Kingston 16GB DDR4 module

This 16GB DDR4 DIMM runs at 2666 MT/s with CL19 timings at 1.20 V. It uses a standard 288-pin unbuffered non-ECC design and includes an Intel XMP 2.0 profile for automatic configuration. The module is built for desktop systems that accept DDR4 memory.

Thermals and power

Operating at 1.20 V keeps power draw low and heat output modest during normal workloads. No heat spreader is fitted so the module relies on case airflow for cooling. Silent operation is assured because there are no moving parts.

Upgrade context

This single 16GB stick suits builds that need a direct capacity increase without populating every slot. Systems limited to DDR4 2666 will run at the rated speed without manual tuning. Buyers who want higher frequencies or lower latencies should look elsewhere.

Questions about this item

Will this 16 GB DDR4 module fit a standard 288-pin desktop DIMM slot?

Yes, the module uses the 288-pin DIMM form factor and 1.2 V DDR4 electrical standard used by current desktop platforms.

Does the CL19 latency at 2666 MT/s require manual BIOS tuning or does it load automatically?

The kit includes an Intel XMP 2.0 profile so the rated speed and timings can be enabled with a single BIOS selection.

Is ECC or registered buffering included for server or workstation use?

No, this is a non-ECC unbuffered DIMM intended for standard consumer desktop motherboards.
