How to increase RAM in a laptop: a complete guide from selection to installation

Has your laptop started to slow down when working with several programs at the same time? Video editing with delays, and modern games refuse to launch? The reason may lie in the shortage random access memory (RAM). Adding additional RAM sticks is one of the most effective upgrade methods, which will significantly speed up the operation of the device without replacing the processor or video card.

In this article you will find step by step instructions to increase memory in a laptop - from determining the compatibility of modules to their physical installation and testing. We'll look at how to choose the right planks for Lenovo ThinkPad, ASUS ROG, HP Pavilion and other popular models, what tools are needed, and what to pay attention to so as not to damage the device. And if you've never disassembled a laptop, don't worry: our guide is also designed for beginners.

1. How to check if you can increase the memory in your laptop

Not all laptops support RAM upgrades. Manufacturers of some ultrabooks (for example, Apple MacBook Air or Dell XPS 13) solder the memory to the motherboard, making it non-removable. Before purchasing new modules, make sure that your model allows you to replace or add them.

There are three ways to check:

• 🔍 Manufacturer's documentation. Find the technical specifications of your model on the official website. Look for sections Memory, RAM or Upgrade Options. For example, for Lenovo Legion 5 states: "Up to 32 GB DDR4 (2 SO-DIMM slots)."
• 💻 Windows Task Manager. Click Ctrl + Shift + Esc, go to the tab Performance → Memory. The bottom right corner will indicate how many slots are in use (for example, "2 of 4").
• 🛠️ Diagnostic programs. Utilities like CPU-Z (tab SPD) or HWiNFO will show the current modules, their type, frequency and free slots.

⚠️ Attention: If Task Manager shows "1 of 1" slots, it doesn't always mean the memory is soldered. Some laptops (eg. MSI Modern 14) the second slot can be hidden under thermal pads. Check this in the service manual.

Also note maximum supported amount of RAM. For example, laptops with chipsets Intel 10th generation often limited to 64 GB, and models with AMD Ryzen 4000 can support up to 128GB. Exceeding the limit will result in the system simply not seeing the extra memory.

2. How to choose compatible RAM: 5 key parameters

Even if your laptop supports the upgrade, incorrectly selected modules may not work or cause conflicts. When choosing RAM, consider:

Parameter	What does it mean	How to check
Memory type	DDR3, DDR4 or DDR5. DDR4 - the most common standard for laptops 2016–2023.	B CPU-Z on the tab Memory or in the laptop documentation.
Form factor	For laptops - SO-DIMM (short planks). Desktop DIMM won't fit!	Inscription on old modules or in specifications.
Frequency	Measured in MHz (for example, 2400, 3200). Choose frequency no higher, than the processor supports.	B CPU-Z on the tab SPD (field Max Bandwidth).
Voltage	The standard voltage for DDR4 is 1.2V. Modules with 1.35V (DDR4L) are compatible, but less energy efficient.	On the trim label or in the specifications.
Rank	Single Rank (peer-to-peer) is cheaper, Dual Rank (two-rank) is more productive. For gaming and rendering, Dual Rank is better.	In the module specifications (for example, 1Rx8 — Single Rank).

Example: for laptop ASUS TUF Gaming A15 (2021) with processor Ryzen 7 5800H modules will fit DDR4 SO-DIMM with frequency 3200 MHz, voltage 1.2V and volume up to 32 GB (2x16 GB). If you install sticks with a frequency of 3600 MHz, they will operate at 3200 MHz (according to the processor limitation).

Brand Advice: among reliable manufacturers - Crucial, Kingston, Samsung, Corsair And G.Skill. Avoid no-name modules: they may not meet their stated specifications and cause blue screens (BSOD).

3. Tools and preparation for installation

To replace RAM in a laptop you will need:

• 🔧 Screwdriver. Usually a cross (PH0 or PH1), but some models (for example, MacBook Pro) require a special "asterisk" (T5).
• 🧲 Antistatic bracelet. Protects components from static electricity. If it is not there, touch the metal case of the system unit before starting work.
• 📦 Plastic spatula or pick. It will help to carefully open the case latches (especially for HP Spectre or Acer Swift).
• 📸 Smartphone. Take photos of the location of the screws and modules before disassembling - this will make reassembly easier.

Also prepare your workplace:

• 🪑 Work at a table with good lighting.
• 🧹 Remove carpets and woolen fabrics - they accumulate static electricity.
• 🔌 Disconnect the laptop from the network and remove the battery (if it is removable).

⚠️ Attention: If your laptop is under warranty, replacing the RAM yourself may void it. Check this with the manufacturer. For example, Lenovo And Dell often allow memory upgrades without voiding the warranty, and Apple - no.

4. Step-by-step instructions: how to physically install memory in a laptop

The installation process depends on the design of the laptop. We will consider two options: with separate cover for RAM (like MSI GF63) and with complete disassembly of the case (like MacBook Pro or HP Envy).

Option 1: Laptop with a separate memory cover (the simplest case)

This design is typical for gaming and business laptops (Lenovo ThinkPad, ASUS ROG Strix). Proceed like this:

1. Turn the laptop over and look for the lid with the memory icon (usually marked as RAM or Memory).

2. Remove the screws (they may be hidden under the rubber feet). On some models (Acer Predator) the lid is secured with latches - pry it off with a plastic spatula.

