4GB DDR3L SO-DIMM for laptop upgrade

This SK hynix module provides 4GB of DDR3L memory in a 204-pin SO-DIMM form factor. It runs at 1600MHz with a low 1.35V operating voltage. The stick is unbuffered and non-ECC, matching standard laptop memory requirements. It is designed specifically for notebook computers.

Fits DDR3L 1600MHz slots; not for other memory types

This module suits owners of laptops that accept DDR3L SO-DIMMs and need a 4GB stick to fill a slot or replace a failed unit. Builders whose systems require a different memory generation, voltage, or pin layout should look elsewhere. The 1.35V specification is a key compatibility factor. Check your device manual before ordering.

1.35V DDR3L voltage decides compatibility

The single specification that determines whether this is the right part is the 1.35V DDR3L voltage combined with the 1600MHz speed rating. Systems specified for standard 1.5V DDR3 or other memory types will not work correctly with this module. Verify that your laptop explicitly supports DDR3L at this voltage.

Questions about this item

Will the 204-pin DDR3L SO-DIMM need any maintenance or replacement over time?

The module has no moving parts and no user-serviceable components. Under normal laptop use it simply runs until the system is retired; no periodic maintenance is required.

What limit appears first when the 1.35 V 1600 MHz module runs under sustained load?

The JEDEC-rated 1600 MT/s speed and 1.35 V operating voltage are the fixed electrical limits; the memory controller will not exceed them during continuous operation.

How much heat or noise does the 4 GB unbuffered DDR3L stick produce when the laptop runs all day?

The low-voltage 1.35 V design generates minimal heat and has no fan or moving parts, so it adds no audible noise to the system.
