System-Specific DDR3 Kit for Toshiba Satellite C655

This 8 GB kit contains two 4 GB SO-DIMM modules built for the Toshiba Satellite C655-S5211, C655-S5221 and C655-S5231. It uses 204-pin DDR3 technology at 1333 MHz with CL9 timing and 1.5 V operation. The unbuffered, non-ECC design matches the factory memory specification for these notebooks.

8 GB Capacity and DDR3 Headroom

The paired modules fill both memory sockets and reach the 8 GB maximum the platform supports. Each stick is a 1Rx8 rank using 256x8 chips, delivering 16 GB of total addressable space per module. Everyday multitasking, web browsing and office applications run within this limit, while memory-intensive workloads such as virtualisation or large media editing will exhaust the available capacity.

DDR3 1333 MHz Interface Limits

The PC3-10600 interface caps bandwidth at the DDR3 1333 MT/s data rate with 9-9-9 timings. Latency-sensitive tasks benefit from the low CAS figure, yet the bus cannot scale beyond this speed grade. Systems requiring higher throughput or newer memory standards must use a different platform, as the socket and chipset are fixed to this generation.

Questions about this item

Will the 1333 MHz CL9 modules run correctly alongside any existing 1333 MHz DDR3 sticks in my Toshiba Satellite C655?

Yes, matching speed and latency lets the kit operate at its rated 1333 MHz CL9 without downclocking.

How can I confirm the 8 GB kit is detected at 1333 MHz after installation?

Open Task Manager or BIOS and verify the memory shows 8 GB total at DDR3-1333 (PC3-10600) with CL9 timings.

Does the package include only the two 4 GB SODIMMs or are tools and adapters also supplied?

The box contains exactly two 204-pin DDR3 SO-DIMM modules; no tools, adapters or extra cables are included.
