  • 204-pin SO-DIMM fits compatible laptop slots
  • Dual 2 GB modules provide 4 GB total capacity
  • DDR3-1600 speed rated at PC3-12800
  • Two-module kit enables dual-channel operation
  • Designed for Toshiba Satellite C55-A and C55-A5308 notebooks

DDR3 SO-DIMM 1600 MHz kit

This kit contains two Samsung DDR3 SO-DIMM modules, each rated at 2 GB for a total of 4 GB. They operate at PC3-12800 (DDR3-1600) and use the standard 204-pin layout. The memory is designed for DDR3 SO-DIMM slots in notebook computers.

Suited for DDR3 laptop upgrades

It fits owners of Toshiba Satellite C55-A C55-A5308 notebooks or other laptops that accept DDR3 SO-DIMMs at this speed and capacity. Systems that require a different form factor, pin count or bus speed cannot use these modules. Buyers needing more than 4 GB total should look for higher-capacity kits.

204-pin DDR3 SO-DIMM interface

The 204-pin SO-DIMM connector is the single specification that determines compatibility. If the motherboard slot matches this pin count and supports DDR3-1600, the kit will install and run at the rated speed.

Questions about this item

Will the 204-pin SO-DIMM modules fit the memory slots in a Toshiba Satellite C55-A5308?

Yes, these are 204-pin DDR3 SO-DIMM modules, which is the standard form factor used in the Satellite C55-A series notebooks.

What is the correct way to seat both 2 GB sticks so the laptop recognises the full 4 GB?

Insert each module at an angle until the gold contacts are hidden, then press down firmly until both side clips click into place; the common mistake is stopping before the clips engage.

How can I verify the memory is running at the rated 1600 MHz after installation?

Open Task Manager or a system-information tool and check the reported memory speed; it should show 1600 MHz (PC3-12800) if the modules are operating at their specified bus speed.
