4GB DDR3 1600MHz SODIMM upgrade

This A-Tech module adds 4GB of DDR3 memory at 1600MHz with CL11 latency. It uses the 204-pin SO-DIMM form factor and is non-ECC unbuffered. The stick is designed for laptop, notebook and all-in-one systems.

Suits DDR3 laptops needing a 4GB module

Owners of compatible AMD or Intel notebooks can install this single 4GB stick to increase capacity. Systems that require ECC registered memory or a different pin count cannot use this module. Builders needing more than 4GB per slot should look elsewhere.

204-pin DDR3 SO-DIMM form factor

The 204-pin DDR3 SO-DIMM interface determines whether this module fits your laptop. Verify that your system supports DDR3 1600MHz non-ECC unbuffered memory before purchasing.

Questions about this item

Should I pick the 4 GB module or look for a different capacity?

This listing is a single 4 GB DDR3 1600 MHz SO-DIMM; choose it if your laptop has a free slot and supports 4 GB modules, otherwise match the capacity your board accepts.

What does the 1600 MHz speed rating mean once the module is installed?

The module runs at DDR3 1600 (PC3-12800) with CL11 latency; your system will operate it at the highest speed both the memory and the platform support.

Does the 204-pin SO-DIMM interface limit the bandwidth in practice?

The 204-pin DDR3 SO-DIMM form factor carries the PC3-12800 data rate; actual throughput is capped by the laptop's memory controller, not the connector itself.
