Laptop DDR3 SO-DIMM module

This Samsung module provides four gigabytes of DDR3 memory in a 204-pin SO-DIMM form factor. It is built for laptop systems that accept DDR3 SDRAM. The single stick delivers a total capacity of 4GB for straightforward upgrades or replacements.

PC3-12800 bus speed ceiling

The module operates at a bus speed of PC3-12800, which corresponds to DDR3-1600. This rating sets the maximum data rate the stick can sustain when installed in a compatible slot. Systems limited to lower DDR3 speeds will still run the memory, but only at the slower rate supported by the platform.

Toshiba L855 series compatibility

The supplier identifies this part for Toshiba L855-S5155, L855-S5156, L855-S5157 and L855-S5189 models. Buyers with other laptops must verify that their machine accepts 204-pin DDR3 SO-DIMMs at the PC3-12800 specification before purchasing.

Questions about this item

Should I pick the single 4 GB module or look for a different capacity for my Toshiba L855?

This listing supplies one 4 GB SO-DIMM; add a second identical module if your laptop has two slots and you want 8 GB total.

What does the DDR3-1600 rating deliver in everyday use?

The module runs at 1600 MT/s, giving the bandwidth the L855 series chipset expects for normal multitasking and media playback.

How does the PC3-12800 designation limit performance in this laptop?

PC3-12800 is the JEDEC label for DDR3-1600; the memory controller in the L855 will not run it faster than that standard speed.
