Capacity and Compatibility

This kit provides 4 GB of total memory using two 2 GB DDR3 1066 SO-DIMM modules. It is built for the Toshiba Satellite C655-S50521 and PSC08U-03C01L notebooks. The 204-pin form factor matches the sockets in those specific models.

Kit Contents and Operation

The package contains two matched sticks so the system can run in dual-channel mode when both slots are populated. CL7 timing at 1.5 V lets the memory operate at the notebook's native speed without manual configuration. No heat spreader is fitted, keeping the profile low for tight chassis clearance.

Build and Installation

Unbuffered, non-ECC construction with major-brand chips follows the standard JEDEC layout for reliable seat-and-click insertion. The 2 Rx8 organisation is transparent to the platform and requires no BIOS adjustment. Buyers needing more than 4 GB or a different DDR generation cannot use this kit.

Domande su questo articolo

Will the 2Rx8 204-pin SODIMM modules need any firmware updates or reconfiguration after installation?

No firmware updates are required; the unbuffered non-ECC sticks install directly into the compatible Toshiba Satellite C655-S50521 and are recognised by the system BIOS automatically.

What is the first limit reached when the 1066 MHz CL7 memory runs continuously at full load?

The CL7 timing at 1.5 V sets the latency boundary; sustained throughput is capped by the DDR3 1066 data rate rather than thermal or power headroom.

How much heat and power do the two 2 GB sticks produce during all-day operation?

Each module runs at the standard DDR3 1.5 V without a heat spreader, so total power draw stays low and the sticks remain cool under continuous use.
