Is it possible to increase RAM on a laptop: a complete guide 2026

Question about increasing RAM (RAM) on a laptop occurs for many users when the device begins to “slow down” when multitasking or working with resource-intensive programs. But not every laptop allows an upgrade: manufacturers often solder memory to the motherboard or limit the maximum volume. In this article we will figure out is it possible to add RAM for your model, how to check compatibility and what to do if the upgrade is not possible.

Let us warn you right away: even if it is technically possible to increase memory, it is not always advisable. For example, in ultrabooks type MacBook Air or Dell XPS 13 The RAM is soldered, and in gaming laptops (ASUS ROG Strix, MSI Raider) there may be a free slot, but with strict frequency restrictions. We will help you avoid mistakes when choosing modules and tell you how not to turn an upgrade into a waste of money.

1. How to tell if you can increase the RAM on your laptop

The first step is to determine whether your model supports replacing or adding RAM. This depends on three factors:

• 🔧 Laptop design: Is there a physical RAM slot or is the memory soldered to the motherboard.
• 📋 Maximum supported volume: Even if there is a slot, the motherboard and processor may not be able to handle more than 16–32 GB.
• 🔄 Memory type: DDR3, DDR4 or DDR5 — you can’t mix them.

The most reliable way to check is to look into documentation to a laptop (on the manufacturer's website) or use programs like CPU-Z, AIDA64. For example, in CPU-Z on the tab SPD Memory slots and their occupancy are displayed. If there is only one slot (Slot #1), and the second one is missing - the memory is soldered.

Also note models with hybrid memory (For example, Intel Optane + DDR4 in some Lenovo ThinkPad). Here an upgrade is possible, but requires precise selection of modules. If in doubt, check user reports on forums (for example, NotebookCheck or Reddit), where they often share their experience of upgrading specific models.

2. Types of RAM: what can be installed and what cannot

RAM for laptops comes in two form factors: SO-DIMM (removable modules) and soldered (built into the board). The first allows an upgrade, the second does not. But even if you SO-DIMM, you need to consider:

Parameter	DDR3	DDR4	DDR5
Years of manufacture	2007–2015	2015–2021	2021–present time
Frequency (MHz)	800–2133	1600–3200	3200–6400
Voltage (V)	1.35–1.5	1.2	1.1
Compatibility	Old laptops (before 2016)	Most modern	Flagships 2022+ (for example, ASUS ZenBook Pro)

Critical error: you cannot mix memory of different generations (for example, DDR3 and DDR4) or install modules with different frequencies - this will lead to a drop in performance or boot failure. It is also important to consider memory rank (Single Rank vs. Dual Rank). For example, two modules Single Rank 8 GB can work faster than one Dual Rank 16 GB, due to the characteristics of the memory controller in the processor.

If your laptop supports DDR5, pay attention to PMIC (Power Management IC) - on some models (Lenovo Yoga 7, HP Spectre x360) it may not cope with high-voltage modules, which will lead to overheating. For DDR4 there is an urgent problem with XMP profiles: Not all laptops support them, so the memory will run at the standard frequency (for example, 2400 MHz instead of 3200 MHz).

3. How to check the maximum amount of RAM for your laptop

Manufacturers often underestimate official data on the maximum memory capacity. For example, Dell Latitude E7470 According to the documentation, it supports up to 16 GB, but users successfully install 32 GB. To find out the real limit:

1. Check the processor specifications on the website Intel ARK or AMD. For example, Intel Core i7-10750H Officially supports up to 128GB DDR4-2933, but the laptop may limit this value.
2. Use the utility Thaiphoon Burner to read SPD memory chips - it will show which modules are installed and what parameters the controller supports.
3. Read reviews on Amazon or AliExpress for your model - there are often photos with 32/64 GB installed.

Pay special attention to laptops with AMD Ryzen 4000/5000 processors (For example, Lenovo Legion 5 or ASUS TUF Gaming). Their memory controller often allows you to use more capacity than stated by the manufacturer. For example, Ryzen 7 5800H theoretically supports up to 128 GB DDR4-3200, but the laptop may have a limitation at the BIOS level.

