Modern laptops from the brand MSI They have high performance, but over time the loads grow, and the built-in memory becomes insufficient for the comfortable operation of heavy applications, games or system software. Many users are faced with the need to expand RAM (RAM) to avoid lags and freezes during device operation. Upgrade procedure on models MSI has its own specific features, which are important to consider before starting work.
Not all models are equipped with slots for independent expansion, and some series require complete replacement of modules. If you are planning an upgrade, you need to know exactly the type of memory supported, the frequency and the maximum amount that can handle memory controller your processor. The wrong choice of components can lead to unstable operation of the system or the inability to boot the operating system.
Checking compatibility and selecting modules
Before you go to the store, you should study the characteristics of your device in detail. Most modern laptops MSI use standard memory DDR4 or the newest DDR5, and they are incompatible with each other physically and electrically. An error in choosing the memory type will result in the laptop simply not turning on or giving an error when trying to start.
It is important to pay attention to the frequency of operation of the modules. If your laptop supports 3200 MHz, then setting the bar to 2666 MHz will not give an increase in performance, and the memory is 3600 MHz may operate at reduced frequency or cause instability. It is best to select modules with identical characteristics to those already installed in the system, especially if you plan to work in dual-channel mode.

- 🚫 Do not mix modules from different manufacturers and different volumes unnecessarily
Pay special attention to the maximum capacity supported by the motherboard. Some older models have a limitation in 16 GB, even if the slots physically fit more. Trying to install a module on 32 GB into such a system will result in the system seeing only part of the memory or not booting at all.
⚠️ Attention: When purchasing DDR5 modules, make sure that your MSI processor and motherboard officially support this standard, since the physical key (notch) is different from DDR4 and it is impossible to insert such a module into the old slot.

Tools and workplace preparation
The success of the upgrade procedure depends 90% on proper preparation. You'll need a clean, well-lit area, preferably with a hard surface, to avoid damaging the laptop case during disassembly. The tool you will need is a Phillips head screwdriver that matches the screws on your device. MSI, usually the size is PH0 or PH1.
A critical element is protection against static electricity, which can instantly damage motherboard components. It is recommended to use an antistatic wrist strap connected to ground or regularly touch an unpainted metal part of the computer case or battery before each time you touch internal components.
- 🛠️ Phillips screwdriver (size depends on the model, most often PH0)
- 🧤 Antistatic wrist strap or hand grounding option
- 📦 Capacity for screws so as not to lose them during disassembly
- 🔦 Flashlight for illuminating hard-to-reach places inside the case
It is also worth preparing a plastic card or pick to carefully pry off the laptop lid. Metal tools can scratch the case or short out contacts if they accidentally hit the board. It is important to remove all external peripheral devices: mouse, flash drives, external hard drive to avoid accidental damage to the ports.
☑️ Preparing for memory replacement
Procedure for disassembling the case of an MSI laptop
The process of opening the case begins with completely disconnecting the laptop from the network and removing the battery, if it is removable. On most modern models of the series GS, GE or GL The battery is built-in, so it can only be accessed after removing the bottom cover. Never attempt to disconnect a live battery cable.
The screws on the bottom cover may be hidden by rubber feet or serial number stickers. Gently pry the legs with a plastic pick, without using excessive force so as not to break their fastenings. After removing all visible screws, the cover can be held on by latches that need to be carefully unfastened around the perimeter.
Some models MSI There are special service hatches that are closed with separate screws and allow you to access the memory slots without completely disassembling the case. If there is such a hatch, this will greatly simplify the task and reduce the downtime of the device. Check for the presence of such holes before starting complete disassembly.
⚠️ Attention: MSI models with backlit keyboards and complex cooling systems often use screws of different lengths. Be sure to note or photograph where each screw is attached so as not to damage the case during reassembly.
What to do if the lid does not budge?
If the cover does not budge, check to see if there are any screws remaining under the stickers or rubber feet. Sometimes the screws are hidden under warranty stickers, but removing them may not be desirable to preserve the warranty. In this case, it is better to contact a service center.
Replacing and installing memory modules
After removing the cover, the first thing you need to do is disconnect the battery cable from the motherboard. This is a mandatory step to prevent short circuits when working with memory modules. Carefully move the connector latch and remove the plug, trying to pull on the connector body and not on the cable itself.
To remove the old memory module, you need to slightly move the metal latches located on the sides of the slot to the sides. The bar itself will rise at an angle of approximately 30 degrees. It can then be easily removed by grasping the edges without touching the gold contacts and chips with your hands.
