Micron-compatible DDR4 module

This 16 GB DDR4 2666 UDIMM is built with Micron chips and tested for Micron-based systems. It runs at 1.2 V with CL19 latency and a 2Rx8 rank layout. The unbuffered, non-ECC design fits standard 288-pin desktop DIMM slots.

Desktop upgraders needing Micron-validated RAM

It suits owners of Micron-qualified desktops or workstations who want a single 16 GB stick without ECC or registered buffering. Builders requiring ECC error correction, registered modules, higher speeds or lower latencies should look elsewhere.

Drops into a 288-pin DDR4 slot

The module needs a motherboard that accepts 2666 MT/s DDR4 UDIMMs at 1.2 V. It leaves other slots free for matching sticks and adds capacity without raising voltage or changing memory topology.

Questions about this item

Does my motherboard need a free 288-pin DDR4 DIMM slot for this 16 GB module?

Yes, the module is a 288-pin DDR4 UDIMM that installs in a standard desktop DDR4 slot.

Can I keep my existing DDR4 2666 CL19 sticks and add this 2Rx8 16 GB module?

It will run at the speed and timings of the slowest module; matching rank and voltage helps stability.

How do I confirm the 2666 MT/s speed and CL19 latency are active after install?

Check the memory tab in CPU-Z or the BIOS main screen; both should show 2666 MT/s and CL19.
