4GB DDR3 SODIMM for Toshiba Satellite

This 4GB DDR3 1333MHz SODIMM module is built for Toshiba Satellite C55-A5242 C55D-A5240Nr C55D-A5240 laptops. It uses a 204-pin unbuffered non-ECC design with CL7 timing and 1.5V operation. The single stick upgrades one of two available slots in these systems.

Suits owners of listed Toshiba models needing

Buyers whose laptops are not in the compatibility list should verify their exact model before ordering. Systems already populated with two modules have no free slot for this upgrade.

CL7 DDR3 1333MHz speed rating

The module runs at DDR3 1333 (PC3 10600) with 7-7-7 CAS latency. This timing decides whether the memory matches the original specification for stable operation in the target laptops.

Questions about this item

What slot type must my Toshiba Satellite C55-A5242 have for this 204-Pin DDR3 SO-DIMM to fit?

The notebook must provide a 204-pin DDR3 SO-DIMM socket; the compatible models listed each have two such sockets.

If I keep the original module in the second socket, will this 1333 MHz stick run at its rated speed?

The memory controller will run both modules at the lowest common speed, so the original module must also support 1333 MHz for this stick to operate at 1333 MHz.

How can I confirm the BIOS recognises the full 4 GB after installation?

Open the BIOS setup or Task Manager and verify the installed memory shows 4 GB (or 8 GB if both sockets are populated).
