Samsung 4GB DDR3 PC3-12800 1600MHz ECC Unbuffered Memory Module

The Samsung M391B5273DH0-CK0 is a 4GB DDR3 memory module that brings error-correcting reliability to systems that accept unbuffered DIMMs. Running at 1600 MHz with a PC3-12800 data rate, it can move up to 12.8 GB of data per second, which keeps routine workloads responsive and stable. A 240-pin interface and CAS latency of 11 align with the majority of ECC-capable motherboards found in entry-level servers, scientific workstations, and small business desktops.

Because the module supports ECC technology, it can detect and correct the most common kinds of memory errors before they affect your operating system or applications. That added integrity is particularly valuable in environments where data accuracy matters, such as file servers, financial analysis stations, and CAD machines that run overnight simulations. If you are building or upgrading a platform that must balance cost with dependability, installing this module helps protect against crashes and corrupted datasets without moving to more complex registered memory.
