Compatible Toshiba Satellite upgrade

This 4 GB DDR3L SODIMM module is built for the Toshiba Satellite C855D-S5307, C855-S5190 and C855-S5137 notebooks. It adds memory capacity to systems that currently have a single slot populated or need a replacement stick. Buyers whose laptops are not on this validated list should verify compatibility before ordering.

Low-voltage operation

The module runs at 1.35 V, which is the standard DDR3L voltage and reduces power draw compared with 1.5 V DDR3 parts. Lower voltage also means less heat generated inside the chassis during normal workloads. No active cooling is required because the stick has no heat spreader.

Single-stick kit

The package contains one 204-pin SODIMM, so a second module must be purchased separately to reach the platform maximum of 16 GB across two sockets. There is no bundled software or diagnostic utility included with the memory. Product appearance may differ from the reference photograph.

Questions about this item

How do I install this 204-pin SODIMM in my Satellite C855-S5190 and what step is often missed?

Power off the laptop, remove the battery, open the memory door, align the notch on the 204-pin module with the slot key, press firmly until both side clips click, then refit the battery before booting.

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

No scheduled maintenance is required; if errors appear, run a memory test and replace the stick if faults are confirmed.

What limit appears first during sustained workloads on this CL11 1.35V kit?

The 4GB capacity and CL11 latency at 1600 MHz become the bottleneck before thermal or voltage limits are reached.
