Targeted DDR3 SO-DIMM for Toshiba Satellite

This 4 GB DDR3 SO-DIMM runs at 1333 MHz with CL7 timing and 1.5 V operation. It is built specifically for the Toshiba Satellite C855D-S5320, C855D-S5340 and C855D-S5305 notebooks. The unbuffered, non-ECC module uses major-brand chips in a 2Rx8 configuration. Installation adds a single 204-pin stick to the system.

Upgrade from lower capacity or slower DDR3

Replacing a 2 GB module or a CL9 1333 MHz stick yields more headroom for multitasking and reduces swap-file activity. The jump is worth it when the laptop currently runs with a single channel or when the existing memory operates at a higher latency. Systems already populated with two 4 GB CL7 modules will not benefit from this addition.

Limited by DDR3 platform constraints

The DDR3 interface caps bandwidth at the PC3-10600 rate regardless of faster modules being installed. The laptop’s two sockets support a maximum of 16 GB total, so this 4 GB stick leaves room for one more module. Buyers who need more than 16 GB or who require ECC protection cannot use this memory.

Questions about this item

Will the 204-pin SO-DIMM fit the memory slot in a Toshiba Satellite C855D-S5320?

Yes, the 204-pin DDR3 SO-DIMM matches the slot specification for the listed Toshiba Satellite models.

Does the CL7 timing require any BIOS changes during installation, or is it plug-and-play?

The module runs at 1.5V with standard JEDEC timings, so it installs plug-and-play without BIOS adjustment.

If a memory chip fails years later, can the single 4GB stick be replaced individually?

Yes, the kit contains one 4GB stick, so a single module can be swapped under the manufacturer's lifetime warranty.
