This DDR4-3200 Registered ECC DIMM with dual-rank x8 organization is purpose-built for server platforms running virtualization, in-memory databases, and data-integrity-critical workloads. Its registered architecture provides signal stability across fully populated memory channels, while ECC error correction and rank interleaving deliver both data protection and improved memory bandwidth under sustained load.
1. Each 32GB capacity enables higher memory-to-core ratios in virtualized clusters, directly increasing the number of VMs a single server can consolidate without performance degradation.
2. ECC protection continuously corrects single-bit errors in the background, preventing undetected data corruption in transactional databases and critical enterprise applications.
3. Registered signal buffering maintains clean command and address integrity under full population, allowing platform architects to scale to maximum DIMM slots with assured stability.
4. Dual Rank x8 organization interlocks independent bank groups to saturate the memory bus, delivering sustained bandwidth for parallel analytics and heavy multi-tenant workloads.
5. The 3200MT/s transfer rate raises ceiling throughput for in-memory computing, shrinking response latency in real-time financial modeling and large-scale caching layers.
Designed specifically for data center and enterprise server environments, the Samsung M393A4G43CB4-CWE is a 32GB DDR4-3200 Registered DIMM that addresses the critical demands of modern IT infrastructure. Its ECC technology proactively detects and corrects single-bit memory errors, effectively eliminating silent data corruption that can crash virtualized clusters or poison financial transactions in an in-memory database like SAP HANA — a non-negotiable safeguard when data integrity directly impacts revenue. The registered signal buffer stabilizes high-density memory configurations, allowing you to populate all channels with confidence that command and address signals remain clean even under heavy load, which directly translates to flawless stability when hosting dozens of virtual machines on a single physical host. Built as a dual-rank x8 module, it leverages rank interleaving to maximize bandwidth and reduce transfer latency; this architecture is vital for memory caching platforms such as Redis, where split-second response times determine user experience and service-level compliance. Operating at a cool 1.2V with a swift 3200MT/s data rate, the module delivers the throughput needed for real-time analytics while lowering total power consumption across a server farm, meaning your TCO drops without compromising the performance that keeps your virtual desktops responsive and your databases accelerating business decisions.
General Virtualization
Install one 32GB DDR4-3200 ECC Registered DIMM per memory channel to balance capacity and bandwidth for multiple virtual machines. In a dual-socket server with 16 channels, 16 modules deliver 512 GB at full 3200 MT/s speed. A 12-module (384 GB) setup also supports moderate VM densities while keeping ECC reliability.
In-Memory Database
Populate all memory channels with 32GB RDIMMs. Start with one DIMM per channel (512 GB in a 16-channel server) for maximum frequency and low latency. When datasets grow, use two DIMMs per channel to reach 1 TB, accepting a speed drop to 2933 MT/s. ECC protection is essential for transactional consistency.
High-Performance Computing
For bandwidth-bound HPC workloads, place a single dual-rank 32GB RDIMM in each channel—16 modules on a dual-socket board provide 512 GB at the full DDR4-3200 data rate. Leave second slots empty to avoid clock downshifting. Use identical, matched DIMMs across all channels to ensure stable, symmetric parallel operations.
Rigorously tested DDR4 ECC RDIMM compatible with Dell R750, HPE DL380 Gen10 Plus, Lenovo SR650 V2, Supermicro SYS-620P-TR.
Q: Can I mix this M393A4G43CB4-CWE with other memory modules of different brands or speeds?
A: Mixing different brands or speeds is not recommended for registered ECC memory. It can cause instability, force all modules to the lowest common speed, or prevent system boot. Use identical modules for assured compatibility.
Q: Is this memory compatible with my system?
A: This DDR4-3200 ECC Registered DIMM is designed for server platforms such as Intel Xeon Scalable or AMD EPYC. Please verify your server board or system qualification list supports 32GB Dual Rank x8 Registered modules at 1.2V.
Q: What is the recommended DIMM population order for optimal performance?
A: For optimal performance, populate identical DIMMs per channel, starting with the slot furthest from the CPU. Typically, fill the first white slot in each channel, then the black slots, balancing memory across all memory controllers.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a server-grade ECC Registered DIMM built to strict JEDEC standards. It does not support overclocking, XMP, or any non-standard speed profiles. It operates reliably at its rated 3200 MT/s.
Q: What warranty and typical failure rate can I expect?
A: This module comes with a one-year warranty. Enterprise-class ECC memory like this typically exhibits a very low annualized failure rate under proper operating conditions, ensuring long-term data integrity.
