  • Two 8 GB sticks included to fill both memory sockets

Targeted DDR3 Upgrade Kit

This 16 GB kit contains two 8 GB DDR3 SO-DIMM modules rated at 1333 MHz with CL9 timings. It is built specifically for the Toshiba Satellite C855D-S5320, C855D-S5340 and C855D-S5305 notebooks.

Low-Voltage Unbuffered Operation

The modules run at the standard DDR3 voltage of 1.5 V and use unbuffered, non-ECC chips in a 2Rx8 configuration. No heat spreaders are fitted, so the sticks rely on the laptop’s existing airflow.

Direct Slot Replacement

The 204-pin form factor matches the factory memory slots exactly, requiring no adapters or BIOS changes. The dual-channel pair fills both sockets to reach the 16 GB maximum supported by these models. Buyers needing ECC, registered DIMMs or a different DDR generation must choose another product.

Questions about this item

How do I install the 204-pin SODIMM modules in my Toshiba Satellite C855D-S5320, and what step do people often miss?

Power off the laptop, remove the battery, open the memory compartment, align the notch on each 204-pin DDR3 module with the slot key, press firmly until the side clips click, then reassemble. The step many miss is pressing hard enough for both clips to engage fully.

Will the 1.5 V DDR3 1333 MHz kit need any maintenance or replacement during the laptop's life?

No routine maintenance is required for unbuffered DDR3 SODIMMs. If a module fails, the limited lifetime warranty from Computer Memory Solutions covers replacement; otherwise the memory lasts as long as the system.

What limit appears first when the 2Rx8 CL9 modules run sustained workloads in the Satellite C855D-S5340?

The memory controller in the C855D series caps bandwidth at DDR3-1333, so sustained throughput is limited by that bus speed rather than the CL9 timing or 2Rx8 organisation.
