About the Samsung 32GB DDR5-6400 RDIMM Server Memory
A single Samsung 32GB DDR5-6400 RDIMM module establishes the memory foundation for enterprise servers requiring DDR5 performance at scale. With 32GB capacity per DIMM, infrastructure architects can build systems that maximize memory density while maintaining the reliability standards demanded by mission-critical workloads. This Samsung module (part number M329R4GA0PB0-CQK) combines high-speed DDR5-6400 operation with registered DIMM architecture, making it the preferred choice for IT procurement teams deploying next-generation Xeon and EPYC platforms.
The M329R4GA0PB0-CQK delivers 6400 MT/s performance with tight CAS latency of CL52 and timings of 52-51-51, engineered for consistent throughput in virtualized and containerized environments. Samsung's implementation includes full Error-Correcting Code (ECC) support with On-Die ECC (ODECC), dual-rank 2Rx4 configuration, and a robust 10-layer PCB design rated for 0°C to 85°C operation. The module draws 1.1V and arrives fully RoHS-compliant, meeting sustainability requirements across regulated enterprise deployments. Compatible with Intel Xeon Scalable (Sapphire Rapids+) and AMD EPYC DDR5-capable generations, this 288-pin DIMM integrates seamlessly into certified server platforms.
Enterprise Deployment Scenarios
- Virtualization hosts supporting 100+ concurrent virtual machines with isolated memory guarantees via ECC protection
- Database servers running in-memory analytics platforms requiring sub-50ns access latency
- High-performance computing clusters where dual-rank architecture minimizes memory controller contention
- Hybrid cloud infrastructure nodes balancing workload density with fault tolerance through On-Die ECC
- Data center refresh cycles requiring DDR5 speed upgrades on current-generation Sapphire Rapids and EPYC platforms
