Matched kit for Satellite P855 series

This kit delivers 16 GB of DDR3L memory in two 8 GB SO-DIMMs built specifically for Toshiba Satellite P855-S5200, P855-S5312 and P855-S5321 notebooks. It targets owners who want the maximum factory-supported capacity without guessing at compatibility.

Slot-ready upgrade for two sockets

Each module uses the 204-pin SO-DIMM form factor and runs at 1.35 V, matching the voltage the platform expects. The pair fills both available slots, removing the need to mix old and new sticks and freeing the installer from checking individual module densities.

Steady throughput at CL11 1600 MHz

Rated at DDR3-1600 with 11-11-11 timings, the modules maintain their rated speed during extended workloads rather than throttling after a brief burst. The unbuffered, non-ECC design keeps latency predictable for everyday multitasking and sustained background tasks.

Questions about this item

Will the 1.35 V DDR3L voltage limit cause instability under sustained load?

The kit runs at the standard 1.35 V DDR3L voltage with CL11 11-11-11 timings, matching the Satellite P855-S5200 memory controller specification for stable continuous operation.

How much heat do the 2Rx8 modules produce during all-day use without a heat spreader?

Unbuffered 2Rx8 DDR3L SODIMMs at 1.35 V generate modest heat; the laptop's internal airflow across the 204-pin slots is sufficient for continuous duty.

Does the Toshiba Satellite P855-S5200 need a BIOS update before installing this 16 GB kit?

The P855-S5200, P855-S5312 and P855-S5321 all support a maximum of 16 GB across two sockets, so the 2 x 8 GB kit fits the factory configuration without a BIOS change.
