System-specific DDR3L upgrade

This 8 GB SODIMM is built for Toshiba Satellite C55-A5311, C55-A5309 and C55-A5302 notebooks. It delivers a single 8 GB module running at 1600 MHz with CL11 timing. The 1.35 V DDR3L voltage matches the factory specification for these models. Buyers needing more than 16 GB total capacity or a second module for dual-channel should look elsewhere.

Low-voltage thermal profile

Operating at 1.35 V reduces heat output compared with standard 1.5 V DDR3 modules. The unbuffered, non-ECC design draws minimal power during typical workloads. No heat spreader is fitted, so the module relies on the notebook’s existing cooling. Acoustic impact is negligible because the memory adds no moving parts.

Single-stick package contents

The box contains one 204-pin SODIMM and nothing else. No software, drivers or installation tools are bundled. The limited lifetime warranty against manufacturing defects applies when purchased directly from Computer Memory Solutions. Compatibility is guaranteed for the three listed Satellite models.

Questions about this item

How do I install the 204-pin SODIMM into my Satellite C55-A5311, and which step is often missed?

Power off, unplug, remove the battery, open the memory cover, insert the module at a 30-degree angle until the gold pins disappear, then press down until both side clips click — many forget to reseat the battery before booting.

What maintenance or replacement will this 8GB DDR3L 1600MHz module need over time?

No scheduled maintenance is required; if a fault appears, the limited lifetime warranty from Computer Memory Solutions covers exchange or repair for manufacturing defects.

What limit appears first when this CL11 1.35V memory runs sustained workloads on the dual-slot Satellite C55-A5311?

The platform caps total memory at 16GB across the two sockets, so adding a second 8GB stick reaches the ceiling before bandwidth or thermal limits become an issue.
