Buying a laptop with soldered RAM is rarely the mistake in itself. Buying too little of it is. Soldered and on-package LPDDR5X memory is faster and more power-efficient than a removable SO-DIMM, and on most thin business laptops it's the only option. Once you buy, though, the capacity is fixed for the life of the machine. If a fleet is kept four or five years and its users outgrow 16GB in year three, nobody can add memory: you replace the laptop early or live with a slow one. In 2026 there's a third route on a handful of models. LPCAMM2 is a removable module that keeps most of the LPDDR5X advantage. So "biggest mistake" overstates it. The real risk is ordering a soldered laptop's memory as if you could fix it later.
We looked at this for ThinkPads specifically in Your Expensive ThinkPad Has Soldered RAM. Is That a Dealbreaker in 2026? This post takes the cross-brand, whole-fleet view.
What kinds of laptop memory are there now?
| Memory type | Example 2026 models | Speed (MT/s) | Upgradeable? | Main trade-off |
|---|---|---|---|---|
| On-package LPDDR5X | Intel Lunar Lake laptops (e.g. ThinkPad X1 Carbon Gen 13, T14 Gen 6 Lunar Lake); Apple silicon Macs | 8,533 on Lunar Lake | No; 16GB or 32GB only on Lunar Lake | Best battery life; capacity fixed at purchase |
| Soldered LPDDR5X on the board | ThinkPad X1 Carbon Gen 14, T14s Gen 7, Dell Pro 7 14; some HP EliteBook 8 G2 SKUs | 7,467–9,600 | No; up to 64GB | Must order final capacity up front |
| LPCAMM2 module | ThinkPad T14 Gen 7 / T16 Gen 5 (Intel), Dell Pro 5 14 | 6,800–8,533 | Yes, one module | Few models; module cost |
| DDR5 SO-DIMM | ThinkPad T14 Gen 7 (AMD), E14 Gen 8, HP EliteBook 6 G1i | 5,600 | Yes, two slots, up to 64–96GB | Slower, uses more power, thicker |

Why do manufacturers solder the memory?
Mostly for speed, battery life and thinness. Soldered LPDDR5X runs at 7,467–9,600 MT/s on current ThinkPads, against DDR5-5600 on SO-DIMM models. Intel says putting memory on the processor package in Lunar Lake cut memory interface power by about 40%. Micron, which makes LPCAMM2 modules, claims they use up to 61% less active power than SO-DIMMs and take up to 64% less space. Those are vendor figures, but the direction is consistent across sources.
There's also a counter-trend. Intel's then-CEO Pat Gelsinger called Lunar Lake's on-package memory "a one-off", and Intel's Panther Lake chips (Core Ultra series 3) moved memory back off the package, with support for DDR5, LPDDR5 and LPCAMM2 at up to 9,600 MT/s. That gives laptop makers room to offer upgradeable memory again without giving up LPDDR speeds.
Where does soldered RAM become a fleet problem?
The risk grows with how long you keep machines. Gartner expects business PC lifetimes to stretch about 15% in 2026 as memory costs push refreshes back (via ITPro, February 2026). A laptop you planned to keep three years may now stay five. Three things follow.
You can't extend a laptop's life with memory. On an SO-DIMM or LPCAMM2 laptop, adding memory in year three costs a module and ten minutes; iFixit rates the T14 Gen 7's LPCAMM2 swap "Easy". On a soldered laptop that option doesn't exist.
Getting it right up front costs real money. On SourceIT's current listings, the same laptop costs S$540 to S$709 more with 32GB than with 16GB. A Dell Pro 5 14 with a Core Ultra 7 355 goes from S$2,528.81 to S$3,068.88, and an HP EliteBook 8 G2i 14 with a Core Ultra 5 325 from S$3,137 to S$3,846 (listed 8 Nov 2026). On a 50-laptop order, that's S$27,000 to S$35,450 decided at purchase.
The same model name can hide both types. Lenovo's T14 Gen 7 uses LPCAMM2 on Intel and two SO-DIMM slots on AMD. HP's EliteBook 8 G2 line has soldered and upgradeable SKUs. Procurement has to check each part number, not the series name.
Soldered memory isn't the mistake. Ordering it as if you could fix it later is.
When is soldered RAM perfectly fine?
If you replace laptops on a three-year cycle or lease them, nobody upgrades memory anyway, so soldered costs you nothing. It's also fine when you size it correctly: 16GB for typical office, email and Teams work (Microsoft's Copilot+ PC minimum), and 32GB for analysts, heavy multitaskers, developers and anyone running local AI or virtual machines. We discuss how far 16GB stretches in The 16GB Laptop Is Becoming a Bad Business Investment.
An upgradeable laptop isn't automatically better either. An 8GB machine with one SO-DIMM runs single-channel and can feel slower than a soldered 16GB dual-channel laptop. And upgrades aren't cheap in 2026: a 16GB DDR5 SO-DIMM is S$411.25 on our store, which still undercuts the factory step to 32GB, but only on a laptop with a free slot.
How should you buy soldered-RAM laptops?
- Decide the keep period first. Three years or less: buy for today. Four to five years: buy for year four.
- Tier by role. Give 32GB to the roles that need it, not to everyone, so the premium lands where it pays back. Thin-and-light models carry other trade-offs too, covered in Are Ultra-Thin Business Laptops Sacrificing Too Much for Design?
- Check memory type per part number. Look for "LPCAMM2", "SO-DIMM" or "soldered/on-board" on the spec sheet.
- Prefer LPCAMM2 where it's offered if you want LPDDR5X speed and a later upgrade path.
- Don't count on resale value either way. We found no reliable data on whether soldered memory affects resale prices.

Buying in Singapore
SourceIT lists 16GB and 32GB versions of the same business laptops side by side, so you can see the premium before you decide. Examples: the Dell Pro 5 14 with 16GB and with 32GB; the HP EliteBook 6 G2i with 16GB (S$2,704) and with 32GB (S$3,340). The ASUS NUC 16 PRO mini PCs use LPDDR5 memory, so the same rule applies to desktops: the 32GB model is S$2,775.81 and the 64GB model S$4,281.65. For SO-DIMM laptops, the G.SKILL Ripjaws DDR5-5600 16GB SO-DIMM is S$411.25. We don't currently list LPCAMM2 modules; ask us. Prices change; ask for a current quotation.

Frequently asked questions
Is soldered RAM slower or worse than removable RAM? No, it's usually faster. Soldered LPDDR5X runs at 7,467–9,600 MT/s on current ThinkPads, against 5,600 MT/s for DDR5 SO-DIMMs, and uses less power. The downside is that you can't upgrade it.
What is LPCAMM2? A removable memory module standard (JEDEC CAMM2, published December 2023) that uses LPDDR5X chips. It gives close to soldered-memory speed with the option to swap or upgrade the module. In 2026 only a few business laptops use it, such as Intel versions of the ThinkPad T14 Gen 7 and the Dell Pro 5 14.
How much RAM should I buy on a soldered laptop? Size for the last year you'll keep it. 16GB suits typical office work; 32GB suits heavy multitaskers, analysts, developers and local AI users. If you lease or refresh every three years, buy for today's needs.
Can I tell from the model name whether RAM is soldered? Not reliably. The ThinkPad T14 Gen 7 uses LPCAMM2 on Intel and SO-DIMMs on AMD, and some HP EliteBook 8 G2 SKUs differ. Check the spec sheet for the exact part number.
Do Macs have upgradeable memory? No. Apple silicon Macs put memory on the chip package, so capacity is fixed when you order.
