Computer memory (RAM) for laptops and desktops

Upgrade your computer memory for work, gaming or running several applications at once. Browse Kingston, G.Skill, Lexar, Silicon Power and Synology modules at TechArena. Choose DDR3, DDR4 or DDR5 memory to match your device, required capacity and speed.

How to choose compatible RAM

Check the DDR generation and form factor. DDR3, DDR4 and DDR5 are not interchangeable. Laptops often use SO-DIMM modules and desktops use DIMMs, but always check your specific device. Some computers have soldered memory that cannot be replaced.

Compare total capacity and kit contents. 32 GB may mean one 32 GB module or a kit of two 16 GB modules. Check available slots, maximum supported capacity and the memory configurations recommended by the device manufacturer.

Memory speed and compatibility

Filter by DDR generation, capacity, form factor, data rate and brand. Enter an exact product model or part number in the category search. Advertised speeds may depend on the processor, motherboard and support for XMP or EXPO profiles. For NAS devices and servers, also check ECC and registered memory requirements; the DDR generation alone does not guarantee compatibility. Contact the TechArena team with your computer or motherboard model if you need help choosing.
