Samsung 8GB DDR4-2133 ECC UDIMM Memory Module

The Samsung M391A1G43EB1-CPB is a memory module that provides 8 GB of DDR4 capacity, runs at 2133 MT/s, and includes error correcting code to catch and repair single-bit faults in real time. Built in a UDIMM layout, it mates with 288-pin ECC slots while drawing only 1.2 V, an advantage for servers and workstations that need dependable performance without extra heat or power draw.

Samsung arranges eighteen 512M x 8 chips across two ranks, a design that lets the memory controller access data more efficiently during heavy multitasking, virtualization, or database activity. The integrated ECC logic adds a safeguard against data corruption, keeping operating systems and applications stable even under continuous, mission-critical workloads.

System administrators upgrading rack servers, creators assembling a professional desktop for rendering, and researchers running long simulations will all appreciate the straightforward installation: snap the module into a compatible ECC UDIMM slot, confirm recognition in BIOS, and the system gains both capacity and reliability immediately. The module’s low-voltage operation and server-grade error protection make it an easy fit wherever data integrity matters most.

Highlights:

• 8 GB DDR4 capacity in a UDIMM form factor
• 2133 MT/s data transfer rate
• ECC support for single-bit error correction and detection
• Dual-rank x8 (2R x 8) organization with 18 components
• 1.2 V operating voltage for reduced power consumption
• 288-pin configuration compatible with ECC-capable motherboards
