Compatible Toshiba Satellite upgrade

This 16 GB kit contains two 8 GB SODIMM modules built for Toshiba Satellite C850 and C855 series notebooks. The memory runs at DDR3L 1600 with CL11 timing and operates at 1.35 V. It is designed as a direct replacement for the factory-installed modules in the listed models.

System-specific fit

The kit is validated for Satellite C850-St4Nx1, C855-S5107 and C855-S5134 laptops that accept up to 16 GB across two sockets. Owners of other Toshiba models or different brands should verify their exact part-number requirements before purchasing. Systems needing ECC or registered DIMMs cannot use this unbuffered non-ECC kit.

DDR3L 1600 voltage

Each module is a 204-pin DDR3L device rated for 1.35 V operation at 1600 MHz. If the target notebook requires 1.5 V DDR3 or a different memory generation, the modules will not function correctly.

Questions about this item

How can I verify the memory is running at 1600 MHz with CL11 timing after installing it in my Satellite C855-S5107?

Open Task Manager or BIOS and confirm the speed reads 1600 MHz and the CAS latency shows 11-11-11.

The kit includes two 8 GB modules; do I need any extra brackets or tools for the Satellite C850-ST4NX1?

No extra parts are required; the package contains both 204-pin SODIMM sticks and they fit directly into the two slots.

My Satellite C855-S5134 supports 16 GB maximum across two sockets — is this 2 x 8 GB kit the correct one to reach that limit?

Yes, the kit provides exactly 16 GB in two modules, matching the laptop's two-slot, 16 GB maximum configuration.
