OWC 8GB DDR3L 1600 SODIMM for Vostro laptops

This module adds eight gigabytes of DDR3L memory to compatible Dell Vostro notebooks. It targets owners of the 3558, 3559, 5459 or 5480 models who need more capacity for multitasking. The stick runs at 1600 MHz with CL11 latency and operates at the low 1.35 volt level defined for DDR3L.

Fits 204-pin DDR3L slots in select Vostro chassis

Installation requires an available SODIMM socket that accepts 204-pin DDR3L modules. The unbuffered, non-ECC design matches the original specification for these systems. Adding this module frees the existing slot for a second upgrade if the platform supports dual-channel operation.

Sustained operation at JEDEC-standard voltage

The module maintains its rated 1600 MHz speed and CL11 timings under continuous load without exceeding 1.35 volts. JEDEC compliance and ROHS certification ensure stable behaviour during extended sessions. The 2Rx8 organisation provides consistent bandwidth for long-running workloads.

Questions about this item

Does the 1.35V DDR3L 1600 module throttle under sustained load without a heat spreader?

The module runs at the JEDEC-standard 1.35V, so thermal throttling is not expected in the supported Dell Vostro 3558, 3559, 5459 or 5480 chassis under normal sustained workloads.

How much heat or fan noise does this 8GB SODIMM add during all-day use?

With no heat spreader and a low 1.35V operating voltage, the stick adds negligible heat; any extra fan activity will come from the CPU or GPU, not from the memory itself.

Must the laptop already have a free 204-pin DDR3L slot to install this 8GB stick?

Yes — the upgrade requires an available 204-pin DDR3L SODIMM slot in a compatible Dell Vostro 3558, 3559, 5459 or 5480.
