This 32GB DDR4-3200 RDIMM with ECC and Registered signaling is purpose-built for server platforms, delivering critical data integrity for virtualization, in-memory databases, and enterprise workloads that cannot tolerate silent corruption. Its Dual Rank x4 configuration and CL22 latency optimize memory bandwidth and interleaving efficiency on multi-channel memory controllers, while the Registered buffer enhances signal stability in high-density deployments.
1. A 32GB capacity per module allows dense memory configurations in virtualization hosts, ensuring ample headroom for simultaneous VMs without swapping to slower storage.
2. The 3200 MT/s data rate delivers high memory bandwidth to keep pace with multi-core server CPUs, accelerating in-memory databases and real-time analytics.
3. ECC protection corrects single-bit errors and detects multi-bit corruption, preserving data integrity in financial transactions and critical enterprise workloads.
4. Registered signal buffering stabilizes high-capacity ranks by reducing electrical loading on the memory controller, enabling large-scale deployments with uncompromised uptime.
5. Dual Rank x4 organization interleaves accesses across internal banks, increasing effective bandwidth and sustaining performance under heavy concurrent request loads.
When you are running an enterprise virtualization cluster or an in-memory database, the Samsung M393A4K40DB3-CWEBQ is not just another component—it is your safeguard against silent data corruption and performance collapse. This 32GB DDR4-3200 RDIMM operates at an energy-efficient 1.2V and uses registered signal buffering, which stabilizes high-density server configurations by reducing electrical load on the memory controller, allowing you to populate all channels without sacrificing speed. The ECC technology actively corrects single-bit errors, a critical defense when a flipped bit in a financial transaction log or a virtual machine’s state could cascade into catastrophic downtime. Its dual-rank x4 organization and CL22 latency are optimized for sustained bandwidth under heavy parallel workloads: imagine a Redis cluster serving millions of operations per second, where interleaving across ranks hides row activation delays and prevents bottlenecks. For your VMware farm or SAP HANA instance, this module ensures that as you scale capacity, data integrity and predictable latency remain absolute—transforming raw gigabyte count into trustworthy, enterprise-grade resilience.
General Virtualization
For a typical dual-socket host, populate one 32GB RDIMM per memory channel (16 modules total) to obtain 512GB at full 3200MT/s. This balanced 1DPC configuration offers ample capacity for moderate VM densities without sacrificing memory bandwidth.
In-Memory Database
Maximize capacity by filling all memory channels; start with one 32GB DIMM per channel, then add a second DIMM (2DPC) if larger datasets are needed. A dual-socket server with 16 channels and 2DPC reaches 1TB of RAM, though speed may drop to 2933MT/s.
High-Performance Computing
Install a single 32GB RDIMM per channel to sustain DDR4-3200 speeds and lowest latency. This yields 512GB on a 16-channel dual-socket node and avoids performance penalties from mixed or 2DPC configurations. Ensure symmetric population across sockets for NUMA balancing.
Rigorously tested server memory, compatible with Dell PowerEdge R760, HPE ProLiant DL380 Gen11, Lenovo ThinkSystem SR650 V3, and more.
Q: Can I mix this M393A4K40DB3-CWEBQ with other memory modules of different brands or speeds?
A: Mixing with different brands or speeds is strongly discouraged. Inconsistent RDIMM characteristics can cause system instability, POST failures, and jeopardize mission-critical operations. Always use identical modules for reliable performance.
Q: Is this memory compatible with my Intel Xeon Scalable or AMD EPYC server platform?
A: This DDR4-3200 RDIMM is standardized for the latest Intel Xeon Scalable and AMD EPYC 7002/7003 series platforms. Please verify your motherboard’s memory QVL or specific CPU model for guaranteed compatibility.
Q: What is the recommended DIMM population order for optimal performance with this RDIMM?
A: For dual-socket servers, populate identical DIMMs per channel evenly across all memory channels. Typically, fill the farthest slots from the CPU first per channel, balancing capacity for optimal memory interleaving and bandwidth.
Q: Does this server memory module support overclocking or XMP profiles?
A: No, this registered ECC module operates exclusively at JEDEC standard DDR4-3200 (PC4-25600) with CL22 timings. Overclocking and XMP profiles are not supported for the stability required in enterprise environments.
Q: What warranty and typical failure rate can I expect for this Samsung module?
A: This genuine Samsung module carries a 1-year warranty. With rigorous factory testing, enterprise DRAM exhibits an extremely low annualized failure rate (AFR), typically below 0.5%, ensuring high mission-critical reliability.