Don't forget about operating system bit depth:

• 🖥️ Windows 10/11 32-bit - maximum 4 GB (even if 16 GB is physically installed).
• 🖥️ Windows 10/11 64-bit - up to 128 GB (Home) or 2 TB (Pro/Enterprise).
• 🐧 Linux — limits depend on the kernel (usually up to 64 TB).

4. Step-by-step instructions: how to increase RAM on a laptop

If you are convinced that an upgrade is possible, follow this algorithm. Important: before starting work turn off the laptop, disconnect the battery (if removable) and ground yourself to avoid static discharge.

Unplug the laptop and remove the battery|

Prepare a screwdriver (usually Phillips or Torx T5)|

Buy compatible memory modules (preferably included)|

Back up important data|

Prepare an antistatic wrist strap or touch the metal case of the system unit-->

Step 1: Accessing RAM Slots

In most laptops, the memory is located under the bottom cover (for example, HP Pavilion, Acer Aspire). On some models (Lenovo ThinkPad T-series) To access the RAM you need to remove the keyboard. Find disassembly instructions at YouTube by searching for “[laptop model] RAM upgrade”.

Step 2. Installing new modules

Modules SO-DIMM are installed at an angle of 45° and secured with latches. If there is only one slot, and you are adding a second module, place it in Slot 0 (usually it is closer to the processor). After installation, turn on the laptop and check memory recognition in BIOS (section System Information or Memory).

Step 3: Check stability

Use tests:

• 🛠️ MemTest86 (runs from a flash drive, tests for 4+ hours).
• 🖥️ Windows Memory Diagnostic (built into the system, launch via mdsched.exe).
• 🎮 Prime95 (memory load in mode Blend).

If errors appear, try swapping modules or updating the BIOS.

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

1. Check whether the modules are inserted correctly (the latches should click).

2. Try to leave only one module (test each one in turn).

3. Reset BIOS (remove CMOS battery for 10 minutes or use jumper CLR_CMOS).

4. If the laptop turns on but does not see the memory, update the BIOS to the latest version.

5. Top 5 mistakes when increasing RAM and how to avoid them

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

⚠️ Attention: If you bought memory with a frequency higher than the processor supports (for example, DDR4-3600 for i5-8250U, which “pulls” only DDR4-2400), the modules will operate at a reduced frequency, but this may cause the memory controller to overheat.

Mistake 1. Buying incompatible modules

For example, for Lenovo ThinkPad T480 need memory DDR4-2400 SO-DIMM with support ECC (if processor Intel Xeon). If you install the normal DDR4-2666, the laptop will either not start or will constantly reboot. Always check part number original memory (can be found on the module sticker or in CPU-Z).

Error 2: Ignoring dual-channel mode

Two identical modules (for example, 2x8 GB) are 10-15% faster than one 16 GB. But if you add modules of different sizes (8 GB + 16 GB), dual-channel mode won't turn on. Some laptops (eg. ASUS ROG Zephyrus) this can lead to a 20-30% drop in FPS in games.

Error 3. Neglecting to update the BIOS

Older BIOS versions may not support new memory modules. For example, in Dell XPS 15 9570 not recognized with BIOS version 1.4.0 DDR4-3200, although the processor (i7-8750H) supports it. Updating to version 1.12.0 solves the problem.

Error 4. Installing memory with an XMP profile without support

Many modules (eg Corsair Vengeance or Kingston HyperX) are sold with XMP profiles for overclocking. But 90% of laptops do not support memory overclocking through BIOS. As a result, the modules will operate at a standard frequency, and you will be wasting the overpayment for “game” memory.

Error 5: Using high voltage memory

Some modules DDR4 require 1.35 V instead of the standard 1.2 V. This can lead to overheating of the memory controller in processors Intel 8th–11th generations (For example, i7-10750H). Check the voltage in the module specifications!

