Is it possible to replace soldered RAM in a laptop: myths and reality

Question about replacing soldered RAM (RAM) in a laptop occurs among users whose devices begin to “slow down” when working with modern applications. Manufacturers are increasingly soldering modules RAM to the motherboard, saving space and simplifying the design, but depriving users of the ability to upgrade. So is it possible to get around this limitation?

The answer is not as clear-cut as it seems. On the one hand, It is technically possible to resolder memory chips on some models, but this requires professional equipment and microelectronics skills. On the other hand, even a successful replacement does not always provide a performance increase due to limitations of the memory controller or BIOS. In this article we will look at when to replace a soldered RAM makes sense and when is the best time to consider alternatives.

What is soldered RAM and why is it soldered?

Unsoldered RAM (or soldered RAM) are memory chips that are directly soldered to the laptop motherboard, rather than installed in removable slots SO-DIMM. This approach allows:

• 📏 Reduce the thickness of the device (critical for ultrabooks and transformers);
• 💰 Reduce cost due to the lack of connectors and fastenings;
• 🔋 Increase energy efficiency (less contacts = less losses).

Manufacturers such as Apple (series MacBook Air/Pro since 2016), Dell (XPS 13/15), HP (Spectre, Envy) and Lenovo (Yoga, ThinkPad X1 Carbon), actively switching to soldered memory. For example, in MacBook Pro M1/M2 RAM integrated into the chip Apple Silicon, which makes replacing it impossible without replacing the entire processor.

However, not all laptops are slotless. Even in 2026, some models (e.g. Lenovo Legion or ASUS ROG Strix) maintain a hybrid architecture: part of the memory is soldered, and part is in slots. This is a trade-off between performance and maintainability.

Is it possible to physically replace soldered RAM: technical nuances

Theoretically yes, but in practice this is a task for specialized service centers. The process includes:

1. Diagnostics — determination of the type of memory chips (for example, LPDDR4X or LPDDR5) and their location on the board;
2. Dismantling — careful removal of old chips using BGA stations (temperature ~200–250°C);
3. Installation of new chips - soldering with precise adherence to the distances between contacts (step 0.4–0.65 mm);
4. BIOS firmware — sometimes a microcode update is required to recognize a new amount of memory.

Main risks:

• ⚡ Damage to the motherboard due to overheating;
• 🔌 Incompatibility of new chips with the memory controller;
• 💸 The cost of work (from 10,000 ₽) often exceeds the price of a new laptop.

What is a BGA station?

This is a professional chip soldering equipment that allows you to accurately control temperature and pressure. In domestic conditions, it is impossible to replace it with an iron or hair dryer - this is guaranteed to damage the board.

Another problem - BIOS restrictions. For example, in laptops HP EliteBook or Dell Latitude even after a successful resoldering, the system may not “see” the new amount of memory due to the rigid settings of the controller.

Which laptops allow you to replace soldered RAM: exceptions to the rules

Despite the trend towards non-removable memory, some models allow upgrades. Here are key examples:

Brand and model	Memory type	Max. volume after upgrade	Notes
Lenovo ThinkPad T14/P14s (2020–2022)	Hybrid (8 GB soldered + slot)	40 GB (8+32)	Requires BIOS update to support 32GB in slot
Dell XPS 15 9500/9510	Unsoldered LPDDR4X	64 GB (soldering only)	There are successful cases, but the guarantee is removed
Apple MacBook Pro 16" (2019, Intel)	Removable modules DDR4	128 GB	Latest MacBooks with replaceable RAM
Framework Laptop (2021–2023)	Removable modules DDR4	64 GB	Modular architecture, officially upgradeable

Laptops with processors stand apart Intel 12th–13th generation (For example, MSI Prestige 14 or Gigabyte Aero). They are sometimes used memory in LPCAMM format - a new standard that combines the compactness of soldered chips with the possibility of replacement (modules are attached to the board without soldering, but require special tools).

Alternatives to replacing soldered RAM: what to do if an upgrade is not possible

If replacement is not technically feasible or too risky, consider these options:

• 🔄 System optimization:
  • Disable unnecessary background processes in Task Manager;
  • Use lightweight Linux distributions (for example, Xubuntu or Linux Mint);
  • Increase the page file size (pagefile.sys) up to 1.5–2× of RAM volume.
• 🖥️ External graphics:
  • Connect eGPU (For example, Razer Core X) for resource-intensive tasks;
  • Use cloud services (Shadow PC, GeForce NOW) for games.
• 💾 Upgrade SSD:
  • Replacement HDD on NVMe (For example, Samsung 980 Pro) gives an increase in download speed;
  • Set up ReadyBoost (for Windows) using a fast flash drive.

For creative tasks (video editing, 3D modeling), it is sometimes more effective to rent capacity in the cloud. Services like Amazon EC2 or Google Cloud offer virtual machines with 64+ GB RAM at an hourly rate.

