Soldered RAM in a laptop: features, testing and alternatives

In modern laptops, manufacturers are increasingly abandoning traditional RAM slots in favor of soldered RAM chips. This solution makes it possible to make devices thinner, lighter and more energy efficient, but deprives users of the possibility of a simple upgrade. If you are faced with a laptop where the memory is “soldered” into the motherboard, you probably have questions: how does this affect performance, can it be replaced, and what to do if the volume is not enough?

In this article we will look at why manufacturers are switching to soldered RAM, how to determine its type in your laptop, which models are most often equipped with such memory (for example, MacBook Air M1, Dell XPS 13 or ASUS ZenBook), and also consider alternative ways to improve system performance. We will pay special attention critical nuances when trying to modify such memory - from the risk of damage to the board to loss of warranty.

What is soldered-in RAM and why is it used?

Soldered (or integrated) RAM - these are memory chips that are soldered directly to the laptop motherboard, rather than installed in removable slots SO-DIMM. This approach became popular with the spread of ultrabooks and processor-based devices. Apple Silicon (For example, M1/M2), as well as some lines Intel (series Core i3/i5/i7 11th and 12th generations with support LPDDR4X/LPDDR5).

The main reasons for switching to soldered memory:

• 📉 Compactness: the absence of slots allows you to reduce the thickness of the case to 10–15 mm (as in MacBook Air or HP Spectre x360).
• ⚡ Energy efficiency: integrated LPDDR-memory consumes 20–30% less energy than DDR4 SO-DIMM.
• 💨 Heat dissipation: Fewer components simplify cooling, which is critical for thin laptops.
• 🔧 Cheaper production: the absence of connectors reduces the cost of assembly (but not always the final price for the buyer).

However, this solution also has a downside: the user is deprived of the opportunity update or replace RAM without soldering equipment and specialized skills. Moreover, in 90% of cases, an attempt to resolder leads to loss of warranty and risk damaging your laptop.

How to find out if the memory is soldered into your laptop

Before planning an upgrade, it is necessary to accurately determine the type of installed RAM. Here are some reliable ways:

1. Via task manager (Windows)

Open Task Manager (keyboard shortcut Ctrl + Shift + Esc), go to the tab Performance → Memory. The memory type will be indicated in the upper right corner (for example, DDR4 or LPDDR4X) and the number of slots used. If only one slot is specified or there is no information about the slots, the memory is most likely soldered in.

2. Using the command line

Run Command line as administrator and enter:

wmic memorychip get devicelocator, capacity, memorytype

If the response is missing a field DeviceLocator (or indicated ChannelA-DIMM0 without the possibility of replacement), this is a sign of soldered memory. For macOS similar information can be obtained through System report → Memory.

3. Physical examination

The most reliable method is to disassemble the laptop and inspect the motherboard. Soldered memory looks like several small chips (usually 2-4 pieces) next to the processor, without connectors. For example, in Lenovo Yoga Slim 7 or Acer Swift 3 chips LPDDR4X located under the heat pipes.

An example of the appearance of soldered memory

In photographs of laptop motherboards with soldered-in RAM, the memory chips are usually labeled as “Samsung K4”, “SK Hynix H9”, “Micron MT” and have dimensions of 8x10 mm. They are soldered directly to the board without the possibility of mechanical removal.

If you are not confident in your abilities, it is better to use online databases, for example, Crucial System Scanner or NotebookCheck, where the characteristics of specific models are indicated.

Laptop models with soldered-in RAM: table

Below are popular series of laptops where memory is soldered into 90% of configurations. Please note that even within the same line there may be exceptions (for example, top versions Dell XPS 15 sometimes equipped with removable slots).

Brand	Series/Model	Memory type	Max. volume (GB)
Apple	MacBook Air (M1/M2), MacBook Pro 13" (M1/M2)	LPDDR5 (soldered in)	8–24
Dell	XPS 13 (9310, 9315), XPS 15 (9520)	LPDDR4X/LPDDR5	16–32
HP	Spectre x360 (13/14"), Envy 13	LPDDR4X	8–16
Lenovo	Yoga Slim 7, IdeaPad 5 Pro	LPDDR4X	16
ASUS	ZenBook 14 (UX425), Vivobook S14	LPDDR4X	8–16

Important: in some models (for example, Lenovo ThinkPad T14 or HP EliteBook 840) there may be a combined circuit - part of the memory is soldered, and part is installed in the slot SO-DIMM. Before purchasing, check the configuration on the manufacturer's website!

Is it possible to replace or increase soldered memory?

Technically You can replace the soldered RAM, but this comes with a number of difficulties:

⚠️ Attention: Resoldering memory chips requires professional equipment (thermal air soldering station, BGA trinkets) and experience in working with microelectronics. Wrong actions will lead to motherboard damage or peeling of tracks. In 80% of cases, a laptop loses its warranty after such a procedure.

