8GB DDR4 2666MHz Desktop Module

This single 8GB DDR4 module runs at 2666MHz with CL19 latency and standard 1.2V operation. It uses a 288-pin DIMM form factor and unbuffered, non-ECC architecture. The module is built with major brand chips and tested for AMD and Intel desktop compatibility.

Sustained load behaviour

Quality assurance testing verifies dependable performance under continuous workloads rather than brief bursts. The 1.20V standard voltage helps maintain stable thermals during extended multitasking sessions. Unbuffered design ensures direct communication with the memory controller for consistent throughput.

CL19 latency at 2666MHz

The CAS latency of 19 cycles at the rated 2666MHz speed determines responsiveness for typical desktop tasks. This timing balances bandwidth and access delay for general computing workloads. Verify your motherboard supports DDR4 2666 before ordering.

Questions about this item

How much heat or noise does this 1.20 V DDR4 2666 MHz module add when the PC runs all day?

It operates at the standard 1.20 V DDR4 voltage with no moving parts, so it adds negligible heat and makes no audible noise during continuous use.

What motherboard slot and memory controller does my desktop need to accept this 288-pin DDR4 2666 MHz stick?

A DDR4-compatible motherboard with a free 288-pin DIMM slot and a memory controller that supports 2666 MHz operation is required.

Will this CL19 2666 MHz module run stably alongside my existing DDR4 sticks?

The system will clock all installed modules to the lowest common speed and latency, so this CL19 2666 MHz stick will match slower DDR4 modules automatically.
