Samsung 32 GB reg. ECC DDR5-6400 M321R4GA0EB2-CCP (M321R4GA0EB2-CCP)

Samsung M321R4GA0EB2-CCP is a registered 32 GB DDR5 server memory module in a single 1 × 32 GB 288-pin DIMM form factor. It operates at 6400 MHz with a 1.1 V supply and includes ECC support and an integrated register to improve clock, command and control signal integrity for server-class stability and data reliability.

Advantages

The registered design reduces signal loading on the memory bus and improves timing stability in multi-module configurations. ECC (with an additional 8-bit parity) provides error detection and correction to protect data integrity. Compatibility with x4/x8 device organization and support for up to two ranks per DIMM enable flexible deployment in 2DPC server configurations.

Suitable for

• Rack and tower servers
• Workstations handling large datasets
• Virtualization hosts and hypervisors
• Database and transaction-processing systems

Key specifications

• Capacity: 32 GB (1 × 32 GB)
• Type: DDR5 registered DIMM (RDIMM)
• Speed: 6400 MHz
• Form factor: 288-pin DIMM
• Voltage: 1.1 V
• Error correction: ECC (with additional 8-bit parity)
• Organization: supports x4 / x8 devices; up to 2 ranks per DIMM; suitable for 2DPC configurations

How to use

Power off the server and follow the system manufacturer’s guidelines for handling memory modules. Align the 288-pin DIMM with the slot keyed notch and press evenly until the retention clips engage. Populate channels and sockets according to the server motherboard manual to ensure proper rank and 2DPC configuration. After installation, power on the system and verify that the BIOS/UEFI recognizes the module and that ECC is enabled if required.

Recommendations

Install matching modules in the same channel for optimal performance and stability. When upgrading, check the server vendor’s memory compatibility list and update firmware/BIOS to the latest recommended version to ensure full support for DDR5 6400 MHz RDIMMs and ECC functionality.
