System-Specific SODIMM for Toshiba Satellite

This 2 GB DDR3-1066 module is built for the Toshiba Satellite C655-S5054, C655-S5056 and C655-S5068 laptops. It delivers a direct memory upgrade for owners of those models who need to restore or expand system RAM. The stick is unbuffered, non-ECC and runs at the standard 1.5 V for DDR3 SO-DIMMs.

204-pin layout and CL7 timing

The module uses a 204-pin SO-DIMM edge connector that matches the factory memory slots in the compatible Satellites. With a CAS latency of CL7 and 7-7-7 timings, it operates at the rated PC3-8500 speed without requiring voltage changes. No heat spreader is fitted, so the board sits flush in tight notebook bays.

Check slot count and per-slot limit

The supported laptops have two memory sockets and a maximum of 4 GB total, capped at 2 GB per socket. Verify how many slots are free and whether a 2 GB stick fits the per-socket ceiling before ordering. This single module fills one socket and cannot exceed the 2 GB per-slot specification.
