Computer Memory Solutions 4GB DDR3 1333 CL7 2Rx8 SODIMM memory upgrade

SKU CH-EEAT-5QF8H

A 4 GB DDR3 SODIMM running at 1333 MHz with CL7 latency for compatible Toshiba Satellite laptops

  • Total capacity4 GB
  • Rated speedDDR3 1333 (PC3 10600)
  • ChipsetMajor Brand Chipset
  • CAS latencyCL7
  • Memory timings7-7-7
  • Rated voltage1.5 V
  • 4GB capacity expands multitasking headroom on compatible Toshiba Satellite models
  • DDR3 1333 MHz speed matches factory memory specification for stable operation
  • CL7 CAS latency provides responsive timing for everyday workloads
  • 204-pin SO-DIMM form factor fits the two available memory sockets directly
  • Unbuffered non-ECC design installs without configuration on supported laptops

Capacity and Compatibility

This 4GB DDR3 SODIMM module is designed as a direct memory upgrade for Toshiba Satellite L755D-S5218, L755D-S5204 and L755D-S5250 notebooks. It uses a 204-pin form factor and operates at 1.5V without ECC or buffering. The single stick provides a straightforward capacity increase for compatible systems.

Sustained Operation Behaviour

Rated at DDR3 1333 (PC3 10600) with CL7 7-7-7 timings, the memory maintains its specified latency and frequency during continuous workloads. The 2Rx8 organisation distributes access across two ranks using 256x8 major brand chips. No heat spreader is fitted, so thermal performance relies on the notebook's internal airflow.

DDR3 Interface Limits

The DDR3 SO-DIMM standard used here tops out at 1600 MHz (PC3 12800), above this module's 1333 MHz rating. The target platforms support a maximum of 8GB across two sockets, so a single 4GB stick leaves one slot free for a matching module. Systems requiring ECC, registered buffers or voltages other than 1.5V cannot use this kit.

Questions about this item

Does the 1.5 V DDR3-1333 SODIMM run hot or draw extra power during long sessions?

It operates at the standard 1.5 V for DDR3 and has no heat spreader, so thermals and power draw match ordinary laptop memory.

What does my laptop need already so this 204-pin module will install and be recognised?

A free DDR3 SO-DIMM slot and a BIOS that accepts 4 GB PC3-10600 CL7 unbuffered modules.

Will this 2Rx8 stick work beside the original 1Rx8 module in my Satellite L755D?

Yes, the laptop supports mixed-rank DDR3 up to 8 GB total across its two sockets.
