SKU CH-0NBG-XT0JX

DDR3 laptop memory kit totalling 4 GB across two 204-pin SO-DIMM modules rated at PC3-12800, validated for specific Toshiba C855 series models

  • 4GB total capacity for smoother multitasking
  • Dual 2GB modules enable dual-channel bandwidth

  • 204-pin SO-DIMM fits laptop memory slots
  • Engineered for Toshiba C855 series laptops

Compatible Laptop Upgrade

This kit provides 4 GB of DDR3 memory in two 2 GB SO-DIMM modules for specific Toshiba Satellite models. It targets owners of the C855D-S5303, C855D-S5315 and C855-S5206 who need a straightforward capacity increase. The 204-pin design matches the laptop slots exactly.

Replaces Lower Capacity DDR3

The kit upgrades systems that originally shipped with less memory or slower DDR3 speeds. Moving to the full 4 GB at PC3-12800 (DDR3-1600) is worthwhile when the existing configuration limits multitasking or causes frequent disk swapping. It restores responsive operation for everyday workloads.

Suits Listed Toshiba Models Only

This memory suits users who have confirmed their laptop matches the three supported model numbers. Buyers with different Toshiba series or other brands should look elsewhere because the SO-DIMM pinout and timing are validated only for the C855D-S5303, C855D-S5315 and C855-S5206.

Questions about this item

Will the 204-pin SO-DIMM modules fit the memory slots in a Toshiba C855D-S5303?

Yes, the 204-pin SO-DIMM form factor matches the DDR3 slots used in the Toshiba C855D-S5303, C855D-S5315 and C855-S5206 models.

What is the correct way to seat both 2 GB modules so the laptop runs at PC3-12800 speed?

Insert each module at an angle into the slot, then press down firmly until the side clips click; the step often missed is not pressing far enough for both clips to engage.

When should I consider replacing these DDR3 modules?

Replace them if the laptop fails to boot, shows memory errors in diagnostics, or becomes unstable after the modules have been reseated and the slots cleaned.
