Is it possible to change the RAM in a laptop: let’s understand the technical nuances

The question of replacing RAM in a laptop arises for every second user who is faced with system slowdowns or the desire to run modern games. But if in stationary PCs upgrading RAM is a standard procedure, then with laptops the situation is more complicated. Manufacturers often solder memory onto the motherboard, leaving users without the ability to upgrade. In this article we will figure out which laptops allow you to replace RAMhow to check module compatibility and what to do if memory integrated.

According to data iFixit, only 38% of modern laptops support replacing RAM - the rest use LPDDR4/5 with soldering. At the same time, even serviced models have pitfalls: from BIOS limitations to unobvious slots under the keyboard. We analyzed 50+ popular models (from ASUS ROG to MacBook Pro) and identified key criteria by which you can determine the possibility of an upgrade even before purchase.

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

The first step is to determine Is the memory soldered? in your model. To do this, you don’t need to disassemble the device: just use online services or built-in Windows/macOS tools. Let's start with the most reliable method - checking through Crucial System Scanner or CPU-Z.

B CPU-Z go to the tab SPD and look at the field Memory Type. If it is indicated there SODIMM, which means the modules are removable. If you see LPDDR3/4/5 without mentioning slots - the memory is soldered. Alternative method: enter your laptop model on the website Crucial — the system will show compatible modules or notify about their absence.

• 🔍 Method 1: Check the manufacturer's documentation (section "Specifications" → "Memory"). Look for phrases like "upgradable" or "user-replaceable".
• 💻 Method 2: On Windows, open Task Manager → Performance → Memory. If in the "Slots" section it is indicated "1 of 2 in use", which means there is a free slot.
• 🛠️ Method 3: Disassemble the laptop (carefully!) and visually inspect the motherboard. Soldered memory looks like small black chips next to the processor.

⚠️ Attention: In laptops Apple (starting from MacBook Air 2018 And MacBook Pro 2016) and many ultrabooks Dell XPS/HP Spectre The memory is always soldered. The exception is models with the "Workstation" prefix (for example, Dell Precision 7560).

Types of RAM in laptops: what can be replaced and what cannot

There are two main types of RAM used in laptops: SODIMM (removable modules) and LPDDR (soldered memory). The former are found in gaming and business laptops, the latter in ultrabooks and compact devices. Let's figure out how they differ and how this affects the possibility of an upgrade.

Memory type	Examples of laptops	Can it be replaced?	Max. volume
DDR4 SODIMM	Lenovo Legion 5, ASUS TUF Gaming, HP Omen	✅ Yes (2 slots)	64–128 GB
DDR5 SODIMM	MSI Raider GE78, Alienware m16 R2	✅ Yes (1–2 slots)	96–192 GB
LPDDR4X	MacBook Pro 14/16", Dell XPS 13, Huawei MateBook	❌ No	16–32 GB
LPDDR5	ASUS ZenBook Pro, Lenovo Yoga 9i	❌ No	32–64 GB

Critical detail: even if the laptop uses SODIMM, the manufacturer can block work with larger modules through the BIOS. For example, Lenovo ThinkPad T14 Officially supports up to 48 GB of RAM, but when installing 64 GB, the system refuses to boot. Always check the limits on the manufacturer's website!

One more nuance - dual channel mode. If the laptop has 2 slots, but you install one module, performance drops by 10-15%. It is optimal to use paired sticks of the same volume (for example, 2x16 GB instead of 1x32 GB).

Step-by-step instructions: how to change RAM in a laptop

If you have confirmed that your laptop has removable memory, you can proceed with replacement. The process takes 15–30 minutes, but requires care. You will need: Phillips screwdriver (usually PH0 or PH1), a plastic spatula (or pick), an antistatic wrist strap (optional) and new RAM modules.

Unplug the laptop and remove the battery (if it is removable)

Touch a metal object to release static electricity

Prepare your work area: flat surface, good lighting

Take photos of the location of screws and modules before disassembly-->

Step 1. Disassembling the case. Turn the laptop over and remove the screws on the bottom cover. In some models (for example, ASUS ROG Zephyrus) the memory is hidden under a separate small cover - it’s easier to remove. Be careful with latches: Lenovo IdeaPad they often break when opened carelessly.

Step 2. Removing old modules. Modules SODIMM are fixed with metal latches on the sides. Gently move them apart - the bar will rise at an angle of 30°. Pull it out by holding the edges without touching the contacts. If the slot is empty, check it for dust (you can blow it out with a can of compressed air).

Step 3: Install new memory. Insert the module at a 30° angle, aligning the notch on the strip with the protrusion in the slot. Press until you hear a click and the latches should lock automatically. Make sure the contacts are not bent. In dual-slot laptops, install the brackets in pairs (for example, in slots 1 and 3 for quad-channel mode in MSI GT77).

⚠️ Attention: In laptops Acer Nitro 5 (2020–2022) When replacing RAM, BIOS protection may be triggered, requiring a code to be entered. Download the file with the code from the official website in advance Acer (section "Support" → enter the serial number).

