16GB DDR4 2666MHz Desktop Module

This 16GB DDR4 module runs at 2666MHz with CL19 latency and 1.20V operation. It uses a 288-pin unbuffered DIMM form factor for standard desktop systems. The module is tested as a direct replacement for several Kingston part numbers including KVR26N19S8/16 and HX426C16FB4/16.

Sustained Load Behaviour

Major brand chips are used throughout and every unit undergoes quality assurance testing before shipment. The standard DDR4 voltage of 1.20V supports stable operation during extended workloads. Non-ECC unbuffered design keeps latency low for consistent responsiveness under pressure.

CL19 Latency at 2666MHz

The CAS latency of 19 cycles at 2666MHz determines how quickly the memory responds to read requests. This timing suits general desktop computing and multitasking scenarios. Verify your system supports DDR4 2666 before purchase to ensure compatibility.

Questions about this item

How much heat and power does the 1.20 V DDR4 2666 module draw when it runs all day?

At the standard 1.20 V the 16 GB stick stays within normal DDR4 thermal limits and adds only a modest load to the system power budget.

What must my motherboard already provide for this 288-pin DIMM to work?

A DDR4 slot that accepts 2666 MT/s unbuffered non-ECC memory at 1.20 V.

Will this CL19 stick run stably alongside my existing 2666 MHz modules?

Yes, it matches the 2666 speed and 1.20 V voltage, so the memory controller can train both kits at the same timings.