Step-by-step instructions: how to prepare to replace soldered RAM

If you decide to upgrade, follow this algorithm:

Back up your data (to an external drive or to the cloud)|

Check the memory chip model via AIDA64 or CPU-Z|

Buy compatible chips (eg Samsung K4U6E3S4AA-MGCL for LPDDR4X)|

Find a service with micro-soldering equipment (ask about experience with your laptop model)|

Prepare for loss of warranty (if it is still valid) -->

Important nuance: before soldering it is necessary reflash BIOS to a version that supports the new memory size. For example, for Lenovo ThinkPad T480s BIOS version required 1.40+so that the system sees 32 GB instead of the standard 16 GB.

The cost of work varies:

• 🔧Chip replacement LPDDR4X (16→32 GB) - from 12,000 ₽;
• 🔧 Replacement with LPDDR5 (32→64 GB) - from 20,000 ₽;
• 🔧 Diagnostics + BIOS firmware — 3,000–5,000 ₽.

Risks and pitfalls: what to expect after replacement

Even successful replacement of a soldered RAM does not guarantee perfect performance. Frequent problems:

⚠️ Attention: After resoldering memory chips in laptops Dell XPS 13 9360/9380 users encounter errors Memory Management (blue screen) due to incompatible timings of new modules. The solution is to manually configure the settings in the BIOS (if available).

Other possible consequences:

• 🔥 Overheating - new chips may have different heat dissipation;
• 🕒 Reduced battery life (by 10–15%) due to changed energy consumption;
• 🚫 Refusal of warranty service (even if the problem is not related to RAM).

Case study: after upgrade HP Spectre x360 from 16 to 32 GB users noted throttling (automatic reduction of processor frequency) due to exceeding TDP limits. In some cases the update helped ThrottleStop or rolling back chipset drivers.

When replacing soldered RAM definitely doesn't make sense

There are situations when an upgrade is not justified either technically or economically:

• 🍎 Laptops on Apple M1/M2/M3 — the memory is integrated into the processor, replacement is impossible;
• 💻 Ultrabooks with Intel Core i3/i5 U-series (For example, Acer Swift 3) - the memory controller limits the maximum to 16 GB;
• 🕒 Laptops over 5 years old - the cost of work will exceed the market price of the device;
• 🔋 Devices with a damaged board (for example, after liquid contact).

An alternative is to sell your old laptop and buy a new one with the required capacity. RAM. For example, instead of upgrading MacBook Air M1 (max. 16 GB) it is more advisable to consider MacBook Pro M3 with 32 GB.

⚠️ Attention: In laptops with AMD Ryzen 5000/6000 (For example, ASUS Zephyrus G14) soldered memory often operates in dual-channel mode. Replacing with modules with different timings can lead to a performance drop of 20–30%.

FAQ: Frequently asked questions about replacing soldered RAM

Is it possible to replace soldered RAM in MacBook Pro M1?

No. In chips Apple Silicon (M1, M2, M3) memory is integrated into the processor at the chip level. It is impossible to physically separate it without destroying the entire chip. The only way to increase the volume is to buy a model with the required quantity RAM initially.

How much does it cost to replace soldered RAM in a service?

The price depends on the laptop model and memory type:

• LPDDR4X (16→32 GB) - 10,000–15,000 ₽;
• LPDDR5 (32→64 GB) - 18,000–25,000 ₽;
• Additionally, BIOS firmware may be required (RUB 2,000–5,000).

For comparison: a new laptop with 32 GB of RAM costs from 80,000 rubles.

Is it possible to resolder memory chips yourself?

Theoretically yes, but in practice it requires:

• Experience with BGA station and a soldering hair dryer;
• Precise memory chips (eg. Micron MT62F2G32D8DS-035);
• Tools for removing BGA chips (stencil, flux, thermal paste);
• Tester for checking power circuits after soldering.

Without skills, the risk of damage to the board exceeds 90%. It is better to contact the service with positive reviews of such work.

How can I check if the memory in my laptop is soldered?

Methods:

1. Run CPU-Z → tab SPD. If there are no slots, the memory is soldered;
2. View a disassembly of your model at YouTube or iFixit;
3. Use the command in PowerShell:

   Get-CimInstance -ClassName Win32_PhysicalMemory | Select BankLabel, Capacity

   Lack of banks (BankLabel) indicates soldered memory.

Does replacing soldered RAM give a noticeable performance boost?

Depends on the task:

• 📈 Yes - for video editing (Adobe Premiere), 3D rendering (Blender), virtual machines;
• ➖ Minimum — for office programs, watching videos, light games;
• ⚠️ May worsen - if new chips have higher timings (CL22 instead of CL18).

For example, in tests PassMark replacing 16 GB with 32 GB gives an increase of only ~5–7% in synthetic tests, but up to 40% in real scenarios (for example, working with large tables in Excel).
