16 GB DDR4 DIMM for desktop upgrades

This 16 GB DDR4 module runs at 2666 MHz (PC4-21300) on standard 1.20 V. It is an unbuffered, non-ECC DIMM built to replace Samsung M378A2K43BB1-CTD, M378A2K43CB1-CTD and M378A2K43DB1-CTD parts in desktop systems.

Build fit and freed resources

The 288-pin DIMM plugs into any desktop board that accepts DDR4 UDIMMs, leaving other slots open for additional modules. Adding this single stick increases total memory capacity so the operating system can keep more applications and data in RAM instead of paging to storage.

Thermals noise and power

Operating at the DDR4 standard voltage of 1.20 V keeps power draw low and heat output minimal. The module has no onboard fan, so it adds no acoustic noise to the build. Typical desktop airflow is sufficient to maintain stable temperatures during normal workloads.

Perguntas sobre este artigo

Will the 2666MHz speed hold under continuous heavy workloads?

The module is rated for DDR4 2666 (PC4-21300) at 1.20V and runs unbuffered, so the rated frequency is maintained under sustained load.

How much heat and noise does this 16GB stick produce during all-day operation?

Standard DDR4 1.2V unbuffered DIMMs run passively without fans; they add minimal heat and zero noise to a desktop chassis.

What motherboard slot is required for this 288-pin DIMM to work?

A DDR4 DIMM slot (288-pin) on a desktop motherboard that supports non-ECC unbuffered memory is needed.
