Quick Answer
No, you cannot upgrade soldered RAM. Soldered RAM is permanently welded to the motherboard during manufacturing and cannot be removed or replaced. If your laptop has soldered RAM and you need more, your only option is to buy a new laptop or live with what you have. Check before buying: look for keywords like “not upgradeable” or “soldered memory” in spec sheets, or use our laptop checker tool to verify if your model supports RAM upgrades.
What Is Soldered RAM?
Soldered RAM is computer memory that is permanently attached to the laptop’s motherboard using solder (melted metal). Unlike traditional SODIMM RAM modules (which plug into slots like USB sticks), soldered RAM is:
- Permanently fused to the motherboard via high-heat soldering during manufacturing
- Impossible to remove without destroying the motherboard
- Configured at purchase time with no upgrade path
- Typically more expensive when configuring a laptop (you pay upfront for max RAM)
Soldered RAM is usually referred to as LPDDR4, LPDDR5, or LPDDR5X in specs. The “LP” stands for “Low Power,” which is the other main advantage: integrated RAM uses significantly less power than removable SODIMM modules, extending battery life by 20-40% in some cases.
Why Do Manufacturers Use Soldered RAM?
Manufacturers choose soldered RAM for several reasons:
| Reason | Impact | Example |
|---|---|---|
| Thinner Devices | Soldered RAM is integrated into the motherboard, saving space. Removable SODIMM slots take up physical height. | MacBook Air is 11mm thick because RAM is soldered. A traditional clamshell laptop needs 12-15mm. |
| Lower Power Consumption | LPDDR (low-power variants) reduce battery drain and heat. SODIMM modules use standard DDR power levels. | MacBook Air: soldered LPDDR5 provides 18+ hours battery life. Comparable Windows laptop with SODIMM: 12-14 hours. |
| Cost Reduction | Soldering is cheaper than manufacturing dual-channel SODIMM slots. Manufacturers recoup cost by charging for RAM upgrades at purchase. | Upgrading from 8GB to 16GB LPDDR5 costs £80-150 at purchase, but replacement would cost far more (if possible). |
| Reliability | Soldered connections are more stable than removable slots. No risk of RAM becoming unseated or loose over time. | MacBooks have virtually zero RAM-related issues. Windows laptops with SODIMM slots occasionally develop loose-RAM errors. |
Which Laptops Have Soldered (Non-Upgradeable) RAM?
Most modern laptops have soldered RAM. Here’s a breakdown by brand:
Apple (100% Soldered)
All MacBooks and iMacs use soldered LPDDR5/LPDDR5X RAM. You must configure RAM at purchase—there’s no upgrade path whatsoever.
- MacBook Air (M1, M2, M3, M3 Pro): Soldered, configure at purchase (8GB–24GB)
- MacBook Pro (all models): Soldered, configure at purchase (8GB–128GB)
- iPad Pro / iPad Air: Soldered
How to buy: When configuring a MacBook, choose the maximum RAM you’ll need. Resale value is tied to specs, so buying 16GB instead of 8GB costs ~£200 upfront but adds £400+ to resale value.
