RAM Upgrade Checker — How Much RAM Can My Laptop Take?
Find out whether your laptop's memory can be upgraded, how many slots it has, and the maximum RAM it supports. Free, brand-neutral, no download.
I don’t know my laptop model
Windows: press Win+R, type msinfo32, and read “System Model”. To see your slots directly, open Task Manager → Performance → Memory: it reports Slots used: 1 of 2 and the form factor.
macOS: Apple menu → About This Mac. Any Apple Silicon Mac (M1 and later) has soldered memory and cannot be upgraded.
Linux: run sudo dmidecode -t memory.

Why most laptops can’t be upgraded any more
For most of the last two decades, laptop memory came on removable SO-DIMM sticks and adding more was a ten-minute job with one screwdriver. That is no longer the default. To make machines thinner, manufacturers increasingly solder the memory chips directly to the mainboard, where there is nothing to remove and nothing to add. Whatever you bought is what you keep.
This checker answers the question honestly for 3,284 laptop models: whether the memory is socketed or soldered, how many slots exist, and what the real ceiling is.
Soldered, socketed, and the confusing middle
A socketed laptop has one or more SO-DIMM slots. You can replace a stick with a larger one, or fill an empty slot. A soldered laptop has memory chips fixed to the board — every Apple Silicon Mac, and most thin-and-light Windows laptops since roughly 2018. A surprising number of machines are both: some memory soldered down, plus a single free slot. Those are upgradeable, but only up to a lower ceiling than the spec sheet implies.
Why we sometimes refuse to answer
Our data comes from tens of thousands of real hardware reports. Where those reports agree overwhelmingly, we publish an answer. Where they contradict one another — usually because one model name covers several different configurations — we say so instead of guessing. An incorrect “yes, you can upgrade” costs you a memory stick that does not fit, so we would rather tell you nothing than tell you something wrong.
How to check your own machine in thirty seconds
On Windows, open Task Manager, choose the Performance tab, and click Memory. It reports Slots used: 1 of 2 and the form factor directly — that single screen tells you whether you have a free slot. On Linux, sudo dmidecode -t memory prints the same information. On a Mac, there is nothing to check: if it has an M-series chip, the memory is soldered.
