The Samsung M391B1G73BH0-CK0 is a high-quality 8GB DDR3 ECC UDIMM memory module designed for servers and professional workstations that require reliable error correction and stable performance.
This module operates at DDR3-1600 MHz (PC3-12800) and features ECC (Error-Correcting Code) technology, which automatically detects and corrects memory errors to ensure system stability and data integrity. As an unbuffered DIMM (UDIMM), it is compatible with systems that support ECC UDIMM memory and should not be mixed with registered (RDIMM) or buffered modules.
The memory is built using 18 FBGA (78-ball) DRAM chips, each with a 512Mx8 configuration, providing a total organization of 1Gx72. Samsung’s manufacturing quality ensures long-term reliability, making this module suitable for continuous operation in demanding environments.
