Targeted laptop upgrade

This 4GB DDR3L SODIMM is built for the Toshiba Satellite C50-A-110, C50-A-12K and C50-A-15E. It installs in a 204-pin slot and runs at 1.35V to match the platform voltage. The single stick adds memory capacity without requiring a matched pair. Buyers with other laptop models should verify their slot type and voltage before ordering.

Sustained operation profile

The module operates at 1600MHz with CL11 timing of 11-11-11 and a 2Rx8 rank structure. Unbuffered design and the absence of a heat spreader keep the form factor thin for tight chassis clearance. Voltage remains fixed at 1.35V during extended workloads. Major-brand chipsets provide stable signal integrity over long sessions.

Capacity fit decision

The kit contains one 4GB stick and the supported laptops accept a maximum of 16GB across two sockets. This capacity suits a single-slot top-up or a budget dual-channel pair. Systems already populated with two modules cannot accept this stick without removing existing memory.

Questions about this item

How much heat and power does this 1.35V DDR3L SODIMM produce when running all day?

The module operates at 1.35 volts, which is lower than standard DDR3, so it generates less heat and draws less power during continuous use.

What must my Toshiba Satellite C50-A series laptop already have for this 204-pin SODIMM to work?

Your laptop needs a free 204-pin DDR3L SO-DIMM slot and a memory controller that supports 1600 MHz CL11 unbuffered non-ECC modules.

Will this 2Rx8 CL11 stick run alongside an older 1Rx8 DDR3L module in the second socket?

Yes, the system will run both sticks at the slower module's speed and timings, so the older 1Rx8 module sets the pace for the pair.
