Samsung M321R4GA3BB6-CQK 32G DDR5 4800 RDIMM
The Samsung M321R4GA3BB6-CQK is a 32GB DDR5-4800 ECC Registered DIMM (RDIMM) built for enterprise servers, cloud platforms, and data center deployments. It suits buyers provisioning virtualization hosts, database nodes, or cache-tier servers on DDR5 platforms that require registered memory with ECC protection. Note that it operates at 1.1V with CL40 latency and, as a DDR5 RDIMM, cannot be mixed with DDR4 modules or unbuffered desktop memory on the same board.

Good to know
- Compatibility check first: DDR5 RDIMMs only fit server/workstation platforms with DDR5 registered-memory support and will not work alongside DDR4 RDIMMs or consumer UDIMMs; confirm your CPU and motherboard qualified memory list (QVL) before ordering.
- Within Samsung’s DDR5 RDIMM family, this module pairs 32GB capacity with 4800 MT/s at CL40 and a dual-rank 2Rx8 layout — dual-rank modules can improve memory bandwidth utilization on capable controllers, but population rules per channel should follow your server vendor’s guidance.
- Buying tip: when scaling capacity across channels, order identical part numbers and rank configurations to keep channel population symmetrical and avoid BIOS-level training issues during boot.
