Compatible 4GB DDR3 SODIMM

This 4GB DDR3 1333MHz SODIMM module is built specifically for Toshiba Satellite C55-A5245, C55-A5243 and C55-A5298 notebooks. It uses a 204-pin unbuffered non-ECC design with CL7 timing at 1.5V. The single stick provides a direct memory upgrade for those compatible systems.

Verify slot count and maximum capacity

Before ordering, confirm your laptop has an available SODIMM slot and check the current memory configuration. The supported models accept a maximum of 16GB across two sockets, so a 4GB module fits within that limit. Ensure the existing memory runs at 1.5V to match this module's voltage requirement.

Fits two-slot DDR3 platforms

This module installs into one of two DDR3 SODIMM sockets in the compatible Toshiba Satellite notebooks. Adding it leaves the second slot free for a future upgrade up to the 16GB system maximum. The 204-pin form factor matches the socket keying for DDR3 platforms without requiring a heat spreader or registered buffering.

Questions about this item

Does the box contain anything other than the single 204-pin SODIMM module?

The package includes only one 4 GB DDR3 1333 MHz SODIMM stick. No cables, brackets or tools are supplied.

My Satellite C55-A5245 has two slots and supports 16 GB maximum. Should I buy one 4 GB module or two?

Installing two 4 GB modules fills both slots for 8 GB total and enables dual-channel operation, which is faster than a single stick.

The listing mentions both 1333 MHz and 1600 MHz speeds. Which speed will the memory actually run at in my C55-A5243?

The module is rated for 1333 MHz (PC3-10600). If the notebook's memory controller only supports 1333 MHz, the stick will run at that speed.
