Frequently asked questions
What type of memory does my laptop use?
Most modern laptops use SO-DIMM (Small Outline Dual Inline Memory Module) modules. DDR4 and DDR5 laptops use SO-DIMM, but they are not interchangeable - check your laptop's specifications to determine which generation you need. Some ultra-thin laptops have soldered memory that cannot be upgraded.
How do I check if my laptop memory can be upgraded?
Check your laptop's specifications or user manual. Many laptops have one or two accessible memory slots, while some have soldered memory. You can also use system information tools like CPU-Z or check the manufacturer's website for upgrade options. Some laptops have memory under the keyboard or require removing the bottom panel.
What's the difference between laptop and desktop memory?
Laptop memory (SO-DIMM) is physically smaller than desktop memory (DIMM). SO-DIMM modules are about half the length of DIMM modules. They use the same DDR technology (DDR4, DDR5) but are not interchangeable - you cannot use desktop memory in a laptop or vice versa.
