Targeted system upgrade

This 16 GB DDR4 SODIMM is built for Toshiba Tecra A40-D, A50-E and C50-D laptops. It delivers a single-module capacity increase without requiring matched pairs or dual-channel planning.

Fits two-slot layout

The module uses the standard 260-pin SO-DIMM form factor and runs at 1.2 V unbuffered non-ECC. Two sockets are available in the target systems, so this stick leaves the second slot open for a future 16 GB addition up to the 32 GB platform maximum.

Low-voltage operation

At 1.2 V the module draws minimal power and generates little heat inside a thin-and-light chassis. No heat spreader is fitted, relying on the laptop’s existing airflow for silent, stable operation at 2400 MHz CL17.

Questions about this item

Does the CL17 timing at 2400 MHz limit throughput when the laptop runs memory-heavy tasks for long periods?

The module runs at DDR4 2400 with CL17 17-17-17 timings, so sustained bandwidth is capped by that speed and latency.

Will the stick run hot or draw extra power during all-day use?

It operates at the standard 1.2 V without a heat spreader, so power draw and heat stay at normal DDR4 SO-DIMM levels.

Which laptops must I already own for this 260-pin SODIMM to work?

It is validated for Toshiba Tecra A40-D, A50-E and C50-D models with part numbers PS483A-063013, PS599A-00L00L and PT593C-00P009.
