Deploying this Samsung 64GB DDR4-3200 RDIMM (M393A8G40AB2-CWECOSM) with dual-rank organization and CL24 latency delivers the memory interleaving and bandwidth consistency required for heavily virtualized servers and in-memory databases. Its registered ECC architecture ensures signal integrity and single-bit error correction, making it the ideal choice for enterprise platforms where data integrity and 24/7 stability under high-capacity workloads are non-negotiable.
1. 64GB capacity per module packs enough density to run more virtual machines per server, reducing hardware footprint while maintaining smooth performance under heavy consolidation.
2. ECC protection automatically detects and corrects memory errors in real time, shielding financial transactions and critical databases from silent data corruption.
3. Registered buffering stabilizes signal integrity across fully loaded memory channels, ensuring dependable operation even when all DIMM slots are populated in a data center rack.
4. 3200MT/s throughput accelerates in-memory analytics and large dataset processing, cutting query response times for business intelligence ifrastructure.
5. Dual Rank interleaving keeps bandwidth utilization high under concurrent access, delivering consistent responsiveness for multi-tenant cloud platforms and containerized microservices.
The Samsung M393A8G40AB2-CWECOSM is a 64GB DDR4-3200 RDIMM engineered for virtualized clusters and in-memory databases. First, ECC error correction is essential: a single bit flip in a hypervisor’s memory space can crash dozens of VMs or silently corrupt transactional data, but ECC detects and fixes these errors on the fly, safeguarding 24/7 uptime. Second, the registered design buffers command signals, dramatically reducing the electrical load on the memory controller. This lets you populate all channels with high-density modules without sacrificing stability, which is critical when scaling to terabytes for an SAP HANA appliance. Third, the dual-rank organization enables rank interleaving, so the controller can access one rank while the other precharges, effectively lowering latency and boosting bandwidth under heavy concurrent queries. Finally, the 64GB capacity and 3200MT/s speed mean you need fewer DIMMs to reach massive memory footprints, preserving both slot space and peak throughput in dense servers. Together, these characteristics ensure your analytics and virtualization infrastructure operates with uncompromising data integrity, linear scalability, and the real-time responsiveness your business demands.
Server Memory Identified
This is a 64GB DDR4-3200 ECC Registered RDIMM (Dual Rank, 1.2V). Designed for server-class platforms, it provides data integrity and high capacity density, ideal for virtualization, databases, and HPC.
General Virtualization
Virtualized hosts with multiple VMs demand both capacity and fault tolerance. Deploy six to eight of these 64GB RDIMMs per dual-socket server (384–512 GB) to comfortably run 20+ moderate VMs. Populate channels symmetrically to maintain balanced memory bandwidth and leverage ECC for maximum uptime.
In-Memory Database
In-memory databases like SAP HANA or Redis require vast, low-latency memory pools. Install 16 or more modules across all channels (1 TB+) to keep entire datasets in RAM. Dual-rank RDIMMs enhance rank interleaving, boosting throughput; always populate identical modules per channel to avoid performance penalties.
High-Performance Computing
HPC workloads benefit from high capacity-per-node and memory bandwidth. Use eight or twelve of these 64GB DIMMs per node (512–768 GB) in a balanced configuration to feed many CPU cores. The registered architecture stabilizes large arrays, while 3200 MT/s speed keeps data flowing to parallel computational kernels.
Rigorously tested server memory, compatible with Dell PowerEdge R760, R750, HPE ProLiant DL380 Gen11, Lenovo SR650, and more.
Q: Can I mix this M393A8G40AB2-CWECOSM with other memory modules of different brands or speeds?
A: Mixing registered ECC server DIMMs with different brands or speeds is strongly discouraged. It may lead to POST failures, instability, or silent data corruption. For predictable reliability, always install identical part numbers with the same rank and timings.
Q: Is this memory compatible with my system?
A: This 64GB DDR4-3200 ECC RDIMM is designed for server platforms, such as Intel Xeon Scalable (Gen 1/2) or AMD EPYC 7001/7002 series. Please check your motherboard’s Qualified Vendor List (QVL) to confirm specific support for this part.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate memory channels evenly across CPUs, typically starting with the farthest slot per channel (e.g., A1, B1, C1, D1). Always follow your server’s service manual for balanced interleaving and optimal memory bandwidth.
Q: Does this module support overclocking or XMP profiles?
A: No, this JEDEC-compliant registered ECC module does not support overclocking or XMP. It runs fixed at 3200 MT/s, CL24, 1.2V. Stability in mission-critical environments takes priority over manual tuning.
Q: What warranty and typical failure rate can I expect?
A: This memory is backed by a 1-year warranty. Enterprise ECC RDIMMs exhibit very low Annual Failure Rates (typically under 0.3%) under standard thermal and workload conditions, making them exceptionally reliable.
