Samsung Semiconductor Samsung - DDR5 - modul - 32 GB - DIMM 288-PIN / PC5-51200 - registred (M321R4GA0PB2-CCP)

Samsung M321R4GA0PB2-CCP is a 32 GB registered DIMM designed for server and workstation environments. The module uses DDR5 technology at 6400 MHz in a 288-pin DIMM form factor, operates at 1.1 V and includes ECC support to improve data integrity and reliability under heavy workloads.

Advantages

The registered DIMM includes an on-module register to stabilize clock, command and control signals, reducing electrical load on the memory controller. ECC support is provided via an additional 8-bit parity bus for error detection and correction. The module supports x4 and x8 die organizations, up to two ranks per DIMM and two DIMMs per channel (2DPC) configurations, enabling greater capacity and compatibility in server platforms.

Suitable for

• Enterprise servers
• Virtualization hosts
• Database and analytics servers
• High-reliability workstations

Key specifications

• Capacity: 32 GB (1 x 32 GB)
• Memory type: DDR5
• Speed: 6400 MHz
• Form factor: 288-pin DIMM
• Voltage: 1.1 V
• Error correction: ECC (8-bit parity)
• Module type: Registered DIMM (RDIMM)
• Organization support: x4 / x8; up to 2 ranks per DIMM; 2DPC support

How to use

Install the Samsung M321R4GA0PB2-CCP module into an appropriate 288-pin DIMM slot on a compatible server motherboard following the server vendor's installation procedures. Ensure the motherboard and BIOS/firmware support DDR5 RDIMM modules at 6400 MHz and ECC functionality. When populating multiple channels, follow the motherboard's channel population rules and observe anti-static precautions during installation.

Recommendations

For optimal reliability, use matched RDIMM modules from the same vendor and part number across channels; verify server firmware supports the specified speed and ECC mode, and update BIOS/firmware if needed before deployment.
