## Summary description

Registered (buffered) RDIMM memory module Samsung DDR5, 16 GB capacity, 4800 MHz clock speed, 288-pin DIMM form factor and 1.1 V operating voltage. OEM package designed for PCs and servers that require registered DDR5 memory for improved stability and scalability. Suitable for system upgrades, server deployments and memory expansion where ECC/registered modules are required.

## Long description

The Samsung M321R2GA3BB6-CQK is a registered 288-pin DIMM module with 16 GB of DDR5 memory operating at 4800 MHz. It supports ECC through an additional 8-bit parity signal and is designed to improve signal integrity and stability in server-class systems. The module supports x4/x8 device organization and up to two ranks per DIMM, suitable for multi-DIMM per channel (3DPC) configurations.
Advantages
Registered DIMM architecture adds a register to buffer clock, command and control signals for improved signal integrity in high-density memory configurations. ECC parity support helps detect and reduce the risk of data corruption. DDR5 technology and a 4800 MHz data rate provide increased bandwidth compared with previous generations while maintaining a standard 288-pin DIMM form factor compatible with servers that support DDR5 RDIMM modules.
Suitable for
Server platforms requiring registered ECC DDR5 memory
High-density memory configurations (multi-DIMM per channel, up to 3DPC)
Workloads where data integrity and system stability are important (databases, virtualization, enterprise applications)
Key specifications

How to use
Install the module into a compatible DDR5 server motherboard slot following the server vendor's instructions for handling RDIMM modules. Ensure the system BIOS/firmware supports DDR5 registered ECC modules and configure memory population according to the motherboard's recommended DIMM slot order, particularly when using multiple ranks or 3DPC configurations. Power down the system and disconnect power before installing or removing memory modules.
Usage recommendations
Use this module in systems that explicitly list support for DDR5 RDIMM (registered) memory and ECC; consult server compatibility lists and update firmware as needed. For best stability in multi-DIMM configurations, follow the motherboard vendor's guidelines on rank and channel population and test memory with appropriate diagnostics after installation.
