How to use
Before installing, power down the computer, disconnect power, and follow anti-static precautions. Consult the system or motherboard manual to confirm compatible memory types and slot population rules. Open the memory compartment or access panel, unclip the existing module(s) if replacing or insert into an empty DDR4 slot aligning the notch, and press firmly until the module seats and retention clips engage. Reassemble the system, reconnect power, and verify that the BIOS/UEFI and operating system recognize the full 8GB module. If the system does not boot or recognize the memory, recheck seating, slot compatibility, and whether the platform supports single rank modules at 2400MHz.
Usage recommendations
Install memory modules in matched pairs where the system supports dual-channel operation for improved bandwidth. When mixing modules, use the same capacity, speed (2400MHz), and preferably the same brand and timings to minimize compatibility issues. Keep system BIOS/UEFI firmware up to date to ensure proper memory detection and stability.
