SKU CH-42A9-0FJZA

Adds 16 GB of DDR4 memory at 2666 MHz with CL19 timing for desktop upgrades

  • 16 GB capacity supports multitasking and heavy workloads
  • 2666 MHz DDR4 speed moves data quickly through the system
  • CL19 latency keeps response times tight under load
  • PC4-21300 bandwidth rating matches modern desktop platforms
  • Rigorously stress-tested modules deliver reliable operation in critical environments

Samsung 16GB DDR4 2666MHz Memory

This 16GB DDR4 module runs at 2666MHz with a CL19 latency. It is built for desktop systems that need a straightforward memory upgrade. The stick targets everyday office work, web browsing and light multitasking workloads.

16GB capacity at PC4-21300 speed

The single 16GB rank provides enough headroom for typical productivity suites and several browser tabs at once. Performance tapers off when running memory-intensive rendering, virtualization or large dataset workloads that exceed the module's bandwidth and latency envelope.

NEMIX RAM validation and lifetime replacement

Every unit undergoes stress testing under load before shipping to verify stability and compatibility. The supplier backs the module with a lifetime replacement guarantee and US-based technical support for troubleshooting.

Questions about this item

Will this 2666MHz DDR4 module downclock to match my existing slower DDR4 sticks?

The module is rated at 2666MHz with CL19 timings. When mixed with slower DDR4 memory, the system typically runs all modules at the lowest common speed and loosest timings for stability.

How can I confirm the module is running at 2666MHz with CL19 after installation?

Check the memory speed and timings in the BIOS or UEFI firmware screen, or use a system information tool such as CPU-Z to verify the module operates at the rated 2666MHz and CL19 values.

Does the package contain only the 16GB DDR4 DIMM or are extra items included?

The package contains the 16GB DDR4 2666MHz CL19 desktop memory module only. No additional cables, brackets or software are supplied.
