About the Samsung 16GB DDR4 RDIMM - DDR4
Samsung DDR4-2933 16GB RDIMM (PC4-23400) delivers registered memory performance for enterprise-grade server builds. The M393A2K43DB2-CVF module combines dual-rank architecture with full SECDED ECC protection, making it the standard choice for mission-critical infrastructure where data integrity cannot be compromised.
This Samsung registered DIMM operates at 1.2V with CAS latency 21 and primary timings of 21-21-21, engineered for 2Rx8 configuration across 288-pin sockets. Built on 10nm-class DRAM die technology, the module includes on-die ECC, SPD detection, and full JEDEC DDR4 RDIMM compliance. Storage architects and IT procurement teams select this part for high-availability systems requiring error correction and thermal stability across extended operating ranges (0–85°C). The standard 31.25mm height ensures compatibility with dense rack-mounted server chassis.
Typical Enterprise Deployment Scenarios
- Virtualization platforms requiring ECC protection across 20+ concurrent guest machines
- Database servers running transaction-heavy workloads (SQL Server, Oracle) with write-intensive operations
- High-performance computing clusters where single-bit error detection prevents silent data corruption
- Backup and disaster-recovery appliances demanding consistent uptime and fault tolerance
- VMware vSphere and Hyper-V environments scaling beyond 256GB total RAM per node
The M393A2K43DB2-CVF is engineered for integration into 2-socket or 4-socket Xeon platforms, supporting memory configurations up to 12 or 24 DIMMs per system depending on architecture. Samsung's registered buffer isolates module noise from the CPU memory controller, extending reliability in high-density deployments. Organizations across MENA region healthcare, financial services, and government sectors rely on this module for regulatory compliance and SLA commitments.
