Samsung 16GB DDR4 2933 Module

This Samsung desktop memory module provides 16GB of DDR4 capacity in a single unbuffered UDIMM. It is built for standard desktop systems that use 288-pin slots and operate at 1.2V. The module suits everyday computing, office workloads and general multitasking where ECC error correction is not required.

Capacity and headroom

The 16GB density offers comfortable headroom for modern operating systems, web browsers with many tabs and typical productivity suites. It handles simultaneous applications without paging to slower storage in most common scenarios. Memory-intensive tasks such as large video timelines, heavy virtualisation or extensive data-set processing will exceed this single-module capacity.

Thermals noise and power

Operating at the standard 1.2V DDR4 voltage, the module draws minimal power and generates little heat during normal use. With no heat spreader fitted, it relies on case airflow to maintain safe temperatures under sustained load. The bare green PCB runs silently as there are no moving parts or active cooling components attached.
