How to use
Power down the computer and disconnect it from any power source before installing the memory module. For laptops, remove the access panel or back cover as described in the device manual to expose the SO‑DIMM slot. For desktops, open the case to access the DIMM slots on the motherboard. Align the notch on the module with the slot key, insert at an angle (for SO‑DIMM) or straight in (for DIMM) and press gently until the retaining clips engage. Replace any covers, reconnect power, and start the system. Verify that the operating system recognizes the additional memory in the system or BIOS/UEFI settings.
Usage recommendations
Install memory modules in matched pairs where supported by the motherboard to enable dual‑channel mode. Refer to the system or motherboard manual for supported memory speeds, maximum supported capacity, and slot population order. If upgrading a laptop, confirm the required form factor (SO‑DIMM) and the maximum per‑slot capacity before purchase.
