16GB DDR4 2666MHz Desktop Module

This 16GB DDR4 DIMM runs at 2666MHz with CL19 latency and 1.20V operation. It is built as an unbuffered non-ECC module using major-brand chipset components. The stick serves as a direct replacement for the Corsair CMK32GX4M2A2666C16 part number.

Sustained-load behaviour

Under continuous workloads the module maintains its rated 2666MHz frequency at the standard 1.20V without a heat spreader. Quality-assurance testing verifies stable operation across extended sessions rather than brief bursts. The 2Rx8 organisation supports consistent throughput for multitasking and heavier desktop tasks.

Pin count and form factor

The stick uses a 288-pin DDR4 DIMM form factor that fits desktop motherboards designed for DDR4 memory. Compatibility depends on the board accepting 2666MHz unbuffered non-ECC modules at 1.20V. Verify your system specifications before purchase to ensure the correct match.

Questions about this item

Will this 16 GB DDR4 2666 MHz module work in a desktop that only supports 21300 MT/s?

Yes, the module is rated for PC4-21300 and will run at the speed your motherboard allows, up to 2666 MHz.

Does the lack of a heat spreader affect reliability in a standard desktop case?

No, the module runs at the standard 1.2 V and is tested for stable operation without a heat spreader in typical desktop airflow.

Is this a single 16 GB stick or a 2 × 8 GB kit?

It is a single 16 GB DIMM, so you add one module to an empty slot or replace an existing stick.
