Key specifications
 Capacity: 8 GB
 Memory type: DDR4
 Form factor: 260-pin SO-DIMM
 Error correction: ECC (Error-Correcting Code)
How to use
Power down the host device and disconnect it from mains power before installing the memory module. Locate the SO-DIMM slot on the motherboard or expansion board, align the module with the notch in the slot, and insert it at the correct angle until the retaining clips engage. After installation, reconnect power and boot the system; verify that the operating environment recognizes the additional 8 GB of memory and that ECC functionality is active if supported by the platform. Follow the device manufacturer's service manual for any platform-specific steps or compatibility lists.
Usage recommendations
Install the module in a compatible slot and, when possible, use matched modules (same capacity, type, and speed) for dual-channel or multi-channel configurations. Check the host device documentation for supported memory maximums and ECC support. Handle the module by its edges and avoid static discharge by using proper ESD precautions during installation.
