16GB DDR4 2666MHz DIMM

This 16GB DDR4 module runs at 2666MHz with CL19 timing and 1.2V operation. It is built as a 2Rx8 unbuffered DIMM for desktop systems that accept standard 288-pin memory. The part is suited for owners of compatible computers needing a single 16GB upgrade.

Simple DIMM slot installation

Align the notch on the 288-pin module with the motherboard slot and press firmly until the retention clips engage. The product appearance may differ from the reference picture supplied by the manufacturer. Mixing modules from different makers will force all memory to run at the speed of the slowest module or the processor limit.

2Rx8 rank configuration

The module uses a 2Rx8 organisation that determines electrical loading on the memory controller. Systems requiring a single-rank 1Rx8 part may not recognise this module or may run it at reduced stability. Verify the rank requirement before purchase.

Questions about this item

How can I confirm the 16GB DDR4 2666MHz module is running at CL19 after installation?

Check the memory tab in CPU-Z or your BIOS; it should report 2666 MHz with 19-19-19 timings at 1.2 V.

What does the 1-piece 16GB kit include and what must I source separately?

The kit supplies one 288-pin DIMM; any additional modules for dual-channel operation must be purchased separately.

Should I choose the 1Rx8 or 2Rx8 version of this 16GB DDR4 2666MHz DIMM?

This part is the 2Rx8 rank; select it when your system requires dual-rank modules for full capacity support.
