CAMM2 RAM Just Arrived… What Are Its Pros and Cons?

Desktop and laptop RAM for years looked very similar — long straight bars called DIMMs or SO-DIMMs.
There's now a new kid in the mix: CAMM2, or Compression Attached Memory Module (version 2).
It's a fresh new layout that claims to substitute for SO-DIMMs in laptops and maybe even desktops one day.
Let's look at what makes CAMM2 different, what is well in CAMM2, and what holds CAMM2 back.

What is CAMM2?

CAMM2 is a new RAM form factor that is mounted on the motherboard through compression contacts rather than slot connectors.
This means the RAM module is compressed flat and screwed in contrast to being angled in like a stick.
The approach makes it:

• Thinner than SO-DIMMs

• More stable at high speeds

• Easier to upgrade than soldered RAM

Advantages of CAMM2

Here's why CAMM2 is better:

• Super Thin Design – The module is flat on the motherboard, with space for cooling and battery.

• More Capacity Support – It accommodates bigger RAM sizes per module (think 64GB or even 128GB in laptops).

• Better Signal Integrity – Shorter electrical paths mean faster data transfer and less latency.

• Replaceable RAM on Thin Laptops – Manufacturers can now ditch soldered memory without sacrificing thin form factors.

• Future-Proof for DDR5 and Beyond – CAMM2 supports newer and future DDR standards.

Disadvantages of CAMM2

Of course, there's a catch — here's what might make you wait until later:

• Limited Support – CAMM2 is supported in only a limited number of laptops and motherboards currently.

• Single Slot Issue – Certain machines will use one CAMM2 slot, which means full replacements for upgrades.

• Screw-Based Installation – Not so easy as putting in a SO-DIMM; you'll be needing a screwdriver.

• New Standard Growing Pains – Parts availability and compatibility may be a hassle for the moment.

Should You Upgrade Now?

If you're buying a new ultra-thin notebook with CAMM2 support — go ahead.
It's faster, cooler, and maintains upgradeability in fresh designs.
If you already have a desktop or laptop with DDR4/DDR5 SO-DIMMs, however, no need to panic.
Wait until:

• CAMM2 becomes more common

• Prices decrease

• Motherboards and laptops fully embrace it

 

Conclusion

CAMM2 is the future of laptop memory — no doubt.
It solves the biggest issue with fresh thin laptops (soldered RAM) and boosts performance and efficiency.
Still, it’s a bit early for everyone to jump on board.
If you’re into future-proof setups or love trying new hardware, CAMM2 is worth watching closely.
