Laptop DDR4 SO-DIMM 4GB 3200MHz

This SK hynix module adds 4GB of DDR4 memory to compatible laptops. It runs at 3200MHz with a PC4-25600 bus and operates at 1.2V. The 260-pin SO-DIMM form factor fits standard laptop slots. Non-ECC unbuffered design suits mainstream mobile platforms.

Ideal for single-slot capacity upgrades

Users needing a single 4GB stick to fill an empty slot or replace a failed module will find this a direct match. Builders who require ECC error correction, registered buffering, higher capacities per stick, or desktop DIMM form factors should look elsewhere.

1Rx16 rank organisation determines compatibility

The module uses a single-rank 1Rx16 layout, which some laptop memory controllers treat differently from dual-rank or x8 parts. Verify the original part number against the listed compatibles such as L83673-005 or L34198-371 before ordering.
