SAMSUNG 16GB DDR4 2666MHz CL19 288-pin DIMM desktop RAM

SKU CH-9MQJ-SDWN5

16 GB DDR4 desktop module at 2666 MHz, CL19, 1.2 V, 288-pin unbuffered non-ECC

  • 16 GB capacity handles heavy multitasking
  • 2666 MHz speed delivers fast data throughput
  • CL19 latency supports responsive performance
  • 2 V operation reduces power consumption by up to 40%
  • 288-pin DIMM fits standard desktop motherboards

Capacity and Speed

This Samsung module delivers 16GB of DDR4 memory rated at 2666MHz with CL19 latency. The 288-pin DIMM operates at 1.2V and uses unbuffered, non-ECC chips. It is built for desktop PCs that need a straightforward capacity increase without overclocking complexity.

Compatibility Fit

The stick suits owners of standard desktop boards that accept DDR4-2666 unbuffered DIMMs and do not require error-correcting code. Builders assembling servers, workstations needing ECC, or laptops requiring SO-DIMM form factors should look elsewhere.

Deciding Specification

The single figure that confirms fit is the 288-pin DDR4-2666 unbuffered non-ECC profile. If the motherboard manual lists that exact specification the module will slot in and run at its rated 2666MHz speed.

Questions about this item

Does my motherboard need a 288-pin DDR4 slot to install this 16GB module?

Yes, this module uses the standard 288-pin DIMM form factor for DDR4 desktop memory and requires a compatible DDR4 slot.

Will this CL19 2666MHz stick run at its rated speed alongside my existing 2133MHz DDR4 memory?

The system will typically downclock all modules to the lowest common speed, so this 2666MHz module will run at 2133MHz when paired with slower DDR4.

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

Check the memory speed and latency reported in your BIOS or a system information tool such as CPU-Z to verify 2666MHz and CL19 operation.