3. If the slots are occupied, carefully move the latches on the sides of the bar (they will snap open with a characteristic sound). The module will rise on its own at an angle of 30° - pull it out.

4. Insert the new strip at a 30° angle, aligning the notch on the contacts with the protrusion in the slot. Press until the latches click.

Option 2: Laptop with a non-separable case (difficult case)

Ultrabooks (Dell XPS 15, Huawei MateBook) often require complete disassembly. It is important here not to damage the cables and thermal pads. General algorithm:

1. Unscrew all the screws on the bottom cover (they can be of different lengths - remember where each one was!).

2. Using a plastic spatula, carefully pry the lid off, starting at the corner. On some models (MacBook Air) the body is glued - use a hair dryer to soften the glue.

3. Disconnect the battery cable (usually it is covered with black electrical tape). This will prevent short circuit.

4. Locate the RAM slots (they may be under a metal shield or thermal pad). Further actions are the same as in option 1.

Critical detail: In laptops with soldered memory (e.g. Apple M1/M2) there are no physical slots for RAM. Trying to find them will only damage the motherboard.

What to do if the RAM slot latches are broken?

If the plastic latch breaks off, do not try to install the module without fixing it - it may fall out due to vibration. Temporary solution: fix the strip with a drop of hot glue (don't overdo it!). For permanent repair, replace the slot or contact service.

5. Setting up BIOS and checking new memory

After installing the modules, turn on the laptop and check if the system recognizes the new memory. To do this:

1. Click Del, F2 or Esc (depending on the model) when loading to enter BIOS/UEFI.

2. Find a section System Information or Memory Settings. Make sure the correct volume is displayed (eg 16GB (8GBx2)).

3. If memory is not detected:

   • Check that it is firmly inserted into the slot.
   • Update the BIOS to the latest version (instructions on the manufacturer's website).
   • Try swapping modules.

On Windows, check memory via:

• 🖥️ Start → Settings → System → About (section Device characteristics).
• 🔧 Task Manager → Performance → Memory.
• 📊 Utility MemTest86 for testing for errors (runs from a flash drive).

⚠️ Attention: If the laptop does not turn on after installing RAM (black screen, blinking lights), this may indicate incompatible modules or damaged contacts. Remove the new sticks and check if the system boots with the old ones.

6. Common mistakes and how to avoid them

Even experienced users sometimes make mistakes when upgrading RAM. Here are the most common:

• ❌ Buying memory with the wrong voltage. For example, modules DDR4L (1.35V) into a laptop designed for DDR4 (1.2V). This may cause overheating.
• ❌ Ignore dual channel mode. If you have 2 slots, install the slots in pairs (for example, 2x8 GB instead of 1x16 GB) - this will double the throughput.
• ❌ Use of excessive force. RAM slots are fragile! If the module does not go in easily, check that it is oriented correctly.
• ❌ Forgetting to update the BIOS. Older firmware versions may not support new modules (relevant for 2018–2019 laptops).

If after installation there are BSOD (blue screens) with errors MEMORY_MANAGEMENT or IRQL_NOT_LESS_OR_EQUAL, this is a sign:

• Module incompatibility (different frequencies or ranks).
• Poor contact (try reinstalling the strips).
• Defective memory (test modules separately).

In such cases, return the old strips and contact the service center for diagnostics.

7. Is it worth increasing the memory or is it better to buy a new laptop?

Upgrading RAM is not always justified. Here's when it makes sense:

• ✅ The laptop is 2-4 years old, and the remaining components (processor, video card) are still relevant.
• ✅ You use resource-intensive programs: Adobe Premiere, AutoCAD, VMware.
• ✅ Current memory capacity is 4-8 GB, but you want 16-32 GB.

When is it better? don't spend money on an upgrade:

• ❌ The laptop is more than 5 years old, and it slows down due to a weak processor (for example, Intel Core i3-7100U).
• ❌ The memory is soldered to the motherboard (as in MacBook Air M1).
• ❌ The cost of new modules exceeds 30% of the price of a new laptop.

Example: if you have HP Pavilion 15 2020 from Ryzen 5 4500U and 8 GB of memory, adding another 8 GB will cost ~3,000 rubles and will give a performance increase of 30–40%. But for Lenovo IdeaPad 3 2017 from Core i3-7020U Upgrading RAM will not solve problems with slow operation - it is better to buy a new device.

FAQ: Answers to frequently asked questions

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

No, this is physically impossible. Modules DIMM (for desktops) are longer and have a different connector. Can only be installed on laptops SO-DIMM.

Which is better: one 16 GB stick or two 8 GB sticks?

Two 8 GB sticks are preferable, as they work in two-channel mode, doubling memory bandwidth. This is especially noticeable in games and rendering applications.

How do I know what maximum memory capacity my laptop supports?

Methods:

1. View specifications on the manufacturer's website.
2. Use the utility Crucial System Scanner (scans the system and shows compatible modules).
3. Google your laptop model with the query "maximum amount of RAM".

Is it possible to mix memory from different manufacturers?

Technically yes, but it is fraught with problems. If the slats have different frequencies or timings, the system will select the slowest settings. It is better to use modules from one kit (kit).

Do I need to update the BIOS after installing new memory?

Updating the BIOS is recommended if:

• New modules are not defined.
• The laptop was released more than 2 years ago (the firmware may not support modern memory standards).
