Targeted DDR3 Upgrade

This 4 GB SODIMM is built for Toshiba Satellite C855-S5346, C855-S5347 and C855-S5348 notebooks. It installs in a 204-pin DDR3 slot and raises the system memory toward the 8 GB maximum supported by those models. The module is unbuffered, non-ECC and uses a 2Rx8 rank configuration.

Low Voltage Operation

Running at 1.5 V, the memory draws minimal power and produces negligible heat inside the compact chassis. With no heat spreader and no active cooling required, it adds no audible noise to the laptop. The CL7 timing at 1333 MHz keeps latency low during everyday workloads.

From 2 GB or 4 GB Single Channel

Replacing a 2 GB stick or adding this module to a single occupied slot enables dual-channel bandwidth on the two-socket platform. The jump is worthwhile when the current configuration leaves headroom below the 8 GB limit and the workload benefits from the extra capacity and matched pair throughput.

Questions about this item

How do I install the 204-pin SODIMM into my Toshiba Satellite C855-S5346, and which step is often missed?

Power off the laptop, remove the battery, open the memory hatch, align the notch on the 204-pin DDR3 SODIMM with the slot key, press firmly until the side clips click, then replace the hatch and battery before booting.

What maintenance or replacement will this 4GB DDR3-1333 CL7 module need later?

No scheduled maintenance is required; the module has no heat spreader and uses standard 1.5V DDR3 chips, so replacement is only needed if a memory test reports errors or you upgrade to the 8GB maximum supported by the C855 series.

What limit appears first when this CL7 1.5V SODIMM runs sustained workloads?

The 1333 MHz DDR3 speed and CL7 timing set the bandwidth ceiling, so memory throughput saturates before the 1.5V voltage or unbuffered 2Rx8 organisation becomes a bottleneck.
