Samsung - DDR5 - module - 32 GB - DIMM 288-PIN - 6400 MT/s / PC5-51200 1.1 V registered ECC

Memory module Samsung M321R4GA3EB2-CCP is a registered 32 GB DDR5 DIMM designed for server and workstation platforms that require error-correcting memory. This single-rank or dual-rank 288-pin module operates at 6400 MT/s and 1.1 V, includes a register to enhance command and control signal integrity, and provides ECC support via an additional 8-bit parity path to improve data reliability and system stability.

Advantages

The registered design reduces electrical load on the memory controller and improves signal timing for multi-module server configurations. ECC support detects and corrects single-bit errors, contributing to higher data integrity in enterprise workloads. Operating at 6400 MT/s while maintaining a low 1.1 V supply offers a balance of performance and energy efficiency for modern server environments.

Suitable for

• Server memory expansion in rack and tower servers
• Workstations performing data analysis or virtualization
• Enterprise applications requiring high availability and data integrity
• Systems configured with multi-channel memory and 2DPC (two DIMMs per channel)

Key specifications

• Capacity: 32 GB
• Type: DDR5
• Form factor: 288-pin DIMM
• Data rate: 6400 MT/s
• Voltage: 1.1 V
• Registered DIMM (RDIMM) with integrated register
• Error correction: ECC with 8-bit parity signals
• Organization: supports x4 and x8 device organizations; up to 2 ranks per DIMM
• Colour: green PCB

How to use

Install the module into a compatible 288-pin DIMM slot on a server or workstation motherboard that supports DDR5 RDIMM and the 6400 MT/s speed grade. Ensure the system is powered off and discharged before insertion, align the notch on the module with the slot key, and press evenly until the retention clips engage. After installation, verify the module is detected in system firmware/BIOS and configured for ECC operation if required by the platform.

Recommendations

For optimal stability, populate memory channels according to the server vendor’s guidelines and use matched modules when building multi-DIMM configurations. Confirm BIOS/firmware support for RDIMM, ECC, and the 6400 MT/s data rate; apply firmware updates if necessary. Avoid mixing different memory speeds or types in the same system to maintain predictable performance and error-correction behavior.