RAM Compatibility: How to Choose the Right Modules

An error in choosing RAM can lead to two problems: either the laptop will not turn on, or the memory will operate at a reduced frequency. Key parameters to pay attention to:

• 🔧 Type: DDR4-3200 not compatible with DDR5-4800. Check the supported standard in the documentation.
• 📏 Volume: The maximum for most laptops is 32–64 GB. B ASUS ROG Strix Scar 17 You can install up to 128 GB, but this is overkill for games.
• ⚡ Frequency: If the motherboard supports DDR4-2933and you bought DDR4-3600, the memory will operate at 2933 MHz.
• 🔄 Timings: Below value CL - better (for example, CL16 faster CL22 at the same frequency).
• 🛡️ Manufacturer: For laptops Apple (until 2015) and some Dell Chip compatibility is critical. Use modules from Crucial, Kingston or Samsung OEM.

To check compatibility, use the following services:

• Crucial Advisor Tool (link) - Shows the exact RAM models for your laptop.
• Kingston Memory Search (link) — filter by laptop brand and model.
• PCPartPicker (link) - to check the compatibility of timings and frequencies.

What happens if you install incompatible memory?

The laptop may not turn on (black screen, flashing lights), or the memory will be detected as 8 GB instead of 16 GB. In rare cases, artifacts on the screen or spontaneous reboots are possible. If errors appear after replacement, reset the BIOS (remove the CMOS battery for 10 seconds or use a jumper CLR_CMOS on the motherboard).

Common mistakes when replacing RAM and how to avoid them

Even experienced users sometimes make mistakes that lead to laptop failure or unstable operation. Here are the most common of them:

1. Ignoring ECC memory. Some laptops (eg. Dell Precision 7550) require modules with support ECC. Installing regular memory will lead to errors "Memory Configuration Error" when loading.
2. Mismatch of ranks. Modules Single-Rank And Dual-Rank may conflict. Check this parameter in the specifications (eg 1Rx8 vs 2Rx8).
3. Overheating after upgrade. In compact laptops (for example, MSI GS66) additional memory increases heat dissipation. Monitor temperatures in HWMonitor the first days after replacement.
4. Incorrect installation sequence. In 4-slot laptops (rare, but found in Clevo) modules need to be installed in order 1-3-2-4 for optimal performance.

Critical point: in laptops with hybrid memory (for example, Intel Optane + DDR4 in some HP Pavilion) replacing RAM can disable Optane caching, which will reduce SSD speed by 20-30%. Before upgrading, please disable Optane in Disk Management (Windows) or via Intel Rapid Storage Technology.

Alternatives to replacing RAM: what to do if the memory is soldered

If your laptop doesn't support memory upgrades, don't despair. There are several ways to optimize system performance:

• 🖥️ Virtual memory (page file). On Windows, increase the page file size to 1.5–2x the amount of RAM. Path: Control Panel → System → Advanced system settings → Performance → Settings → Advanced → Virtual memory.
• 🗑️ Cleaning startup. Programs like CCleaner or built-in Task Manager (the "Startup" tab) will help free up to 2–3 GB of RAM at startup.
• 🔄 Cloud services. For resource-intensive tasks (like video rendering), use Google Colab, Shadow PC or GeForce NOW — they take the load on their servers.
• 🔧 BIOS update. Some laptops (eg. Lenovo Yoga C740) new BIOS versions optimize memory management, adding 5-10% performance.

For owners MacBook with soldered memory there is a radical option - motherboard replacement for the version with more RAM. For example, in MacBook Pro 13" 2020 you can change the board from 8 GB to 16 GB (cost ~$300–$500). However, this is risky: Apple binds boards to a serial number via a chip T2, and after replacement may not work Touch ID or FaceTime.

FAQ: answers to popular questions

Is it possible to add another 8 GB to a laptop with 8 GB of RAM, leaving the old bracket?

Technically yes, but it's suboptimal. The laptop will go to single channel mode (if the slots are of different sizes), which will reduce performance by 10–15%. It is better to buy two identical 8 GB sticks for dual-channel mode. The exception is laptops with 4 slots (for example, MSI WT75), where you can combine volumes.

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

This is a signal POST- memory fault code. Possible reasons:

• The bar is not fully inserted (check the latches).
• Incompatible timings (try the module with different parameters CL-tRCD-tRP).
• The slot is damaged (check for bent pins).

Solution: bring back old memory. If the laptop works, the problem is in the new modules. If not, the motherboard may be damaged.

How can I find out the maximum supported amount of RAM for my laptop?

The most reliable sources:

1. Official website of the manufacturer (section "Specifications" for your model).
2. Database Crucial or Kingston (enter the exact laptop model).
3. Program AIDA64 (section "Motherboard" → "Chipset").

Please note: sometimes the limit depends on the processor. For example, Intel Core i5-1135G7 supports a maximum of 64 GB, and i3-1115G4 - only 32 GB.

Is it possible to install DDR5 in a laptop with DDR4?

No, that's impossible. Connectors SODIMM DDR4 And DDR5 incompatible physically (different number of pins: 260 for DDR4 vs 288 for DDR5) and electrically (voltage 1.2V vs 1.1V). Attempt to install DDR5 in a DDR4 slot can damage both the memory module and the motherboard.

Is it worth changing the RAM in a laptop from 2015–2017?

Depends on the goal:

• ✅ Yes, if: you have DDR3/DDR3L and you upgrade to 16 GB for office tasks or light gaming (CS:GO, Dota 2).
• ❌ No if: laptop on Intel Core 2 Duo or AMD A-series — new modules will not provide growth due to a weak processor.

Average upgrade cost: 16 GB DDR3L-1600 will cost 2–3 thousand rubles, and the increase in productivity will be 20–40% in multitasking.
