Compatibility & Capacity

This 4 GB DDR3 SO-DIMM is built specifically for Toshiba Satellite C855D-S5303, C855D-S5354 and C855D-S5339 laptops. It uses a 204-pin form factor and runs at 1.5 V with CL7 7-7-7 timing. The module is unbuffered, non-ECC and organised as 2Rx8 with major-brand chips. One stick is supplied in the package.

Ideal & Unsuitable Buyers

Owners of the listed Satellite models who need a single 4 GB upgrade will find guaranteed compatibility. Buyers who want more storage, a different memory generation, or a kit with multiple sticks should look at other products. The part is not intended for desktops, servers or any system outside the three named models.

Decisive Specification

The 204-pin DDR3 SO-DIMM interface at DDR3 1333 (PC3-10600) with CL7 latency is the single detail that determines fit. If your laptop requires this exact pin count, voltage and speed grade, the module will work; otherwise it will not seat or function.

Questions about this item

Is this 4 GB module the right choice for a single-slot upgrade or should I buy two for dual-channel?

The module is sold as a single 4 GB stick; the compatible Satellite C855D models have two sockets and support up to 16 GB total, so adding a second identical stick enables dual-channel operation.

The listing shows both PC3-10600 and DDR3-12800 — which speed will I actually see in my Satellite C855D?

The module is rated DDR3 1333 (PC3-10600) with CL7 timing; the higher 1600 MHz figure is a manufacturer highlight, but the laptop's memory controller will run it at 1333 MHz.

Will the 204-pin DDR3 SO-DIMM fit the memory slot in my C855D-S5303?

Yes — the Satellite C855D series uses 204-pin DDR3 SO-DIMM sockets, and this stick matches that exact form factor, voltage (1.5 V) and unbuffered, non-ECC specification.
