8GB DDR4 2666MHz Desktop Memory

This 8GB DDR4 module runs at 2666MHz with CL19 latency and 1.20V operation. It is an unbuffered non-ECC DIMM designed as a compatible replacement for the Corsair CMK32GX4M4A2666C16 kit. The 288-pin form factor fits standard desktop motherboards supporting DDR4 memory.

Capacity and headroom for everyday workloads

The single 8GB stick adds meaningful capacity for multitasking, office applications and light content creation. Systems with four slots can reach 32GB using four modules, while two-slot boards top out at 16GB. Heavier workloads such as video editing or virtualisation will exhaust 8GB quickly.

CL19 latency at 2666MHz

The CAS latency of CL19 at the rated 2666MHz speed determines responsiveness in latency-sensitive tasks. Buyers should confirm their platform supports this frequency and timing before purchase.

Questions about this item

Will this 8 GB DDR4 2666 MHz module fit a standard desktop motherboard slot?

Yes — it is a 288-pin unbuffered DIMM built to the DDR4 standard, so it installs in any desktop slot that accepts DDR4 memory.

Can I add this stick alongside my existing Corsair CMK32GX4M4A2666C16 modules?

It is sold as a compatible replacement for that exact Corsair part number, matching 2666 MHz speed, 1.2 V voltage and CL19 latency for mixed-kit use.

Does the module need a heat spreader or extra cooling in a typical case?

No heat spreader is included; the 1.2 V DDR4 rating runs cool enough for normal desktop airflow without additional cooling.