Microsoft Surface (Mostly Soldered)
Most Surface models use soldered RAM, but a few have partial upgradability:
- Surface Laptop 6 (2024+): Soldered LPDDR5X, not upgradeable
- Surface Laptop 5/4: Soldered, not upgradeable
- Surface Laptop Studio: Soldered LPDDR5, not upgradeable
- Surface Book 3: Mixed—base RAM is soldered, but some configurations allow additional SODIMM upgrade (rare)
- Surface Pro (all): Soldered, not upgradeable
Dell (Mixed)
Dell uses a mix of soldered and SODIMM depending on series:
- XPS 13 / XPS 15 (2023+): Mostly soldered LPDDR5, not upgradeable
- XPS 13 / 15 (2020-2022): SODIMM, upgradeable with up to 64GB
- Dell Latitude 5000 series (business): SODIMM slots, fully upgradeable
- Inspiron 15 / 17 (budget): Usually SODIMM, upgradeable
- Alienware gaming laptops: SODIMM in most models, upgradeable
HP (Mixed)
HP varies by product line:
- Spectre x360 (2023+): Soldered LPDDR5, not upgradeable
- Envy (consumer): Often soldered, especially newer models
- EliteBook (business): SODIMM slots, upgradeable
- ProBook (business): Mixed—some soldered, some SODIMM
- Omen gaming laptops: Usually SODIMM, upgradeable
ASUS (Mostly Upgradeable)
ASUS traditionally keeps SODIMM slots, especially on mainstream models:
- VivoBook (consumer): SODIMM, upgradeable to 32GB or more
- ZenBook (consumer): Mixed—newer models increasingly use soldered
- ROG gaming laptops: SODIMM on most models, upgradeable
- ProArt (professional): SODIMM, upgradeable
- Chromebooks: All soldered (ARM-based)
Lenovo (Mixed)
Lenovo offers both—check the specific model:
- ThinkPad (business): SODIMM on most models, fully upgradeable
- ThinkBook (consumer): Mostly soldered in newer models
- Yoga Slim (consumer): Often soldered
- IdeaPad (budget): Varies—many SODIMM, some soldered
Gaming Brands (ASUS ROG, MSI, Alienware, Razer)
Most gaming laptops keep SODIMM because gamers demand upgradeable systems:
- ASUS ROG Zephyrus: SODIMM, upgradeable
- MSI GS/GP series: SODIMM, upgradeable
- Alienware m15 / m17: SODIMM, upgradeable
- Razer Blade: Mostly soldered in newer models (Razer moved to LPDDR5)
How to Check Before Buying: Is RAM Soldered or Upgradeable?
Method 1: Check the Official Spec Sheet
Look for keywords:
- “Soldered” or “not upgradeable” = Soldered
- “SODIMM” or “expandable to 32GB / 64GB” = Upgradeable
- “LPDDR4 / LPDDR5 / LPDDR5X” = Usually soldered
- “DDR4 / DDR5” = Usually SODIMM (upgradeable), but check
Example spec sheets:
- Dell XPS 13 (2024): “Soldered LPDDR5X-8533 memory… Non-upgradeable”
- Dell Latitude 5540: “16GB DDR5 SODIMM… Supports up to 64GB”
- MacBook Air M3 (2024): “Unified memory 8GB…24GB… Non-upgradeable”
Method 2: Use Online Checker Tools
For specific models, use resources like:
- Crucial System Scanner (scans your laptop, tells you if RAM is upgradeable)
- Dell Support → Specifications (search your model, shows memory type)
- EveryMac.com (for MacBooks—always soldered)
Method 3: Physical Inspection (If You Own It)
If you already own the laptop, you can open it and check:
- Shut down the laptop and disconnect power
- Remove the bottom panel (usually 6-10 screws; watch a YouTube disassembly video for your model)
- Look at the motherboard:
- SODIMM: You’ll see rectangular slots (like RAM slots in a desktop) with small RAM sticks plugged in
- Soldered: You’ll see flat RAM chips directly soldered to the motherboard with no removable module
Safety tip: If you’re not comfortable opening a laptop, take it to a technician or don’t attempt this.
Workarounds for Soldered RAM: What Can You Do?
If you’ve already bought a laptop with soldered RAM and realize you need more capacity, here are your options:
Option 1: Buy Max RAM at Purchase (Recommended)
If you’re buying a new laptop with soldered RAM, configure it with the maximum RAM you can afford. For example:
- MacBook Air M3: Don’t settle for 8GB. Pay the extra £200 to upgrade to 16GB or 24GB. You’ll thank yourself later.
- Dell XPS 13 (2024): Soldered LPDDR5X up to 32GB. If you do video editing, spend the extra money for 32GB upfront.
