System-Specific 4GB DDR3 SO-DIMM

This 4GB DDR3 1333 MHz SO-DIMM module is built for Toshiba Satellite C655-S5549 and C655D-S5518 notebooks. It runs at 1.5V with CL7 timing and uses an unbuffered, non-ECC design. The 204-pin form factor fits the factory memory slots in these models.

Suits owners of the listed Satellites adding

Buyers with other laptop models or desktop systems should look elsewhere because the module is validated only for the named Toshiba part numbers. Systems that require ECC, registered memory or a different DDR generation will not accept this stick.

Simple slot insertion with no tools

Align the notch on the 204-pin edge connector, press firmly until the side clips click, then reboot. The most common issue is the module not seating fully, which leaves the system showing the original memory total.

Questions about this item

Does the laptop need a free 204-pin SO-DIMM slot to install this 4GB DDR3 1333 module?

Yes, the Toshiba Satellite C655-S5549 and C655D-S5518 each have two 204-pin slots, so one must be empty for this stick.

Will this CL7 1333 MHz stick run correctly alongside an existing CL9 1333 MHz module in the second slot?

The system will operate both modules at the slower CL9 timing, so the upgrade works without manual changes.

How can I confirm the new module is detected at 1333 MHz after installation?

Open Task Manager Performance tab or run CPU-Z; the memory section should show 4 GB running at 1333 MHz.
