About the Samsung DDR5 128GB RDIMM 5600MHz
Operating at CL46 latency with 1.1V voltage, the Samsung DDR5 128GB RDIMM 5600MHz module delivers the precision timing and low power consumption critical for high-frequency trading platforms and in-memory databases. This is a registered DIMM (RDIMM) built on Samsung's DDR5 architecture, offering 128GB capacity at 5600 MT/s with quad-rank (4Rx4) organization and x4 DRAM die configuration. The 288-pin design incorporates a DDR5 RCD Gen2 register clock driver and dual error-correction layers—both on-die ECC (ODECC) and system-level ECC—ensuring data integrity in mission-critical deployments. Part number M321R8GA0BB6-CWMQ, this module stands 31.25mm in height and operates reliably across 0°C to 85°C, meeting RoHS compliance standards for enterprise environments.
Samsung's commitment to reliability makes this DDR5 RDIMM particularly attractive to storage architects, database administrators, and IT procurement teams responsible for large-scale server farms and virtualization infrastructure. The quad-rank configuration and registered design minimize signal degradation across densely populated memory channels, while the combination of on-die and system ECC provides defense-in-depth against soft errors—essential for 24/7 uptime commitments. Organizations deploying multi-socket systems, hyperconverged infrastructure, or workloads demanding sub-50ns memory latency will find the CL46 timing and 5600 MHz speed optimized for throughput without thermal stress.
