Targeted 4 GB DDR3-1333 SO-DIMM

This 4 GB DDR3 SO-DIMM runs at 1333 MHz with CL7 timing and 1.5 V operation. It is built for owners of Toshiba Satellite C655D-S5300, C655D-S5226 and C655D-S5334 laptops who need a direct replacement or a single-module upgrade. The unbuffered, non-ECC design matches the original specification for these systems.

Fits 204-pin DDR3 slots in compatible notebooks

The module uses the standard 204-pin SO-DIMM form factor and requires a free DDR3 SO-DIMM socket in the laptop. Adding it frees the existing slot for a second module if the board supports dual-channel operation up to the platform limit of 8 GB across two sockets. No heat spreader is fitted, so clearance inside thin chassis is not affected.

Steady CL7 latency under sustained workloads

Rated timings of 7-7-7 at 1333 MHz deliver consistent latency during extended memory-intensive tasks such as large document editing or browser sessions with many tabs. The 2Rx8 organisation and major-brand chipset maintain stable signalling without throttling, while the 1.5 V supply keeps power draw predictable for the laptop's cooling solution.

Questions about this item

What is the CAS latency that governs the first timing limit under sustained use?

The module runs at CL7 with 7-7-7 timings, so the first timing limit you hit is the 7-cycle CAS latency.

How much heat or power does this stick draw when running all day?

It operates at 1.5 V without a heat spreader, so power draw and heat stay low for a 4 GB DDR3 SO-DIMM.

Which Toshiba Satellite models must I already own for this memory to work?

This 204-pin DDR3 SO-DIMM is guaranteed compatible with Satellite C655D-S5300, C655D-S5226 and C655D-S5334.
