Product information

Description

The Samsung M321R8GA0BB0-CQK is a registered 64GB DDR5 288-pin DIMM module operating at 4800 MHz and 1.1 V. Designed for server and high-performance PC use, this memory module includes an on-DIMM register to strengthen clock, command and control signals and offers optional error correction via an additional 8-bit parity signal. The module supports x4 and x8 device organization and up to two ranks per DIMM, allowing common 3DPC (three DIMMs per channel) configurations in compatible systems.

Advantages

The registered design improves signal integrity and stability in multi-module server environments, while DDR5 technology and a 4800 MHz clock speed provide increased bandwidth for concurrent workloads. The availability of 8-bit parity enables error detection to help maintain data consistency. A 288-pin DIMM form factor and standard 1.1 V operation ensure compatibility with DDR5-capable motherboards and servers.

Suitable for

  • Servers and data center systems requiring registered DDR5 memory
  • Workstations and high-performance PCs used for virtualization or large-memory applications
  • Systems configured with multiple DIMMs per channel (3DPC) where register and rank support is needed

Key specifications

  • Manufacturer: Samsung
  • Model: M321R8GA0BB0-CQK
  • Capacity: 64 GB
  • Type: DDR5 Registered DIMM (RDIMM)
  • Speed: 4800 MHz
  • Form factor: 288-pin DIMM
  • Voltage: 1.1 V
  • Organization: x4 / x8
  • Ranks: up to 2 ranks per DIMM
  • Error correction: 8-bit parity (optional)

How to use

Install the module into a compatible DDR5 288-pin DIMM slot on a motherboard or server that supports registered (RDIMM) memory and the specified speed and voltage. Follow the system vendor's guidelines for population rules, especially when using multiple DIMMs per channel (3DPC) and when mixing ranks. Ensure BIOS/firmware is updated to recognize DDR5 RDIMM modules and configure memory settings according to the platform documentation.

Usage recommendations

Use this Samsung 64GB DDR5 4800 MHz registered module in systems explicitly supporting RDIMM and 1.1 V operation; avoid mixing registered and unbuffered modules in the same system. For error-sensitive workloads, enable parity/error features per platform support and follow vendor memory population guidelines for optimal performance and reliability.