6. Alternatives to upgrading RAM: what to do if you can’t increase memory

If your laptop does not support memory replacement (for example, Apple MacBook Pro M1 or HP Envy x360 with soldered LPDDR4X), consider these options:

• 🖥️ OS optimization: disable unnecessary programs in startup (Task Manager → Startup), use ReadyBoost (for HDD) or Windows SuperFetch (for SSD).
• 💾 Swap on SSD: move the swap file (pagefile.sys) to fast NVMe drive. B Windows 11 this gives an increase of up to 20% in multitasking.
• ☁️ Cloud storage: services like Shadow PC or GeForce NOW allow you to “rent” a virtual PC with 16–32 GB of RAM for resource-intensive tasks.
• 🔄 Upgrade to a more powerful model: If the laptop is older than 5 years, it is sometimes cheaper to buy a new machine (eg. Lenovo ThinkPad P1 with 64 GB DDR5) than trying to modernize the old one.

For owners MacBook with chips Apple Silicon (M1/M2) there is good news: thanks unified memory (RAM + VRAM) even 8 GB works more efficiently than 16 GB in Intel-macah. But if you are working with Final Cut Pro or Adobe Premiere, it is better to choose a model with 16 GB at the purchase stage - an upgrade will not be possible later.

7. Is it worth increasing RAM in 2026: feasibility analysis

RAM prices fluctuate greatly. For example, in 2022 32 GB DDR4-3200 cost ~$150, and in 2026 - already ~$80. But before buying, answer these questions:

• ❓ Why do you need more memory? For games (Cyberpunk 2077, Star Citizen) 16 GB is enough for rendering (Blender, After Effects) need 32+ GB.
• ❓ How long will the laptop last after the upgrade? If it is more than 5 years old, it may be better to invest in a new car.
• ❓ Does your processor support more capacity? For example, Intel Core i3-1115G4 Officially it can only handle 64 GB, but in practice it may not work stably with 32 GB.

According to tests TechSpot (2023), the performance gain when increasing RAM from 8 to 16 GB in games is ~5–10%, and from 16 to 32 GB – only 1–3%. But in professional tasks (for example, working with Photoshop and 50+ tabs Chrome) the difference reaches 40%. Therefore, the upgrade is justified only for specific scenarios.

If you decide to increase memory, buy modules with lifetime warranty (For example, Crucial or Samsung OEM). Avoid no-name brands - they often have problems with timings (latencies CL16 vs. CL19), which leads to lags.

FAQ: Frequently asked questions about increasing RAM on a laptop

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

No, this is physically impossible. SO-DIMM (for laptops) and DIMM (for PC) have different sizes and number of pins (260 vs. 288 for DDR4). In addition, laptops do not support a voltage of 1.35 V, which is typical for some DIMM-modules.

❓ Which is better: one 32 GB module or two 16 GB modules?

Two 16 GB modules are preferable as they work in two-channel mode, doubling memory bandwidth. One 32 GB module will work slower, although it will provide more capacity. The exception is laptops with 4 slots (rare), where you can install 4x8 GB for quad-channel mode.

❓ Why did the laptop start to slow down after upgrading the RAM?

Possible reasons:

• Incompatible timings (eg CL19 instead of CL16).
• Mixing modules from different manufacturers (even if they are of the same frequency).
• Old BIOS version that does not support new modules.
• Overheating of the memory controller (relevant for AMD Ryzen 4000 when using DDR4-3600+).

Solution: Get the old memory back and update the BIOS, then try installing the new modules one at a time.

❓ Is it possible to increase RAM on a laptop with soldered memory?

No, if the memory is soldered (LPDDR4/LPDDR5), it cannot be replaced or added. The only way out is to use external GPU (For example, Razer Core) with your own memory or switch to cloud solutions (Shadow PC). In some cases, OS optimization helps (disabling visual effects, using Linux with zram).

❓ Which memory brand is better to choose for an upgrade?

Recommended brands (based on reliability and compatibility):

• 🥇 Samsung OEM - original memory for many laptops (for example, Dell, HP).
• 🥈 Crucial — optimal price/quality ratio, lifetime warranty.
• 🥉 Kingston Fury - a good choice for gaming laptops (supports XMP).
• ⚠️ Avoid: Silicon Power, TeamGroup Vulcan (common compatibility issues).

For Apple MacBook (until 2020) suitable only Samsung or Hynix — other brands may not be recognized.