Option 2: Use Cloud Services as a Workaround
If you’re memory-constrained, offload work to the cloud:
- Large files: Keep projects on cloud storage (Google Drive, OneDrive, Dropbox) and work on them with streaming or web-based tools
- Virtual memory: Use VM/remote computing services (Microsoft Remote Desktop, AWS AppStream, Parsec) to access higher-spec machines
- Compilation/rendering: For CPU-intensive tasks, rent cloud compute (AWS EC2, Linode, Google Cloud) for overnight builds
Option 3: Sell and Upgrade
If you’re a year or two into owning a soldered-RAM laptop and realize you need more, selling and upgrading is often the most practical option:
- MacBook Air 8GB models hold resale value well—you can sell it for 60-70% of original price and put that toward a 16GB model
- Business laptops (ThinkPad, EliteBook) also retain value if they have SODIMM and you can upgrade them before selling
The Future: CAMM2 Standard
The industry is working on a new standard called CAMM2 (Compression Attached Memory Module 2) that promises to bridge the gap between soldered RAM and upgradeable SODIMM.
| Feature | SODIMM | Soldered | CAMM2 |
|---|---|---|---|
| Upgradeable? | Yes | No | Yes |
| Thickness | Thick (needs slot) | Thin (integrated) | Thin (like soldered) |
| Power Efficient? | No (uses DDR5) | Yes (LPDDR5) | Yes (LPDDR5/5X) |
| Timeline | Mature (many laptops) | Current standard | 2025-2026 (emerging) |
CAMM2 adoption: Intel and AMD have announced support for CAMM2 starting in 2025-2026. This could finally give users the best of both worlds: thin, power-efficient laptops with upgradeable RAM. However, adoption will likely take 2-3 years to become widespread.
Real-World Examples: Which Laptop Configurations to Choose
Example 1: MacBook Air (All Soldered)
Scenario: You’re buying a MacBook Air for general work.
- Don’t buy: MacBook Air M3 with 8GB (base)
- Do buy: MacBook Air M3 with 16GB (£+200 upfront, but +£400-500 resale value)
- Reasoning: Soldered RAM can’t be upgraded. Once you have 8GB, you’re stuck. But 16GB will give you 4+ years of usability and much better resale value.
Example 2: Dell XPS 13 2024 (Soldered)
Scenario: You’re a video editor considering XPS 13.
- Don’t buy: XPS 13 with 16GB LPDDR5X (standard config)
- Do buy: XPS 13 with 32GB LPDDR5X (£+400 upfront) or consider XPS 15 with 32GB if available
- Reasoning: 16GB is tight for 4K video editing. With soldered RAM, you need to plan ahead. If budget is tight, buy the older XPS 13 Plus or XPS 15 9530 (previous generation with SODIMM upgradeable to 64GB) used on eBay.
Example 3: ASUS VivoBook 14 (Upgradeable SODIMM)
Scenario: You’re a student on a budget.
- Do buy: ASUS VivoBook 14 with 8GB DDR5 SODIMM (base model, ~£500)
- Plan: In 2-3 years when you need more RAM, upgrade to 32GB (two 16GB sticks, ~£100) yourself
- Reasoning: SODIMM is upgradeable, so you can start cheap and upgrade later. This is far more flexible than soldered RAM.
Key Takeaways
- Soldered RAM cannot be upgraded—configure RAM at purchase time
- Soldered RAM is standard on ultrabooks (MacBook, XPS, Surface, premium laptops) for thinness and battery life
- Business and gaming laptops tend to have upgradeable SODIMM
- Always check before buying: Look for “soldered,” “LPDDR,” or “not upgradeable” in specs
- If buying a soldered-RAM laptop, max out RAM at purchase—it’s cheaper than buying a new laptop later
- CAMM2 is coming (2025-2026) and may offer upgradeable RAM in thin laptops
- For flexibility, prefer SODIMM upgradeable models from brands like ASUS, Lenovo ThinkPad, and HP EliteBook
