Samsung 4GB PC4-17000 DDR4-2133MHz ECC Registered Memory Module

Overview

The Samsung M393A5143DB0-CPB is a 4GB DDR4-2133MHz ECC Registered memory module designed specifically for servers that require reliable and stable performance. Operating at a low voltage of 1.2 volts, it balances power efficiency with sufficient bandwidth to support virtualization, database management, and file sharing tasks. Its ECC (Error-Correcting Code) capability ensures data integrity by detecting and correcting single-bit errors, making it a dependable choice for critical server environments.

Key features

• ECC support with an additional parity byte to detect and correct single-bit errors, reducing the risk of system crashes and data corruption.
• Registered DIMM design that reduces electrical load on the memory controller, allowing for stable operation when multiple modules are installed.
• Low power consumption at 1.2 volts, helping data centers and server rooms manage energy use without sacrificing performance.
• Single-rank 1Rx8 configuration that fits standard 288-pin RDIMM sockets on many Intel and AMD server motherboards.
• JEDEC-compliant timings for easy installation and automatic BIOS recognition, simplifying upgrades and replacements.
