System-specific SO-DIMM upgrade

This 4 GB DDR3L module is built for Toshiba Satellite L755-S5281, L755-S5349 and L755-S5356 notebooks. It installs in a single 204-pin slot and runs at 1.35 V to match the platform's low-voltage requirement. The unbuffered, non-ECC design keeps latency low for everyday workloads.

4 GB capacity with DDR3L 1600 speed

The stick delivers PC3L-12800 bandwidth at CL11 11-11-11 timings, handling web browsing, office suites and media playback without bottlenecks. Memory-intensive tasks such as virtualisation or large media editing will exhaust the 4 GB limit and the system's two-slot 8 GB maximum.

Drop-in fit for listed Satellite models

No heat spreader means it clears tight chassis spaces and sits flush under the keyboard deck. One module occupies a single slot, leaving the second free for a matching 4 GB stick to reach the 8 GB ceiling. Buyers needing more than 8 GB or a different DDR generation must choose another platform.

Questions about this item

Will this 204-pin DDR3L 1600 module run reliably in a Satellite L755-S5281 that currently uses 1333 MHz sticks?

The module is rated for DDR3L 1600 at 1.35 V with CL11 timing; the L755 platform will simply clock it down to 1333 MHz while keeping the lower voltage, so it works alongside existing 1333 MHz memory.

How can I verify the stick is recognised at the correct speed and voltage after installation?

Open Task Manager or a tool such as CPU-Z and confirm the memory shows 4 GB, DDR3L, 1600 MT/s (running at 1333 MT/s) and 1.35 V with 11-11-11 timings.

Does the package include only the SO-DIMM or are any tools or extra brackets supplied?

The box contains one 4 GB 204-pin SO-DIMM module; no screwdriver, thermal pad or additional hardware is included.
