4 GB DDR4 3200 MHz module

This 4 GB DDR4 SO-DIMM runs at 3200 MHz with a PC4-25600 bus speed. It is built for laptops that need a straightforward memory upgrade. The single-rank 1Rx16 layout keeps compatibility simple for mainstream notebooks. Buyers who need higher capacities should look elsewhere.

Sustained load behaviour

The module operates at the rated 3200 MHz under continuous workloads without additional cooling. Standard DDR4 voltage keeps power draw predictable during long sessions. Latency remains consistent because the single-rank design avoids interleaving delays. Systems with limited airflow will not see thermal throttling from this stick.

Upgrade context

This stick replaces an existing 4 GB DDR4 module or fills an empty SO-DIMM slot in a compatible laptop. The jump is worthwhile when the current memory runs slower than 3200 MHz or when dual-channel capacity is needed. Machines that already run matched 3200 MHz pairs gain no benefit from this single unit.
