Samsung 48GB DDR5 6400 Mbps Server Memory Module

Overview

The Samsung M321R6GA3PB2-CCP is a 48GB DDR5 Registered DIMM designed specifically for servers that require fast and reliable memory performance. Operating at a data rate of 6400 Mbps and a nominal voltage of 1.1 V, this module balances high bandwidth with efficient power consumption, making it well suited for data centers and enterprise environments. Its error correction capabilities and buffered signals ensure stable operation even in demanding multi-DIMM configurations.

Key features

• Registered DIMM with on-board register buffers clock, command, and control signals to reduce electrical load on the memory controller, enhancing signal integrity.
• ECC with 8-bit parity detects and corrects single-bit errors, protecting critical workloads from data corruption and system crashes.
• Designed with a 2R x 8 organization using x4 and x8 DRAM devices to maximize capacity while maintaining compatibility with current DDR5 server platforms.
• Operates at a low 1.1 V voltage to help limit power consumption in dense server racks, supporting energy-efficient data center operations.
• Compatible with systems that support dual DIMMs per channel, allowing for flexible memory scaling in rack, blade, or tower servers.
