Purpose and compatibility

This 8 GB DDR3 SO-DIMM is built as a direct memory upgrade for Toshiba Satellite C855D-S5100, C855D-S5357 and C855D-S5105 notebooks. It targets owners of those models who need more system memory for everyday multitasking. Buyers with laptops that require a different pin count, voltage or DDR generation cannot use this module.

DDR3 SO-DIMM limits

The module runs at 1600 MHz with CL11 timing on the 204-pin DDR3 SO-DIMM interface used by the listed Satellite models. That interface tops out at the DDR3 1600 standard, so the stick cannot deliver bandwidth beyond PC3-12800. Systems limited to lower DDR3 speeds will clock the module down automatically.

Capacity and headroom

Each supported notebook accepts two SO-DIMM slots with a maximum of 16 GB total, so this single 8 GB stick leaves room for one more identical module to reach the ceiling. An 8 GB upgrade handles typical office workloads and web browsing comfortably; heavier virtualisation or large media editing will still hit the 16 GB platform limit.

Questions about this item

Should I pick the single 8 GB stick or a 2×4 GB kit for my Satellite C855D-S5100?

The C855D-S5100 has two slots and supports up to 16 GB, so one 8 GB module leaves the second slot free for a matching stick later.

Will the 1600 MHz rating actually run at 1600 MHz inside my laptop?

The module is rated DDR3 1600 (PC3 12800) at 1.5 V with CL11 timing; the laptop’s memory controller will set the final speed, but the stick is built for that frequency.

Does the 204-pin DDR3 SO-DIMM interface limit bandwidth compared to newer standards?

The 204-pin DDR3 SO-DIMM form factor caps transfer rate at the module’s rated 1600 MT/s (PC3 12800); it cannot exceed that DDR3 ceiling.
