The Samsung M391A2K43BB1-CTD is a 16GB DDR4 memory module that brings dependable speed and capacity to desktop and workstation builds. Running at 2666 MHz, it delivers the bandwidth needed for tasks such as 3D rendering, data analysis, and large-scale multitasking without causing slowdowns.
Its 2R x 8 layout and built-in ECC actively detect and correct single-bit errors, making the module a solid choice for environments where data integrity matters, including engineering labs, content creation studios, and small business servers. The standard 288-pin UDIMM format installs easily into boards that support DDR4 PC4-21300, so upgrades can be completed in minutes.
An operating voltage of 1.2 V helps keep power draw and heat generation in check, which is useful for systems that run heavy workloads around the clock. Combine multiple identical modules for higher total capacity, or drop this single stick into a free slot to give an existing setup a quick performance lift.

- 2R x 8 configuration with ECC support
- 288-pin UDIMM form factor
