Cheapest 16 GB DDR5 laptop RAM (SO-DIMM)
16 GB DDR5 SO-DIMM memory is a stick of RAM made for the smaller memory slots found in laptops and many compact desktops. It gives your system room to keep apps, browser tabs, and documents in active use at the same time. Before you buy, check three things: the form factor (SO-DIMM, not a full-size DIMM), the memory type (DDR5, which is not interchangeable with DDR4 or DDR3), and what your specific device supports.

Before you buy
- Confirm the form factor and type first. A full-size desktop DIMM will not fit a laptop slot, and DDR5 is not backward compatible. Some devices also have memory soldered to the board with no free slot, so check your device's memory configuration before ordering anything.
- Think about slots and pairing. Many laptops and small desktops offer two memory slots. If both are available, two matched sticks can let the memory run in dual-channel mode, which can help performance. Also check whether one slot is already filled and how much total memory your device supports.
- Choose capacity for the life of the device, not just now. Consider what you run day to day and what you expect to run later, then check the maximum supported capacity. Larger sizes such as 48 GB, 64 GB, and 96 GB are not supported everywhere, and slots may already be partly occupied.
Questions
Will 16 GB DDR5 SO-DIMM memory fit in my laptop or small desktop?
SO-DIMM is the shorter module used in most laptops and in many compact desktops and tiny workstations. A full-size DIMM will not fit those slots. It is DDR5, so it does not work in slots designed for DDR4 or DDR3. Our catalog currently shows 25 devices that accept this part, including the Dell XPS 15 9520, Dell Latitude 5440 and 5450, Dell OptiPlex 7000 Micro, Dell G15 5520, Framework Laptop 13 (AMD Ryzen 7040), Framework Laptop 16, Lenovo ThinkCentre M70q Gen 6 Tiny (Intel), Lenovo ThinkCentre M75q Gen 5 Tiny (AMD), and Lenovo ThinkStation P3 Tiny Gen 2 (Intel). If your device is not on the list, check its memory specifications or contact the manufacturer before buying.
Does memory speed matter, and which speed should I choose?
DDR5 memory is rated at different speeds, usually shown in MT/s. Your device runs memory at a speed it supports, so a module rated faster than your system can use may simply run at a lower speed. Check the memory specification your device lists before paying extra for a higher rating. If you install two sticks with different speeds, the system generally runs both at the speed of the slower one. Matching sticks are usually the simplest choice.
Is it safe to buy used or refurbished memory?
Used memory can cost less, but you are buying someone else's history. Whether it is new or used, look for clear photos of the label and contacts, a stated test or working condition, and a return policy in case the module does not work with your device. New memory usually includes a warranty and known provenance. Memory can fail like any component, so the option to return or exchange matters in both cases.
How much RAM do I actually need?
For everyday work such as web browsing with several tabs, office apps, email, and streaming, 16 GB is the size most people start with. More memory helps if you keep many apps open at once, work with large files or spreadsheets, do creative work, develop software, or run virtual machines. Before stepping up to 32 GB, 48 GB, 64 GB, or 96 GB, check how much your device supports and how many slots are free. You can compare all of these sizes on PartsPrices.
