It depends on the laptop — but likely yes.

Probably, but check your laptop’s specs first.

Most laptops with soldered RAM have one empty SODIMM slot. If yours does, you can usually add a 32GB stick for a total of 48GB (16 + 32). But not all laptops support that much RAM in one slot — some cap at 16GB or 32GB per slot. Look up your exact model on the manufacturer’s site or a forum like Notebookcheck to confirm.

Keep in mind: mixing capacities means you lose full dual-channel performance. The first 16GB of that 32GB stick will run in dual channel with the soldered 16GB, but the remaining 16GB will run single-channel. For most real-world tasks, you won’t notice the difference. For memory-intensive work like video editing or VMs, it’s still a massive upgrade over 16GB total.

Don’t just buy a stick without verifying. Laptop RAM also has specific speeds and voltages (usually DDR4 or DDR5, 1.2V or 1.1V). Crucial’s compatibility tool or a quick Google with your model number will tell you exactly what works.