- 🔓 Move the clamps to the sides, the module will rise
- 👐 Grasp the bar only by the edges, avoid contact with the contacts
- ⚡ Insert the new strip at an angle, making sure the notch matches
- 🔒 Press the module until the latches click
When installing a new module SODIMM Make sure the notch on the pad aligns with the protrusion in the slot. Insert the bar at an angle, press it until the latches click. If the latches do not snap into place, do not force them; check that the module is oriented correctly.
If you install two memory modules, try to place them in slots of the same color to enable dual-channel mode, which significantly increases the speed of data exchange between the processor and memory.
Performance check and testing
After installing the modules and connecting the battery, do not rush to close the lid immediately. First, turn on your laptop and check if the system has detected the new amount of memory. Go to Task Manager (Ctrl+Shift+Esc) to the "Performance" -> "Memory" tab and make sure that the volume corresponds to the declared one.
If the system does not see memory or displays errors, try rearranging the modules into other slots or checking them individually. Sometimes the problem may be a bad connection or a defective module. It's also worth checking your settings BIOS/UEFI, where sometimes you need to manually enable the XMP/DOCP profile for the memory to operate at the stated frequency.
To reliably check the stability of operation, it is recommended to run a specialized test, for example, MemTest86 or the built-in Windows Memory Checker. This will reveal hidden errors that may appear later in the form of blue screens or program crashes.
| Memory type | Max. volume (example) | Frequency (standard) | Housing type |
|---|---|---|---|
| DDR4 SODIMM | 64 GB | 2666 - 3200 MHz | Regular laptop |
| DDR5 SODIMM | 64 GB | 4800 - 5600 MHz | New MSI models |
| LPDDR4x (soldered) | Cannot be replaced | 4266 MHz | Ultrabooks |
| DDR3L SODIMM | 16 GB | 1600 MHz | Old models |
⚠️ Attention: On MSI Prestige series ultrabooks or some Modern models, the memory is often soldered to the motherboard and cannot be replaced. In such cases, an upgrade is not possible, and you need to choose a model with the required amount of memory immediately upon purchase.
Correct orientation of the memory module and reliable contact of the latches are the key to stable operation of the laptop after the upgrade. Incomplete latching will lead to unstable operation and frequent reboots.
Common errors and ways to resolve them
One of the most common mistakes is installing memory with the wrong voltage. For example, DDR3L modules (low voltage 1.35V) may not work correctly in slots designed for standard voltage 1.5V, and vice versa. This may result in the laptop turning on but giving errors or freezing.
Another problem is mixing modules with different timing characteristics. If you add a module to an already installed one, but they have different delays (CL), the system will automatically adjust to the slowest module. This is not critical, but may not provide the expected performance increase.
- ⚠️ Do not use memory with non-standard voltage
- 🔄 When mixing modules, the system operates at the parameters of the slowest
- 🔋 Always disconnect the battery before working with the board
If after installing a new module the laptop does not turn on at all, check whether the battery cable came loose during assembly. It is also worth checking whether the screws have gotten inside the case and whether they have shorted the contacts. In rare cases, it may be necessary to reset the CMOS memory to correctly detect the new hardware.
How to reset BIOS settings?
To reset the BIOS, find a jumper on the motherboard labeled CLR_CMOS or a reset button. Close the jumper contacts for 5-10 seconds with the battery disconnected, or press the reset button. This will reset the settings to factory defaults and may help with problems detecting new memory.
FAQ: Answers to frequently asked questions
Is it possible to install memory with a higher frequency than the laptop supports?
Yes, you can install a higher frequency module, but it will operate at the maximum frequency supported by your processor's memory controller and motherboard. There will be no performance gain, but usually no problems arise, since the memory automatically reduces the frequency.
Do I need to reinstall Windows after replacing memory?
No, the Windows operating system automatically adapts to changes in memory size. Reinstallation is not required, except in rare cases when the system does not see the new volume and requires a reset through the BIOS.
How many memory slots do MSI laptops usually have?
Most MSI gaming and work laptops (GF, GE, GS, GP series) have two SODIMM slots. However, in some thin models (Prestige, Modern series), one or both modules can be soldered into the board, leaving only one free slot or no expansion options at all.
What to do if the laptop does not see the new memory module?
First, check that the module is inserted tightly and that the latches are latched. Try cleaning the module contacts with an eraser. If this does not help, check the functionality of the slot by installing the old module there. The module may be defective or the slot may be damaged.
Does replacing memory affect MSI's warranty?
According to the policy of most manufacturers, including MSI, replacing memory modules that are not soldered will not void the warranty on the remaining components of the laptop, unless mechanical damage was caused during installation. However, if you damage the case or board, the warranty will not cover that damage.
