8 GB DDR3 SO-DIMM for Toshiba Satellite C855D

This 8 GB DDR3 1333 SO-DIMM is built for Toshiba Satellite C855D-S5103, C855D-S5202 and C855D-S5203 notebooks. It delivers 8 GB of unbuffered, non-ECC memory in a single 204-pin module running at 1.5 V. The CL9 9-9-9 timing matches the platform spec. Buyers needing ECC or registered DIMMs should look elsewhere.

Upgrade from 4 GB or 8 GB factory configurations

The supported laptops ship with two slots and a 16 GB maximum. Adding this module to an empty slot or replacing a 4 GB stick raises total capacity toward that ceiling. The jump is worthwhile when multitasking pushes the original amount into paging. Systems already at 16 GB gain no further benefit from this part.

Straightforward slot installation

The SO-DIMM inserts into the 204-pin socket at a shallow angle until the retention clips engage. No heat spreader means low profile clearance inside the service bay. The most common issue is seating the module fully; a partial insert causes a no-post condition. Verify the notch alignment before applying pressure.

Questions about this item

Will this 204-pin DDR3 SO-DIMM fit the memory slot on my Toshiba Satellite C855D-S5103?

Yes, the module is built to the 204-pin DDR3 SO-DIMM form factor used by the Satellite C855D-S5103, C855D-S5202 and C855D-S5203.

What is the correct way to seat this 8 GB DDR3-1333 stick so it locks in place?

Align the notch on the module with the key in the slot, push in evenly until the contacts are fully inserted, then press down until both side clips snap into the notches.

Does this CL9 1.5 V module need any firmware updates or periodic replacement after installation?

No firmware updates are required; the memory is a passive component and should run for the life of the laptop unless a fault develops.
