System-specific DDR3L SODIMM for Toshiba Satellite

This 4GB DDR3L SODIMM runs at 1600MHz with CL11 timing at 1.35V. It is built as a single unbuffered 2Rx8 module using 204 pins. The kit is validated for Satellite C855D-S5209, C855D-S5238 and C855-S5108 notebooks.

DDR3L voltage and speed ceiling

DDR3L modules operate at 1.35V rather than the 1.5V of standard DDR3, so they only fit platforms that support the lower voltage. The PC3L-12800 rating caps the data rate at 1600MHz; faster DDR3 speeds are not reachable with this stick. Systems limited to 1.5V will not recognise the module.

Replaces a single factory SODIMM

Swapping the original stick for this 4GB unit restores the memory capacity the laptop shipped with. The upgrade is worthwhile when the existing module has failed or when the sole slot is empty. It does not add capacity beyond 4GB because only one module is included.

Questions about this item

Should I choose the single 4 GB stick or a 2×4 GB kit for my Toshiba Satellite C855D-S5209?

The module is sold as a single 4 GB stick. If your laptop has two slots and you want 8 GB total, add a second identical module; otherwise this one stick provides 4 GB.

What does the PC3L 12800 rating mean once the module is installed?

It confirms the memory runs at 1600 MHz with CL11 timings at 1.35 V, delivering up to 12 800 MB/s bandwidth in the Satellite C855D-S5209, C855D-S5238 or C855-S5108.

Will the 204-pin DDR3L SO-DIMM work in a standard DDR3 slot?

Yes, the 204-pin DDR3L SO-DIMM fits the DDR3 SO-DIMM slots in the listed Toshiba Satellite models and operates at the standard 1.35 V.
