4 GB DDR4 2133 SO-DIMM

This SK hynix module delivers 4 GB of DDR4 memory at 2133 MHz with a CL15 latency. It uses the standard 260-pin SO-DIMM form factor and runs at 1.20 V. The stick is unbuffered and non-ECC, making it a direct drop-in upgrade for compatible laptops.

Ideal for capacity upgrades

The single 4 GB stick suits owners of DDR4 laptops that have a free slot and need more memory for everyday multitasking. Buyers whose machines require ECC or registered memory should look elsewhere, as this module provides neither. Systems limited to a maximum of 4 GB total will not benefit from adding this unit.

260-pin DDR4 SO-DIMM interface

The module fits only laptops that accept 260-pin DDR4 SO-DIMMs operating at 1.20 V. Verify that your device supports DDR4-2133 (PC4-17000) and unbuffered, non-ECC memory before purchasing.

Questions about this item

Will the 260-pin SO-DIMM fit my laptop's DDR4 slot?

Yes, the 260-pin DDR4 SO-DIMM form factor matches the standard laptop memory slot for this generation.

What is the correct way to seat the module so it locks in place?

Align the notch with the slot key, insert at an angle, then press down firmly until both side clips click audibly.

Does this 1.20 V unbuffered module need any firmware updates or periodic replacement?

No firmware is required; the module is maintenance-free and only needs replacement if a fault develops or capacity becomes insufficient.
