Overview

The Crucial CT2K8G3S1339M is a 16GB memory kit consisting of two 8GB DDR3 SODIMM modules rated at 1333 MT/s (PC3-10600) with CL9 latency. Designed for laptops and compact form-factor systems that use 204-pin SODIMM slots, this kit provides a simple and effective way to boost system memory for improved multitasking, faster application loading, and smoother overall performance on DDR3-based platforms. The dual-voltage design—operating at either 1.35V or 1.5V—ensures compatibility with both standard and low-power DDR3 systems, reducing the guesswork when upgrading.

Manufactured by Crucial, a brand of Micron Technology (one of the world's largest memory producers), these modules are built and tested to meet industry-standard reliability requirements. The matched pair is intended to run in dual-channel mode when installed together, maximizing memory bandwidth for the host system. While DDR3 is now a legacy standard, this kit remains a practical investment for extending the useful lifespan of older notebooks, all-in-one desktops, and mini PCs that cannot accept newer DDR4 or DDR5 memory.

Pros & Cons

👍 Pros

  • 16GB total capacity across two 8GB modules enables meaningful multitasking improvement on older notebooks
  • Dual-voltage support (1.35V and 1.5V) ensures broad compatibility across DDR3 platforms
  • Matched pair ships ready for dual-channel operation without separate module matching
  • Crucial brand backed by Micron, one of the original DRAM manufacturers

👎 Cons

  • DDR3 technology is a legacy standard, incompatible with newer DDR4 or DDR5 systems
  • 1333 MT/s speed is on the lower end of DDR3 specifications, slower than 1600 or 1866 MT/s modules
  • Only suitable for systems with 204-pin SODIMM slots, not standard desktop DIMM slots
  • CL9 latency is adequate but not optimized for performance-tuned configurations

Frequently Asked Questions

This kit fits laptops and small-form-factor devices that use 204-pin DDR3 SODIMMs running at 1333 MT/s (PC3-10600). Check your system's specifications to confirm DDR3 SODIMM support.
Yes, the kit includes two matched 8GB modules designed to run in dual-channel configuration when installed in paired memory slots.
It supports both 1.35V and 1.5V operation (dual voltage), making it compatible with standard-voltage and low-voltage DDR3 platforms.
No, these modules are non-ECC and unbuffered, which is the standard type for consumer laptops and most desktop mini PCs.
