Targeted notebook upgrade

This 4GB DDR3L SODIMM is built for the Toshiba Satellite C55D-B5244, C55D-B5308 and C55D-B5310 models. It suits owners who need a single module to fill one slot or replace a failed stick. The CL11 timing and 1.35V voltage match the original specification. Buyers who want more storage or a different form factor will not be served by this part.

Slot-ready installation

The 204-pin unbuffered design drops straight into the notebook’s memory socket without adapters or configuration changes. One rank of 1Rx8 chips keeps the electrical load light for the integrated controller. The module frees the second slot for a future addition up to the platform limit. Systems that require ECC or registered memory cannot use this stick.

Steady low-voltage operation

DDR3L 1600 at 1.35V runs cooler than standard 1.5V DDR3 during extended workloads. The major-brand chipset and 11-11-11 timing deliver consistent throughput for everyday multitasking. No heat spreader is fitted, so airflow in the chassis handles thermal dissipation. Sustained performance stays within JEDEC limits for the rated speed.

Questions about this item

Will the CL11 latency limit throughput during sustained workloads?

CL11 timing at 1600 MHz is the rated specification; sustained throughput follows that latency figure.

Does the 1.35 V DDR3L module run cooler or quieter than standard-voltage DDR3 during all-day use?

At 1.35 V the module draws less power than 1.5 V DDR3, reducing heat output in the laptop chassis.

Must the Toshiba Satellite already have a free 204-pin SODIMM slot for this upgrade?

Yes, the notebook needs an available 204-pin DDR3 SODIMM socket; the listed models provide two slots supporting up to 16 GB total.
