4GB DDR3 SODIMM for Toshiba Satellite

This 4GB DDR3 1600MHz module is built for Toshiba Satellite C55Dt-A5305, C55Dt-A5306 and C55Dt-A5148 notebooks. It suits owners who need a direct replacement or a single-slot capacity increase without configuration changes.

204-pin unbuffered stick with CL11 timing

The module uses a standard 204-pin SO-DIMM edge connector and runs at 1.5V with 11-11-11 latency. No heat spreader is fitted, so it slides into tight SODIMM sockets and leaves clearance for adjacent components in compact chassis.

Upgrade from 2GB or 4GB factory configurations

The supported platforms accept up to 16GB across two sockets, so adding this stick raises total memory when a slot is free. Buyers whose notebooks already populate both sockets with 8GB modules cannot use this kit to increase capacity further.

Questions about this item

What does the PC3-12800 rating on this DDR3 SODIMM mean for real-world bandwidth?

PC3-12800 indicates a peak transfer rate of 12,800 MB/s. The module runs at 1600MHz with CL11 11-11-11 timings at 1.5V, delivering that bandwidth when the platform supports DDR3-1600.

Will the 204-pin stick fit the two SODIMM slots in a Toshiba Satellite C55Dt-A5305?

Yes. The 204-pin DDR3 SO-DIMM form factor matches the two slots in the C55Dt-A5305, C55Dt-A5306 and C55Dt-A5148. The notebook accepts up to 16GB total across both sockets.

Which way round does the key notch go when inserting this unbuffered 2Rx8 module?

Align the off-centre notch on the 204-pin edge connector with the key in the slot, press firmly until the side clips click. The common mistake is stopping before both clips engage fully.
