Rules that apply across these laptops
- Match the generation. These laptops use DDR5 (262-pin) SODIMM, which will not fit DDR4 slots.
- Install matched modules. Identical modules in pairs run in dual-channel mode; the Helios 18 AI takes four.
- Respect the maximum. Each listing is built up to the maximum Acer lists for the model, and no further.
- The processor sets the speed. Acer does not publish a module speed on its US site, so modules run at the speed the processor and module count support.
Frequently asked
What memory does an Acer Predator Helios laptop take?
The Predator Helios models listed here use non-ECC DDR5 SODIMM. Most have two SODIMM slots; the Helios 18 AI has four. Each listing states the maximum Acer lists for that model.
Can I upgrade a Predator Helios Neo 14 AI or a Predator Triton 14?
Not these. The Helios Neo 14 AI, Triton 14 AI and Triton 14 use memory soldered to the board, and Acer lists no memory expansion for them, so they are not listed.
Does Acer publish the memory speed?
Not on its US site. The listings use DDR5-5600 SODIMM, which runs at the speed the processor and the number of modules installed support. For the Helios 18 AI, Acer's support documentation lists up to 4400 MT/s with four modules installed.
Why do the Helios Neo 16 and Neo 18 AI stop at 32GB?
Acer's US specifications list a 32GB maximum for these models, so the listings are built to that figure. Some third-party sites list 64GB; send us your exact model if you want us to confirm what fits.
How do I find my model number?
The model code, for example PH18-73 or PHN18-72, is on the label on the bottom of the laptop and in the Windows system information.
