Compatible DDR3L SODIMM for Toshiba Satellite

This 4 GB DDR3L 1600 MHz module is built for Toshiba Satellite C55D-B5206, C55D-B5212 and C55D-B5214 notebooks. It uses a 204-pin SO-DIMM form factor with CL11 11-11-11 timings and 1.35 V operation. The unbuffered, non-ECC design fits the single available slot for a straightforward memory upgrade.

Low-voltage operation keeps thermals steady

Running at 1.35 V reduces power draw compared to standard DDR3, helping the laptop maintain cooler temperatures during everyday workloads. The module has no heat spreader, relying on the chassis airflow already present in the compatible models. Silent solid-state construction adds no audible noise to the system.

Replaces or adds to factory 4 GB configurations

The supported notebooks ship with 4 GB in one slot and accept up to 16 GB across two sockets. Adding this stick doubles capacity to 8 GB, while a second identical module completes the 16 GB maximum. The upgrade is worthwhile when multitasking or browser tabs exceed the original memory ceiling.

Questions about this item

How do I install the 204-pin DDR3L SODIMM in my Toshiba Satellite C55D-B5206, and which step do people often miss?

Power off the laptop, remove the battery if accessible, open the memory compartment, align the notch on the module with the slot key, insert at an angle then press down until both side clips click. The step people miss is fully seating the module so both clips engage.

What maintenance or replacement will this 4GB DDR3L 1600 module need over time?

No routine maintenance is required. If a memory error appears, reseat the stick to clear oxidised contacts. Replace the module only if diagnostics confirm a failure; Computer Memory Solutions provides a limited lifetime warranty against manufacturing defects.

What limit appears first when this CL11 1.35V SODIMM runs sustained workloads in a Satellite C55D-B5214?

The practical limit is the laptop's two-slot, 16GB maximum. With one 4GB stick installed you can add a second module for 8GB total, but the chipset and BIOS cap usable memory at 16GB, so capacity is the first constraint.
