CMS 4GB DDR3 SODIMM for Satellite L755-S5112

This 4GB DDR3 SODIMM module is built for the Toshiba Satellite L755-S5112 laptop. It uses a 204-pin unbuffered, non-ECC design with CL7 timing at 1.5V. The single stick upgrades system memory for everyday tasks and multitasking on this specific model.

Replaces slower or smaller DDR3 modules

The laptop supports up to 8GB across two sockets. Adding this 4GB stick is worthwhile when the current memory limits multitasking or forces heavy paging. The jump matters most if the system runs a single lower-capacity module or operates at a slower DDR3 speed.

Fits the 204-pin SODIMM slot in the Satellite

No heat spreader is included, so it seats cleanly in tight notebook chassis. The module leaves the second socket free for a matching 4GB stick to reach the 8GB maximum. It requires no BIOS changes beyond standard DDR3 recognition.

Questions about this item

Will this 204-pin SODIMM fit the memory slot in my Toshiba Satellite L755-S5112?

Yes, the module matches the 204-pin DDR3 SO-DIMM form factor used by the Satellite L755-S5112, which has two SODIMM sockets supporting up to 8 GB total.

What is the correct way to seat the module so the laptop recognises the full 4 GB?

Insert the stick at roughly a 30-degree angle until the gold contacts disappear, then press down firmly until both side clips click into the notches on the PCB.

When should I expect to replace this DDR3 stick in the Satellite L755-S5112?

DDR3 memory has no moving parts and typically lasts the life of the laptop; replace only if diagnostics report errors or you upgrade to the maximum 8 GB capacity.