Replacement algorithm (for specialists):

1. Remove the back cover and heat pipes.
2. Determine the model of memory chips (usually markings begin with K4, H9 or MT).
3. Select identical chips with the same capacity and type (LPDDR4X 4266 MHz etc.).
4. Carefully remove old chips using thermal air (temperature ~350°C).
5. Install new chips, checking pin alignment.
6. Flash the BIOS (sometimes required to recognize a new volume).

The cost of such a service in service centers starts from 15,000 rubles (excluding the cost of chips), and the result is not guaranteed. For example, in MacBook Pro M1 memory is soldered to the processor (unified memory), and replacing it is physically impossible without replacing the entire chip Apple Silicon.

Alternative Ways to Improve Performance

If replacing memory is not possible or practical, consider the following optimization options:

• 🖥️ Using the swap file: Increase virtual memory in Windows settings (Control Panel → System → Advanced system settings → Performance → Settings → Advanced → Virtual memory). The optimal size is 1.5–2× the amount of RAM.
• 🗄️ Drive update: Replacement HDD on SSD NVMe (For example, Samsung 980 Pro or WD Black SN850X) gives a performance boost of up to 300% in everyday tasks.
• 🧹 Cleaning startup: Disable unnecessary programs via Task Manager → Startup. This will free up to 1–2 GB of RAM at system startup.
• ☁️ Cloud solutions: Services like Google Drive for Desktop or OneDrive Files On-Demand allow you to work with files without completely loading them into memory.

For creative tasks (video editing, 3D modeling), consider renting cloud workstations (Amazon WorkSpaces, Shadow PC) or using external GPUs (eGPU), which will reduce the load on the built-in memory.

Risks and pitfalls of soldered memory

In addition to the impossibility of upgrading, soldered RAM poses other dangers:

⚠️ Attention: In laptops with Apple M1/M2 and some Intel Evo-devices memory is divided between the CPU and GPU. If even one chip fails LPDDR5 The entire motherboard may need to be replaced, which is comparable in cost to buying a new laptop.

Main risks:

• 🔥 Overheating: Soldered chips are often located under the processor and are dependent on the overall system for cooling. Under intense loads (rendering, gaming), the temperature may exceed 90°C, which shortens the service life.
• 🛠️ Difficulty of repair: Even in service centers, not everyone undertakes to resolder the memory due to the high risk of damage to the board. For example, in MacBook Air M1 memory chips are soldered to the processor, and replacing them requires replacing the entire chip Apple Silicon.
• 💸 Obsolescence: After 3-4 years, the memory capacity may become insufficient for new programs (for example, Photoshop 2023 recommends 16 GB of RAM), and it will not be possible to upgrade it.

When purchasing a laptop with soldered-in memory, reserve capacity for 3–5 years in advance. For example, if 8 GB is enough for you today, choose a configuration with 16 GB.

FAQ: Frequently asked questions about soldered RAM

Is it possible to add memory to a laptop if it is soldered?

No, it is physically impossible to add memory. The only option is to replace the existing chips with larger ones (for example, from 8 GB to 16 GB), but this is a complex and expensive procedure, available only in specialized services. In most cases, it is cheaper to sell the laptop and buy a new one with the required amount of RAM.

What is the minimum amount of soldered memory worth choosing in 2026?

For office tasks (working with documents, browsing) 8 GB is enough, but for multitasking (10+ browser tabs + instant messengers + light programs) 16 GB is better. For creative tasks (video editing, 3D) or games - at least 32 GB. Remember that soldered-in memory cannot be expanded!

Is it true that soldered memory works faster than removable memory?

Yes, due to shorter traces on the motherboard and the use of modern standards (LPDDR5 against DDR4) soldered-in memory can have lower latency (latency) and higher bandwidth. For example, in MacBook Pro M1 Memory bandwidth reaches 68 GB/s, which is 2–3 times higher than removable modules DDR4-3200.

Can I use external RAM (e.g. via USB)?

There is no full-fledged “external RAM”, but there are solutions like USB-RAM (For example, Samsung T7 Shield with function ReadyBoost on Windows). They speed up cache work, but do not replace physical memory. For a noticeable effect, you need a drive with high read/write speeds (from 1000 MB/s).

What other laptops are produced with removable memory?

Removable slots SO-DIMM saved in gaming laptops (ASUS ROG Strix, MSI GE76), workstations (Dell Precision, HP ZBook) and some business lines (Lenovo ThinkPad P-series, Acer TravelMate P6). Also, removable memory is often installed in budget models (for example, Acer Aspire 5 or Lenovo IdeaPad 3).
