System-Specific SODIMM Kit for Toshiba Satellite

This 8GB kit contains two 4GB DDR3-1333 SO-DIMM modules built to the PC3-10600 standard. It is designed as a direct memory upgrade for the Toshiba Satellite C655-S5542, C655-S5540 and C655D-S5540 notebooks.

Suitable for owners of the listed Satellite models

The kit fills both memory sockets to reach the 8GB limit stated for these systems. It is not for users whose laptops require ECC or registered memory, nor for anyone whose device uses a different pin count or voltage than the 204-pin 1.5V specification.

CL7 latency at DDR3-1333 speed

The modules run at CAS latency 7 with 7-7-7 timing, which is tighter than the more common CL9 alternative at this frequency. This timing profile determines whether the memory will operate at the rated speed without stability issues on the supported chipset.

Questions about this item

Will the 204-pin DDR3 SO-DIMM modules fit the two memory slots in a Toshiba Satellite C655-S5542?

Yes, the kit is built for the C655-S5542, C655-S5540 and C655D-S5540, each of which has two 204-pin SO-DIMM sockets and a maximum of 8 GB.

What is the correct way to seat the 204-pin DDR3 SO-DIMM sticks, and what step do people often miss?

Align the notch on the module with the key in the slot, insert at an angle, then press down evenly until both side clips snap into the notches; the step often missed is checking that both clips are fully locked.

When should the 2Rx8 DDR3-1333 CL7 modules be replaced or serviced?

The modules have no moving parts and no heat spreader, so no scheduled maintenance is required; replace only if memory diagnostics report errors or the system fails to boot with them installed.
