4GB DDR3 SODIMM for laptops and NAS

This module adds four gigabytes of DDR3 1600 memory to laptops, all-in-one PCs and compatible NAS units. It targets users who need a straightforward capacity increase without changing voltage or form factor. The 204-pin SO-DIMM fits standard DDR3 slots in those device classes.

JEDEC-compliant 1.5V unbuffered design

The stick follows JEDEC PC3-12800 timings at CL11 and runs at the standard 1.5 volts. Because it is non-ECC and unbuffered, it works in consumer platforms that do not support registered or error-correcting modules. RoHS compliance means the components meet restricted-substance rules.

Simple slot insertion with matching specs

Installation consists of aligning the notch on the 204-pin edge connector and pressing until the side clips engage. Most issues arise when the host system requires a different voltage, a higher density per rank, or an ECC module, so verifying the device manual before purchase avoids returns.

Questions about this item

Will the module need a heat spreader added later for sustained loads?

No heat spreader is included or required; the DDR3 1600 CL11 1.5V SODIMM runs within JEDEC thermal limits without one.

What limit appears first when the memory runs continuously at 1600 MHz?

The CL11 latency at 1.5V is the governing timing constraint under sustained DDR3 1600 operation.

How much heat and power does the 4 GB stick produce during all-day use?

At 1.5V the module draws minimal power and generates low heat typical for a non-ECC DDR3 1600 SODIMM.
