XPS 13 9310 according to documentation supports 32 GBbut users install successfully 64 GB (with updated BIOS).

Which is better: one 32 GB stick or two 16 GB sticks?

Two planks 16 GB always preferablebecause:

• 🔹 Turns on dual channel mode, which speeds up memory work by 10-30% (depending on the task).
• 🔹 The load is distributed evenly, reducing the risk of overheating.
• 🔹 If one bar fails, the laptop will continue to work (in single-channel mode).

The only case when one bar is justified is if in a laptop only one slot (for example, in Acer Nitro 5 some modifications have 1 slot + sealed 8 GB).

Is it possible to mix bars of different volumes or frequencies?

Technically you can, but with reservations:

• 🔢 Different volume: will work, but dual-channel mode will only turn on for parts of the same size. For example, 8 GB + 16 GB they will give 8 GB in two-channel and 8 GB in a single channel.
• ⚡ Different Frequency: both strips will operate at the frequency bottom of them. For example, DDR4-2400 + DDR4-3200 = both on 2400 MHz.
• ⏱️ Different timings: the system will select the least optimal (higher CL), which may reduce performance.

Recommendation: if you mix, put bars one manufacturer and series (For example, Corsair Vengeance 16 GB 3200 MHz CL16 + the same, but 32 GB).
