16GB DDR3 SO-DIMM kit for Toshiba Satellite C55-A

This 16GB kit contains two 8GB DDR3 SO-DIMM modules rated at 1600MHz with CL11 timings. It is built for Toshiba Satellite C55-A5285, C55-A5286 and C55-A5310 notebooks that accept 204-pin unbuffered memory. The modules operate at 1.5V and use major-brand chipsets in a 2Rx8 configuration.

Fits two SO-DIMM slots

Each laptop listed has two memory sockets and a 16GB ceiling, so this pair fills every slot and delivers the full capacity the board allows. No heat spreader is fitted, keeping the modules low-profile for tight chassis clearance. The non-ECC, unbuffered design matches the factory specification without requiring BIOS changes.

Steady throughput at standard voltage and latency

Running at the JEDEC-standard 1.5V and 11-11-11 timings, the kit maintains consistent bandwidth during extended workloads such as large dataset processing or multi-tab browsing. The absence of overclocked profiles means thermal output stays predictable, avoiding throttling that can appear with higher-voltage alternatives during long sessions.
