Compatible upgrade for Toshiba Satellite P755

This 4GB DDR3 SODIMM module is built for the Toshiba Satellite P755-S5269, P755-S5320 and P755-3DV20 notebooks. It installs in a 204-pin slot and runs at 1600MHz with CL11 timing. The unbuffered, non-ECC design matches the original specification for these systems.

Suits owners restoring factory capacity

It fits users replacing a failed stick or filling a single empty socket in the supported models. The 1Rx8 organisation and 1.5V voltage align with the platform requirements. Buyers needing more than 4GB per module or a dual-channel kit should look elsewhere, as this is a single 4GB piece.

Handles everyday workloads within 8GB system limit

The module operates at PC3-12800 speed to support typical office and browsing tasks. The platform maximum is 8GB across two sockets, so a second identical stick would reach that ceiling. Workloads demanding larger memory footprints or higher frequencies will exceed the capability of this upgrade.

Questions about this item

Does my Toshiba Satellite P755-S5269 need a 204-pin DDR3 SO-DIMM slot to use this module?

Yes, this CM5126412800SOSRH module is a 204-pin DDR3 SO-DIMM rated at 1600 MHz and 1.5 V, so the laptop must provide a matching DDR3 SO-DIMM socket.

Will this 1600 MHz stick down-clock to 1333 MHz if I keep the original PC3-10600 module in the second socket?

The module runs at 1600 MHz (PC3-12800) with CL11 timing; when paired with a 1333 MHz stick the system will operate both at the lower 1333 MHz speed.

How can I verify the stick is recognised at 1600 MHz with 11-11-11 timings after installation?

Check the memory tab in CPU-Z or the BIOS memory information screen; it should report 1600 MHz, CL11, 1.5 V and 4 GB capacity for this module.
