4 GB DDR3 1333 SO-DIMM for Toshiba Satellite C855

This 4 GB DDR3 1333 MHz SO-DIMM is built for Toshiba Satellite C855-S5356, C855-S5358 and C855D-S5106 laptops. It suits owners who need a single 204-pin module to restore or expand system memory in those specific models. The unbuffered, non-ECC design matches the original specification for everyday computing tasks.

DDR3 1333 speed caps transfer rate at PC3 10600

The module runs at DDR3 1333 (PC3 10600) with CL7 7-7-7 timing at 1.5 V. This interface ceiling limits peak bandwidth regardless of the processor or chipset installed. Systems that officially support DDR3 1600 will downclock this stick to 1333 MHz, so the full 1600 MT/s potential cannot be reached with this part.

Check your laptop has a free SO-DIMM slot

The supported models accept a maximum of 16 GB across two sockets. Verify that at least one 204-pin slot is vacant and that adding this 4 GB stick keeps the total within the 16 GB ceiling. Buyers needing more than 16 GB total or a second module for dual-channel must look elsewhere.

Questions about this item

Should I pick the 4 GB stick or aim for the 16 GB maximum the laptop supports?

The module is a single 4 GB stick; the Satellite C855 series accepts two slots up to 16 GB total, so adding a second identical module later will reach the limit.

The box says 1333 MHz but the highlights mention 1600 MHz — what speed will I actually see?

The stick is rated DDR3-1333 (PC3-10600); if the laptop’s memory controller only runs at 1333 MHz, the module will operate at that speed.

Is this a standard 204-pin DDR3 SO-DIMM that fits any laptop slot?

Yes, it uses the 204-pin DDR3 SO-DIMM form factor, which is the standard interface for DDR3 laptop memory and fits the compatible Satellite models listed.
