4GB DDR3 SODIMM upgrade

This 4GB DDR3 1600MHz SODIMM module adds memory capacity to compatible laptops, notebooks and all-in-one systems. It replaces Samsung M471B5173 series modules and suits users who need a straightforward capacity increase for everyday workloads.

204-pin DDR3 laptop fit

The module uses the standard 204-pin DDR3 SO-DIMM form factor and operates at 1.5V without ECC or buffering. It installs directly into a free DDR3 SO-DIMM slot and requires no additional configuration beyond verifying the system's supported memory specifications.

4GB single-module headroom

A single 4GB stick handles typical office applications, web browsing and light multitasking. Systems that demand more than 4GB of total memory or that require dual-channel bandwidth will need additional modules or a higher-capacity kit.

Questions about this item

What limits the A-Tech 4GB DDR3 1600 SODIMM under sustained use?

The module runs at 1.50V standard DDR3 voltage with CL11 latency; sustained workloads are bound by the 1600MHz data rate and single 4GB capacity.

How much heat or power does the A-Tech 4GB DDR3 1600 SODIMM produce when running all day?

Operating at 1.50V DDR3 standard voltage, the unbuffered non-ECC module draws minimal power and generates low heat typical for 204-pin SODIMM laptop memory.

What must my laptop already have for this A-Tech 4GB DDR3 1600 SODIMM to work?

Your system needs a free 204-pin DDR3 SO-DIMM slot supporting 1600MHz PC3-12800 operation at 1.50V with non-ECC unbuffered memory.
