4GB DDR3 1600MHz SODIMM for Toshiba Satellite

This 4GB DDR3 1600MHz SO-DIMM module is built for Toshiba Satellite C55-C5207S, C55-C5206S and C55-A5390 laptops. It runs at PC3-12800 speed with CL11 latency at 1.5V. The unbuffered, non-ECC stick uses a 204-pin interface and major-brand chips.

Suits owners of the listed Toshiba models needing

Buyers whose laptops are not in the compatibility list should verify fitment before ordering. Systems requiring ECC or registered memory cannot use this module. Laptops limited to DDR3L 1.35V operation may not be compatible with the 1.5V specification.

The 204-pin DDR3 SO-DIMM form factor decides fitment

Only notebooks accepting 204-pin DDR3 SO-DIMMs at 1600MHz can install this stick. The 2Rx8 rank and 11-11-11 timing are fixed by the module design. Match these exact specifications to your system manual for guaranteed operation.

Questions about this item

Should I pick this 4 GB module or a larger capacity for my Satellite C55-C5207S?

The laptop accepts up to 16 GB across two slots, so this 4 GB stick works alone or paired with another for 8 GB or 16 GB total.

What does the DDR3-1600 (PC3-12800) rating mean once installed?

The module runs at 1600 MHz with CL11 timing at 1.5 V, delivering the standard DDR3-1600 data rate your chipset expects.

Does the 204-pin SODIMM interface limit anything in my C55-A5390?

It fits the 204-pin DDR3 slots on the C55-A5390; the board caps speed at DDR3-1600, so the module operates at its rated frequency.
