CAMM2 RAM Explained — The New Laptop Memory Standard

CAMM2 RAM is a new laptop memory standard that’s starting to appear in premium workstations and high-end laptops. If you’re shopping for a powerful laptop or wondering whether your current machine can be upgraded, you need to understand what CAMM2 is, how it works, and whether it’s right for you.

In this guide, we’ll explain the technical differences between CAMM2, SO-DIMM, and LPDDR memory, show you which laptops use it today, and help you decide whether to wait for CAMM2 or upgrade to traditional SO-DIMM now.

What Is CAMM2 RAM?

CAMM2 stands for Compression Attached Memory Module 2. It’s a new form factor developed by JEDEC (the Joint Electron Device Engineering Council) specifically designed for thin and ultraportable laptops.

Unlike traditional SO-DIMM modules that sit vertically in a slot, CAMM2 modules lie flat against the motherboard, held in place by a sliding compression mechanism. This design allows manufacturers to:

• Save space inside thin laptops
• Use a single module to achieve dual-channel performance (instead of requiring two SO-DIMMs)
• Pack higher memory density into smaller form factors
• Make the module upgradeable (unlike soldered LPDDR)

CAMM2 is the successor to CAMM (the original version), which saw limited adoption. CAMM2 improves on the original with better thermal performance and broader JEDEC standardisation.

CAMM2 vs SO-DIMM vs LPDDR — Key Differences

To understand why CAMM2 matters, you need to know how it compares to the two memory types currently dominating laptops: SO-DIMM and LPDDR.

The CAMM2 Advantage Over LPDDR

LPDDR memory (Low Power DDR) is soldered directly onto the motherboard, which means it cannot be upgraded. This is a huge limitation if you buy a laptop with 16GB and later realise you need 32GB. With CAMM2, you get the thin form factor of LPDDR combined with the upgradeability of SO-DIMM.

The CAMM2 Advantage Over SO-DIMM

SO-DIMM requires two modules to achieve dual-channel performance (which roughly doubles memory bandwidth). CAMM2 achieves dual-channel with a single module, saving space and cost. For manufacturers building ultra-thin workstations and professional laptops, this is a significant win.

Which Laptops Use CAMM2 RAM?

CAMM2 adoption is still in its early stages, but several high-end manufacturers have committed to the standard. Here’s what’s available as of 2026:

Dell Precision

Dell Precision 5680 (and 5690) — Premium mobile workstations designed for architects, engineers, and video editors. These models come with CAMM2 as the standard memory option, with configurations up to 96GB.

Lenovo ThinkPad

Lenovo ThinkPad P1 Gen 7 — Professional workstation laptop that supports CAMM2 modules. Known for excellent build quality and business-focused features.

More Brands Coming Soon

JEDEC’s standardisation of CAMM2 in 2024–2025 means other manufacturers (likely including HP, Asus, and others) are expected to introduce CAMM2-equipped models in 2026 and beyond.

CAMM2 Advantages and Disadvantages

Advantages

• Upgradeable + Thin — You get the best of both worlds: laptop thinness like LPDDR, but with upgrade capability like SO-DIMM.
• Single Module for Dual-Channel — One CAMM2 stick gives you dual-channel performance, saving space and cost compared to dual SO-DIMM setups.
• Future-Proof — JEDEC standardisation means more manufacturers will support it, and more modules will be available.
• Better for Professionals — Especially useful for workstations where 32GB or 64GB memory is common.

Disadvantages

• Very Limited Availability — Only a handful of laptops currently support CAMM2, and choices are limited to premium brands.
• Expensive — CAMM2 modules are significantly more costly than equivalent SO-DIMM modules (expect £100–200+ for 32GB).
• Fewer Brand Options — You’re currently limited to a small number of manufacturers. Kingston, Corsair, and Crucial are exploring CAMM2, but supply is tight.
• No Consumer Ultrabooks Yet — CAMM2 is currently found only in professional workstations, not mainstream consumer laptops.
• Cooling Concerns — Flat, horizontally-mounted memory may present thermal challenges in some designs (though this is being addressed with Gen 2 modules).

Should You Buy a CAMM2 Laptop?

Whether CAMM2 is right for you depends on your use case:

Buy CAMM2 If You:

• Need a professional workstation (3D design, video editing, data science)
• Want to upgrade to 64GB or 96GB in the future
• Prioritise ultra-thin form factor without sacrificing upgradeability
• Are willing to pay a premium for the latest technology

Stick with SO-DIMM If You:

• Are buying a consumer or business laptop (not a workstation)
• Want a wider range of laptop choices
• Need affordable upgrade options
• Plan to upgrade in the next 2–3 years

For most users, traditional DDR4 or DDR5 SO-DIMM remains the practical choice. However, if you’re investing in a professional-grade workstation, CAMM2 is worth considering.

CAMM2 Module Availability and Pricing

If you own or are considering a CAMM2-compatible laptop, here’s what’s currently available:

Kingston has released several CAMM2 modules, including configurations from 16GB to 64GB. Corsair and Crucial are also developing CAMM2 options, though availability remains limited. Expect to pay:

• 16GB CAMM2: £70–90
• 32GB CAMM2: £140–180
• 48GB CAMM2: £200–250
• 64GB CAMM2: £250–300+

Prices are higher than equivalent SO-DIMM modules, partly due to limited production and the premium placed on these early-adopter products.

Where to Buy CAMM2

CAMM2 modules are available through specialist retailers. Check Amazon UK for current availability and pricing, or contact your laptop manufacturer’s authorised service partners for OEM-approved modules.

The Future of CAMM2

CAMM2 adoption is expected to accelerate significantly in 2026–2027 as:

• JEDEC standardisation encourages broader manufacturer support
• More laptop brands launch CAMM2-equipped models
• Production volume increases and module prices fall
• Industry momentum shifts away from non-upgradeable LPDDR

If you’re buying a laptop today, CAMM2 may still be too niche. But in 18–24 months, it could become the standard for professional and high-end consumer laptops.
