Capacity and purpose

This is a 16GB DDR4 desktop memory module rated at 2666MHz with CL19 latency. It is an unbuffered, non-ECC DIMM intended as a direct replacement for Crucial part numbers CT16G4DFRA266.C8FE and CB16GU2666.

Compatibility checks

Verify that your motherboard accepts DDR4 DIMMs running at 2666MHz and operates at the standard 1.20V voltage. Confirm the board supports 288-pin unbuffered modules and that an available slot can accommodate a single 16GB stick.

Who should buy

Suits anyone upgrading a compatible desktop that needs a straightforward 16GB DDR4 2666MHz module without ECC or a heat spreader. Systems requiring registered memory, ECC error correction, higher speeds, or lower latencies should consider other options.

Questions about this item

Does the module ship as a single 16 GB stick or a kit of two 8 GB sticks?

The product is a single 16 GB DDR4 DIMM (1Rx8, 288-pin). No second module is included; buy a second identical stick only if your board has a free slot.

Should I choose this 2666 MHz CL19 module or a faster CL16 kit for my desktop?

This module runs at the rated 2666 MT/s with 19-cycle latency. Select it when your motherboard specifies DDR4-2666; faster kits will simply down-clock to this speed.

What does the 2666 MT/s rating actually deliver once the stick is installed?

The stick transfers data at 2666 million transfers per second (PC4-21300 bandwidth) at 1.20 V, giving the throughput your CPU and chipset negotiate at that frequency.
